WeatherWatcher: High Wind Advisory issued

Tuesday, December 31, 2019

Shoreline after a windstorm August 29, 2015
Photo by Carl Dinse


The National Weather Service in Seattle has issued a wind advisory for the greater Seattle area including the cities of Shoreline and Lake Forest Park. This is our first advisory or warning of any kind issued this 2019-2020 storm season.

Wind Advisory in effect from 10am Tuesday to 4am PST Wednesday.

  • Southeast winds of 20 to 35mph with gusts to 45mph expected.
  • Winds are expected to be strongest between 9pm and 2am.
  • Impacts: Gusty winds could blow around unsecured objects. Tree limbs could be blown down and a few power outages are possible.

Rain: We are expecting several decent doses of rain starting with one dose on Tuesday bringing us a quarter to a half inch of rain. Tuesday night into Wednesday morning we have break in the steady rain but there's a slight chance of a thunderstorm during that break. If we do see a thunderstorm we could see heavier rainfall. The timing of the thunderstorm chance is between around 10pm Tuesday night, along with the winds, until around mid-morning Wednesday.

Our next dose of rain comes in Wednesday afternoon with another quarter to a half inch of rain possible. We'll get a short break Thursday morning and then our next wet system moves in.

Thursday's storm is expected to last through Saturday afternoon, and more winds are possible with that system as well. I'll be able to have a better idea on those winds when we get closer to Thursday.

WeatherWatcher: From the archives - Christmas Day Wind 2011, and Today's forecast

Thursday, December 26, 2019

Carport damaged by fallen tree in the Echo Lake Neighborhood, December 25, 2011
Photo by Carl Dinse


This week from the archives I bring to you a Christmas Day windstorm. Eight years ago a forecasted but stronger than expected windstorm blew through Shoreline and Lake Forest Park right about noon on Christmas Day. Winds were recorded gusting in the Shoreline area around 40mph, but other exposed areas in the region saw gusts as high as 60mph.

In one corner of the Echo Lake Neighborhood not far from the Northridge/Echo Lake Shoreline weather station a tree came crashing down onto a carport. The vehicle parked under the carport appeared to be spared from any damage; the carport did its job.

I was doing weather reports even then for Shoreline Area News. You can find my original article on the storm, and the forecast that week here: WeatherWatcher: Christmas Day storm signals end of dry spell. We also had a follow-up article: Stories from the Christmas Day wind storm.

Today's Forecast: Don't be surprised if you see some light snow or snow mixed with rain late Thursday night or early Friday morning. It's marginal and just cold enough to produce the wintery mix but the weather system bringing the moisture is warm. We should warm up Friday morning into the low 40's with rain changing over to showers in the afternoon.

Saturday brings chances of rain, with increasing steady rain Saturday night and rain on Sunday. We get a slight break on Monday with mostly sunny skies before our next rainy weather system moves in Tuesday lasting through New Year's morning.

Longer range: Looking at a mostly wet and seasonable pattern for the first few days of the new year, but further out looks like we might run colder than normal. There's even some early hints we might see our first accumulating snow event of the season before the middle of January. The uncertainty of forecasts that far ahead, however is really high. Forecasts struggle with snow of any amount here even if it's as close as 6 hours away. It's probably a good idea to get ready for snow in the next two weeks, just in case.

WeatherWatcher: Moderate Atmospheric River is over

Saturday, December 21, 2019


File photo by DKH

Our atmospheric river event has ended, bringing us a 3-day storm total of 3.86 inches of rain. Areas south of downtown Seattle received over 5 inches of rain. We were somewhat protected from the brunt of this system by the Olympic mountain rain shadow. With this weather system December has now made it to about average for total rainfall in the month.

Rainfall compared to average at the North Ridge / Echo Lake weather station.

This kind of rain is actually typical in the area every couple of years. We had a lot of these systems during the winters of the 1990s. They are so numerous that I am not able to easily go back and pick out the last time it rained more than this in the past five years. The last wet weather system or series of events we had that stands out to me is October 27 - November 1, 2012. During that five day stretch we had 7.19 inches of rain collected in the North Ridge / Echo Lake weather station.

Sea-Tac airport, which is the official record keeping station for the Seattle area, had their wettest three day stretch since April 5, 1991. December 20, 2019 was Sea-Tac's wettest day since November 6, 2006, and beat out February 8, 1996 as the next wettest day.

