WeatherWatcher: Wind Advisory issued for Tuesday

Monday, December 26, 2022

The National Weather Service in Seattle has issued a wind advisory for the greater Puget Sound region, including the Shoreline and Lake Forest Park areas. The wind advisory is in effect from 7am on Tuesday until 1am Wednesday morning. Wind gusts of 50mph are possible, with a slight chance of wind gusts exceeding 60mph.

Winds are expected to peak in the area at around 4pm or 5pm Tuesday evening. In general, strong winds are expected to last 6-8 hours on Tuesday compared to Monday morning's short burst. More power outages are expected with this storm, especially with the moist soil conditions. 

Another round of heavy rain is preceding this wind event adding around another 3/4 of an inch of rain to the already saturated ground. There is also a Flood Watch in effect until Wednesday afternoon. Significant amounts of rain with snow melt have added an increased risk of landslides in the area.

A cloudy, rainy, and mild weather pattern is expected to continue into the New Year. There is some potential for another windstorm to arrive sometime around Friday. I will write another weather article when details become clearer on that storm system.

Monday morning, we had a short burst of winds with a strong cold front that moved through around 7am. Winds at SeaTac airport gusted to 55mph, while at Paine Field in Everett winds gusted to 49mph.

We recorded a gust of 31mph at the Shoreline Weather Richmond Beach station. Another personal station near the Puget Sound in Shoreline on Weather Underground recorded a gust of 52mph.

WeatherWatcher: Winter storm watch Thursday afternoon through Friday evening

Thursday, December 22, 2022

 
Freezing rain event in February 2021
Photo by Carl Dinse
The National Weather Service in Seattle has issued a Winter Storm Watch in effect for Thursday afternoon into Friday evening. This is for our next winter storm that is expected to move into the area before we thaw. A messy wintery transition is expected to happen Friday morning through afternoon.

  • First Act: Accumulating snow (1-3 inches)
  • Second Act: Accumulating freezing rain ( 0.0 to 0.25 inches )
  • Gradual warm up starting Friday morning - moving above freezing Friday evening.
  • Potential flooding rains over the weekend, with potential for wind.

Temperatures Wednesday night and Thursday night are expected to dive into the teens to low 20's. An approaching Pacific storm is moving in from the southwest. This storm has sub-tropical origins and is very warm, but we have very cold air in place before and as it arrives.

Precipitation is expected to start around Thursday afternoon in the 1pm to 3pm time frame, starting mainly as light snow for the most part. We could see an additional 1-3 inches of snow accumulation before freezing rain begins mixing in during the overnight hours into Friday. 

The precipitation that arrives Thursday afternoon is expected to continue non-stop through Saturday and beyond. Around 1am to 3am Friday morning the atmosphere is expected to warm up enough for that snow to change over to rain or mix with rain. 

Temperatures at the ground level though are expected to remain below freezing, which means freezing rain. Around a quarter of an inch of freezing rain accumulation is possible from Friday morning through Friday evening.

This kind of event can put a lot of weight on trees and power lines, and it is expected that scattered power outages will occur. Travel will also be extremely difficult as roads become glazed in ice on top of new snowfall.

Once we get through Friday temperatures are expected to warm to the upper 40's or low 50's. It'll feel very nice compared to the temperatures we've had for all of December so far. With the warm air comes a lot of rain. 

We have a large atmospheric river approaching that could bring us 4-6 inches of rain through the holiday weekend. Urban flooding and stream flooding will be our next concerns as everything melts and the heavy rains arrive.

There is a lot of uncertainty in our forecast for this transition over to rain and for coming events through the weekend. Snow or freezing rain could linger several hours longer than forecasted. 

Another item in the forecast is potential for a wind event. The general trend for the remainder of the month looks to be an active and seasonal pattern. A lot of rain, and potential for one or several wind events on the horizon.

WeatherWatcher: Snowy and cold week ahead

Monday, December 19, 2022

 
Snow covered trees on December 18, 2022

Some light snow arrived Sunday, December 18, 2022 just a couple hours later than it did 32 years ago, which was a far bigger storm

As of 6pm Sunday evening about an inch of snow had accumulated at the Richmond Beach station. 

Around the same time, the lower reaches of Lake Forest Park were bare, with rain falling. Higher up, in central Shoreline, there was also about an inch accumulation with snow still falling.

Doppler Radar Sunday December 18, 2022 at 10:29pm
National Weather Service in Seattle, Wa

As of Sunday evening, at 10:29pm an active convergence zone centered over the King / Snohomish County line continues. Another 1-2 inches of snow is possible before the activity dies down by the early morning hours. Temperatures are expected to remain below freezing between Sunday evening and Thursday. There might be a brief warm up Tuesday afternoon into the mid-30's with a storm.

Forecast: Monday should be a cloudy, cold, but mostly dry day. A renewed slight chance of snow showers may show up late Monday night into Tuesday morning. Temperatures are expected to remain below freezing, reaching around 30-31°F for a high temperature, with lows in the lower to mid 20's.

Tuesday's storm: A storm west off the Pacific Ocean is expected to move in, with the center of the storm track just south of Seattle. Some models have it coming in south of Olympia. Either way, everyone on the north side of the storm track is expected to remain all snow and below freezing during this event. 

There's a slight chance some warmer air might mix in up to even Everett for a very short time during the Tuesday storm which might make the snow heavier and wet, maybe with a few rain drops mixed in at times. This warm period is expected to be very short lived, maybe about an hour or so late in the afternoon.

Total snow accumulations from Tuesday's storm could be in the range of 3-10 inches depending on how far south this storm tracks. If it comes in closer to Seattle it could be higher amounts for those of us north of downtown Seattle.

Lows Tuesday night through Thursday night are expected to be in the low 20's, we could even reach the teens Wednesday morning. 

Wednesday and beyond: We get a bit of a break Wednesday, but not from the cold. Any snow we receive will stick around for the remainder of the week. Another storm rolls in Thursday afternoon into Friday. At this time models think a transition will occur Friday with milder temperatures and rain with a possible atmospheric river though the holiday weekend.

Bottom line: Be prepared for a full week of winter conditions including accumulated snow on the ground. Next weekend at this time shows a shift to some above freezing rain but that could easily change over the next few days. We could be intermittently in and out of winter weather for the next several weeks through January.

There is a huge arctic air mass hanging out in Western Canada now that traveled over from Siberia last week. It is very cold, saturating the temperature charts at -58°F in places and even showing up on infrared satellites. 

The arctic air mass is expected to be in Western Canada through next weekend and beyond so any storm that tracks south of Seattle could pull some of that air down into the Puget Sound region and keep us on the below freezing side with snow instead of rain.

WeatherWatcher: Tuesday Storm report, more potential snow on the way

Thursday, December 1, 2022

 
Tree and power lines down on 25th Ave NE near NE 178th St.
Photo by Amy Beth Nolte

I'm going to start out by saying in my 35+ years of living memory in Shoreline, this is by far the most tree damage I've ever witnessed from any given storm. Locally, this far exceeds the major convergence zone snowstorm of December 18, 1990, or the Inauguration Day windstorm of January 1993. The 1993 storm had power out in my neighborhood for over 3 days, the 1990 storm knocked power out for almost 24 hours in my neighborhood.

This past Tuesday's storm, that same neighborhood was without power for 41 hours. Neighbors had set up a large fire pit on the street side for everyone to come warm up at, and to help dispose of some of the fallen tree matter. We have piles and piles of tree branches cleaned off the road and pushed to the sides just to get the street passable. Snow accumulations in yards were covered under a solid accumulation of tree matter.

Power lines down near the North Ridge weather station.

There were several downed utility lines that had to be coiled up and set aside out of the traffic lanes. Many partially fallen or split trees in the Echo Lake neighborhood leaning on utility wires. Driveways blocked by fallen debris or power lines was common sight throughout the areas I drove through.