The Forecast is somewhat uncertain for the next week. Colder air is moving in but there still is uncertainty as to how cold it might get, and what moisture might be around. Right now it appears we will be warm enough for any moisture to fall as rain. We are expecting temperatures to range between a high in the low 40's and lows in the mid to upper 30's.

Sunday through Monday we are looking at cloudy skies, with a chance of rain. Monday night the clouds move out to a mostly clear night, with sunny skies on Tuesday. Tuesday night clouds move back in with a chance of rain into Christmas morning.

There's a very slight chance that rain on Christmas morning could have some snow flakes mixed in early in the morning. The rest of the holiday is expected to be mostly cloudy with a slight chance of rain into the evening.

Thursday through next weekend there is a slight chance or chance of rain on and off, with mostly cloudy skies. We might have a break in the clouds during the day on Thursday.

WeatherWatcher: Big change to rain and wind on the way

Thursday, December 19, 2019

Heavy Rains in Lake Forest Park
October 10, 2015
Photo by Carl Dinse


A major weather pattern change is occurring Wednesday night and Thursday morning. An atmospheric river, better known as a Pineapple Express, is heading our way. This is looking like the most significant surge of rainfall we've had in a couple of years.

Light rain is falling in the area Wednesday night and Thursday morning. We may see a short break before the main events start moving in Thursday afternoon through Saturday evening.

Winds are expected to pick up as well, with gusts as high as 40 mph possible Thursday night into Friday.

Rains continue Friday, Friday night, Saturday, Saturday night, with the rain breaking up into showers late Saturday night or Sunday morning.

Total precipitation values by Sunday could be between 1.75 inches and 4 inches of rain, possibly more. Our average total monthly rainfall for December is 5.15 inches of rain so this is a pretty big event.

This is not exactly unusual, as these were common events in the late 90s and early 2000s. We've typically seen at least 1-2 of these events in any given winter season. Some years they produce several inches of rainfall, other years only about 1-2 inches of rainfall.

We start drying out Sunday through Christmas day, with just a chance of showers here and there. A white Christmas is not likely this year. Temperatures will be near 50°F for a high until Saturday, where we cool down to the mid-upper 40s for a high temperature. Lows will start creeping from the low 40s into the mid 30s again once we get through Saturday as well and into next week.

Today in historic weather: 29 years ago, on December 18, 1990, we had a strong arctic front with a convergence zone move through the area at about lunch time. This event was never forecasted, and was a complete surprise for the region. It brought over 8 inches of snow in about 30 minutes. Later in the evening thunder snow moved through Shoreline and power was out in many neighborhoods with strong north winds gusting over 40 mph.

When all was said and done around 12 inches of snow had fallen in the area and temperatures plummeted to the low 20's and upper teens. The snow and cold lasted well past Christmas Day that year, with another arctic blast hitting the region before New Year's.

WeatherWatcher: Flurries possible, then we warm up

Saturday, November 30, 2019

Dusting in Shoreline in 2010
Photo by Carl Dinse

There's been more talk of snow in the forecast for late Saturday evening and Sunday morning. This particular event is weak, offshore and is a bit too far south. In addition to the distant location of this weather system it also has a mild southwest flow off the Pacific ocean so it may warm the air up too quickly for anything but a couple of sprinkles.

There's a lot of cold and very dry air in place right now over the region. Most of the precipitation in this weather system will likely evaporate before it reaches the ground. At this time, for most areas north of Tacoma we are looking at a very slight chance of any precipitation. This means the chance of any rain or snow falling from the sky is very slim.

Bottom line: Our most likely scenario is just a dry, cloudy day with gradual warming by afternoon. In current forecast models there's a very slim chance that we will see some snow flakes falling from the sky Sunday morning. These forecasts often have a lot of uncertainty in them. There could be about a 0.05% chance of accumulating snow of about an inch. In the end though, this will be short lived in any case as we will get into the low-mid 40's by Sunday afternoon. Very small chances of rain remain in the forecast into Sunday evening.

Remainder of next week: We clear up again on Monday with sunny skies and high temperatures near 45°F, a clear Monday evening with lows dropping into the mid 30's. Tuesday clouds return with a slight chance of rain. For Tuesday evening through next Friday we maintain a chance of rain with high temperatures in the mid-upper 40's, and low temperatures in the mid-upper 30's.

November has been one of the driest Novembers on record. In Shoreline we average 6.63 inches of rain in November. This year we are at 1.34 inches of rain. We also averaged 1°F above average for the month, even with our current cold snap. There are some hints in longer range forecasts that we may start seeing a more typical, active weather pattern starting late next week or next weekend.

WeatherWatcher: Saturday night wind, very slight chance of some snow flakes

Sunday, November 24, 2019

Marginal snow in Shoreline
Photo by Carl Dinse

Saturday night wind: We had a forecast for a breezy Saturday night, but it turned into a typical fall windstorm. Amazingly there were not very many power outages with the wind. We saw wind gusts at Richmond Beach to 37mph around 11:30pm Saturday night. A station in Kenmore right on the lake recorded a wind gust of 47mph. Rainfall was not nearly as much as forecasted either; at most we received 0.05 inches of rain.

Forecast: A lot of talk about snow has been in many forecasts for the past 3-4 days. Bottom line, I don't think we are going to see any accumulations within the next 5 days. There is a strong low pressure system moving inland to our south. The low pressure system is expected to make landfall around southern Oregon or Northern California. This is several hundred miles too far south to really produce any snowfall in our area. Cold air also isn't quite cold enough in Canada yet to put us in a good freeze. Both are ingredients typically required to generate a good lowland snow event here.

What is expected for Shoreline and Lake Forest Park is a couple of hit or miss rain showers Monday. Colder air is flowing into the area from Canada, so Monday night temperatures are expected to start dropping. As the cold air moves in, the moisture moves south. There is a very narrow window around 3-7am with a slight chance of a shower, and with it maybe some snow flakes mixed in. We might see a dusting on lawns before it quickly melts away, but it is much more likely we will just have some cold, light, rain showers.

We dry out Tuesday afternoon and into the holiday weekend. Sunny skies and clear cold nights are expected, with lows in the 20's and highs in the upper 30's or near 40°F. Thanksgiving Day is expected to be our coldest day with a high temperature near 37°F.

The next threat of activity is Sunday, where we might see rain showers start as a rain/snow mix. At this time that's too far in the future for weather forecasting and there is no real certainty to the forecast for Sunday yet. I will provide updates if anything changes.

WeatherWatcher: One clap wonder strikes near home, up next: Wind

Saturday, November 16, 2019

Lightning during a summer storm on Lake Washington from Log Boom Park.
Photo by Carl Dinse

Were you in the area about 10 minutes after 5 PM Friday evening? If so, you probably didn't miss that very loud, ground shaking thunderclap we had.

Mother nature is making up for two weeks of uneventful weather.

A strong Puget Sound Convergence zone developed Friday evening behind the morning's cold front and light rain. The convergence zone crept its way south from Everett to Shoreline and east. This band was so strong, it created a weak rotation within a thunder cell just north of Shoreline and Lake Forest Park.

Storm cell rotation is usually the warning that a tornado may develop, but in the Puget Sound region tornados are extremely rare, so rotation in a cell is just a sign that we have an unusually strong thunderstorm on our hands.

Around 4:46pm the power flickered as the first cloud-to-ground lightning bolt struck on the western edge of the Snohomish river valley in Everett. 

The power surge from that lightning strike was reported in Everett, Seattle, Shoreline, and Mukilteo. I think it's a safe assumption that was because the lightning struck one of the main power transmission towers crossing the Snohomish river valley into Everett before feeding down towards Seattle.

Then as the Puget Sound Convergence Zone drifted south, at just before 5:10pm a powerful cloud-to-ground-lightning bolt struck right near Interstate 5 and the 220th St SW interchange in Mountlake Terrace.

Area circled in red is the approximate location of the 5:10pm lightning strike.

The lightning strike was really brief, but so powerful it sounded like an explosion followed by a long rumble. The thunder shook buildings through Shoreline and all the way up to Everett. The Shoreline Community Collage seismograph even detected shaking from the thunder at 5:10pm.

To give you an idea what this convergence zone looked like this evening, below are two screen shots of the Doppler radar at the time. First image is the radar for 4:45pm, second image is the radar from 5:15pm.

Radar at 4:45pm

Radar at 5:15pm

Most of the rain from this event stayed north of the county border. Areas in Bothell and east received over an inch of rain in less than one hour. The rain gauge at the Shoreline Richmond Beach weather station didn't have any measurable precipitation, whereas our Shoreline Northridge (Echo Lake) weather station saw 0.01 inches from this event.

Next on the horizon, a new storm is making its way into our region on Saturday. There will be a chance of light rain Saturday afternoon, with winds expected to pick up Saturday evening. This isn't a major wind storm, but there will be strong breezes gusting possibly up to 30-40mph.