As the storm was wrapping up early Wednesday morning, most of the area was without power. There was about 5 to 7 inches of heavy wet snow on trees and the ground. 45mph winds had pushed a lot of that snow into heavy snow drifts on the southeast sides of trees and any other exposed objects.

Winds combined with the unusually wet and heavy snow is what lead to the massive tree damage in the area. Temperatures particularly in the atmosphere above us were warm enough that snow was intermittently mixing with rain. Since the air near the surface was near or below freezing all that moisture in any form ended up clinging to everything and freezing once it landed.

Shoreline ended up being very much at the transition point of this storm system. Doppler radar indicated rain just south of 145th Street in Seattle and heavy snow north into Shoreline. The rainfall equivalent was nearly 1 inch of rain in this storm. Later in the evening the rain in north Seattle transitioned over to snow as the cold front pushed south.

City Light power outage map at 1:20 am November 30th


As you can see from the outage map, most of the highland areas of Shoreline and Lake Forest Park were without power during the height of the storm. There are still a lot of broken tree limbs caught up in the tree canopy that may be coming down in future storms. Once the tree limbs settle, I think we'll see less power outages for a while as this storm has pretty much pruned out all the weak branches in our forest.

Forecast: We have another storm system working its way down the Pacific coast from the northwest. Models have been all over the place on what to expect from this system. Some show a rain/snow mix, most are showing snow accumulations of 1-5 inches. There is much uncertainty in the forecasts.

Given how the other system went, I'm leaning towards the snowy version for this forecast. We could see rain and snow mixed here and there, but likely we will get some light to moderate snow accumulations out of this one as well. 

Timing wise, it'll be like Tuesday, light snow, or rain/snow mixed could start up late Friday morning to early afternoon. The heavier stuff is expected Friday evening after around 4pm or so. Snow levels are expected to hover around 200-500 feet during the warmer parts of the day and could drop all the way down to sea level in the overnight hours.

There are no winter weather advisories, watches, or warning currently. In general, for the longer-range forecast, we're looking at this cool to cold pattern to continue through possibly the end of next week. A few spots here and there of rain and thawing returning to rain/snow mix or snow.

WeatherWatcher: Winter Storm Warning in effect until 11 AM Wednesday morning

Tuesday, November 29, 2022

 
Seattle City Light Outage Map at 10:40 PM PST

About 3778 City Light customers in Shoreline and Lake Forest Park are without power as of 10:40 PM PST. Shoreline Area News headquarters is now without internet because of the storm. Regular Shoreline Area News will resume once utilities are restored. The Echo Lake / North Ridge weather station is also offline as a result of a power outage.

The National Weather Service in Seattle at 10:24 PM PST has issued a Winter Storm Warning in effect for Seattle and vicinity which includes Shoreline and Lake Forest Park. An additional 3 inches of snow is possible overnight into Wednesday morning. The Winter Storm Warning expires at 11 AM Wednesday.

The Wind Advisory also continues to remain in effect until 7 AM Wednesday morning, gusty winds up to 45 mph are possible. More power outages are likely through the overnight hours into Wednesday morning.

As of 10:40 PM PST the cold front is moving south through Shoreline and Lake Forest Park. Heavy wet snow at times is expected as the cold front moves through. In the wake of the cold front a Puget Sound Convergence zone is expected to develop probably starting around Everett at first and then drifting south through Shoreline. 

The Convergence zone will produce mostly snow at these temperatures, locally heavy snow in spots. A warmup to rain or above freezing is still expected tomorrow afternoon but the warmup will be short lived. 

Another round of snow showers is possible into Wednesday evening with another inch or so of accumulation expected. Snow accumulations can locally total up to 6 inches by the end of the night Wednesday, even with the warmup in the afternoon.

It's going to be a rough week for winter weather, stay safe out there.

WeatherWatcher: Winter Weather Advisory issued 1pm Tuesday to 10am Wednesday

Monday, November 28, 2022

 
The kind of snow to expect in Shoreline Tuesday evening.
Photo by Carl Dinse

The National Weather Service in Seattle has issued a Winter Weather Advisory for the Greater Seattle area, which includes Shoreline and Lake Forest Park. The advisory is in effect from 1pm Tuesday afternoon until 10am Wednesday morning.

Snow should start flying sometime between 11am and 1pm Tuesday. 1 to 3 inches of snow is possible Tuesday evening into the late night hours.  Current forecasts for Shoreline call for the snow to change over to rain at around 11pm Tuesday night. However, there is a lot of uncertainty in the models, and snow could continue longer or change over to rain sooner. 

There is a winter storm watch in effect for our neighbors in the north for all of Snohomish County. 4 to 8 inches of snow is possible there before a change over to rain, especially on the higher hills.

As I mentioned in my last article, we are sitting on the margin of rain or snow all week. The type of storm coming in Tuesday afternoon is not a typical snow producer but due to all the cold air that is moving in overnight into Tuesday morning, it will start everything as snow. 

Strong south winds are expected with Tuesday's storm bringing ocean air into the area which in turn is expected to warm up temperatures for a while Wednesday morning and afternoon. Winds are expected to be gusting to around 35mph. 

Up to one inch of rain is expected during the warm period of the day. More cold air filters into the area Wednesday evening for a change back to a wintery mix as this storm leaves the area.

The high temperature on Tuesday is expected to be 35°F, late in the evening just before midnight. We will spend most of Tuesday below the freezing mark. The high temperature on Wednesday is expected to be 41°F, but only for about 2-3 hours.

Another potential snow maker is possible Friday morning, but I'm still watching how that forecast develops over the next couple of days.

WeatherWatcher: Snow level flirting with the lowlands all week

Clouds and precipitation over Puget Sound
Photo by Frank Kleyn

The photo is an impressive capture by Frank Kleyn of some convergence zone action over Puget Sound. At the north end of that cloud is a nice column of precipitation reaching the ground.

Cold and Snow potential:

Forecast models have been painting a picture since last Wednesday of the potential for several arctic waves to move through this coming week. There is still a lot of uncertainty, especially for mid- and late-week but expect the snow level to fluctuate between sea level and 1,000 feet all week. 

Plenty of showers are expected, as well as a cold front moving in through Tuesday night into Wednesday morning.

There is a winter weather advisory issued for western Snohomish county, including Woodway, Edmonds, Lynnwood and Everett. Shoreline might be snagged into a little of that fun as well. 

The winter advisory is in effect from 10pm Sunday evening until 10am Monday morning. Some snow showers are possible, and there could be some spotty accumulation of a dusting to an inch or so in some neighborhoods.

An active convergence zone is hanging out in Snohomish and north King counties overnight into Monday morning. Heavier showers could temporarily bring the snow level down to the surface and produce a small wet accumulation. Things should warm above freezing Monday as the sun rises and takes care of any frozen stuff left over.

Monday afternoon through Tuesday morning is expected to be mostly sunny and clear. Look for it to be breezy with winds gusting to 30mph and temperatures near 40°F for a high, and lows in the 20's. The next event arrives Tuesday afternoon into the evening, with winds increasing as the storm approaches.

Tuesday-Wednesday potential for snow:

Tuesday evening south winds are expected to increase, gusting to 30mph initially and increasing to 40mph late into Tuesday night. Rain or snow is likely with a snow level starting around 400 feet (most of the higher parts of Shoreline and Lake Forest Park). 

A few inches of snow accumulation are possible, but it's not certain with this event. Current high-resolution forecasts from the UW WRF GFS model show snowfall of around 4-6 inches in the Shoreline and Lake Forest Park area, but this is not accumulated on-the-ground snow. A lot of that snowfall will likely melt.

Wednesday it is expected that we warm up and transition to all rain for the day, but rain will taper off to showers, with winds still breezy through the day. Snow levels will still be hovering near 500 feet so it's marginal whether we will actually see snow on the ground.