Winds taper off Sunday morning, with a relatively calm Sunday afternoon and evening. We have another rainmaker moving in on Monday. Extended forecast after Monday calls for a calmer Tuesday, still breezy but with showers. Wednesday through next Friday, however, looks sunny, clear, chilly and breezy at times. Highs near 50°F with lows in the mid-upper 30's later in the week.

WeatherWatcher: Winter outlook and this week's forecast

Sunday, October 20, 2019

Winter day on NE 185th St I-5 overpass
Photo by Carl Dinse

I've been seeing a lot of headlines and getting a lot of questions about what this winter might hold in store for us. So it's that time again when I tell everyone what I think might happen this winter, and scare you with all the possibilities.

Today, we seem to be lining up pretty close to the 1967-68 winter. The mid season snowfall last February and coming off an El Niño winter with a near neutral PDO index (Pacific Decadal Oscillation) lines right up with the 1967-68 time frame. That winter had a couple of snow events, around 3-4" in December and about 8" of snow in January. 

The Pacific Decadal Oscillation (PDO) index is near neutral, slightly in the cool phase. We had a warm blob off the west coast that has been dissipating, and the Pacific ocean seems to be configuring itself for a cool phase. The PDO is a fairly recently discovered oscillation and a method of forecasting it is not well developed. So right now it's hard to say if the PDO is going to go into a full cold phase, or remain neutral or otherwise. Cool phases of the PDO typically, but not always, have influenced more lowland snow events and arctic outbreaks for the area.

The El Niño Southern Oscillation is in a neutral phase, and expected to remain that way through the 2019-2020 winter. That means, no El Niño, and no La Niña, so there's no cooler and wetter or warmer and drier influence there. Neutral years tend to be more stormy and more variable than an El Niño or La Niña.

The upper atmosphere jet stream has been favoring the same patterns as last February, which is why we've been cooler than normal much of the last 45 days. I think we should expect to see this intermittent blocking and trough pattern throughout the winter season.

What does this mean for our winter? Stormy periods, warm periods, cool periods, a couple of lowland snow events, and a fair share of windstorms. It's likely we will see our first taste of lowland snow near Thanksgiving. I'm feeling we have a solid 50% chance of another prolonged arctic outbreak sometime this winter as well, complete with a solid snow cover. I also think we could see a couple atmospheric river events, with more rainfall than the ones we've been seeing the past 5 years or so.

So, a lot of this:

A few of these:

One or two of these:

Finally a 50% chance of this:

Between now and the first week of November is probably a good time to get yourself prepared for winter storms. 

Bottom line: We are not likely to have a mild or calm winter.

This week's Forecast: We have a stormy start, but a calm ending to this week's weather forecast. 

Monday is going to likely be another breezy and wet day. Monday evening may see some pretty good wind gusts up to 35mph, not quite strong enough to reach high wind criteria. Rainfall amounts for Monday could be significant; up to 1-2 inches of rain is possible. High near 57°F, a low near 50°F.

Temperatures Tuesday through the weekend vary between the upper 50's to right around 60°F. Lows in the mid to upper 40's to around 50°F. Showers Tuesday, Thursday night, Friday, and Saturday. Partly to mostly sunny skies Wednesday-Sunday. Yes, the forecast calls for partly sunny skies, and a chance of showers on some of these days later in the week.

WeatherWatcher: Forecast Update: Slight chance of thunderstorms Thursday

Thursday, October 3, 2019

Photo by Carl Dinse
There's been a slight change in the forecast for the upcoming storm arriving Wednesday evening into Thursday morning. A chance of rain increases as the morning progresses on Thursday. We are expecting to see some breezy conditions as well.

South winds of 10-20mph, switching to southwest winds of 15-25mph in the afternoon.

Something else we are starting to become familiar with is possible as well. There is a slight chance of some isolated thunderstorms in the area Thursday afternoon and Thursday evening. Possibly a repeat of last Friday September 27.

Friday and Saturday the chance of showers remains in the forecast; however, we may have some sun breaks on Friday.

Sunday and Monday look to be mostly dry, before another weather system returns late Monday evening or Tuesday morning.

Temperatures for the next 5 days are looking to be fairly consistent, lows in the mid-upper 40's with highs near 60°F.