Remainder of the week and into the weekend:

For Wednesday night through the weekend, the chance of rain or snow showers continues in the forecast. There are hints of another storm on Friday but for now they're backing off and calling it just showers likely. Thursday night into Friday could be our coldest window, with snow showers forecasted for Friday morning and a snow level at sea level.

Bottom line:

This is a week of uncertainty, and things could change rapidly. My best advice is to be prepared to deal with winter weather this week, especially before Tuesday evening. We could be dealing with the wintry mix weather for more than a week. A slight change in a storm track or strength could make all the difference in a big snow event or a mild rain event. 

Be sure to keep checking back on our webpage for updates in the forecast. I will try to keep my twitter feed updated as well on my weather station webpage if things change with short notice.

WeatherWatcher: Windy Sunday, a repeat of Thursday

Sunday, October 30, 2022

 

A frontal system very much like the one we just had on Thursday is moving in during the early morning through early afternoon hours on Sunday. It is expected to give us pretty much the same kind of breezy day, with winds gusting to 30-35mph, as we had on Thursday.

Another wind advisory has been issued by the National Weather Service for our neighbors to the north in Woodway and Edmonds up through Everett to the Canadian border. The wind advisory is in effect from 11PM PDT Saturday night until 2PM PDT Sunday afternoon.

Rain is expected most of the day Sunday, but it will be light for the daylight hours, with around a quarter of an inch expected. Once the front moves south in the evening, winds will slow a little and the rain will pick up with up to one inch of rain in the forecast for Sunday night.

For Halloween it will remain on the breezy side in the morning and afternoon hours with a chance of showers or showers likely through most of the day. It should be a little drier Monday evening for Trick or Treaters, with only a chance of showers remaining. 

Below is the UW WRF-GFS forecast model for Monday evening between 5pm - 8pm PDT. It appears Shoreline and Lake Forest Park will fall in the Olympic Mountain rain shadow at this time so it should be mostly dry. It does however show a convergence zone near Everett. Convergence zones are very difficult to forecast even hours before they form, which means it's possible that convergence zone may develop further south into the Shoreline and Lake Forest Park areas.

Cloudy and wet weather is expected through the remainder of next week with near normal temperatures. We might see some sun breaks on Wednesday. Thursday evening through the next weekend has a steady rain signal in the forecast.

WeatherWatcher: Windy day on Thursday, more rain on the way

Wednesday, October 26, 2022


The National Weather Service in Seattle has issued a wind advisory to our neighbors in Woodway, Edmonds and northward. Areas along the water are expected to see the strongest winds and I imagine the neighborhoods near the water in Shoreline such as Richmond Beach will get in on the action as well. Most of Shoreline will feel these winds but not quite into Wind advisory criteria, according to forecasts.

Winds are expected to gust up to 35-40mph Thursday between 5am and 8pm PDT. I think it's possible we could see a stray gust of 45-50mph near the water or in the extreme north end of Shoreline and Lake Forest Park. Some scattered power outages are possible, any light objects left loose in a yard could get blown around as well.

Thursday evening, as the winds die down, more rain arrives. Somewhere around a quarter to a half inch of rain is expected with the passing cold front. Rain is expected to continue through most of Friday before tapering off in the evening.

Saturday is probably our better of the two days this weekend with only a chance of showers among cloudy skies. Another rainmaker comes in to keep Sunday rainy all day. Rain is expected through the beginning of next week as well at least through Wednesday.

Rainfall by the numbers: we haven't caught up yet to normal for October, but we've made up almost a third of it in just a few days.

Temperatures are back down to normal now too, both in the daily high temperatures and daily low temperatures.

The switch to fall weather has occurred.

WeatherWatcher: Fall rains arrive Friday, unwelcome smoke to clear out

Thursday, October 20, 2022


The switch is flipping. Autumn is now turned on and this unwelcome wildfire smoke will soon become history. Half an inch to 1 and a half inches of rain is expected to fall between Friday morning and Sunday evening. Most of the rain will be Friday into Saturday.

Roads will be very slick especially on Friday due to the buildup of oils with this very long dry streak we had. Take extra caution during the commutes Friday with these slick roads, it might feel like driving on ice.

Sunday might be our nicest day this weekend with a break in the rain during Sunday morning and afternoon. More rain returns Sunday evening and continues into Monday next week. Steady rain or a chance of rain remains in the forecast all the way through next week. 

Mountains will see snow come down to Stevens Pass level as well. US 2 will be potentially hazardous through the weekend. Debris flows or mudslides are possible along the areas burned by the Bolt Creek fire, and snow will make its first appearance at the summit.

This string of much overdue weather should put an end to our wildfire season.

82º in Shoreline Sunday - 88º in SeaTac

Sunday, October 16, 2022

Multiple smoke plumes from old and new wildfires in the mountains impacting air quality.

82°F was our high temperature today, both at Northridge in central Shoreline and Richmond Beach in west Shoreline. 

At 7pm it was obvious that our onshore flow had returned, as Richmond Beach was 7 degrees cooler than the Northridge station, 76°F vs 69°F. By 9:30pm it was down to 60°F in Northridge and 59°F in Richmond Beach.

October 2022 high and low daily temperatures.
With the onshore flow returning, air quality is now starting to improve with most areas down to the moderate level on the AQI index.

SeaTac's preliminary high temperature of 88°F shatters the record. The old record for the day was 72°F. This is by far the latest in the year it has ever been recorded as that warm. The all-time October high temperature record is 89°F, set on October 1, 1987.

WeatherWatcher: Air Quality Alert, Rain finally in distant sight

Saturday, October 15, 2022

 

Smoke filtered sun

The summer that keeps on giving and should have ended a month ago continues. We have had no measurable precipitation for the entire month of October thus far, and we are far above the average temperature for this time of year. 

There is an end in sight, though and much needed rains are appearing on the horizon. We must get through this weekend and next week first.

October temperatures compared to average in Shoreline (Echo Lake/North Ridge station)

An Air Quality Alert is in effect through the weekend. Offshore flow is expected to increase during the weekend, bringing us warmer and drier air and smoke from the Bolt Creek Fire. Winds in the mountains will be increasing from the east as well, which will fan the wildfires and increase their activity.

Forecast calls for sunny skies and areas of smoke. Temperatures Saturday are expected to be in the 70's and Sunday we could see temps near 80°F. Onshore flow (westerly winds) returns Sunday evening which will cool us back down and hopefully clear some of the smoke out.

Monday through Thursday next week is expected to have continued sunny skies with temperatures in the mid 60's to near 70°F. Not much of a change day to day until we get to around Friday. The jet stream begins to drop south, aiming the river of storms and cold fronts to our region.

Long range suggests we'll switch to more normal October weather overnight Friday and continue, as far as models can go. Accuracy is highly degraded though when going that far out in forecasting. One thing is for sure, we are heading into our third La Niña winter season in a row, which means more rain and colder than normal temperatures in general.

Winter season outlook: With the Pacific Decadal Oscillation (PDO) deep into a cold phase and a triple dip La Niña, we can expect this winter to be on the cold and rainier side of things, not unlike the past few winter seasons we've had. Usual frequency of storms is expected with probably at least one significant snow event. 

I do expect Shoreline and Lake Forest Park to be snowier than average again this winter. Keep in mind the official average annual snowfall for Seattle is around 4.6-6.3 inches. I expect we will see more than 6 inches of snow this winter through one or multiple events.

If the smoke doesn't get too unhealthy this is probably the last weekend to do outside stuff before the rains finally return. I'll be checking air quality on the Puget Sound Clean Air agency website to determine if it's safe to do any outdoor stuff this weekend. Summer is finally coming to an end.

Red Flag Warning in effect until Midnight Saturday night.

Air Quality Alert in effect until 6pm Sunday.

A Red Flag Warning has been issued by the National Weather Service in Seattle. A Red Flag Warning means that critical fire weather conditions are either imminent or occurring now. Any fires that develop will likely spread quickly. Outdoor burning is not recommended.