WeatherWatcher: Lightning and Thunder return to the skies again

Sunday, September 29, 2019

Convergence zone clouds over Shoreline.
Photo by Jan Hansen

Lightning and thunder returned to our skies for a third time this month on Friday, September 27, 2019. The atmosphere above us has been cooling rapidly over the past few weeks. This is due to an upper level jet stream pattern that has locked in place bringing us arctic air. If the upper level pattern continues to favor this configuration we may be in for a stormy and snowy winter.

Friday's storm was actually the result of a classic Puget Sound Convergence Zone event. We had cold air moving out of the Frasier river canyon from interior British Columbia colliding with mild moist air moving in from the southwest.

Here's the radar image at 5:30pm on Friday showing the developing convergence zone. The nice arc shape is actually the wave of colder air pushing south, creating the strong convection and precipitation band.

Radar image by the National Weather Service

Here's the image at 6:30pm as the lightning approached the Shoreline and Lake Forest Park area. You can see how the precipitation band is now well into downtown Seattle near Elliot Bay.

Radar image by the National Weather Service

Some of the more intense showers had some hail, as well, that briefly accumulated in lawns and on decks.

Forecast: This week should be relatively calm, but much cooler than we are used to. We're going to start the week with mostly sunny skies and clear nights, lows in the 30's, highs into the upper 50's. We may see our first frost this week. 

The sunny skies start to fade Wednesday afternoon with increasing clouds and a slight chance of rain Wednesday night. Thursday through the weekend we warm up a bit to lows in the 40's, highs near 60, and a chance of rain for the entire period.

WeatherWatcher: Blustery day Tuesday as fall weather pattern continues

Monday, September 16, 2019

Breezy waters in Shoreline
Photo by Carl Dinse


Our fall-like weather pattern is expected to continue this week. We have the strongest storm we've seen since last spring rolling through on Tuesday. We could see up to half an inch of rain with this new storm, as well as breezy conditions.

Winds could get as strong as 25mph, maybe even 35mph in spots. Also, there's a slight chance of a thunderstorm in the afternoon or evening, but the chance is pretty slim north of Seattle.

Wednesday brings showers, with another threat of isolated thunderstorms in the afternoon. Thursday may be our dry day with partly sunny skies with a high temperature in the upper 60's. Showers return Thursday night through Friday night.

For the weekend and beyond, Saturday is another potential dry day with rain returning Saturday night and into Sunday. We are expected to continue with the showery weather pattern into the early part of next week as well.

Temperatures all week long are expected to range in or around the mid 60's for high temperatures with lows into the mid-upper 50's.

WeatherWatcher: Rare summer thunderstorm, this week's forecast

Sunday, September 8, 2019

Lightning striking the Puget Sound September 7, 2019.
Photo by Wayne Pridemore

We had a rare and very active summer thunderstorm hit the region Saturday evening starting at about 8pm and ending sometime by midnight. For the entire region the National Weather Service counted about 2,171 cloud to ground lightning strikes, averaging about 7-8 lightning strikes per minute. 224 of those strikes in King County and 449 of those strikes to our north in Snohomish County.

Here's the radar image during the peak of the storm over Shoreline and Lake Forest Park. Yellows and reds are heavy showers, some containing hail. The heavy precipitation was short lived, with the Richmond Beach station picking up 0.21 inches of rain from this storm system. It doesn't seem like much, but nearly all of that fell within an hour, where a typical winter day might bring a half inch of rain over a 24 hour period.

Radar by the National Weather Service in Seattle

Forecast models actually had this storm system well forecasted by 5am Saturday morning. Professor Cliff Mass at the University of Washington did a good write up about the forecast and details of this storm here.

Forecast:

Forecast by the National Weather Service in Seattle

The slight threat of lightning remains in the forecast for Monday between 11am and about 8pm. Apart from that, showers are expected with a high temperature near 66°F. Monday evening we have a rain storm moving in after 8pm with steady rain expected overnight into Tuesday. Rain is expected to taper off Tuesday morning with clouds eventually breaking into mostly sunny skies.

Tuesday evening through Thursday evening the threat of showers remains in the forecast but this will likely be our driest and warmest portion of the week. Cooler weather returns Friday with again a renewed slight chance of a thunderstorm with the rain showers.

Next weekend and beyond we are looking at cool and showery weather, with our next dry spell starting possibly next Monday and lasting nearly a week, but at this point we're getting into longer range forecasts.