Winds are northeast 10 to 15 mph with gusts to 30 mph. Relative humidity is low; some places may get as low as 20% or less. Temperatures are in the lower 70's, we could reach temperatures into the 80's on Saturday.

Air Quality:

The brown plumes streaking westward from the Cascade mountain range is wildfire smoke.
Satellite image from the National Weather Service on Friday September 9, 2022.

The Puget Sound Clean Air Agency and Northwest Clean Air Agency have issued a joint air quality alert in effect from 6am Saturday to 6pm Sunday. The air quality is expected to become unhealthy for sensitive groups. All sensitive groups should limit spending any time outdoors. People with health conditions may have worsened symptoms. Healthy people may start to have symptoms.

Wildfire smoke can cause burning eyes, sore throat, headache, coughing, wheezing, shortness of breath, and worsening of heart and lung conditions. 

Forecast: Hazy sunny skies through the weekend, with highs near 80°F both Saturday and Sunday with lows in the upper 50's. On-shore winds pick up Sunday afternoon and evening, which should begin to cool temperatures down and start pushing the wildfire smoke back into the mountains.

Monday a weak weather system is expected to bring a slight chance of showers with some clouds in the morning, clearing to mostly sunny skies in the afternoon and evening. Tuesday through next weekend should be pleasant, with sunny skies and highs in the low to mid 70's all week. Lows in the mid 50's all week. A slight chance of showers might return at the end of the work week.

WeatherWatcher: Excessive Heat Warning extended until Sunday night

Saturday, July 30, 2022

A sunny day at the Edmonds Beach
Photo by Lee Lageschulte
The National Weather Service in Seattle has extended the excessive heat warning through 9pm Sunday night. High temperatures are expected to continue into the upper 80's through Sunday. Shoreline is sliding into the cooler side of the heat wave now so we should be getting a little bit of relief this weekend.

Here's what the forecast models are expecting high temperatures to be at the Echo Lake/North Ridge weather station this weekend:

Saturday: 89-90°F
Sunday: 85°F

Want cooler temperatures? Head toward Puget Sound. The Richmond Beach neighborhood has been consistently topping out at around 4-6°F cooler than most areas in Shoreline and Lake Forest Park.

High and low temperatures for July 2022 compared to average
at Shoreline Weather's Echo Lake station.

Here are the high and low temperatures at both stations this week:


Forecast after the weekend calls for cooler weather, with drizzle or rain showers possible Monday. 

Temperatures will come down into the 70's for highs and lows will be in the upper 50's. Thunderstorms are possible over the mountains so it's possible we might be treated to a lightning show sometime next week. 

A slight chance of showers and partly cloudy skies looks likely to stick with us through all next week.

WeatherWatcher: Heat Watch in effect for Tuesday afternoon through Friday evening

Sunday, July 24, 2022

 

National Weather Service in Seattle

Right on schedule, a heat wave is coming to the area this week. The end of July and beginning of August is typically the hottest time of the year, often with heat waves bringing temperatures into the mid 80's to mid 90s. This year is no different as the forecast is calling for high temperatures in the 90's between Tuesday and Friday.

The National Weather Service in Seattle has issued an excessive heat watch, in effect from Tuesday afternoon through Friday evening. This watch will likely turn into an advisory by Monday evening. 

  • Temperatures on Monday are expected to creep into the mid 80's. 
  • Tuesday through Friday we are expecting high temperatures in the upper 80's to low 90's. 
  • Wednesday and Thursday are expected to be the hottest, with temperatures possibly reaching the mid 90's. 

Low temperatures through the week are expected to be down only to the mid to upper 60's. Areas closer to the Puget Sound such as lower parts of Richmond Beach and Innis Arden will likely be a few degrees cooler especially during the hottest part of the day.

Next weekend we cool down a little bit, but we are still expected to get into the 80's both days. I think it's safe to say that summer has finally arrived. We'll all quickly miss that colder and wetter than normal weather pattern we've had for the past 4 months.

WeatherWatcher: Heat Advisory issued 12pm Saturday to 11pm Monday

Saturday, June 25, 2022

 

National Weather Service in Seattle

The National Weather Service in Seattle has issued a Heat Advisory for the greater Seattle area including the cities of Shoreline and Lake Forest Park. The heat advisory is in effect from Noon Saturday through 11pm Monday night.

From the National Weather Service:
  • What: Hot conditions with high temperatures in the mid to upper 80s on Saturday, and low 90s on Sunday and Monday. Overnight low temperatures will likely only cool into the low 60s for many locations Saturday night and again Sunday night. This will pose a moderate risk of heat-related illness.
  • Where: Portions of northwest and west central Washington.
  • When: From noon Saturday to 11 PM PDT Monday. 
  • Impacts: Hot conditions will increase the risk of heat- related illnesses for those who are sensitive to heat, especially those without effective cooling or adequate hydration. 
  • Additional Details: A significant increase in cold- and high- water related incidents is possible. Recent rains and late snowmelt has lead to high, fast and cold flows on area waterways. Cold water shock can lead to life-threatening hypothermia within minutes. Use extreme caution if recreating near water, wear a life jacket, and supervise children closely.  
Forecast: Sunny and clear skies between Friday night and Tuesday morning. Lows near 60, highs into the mid 80's. On Monday the high temperature will reach into the neighborhood of 90°F. Winds are expected to be gusty as well, with north winds gusting between 30-35mph through the weekend and on Monday.

Tuesday morning we cool back down with highs in the lower to mid 70's and partly sunny skies with a chance of showers. Wednesday is a repeat of Tuesday, with clearing returning on Thursday to end the week with sunny skies and highs in the mid 70's.

WeatherWatcher: Scattered thunderstorms threat returns on Sunday, and La Niña

Sunday, June 5, 2022

Convective clouds and thunderstorms on Friday June 3, 2022.

A brush with thunderstorms on Thursday and then a direct hit of thunderstorms waking us up Friday morning led to a lot of dramatic looking skies to end our week. The threat of even more thunderstorms returns on Sunday and Sunday evening. 

When thunder roars go indoors.

Showers continue Monday, then on Tuesday we will get a break and it might seem like a mid-April day, with sunny skies and high temperatures into the low 70's. Clouds and showers return Thursday into the next weekend. Next Friday although is a long stretch as far as forecasts go, and looks to be the wettest day of the week.

Temperatures are warmer than they have been, finally. We should be breaking the 60 degree mark every day next week, three out of the next six days could break 70°F, despite the clouds and rain showers. You can blame all this cool and wet weather on La Niña, which is continuing strong into its third season in a row.
 
The current ENSO forecast calls for likely continued La Niña conditions through summer and at least next fall/winter. This is being called a triple dip La Niña; they are rare, but not unheard of. We've had several events in the past 50 years where there were three La Niña years in a row.

What does this mean for our local weather? More of the same, colder than average, wetter than average here in Shoreline and Lake Forest Park. 

Summer should be somewhat of a relief from last year, with hopefully no major heat waves. We can't rule them out completely but we likely will be cooler this summer as a general average than we have been for a few years. 

Fewer days in the 80's, a lot fewer days breaking 90°F, and 100°F is unlikely. More thunderstorms are possible, more rain events and clouds.

The winter that is never ending, a winter storm is moving in Wednesday morning. Power outages are possible as we are late enough in the season that most of our trees are now fully leafed out. Rain comes first in the morning, with increasing winds in the afternoon with gusts up to 40mph possible.

We are expecting around a quarter inch of rain Wednesday, mostly early in the morning, tapering off to scattered showers late morning and afternoon. High temperatures are expected to be in the upper 50's or low 60's. Winds are expected to calm down late in the evening towards midnight.

Thursday morning brings another round of rain with highs near 60°F, lows in the upper 40's. Friday through the weekend almost looks nice relative to our recent weather. Sunny skies and highs in the mid to upper 60's. Slight chance of showers returns to end the weekend on Sunday afternoon and evening.