WeatherWatcher: Mild, short heat wave

Tuesday, August 27, 2019

Sunny skies in Shoreline, Washington
Photo by Carl Dinse

Warm weather is returning for Tuesday and Wednesday this week. There has been a lot of reporting about it being really hot, but most of the forecast models for the last day or two have backed off for those of us who spend our time north of downtown Seattle.

In general, most forecast models are pointing to high temperatures in the low 80's on Tuesday and Wednesday. We have a marine air push arriving Wednesday evening that will cool us back down into the 70's for the rest of the week and through the weekend.

The source of our warm air on Tuesday and Wednesday? The easterly and northerly winds will be picking up, bringing warm air over the mountain ranges from the interior of British Columbia and Eastern Washington. Tuesday is expected to be particularly breezy with north winds gusting up to 25mph, maybe even 35mph in some spots.

I took screenshots of the UW WRF (University of Washington Weather Research and Forecasting) GFS models of Western Washington for Tuesday and Wednesday at 5pm.

Tuesday:

Wednesday:


Temperatures in this model are in degrees C, and the shade of color on both days falls in the range of 24°C - 25.5°C, if I'm reading that right, so between 75°F and 78°F for our area. A slightly warmer spot along the Puget Sound coast for Shoreline of up to 27°C or 81°F.

Bottom line: With the changes and disagreement in forecast models the past few days I think we could see it go either way, staying in the upper 70's or possibly reaching the mid 80's until Thursday. Most likely I think we'll see around 84°F Tuesday, and 80-82°F Wednesday. I will keep an eye on the difference between Northridge and Richmond Beach weather stations to see if that little heat bubble develops near the Puget Sound coastline on Wednesday.

If you want really warm weather, I hear Portland will reach the upper 90's for the next two days.

WeatherWatcher: Unusually blustery weather for Friday

Friday, August 2, 2019

Unusual weather for August is heading our way overnight into Friday morning. We have a cold front that looks more like October, already on the coast moving inland with steady rain. Along with the rain, we are also expecting unusually breezy conditions for August.

There is a little bit of a difference in model forecasts for winds as shown in the two graphics below. I'm leaning more towards the National Weather Service forecasts, but there could be a stray gust that is stronger than 25mph.

Here are the expected wind gusts for Friday by the National Weather Service:

Image
Graphic by National Weather Service

The National Weather Service is forecasting winds of 20-25mph for our local area.

The University of Washington WRF (Weather Research and Forecasting) 4km model is forecasting wind gusts up to 25-30 knots, or 30-35mph.


UW Weather Research and Forecasting model is forecasting 25-30 knots,
Graphics by University of Washington

With trees in full summer foliage, it is remotely possible with these winds to have some tree limbs break off, and maybe even a local power outage. Winds are expected to be fairly breezy from about 4am until around 4pm, with the peak between 10-11am. 

Rainfall amounts will be fairly light, enough to get everything wet, but not major. You'll still probably need to water those thirsty plants.

Weekend Forecast: For the weekend we go back to our regularly scheduled summer with dry weather starting Friday afternoon and evening. Saturday we return to sunny skies and highs in the low-mid 80's. Sunday through next Thursday we are also looking at sunny skies, with highs in the mid 80's and lows in the 60's.

WeatherWatcher: June Heatwave

Wednesday, June 12, 2019

Photo by Carl Dinse

Winds are from the North and East, skies are sunny, and portable air conditioners have been dug out of storage. All signs point to, yes, we are experiencing another seasonal short-lived heat wave.

High temperatures reported on Tuesday in the Shoreline area:
  • Echo Lake/North City: 84°F
  • Ridgecrest: 80°F
  • Central Market: 78°F
  • Sheridan Beach (Lake Forest Park): 83°F
  • Richmond Beach: 76°F
Wednesday is expected to be the worst of this June heatwave before we go back to our more normal June gloom of morning clouds and afternoon sun. Temperatures across Shoreline and Lake Forest Park are expected to be between 82°F and 87°F.

The closer you are to the Puget Sound, the higher the chance you'll fall into the cooler high temperature range. Generally west of Aurora will stay in the low 80's with places east of Aurora reaching the mid-upper 80's. If you want to experience 90°F you'll have to go south of Northgate or Downtown Seattle.

Cooler air will begin to filter into the area Wednesday evening, which could fire off some thunderstorms over the Cascade mountains for a light show. It doesn't look like we have any threat of those storms in the lowlands but that could change.

The forecast for the rest of the week and all the way through the weekend remains fairly normal for what I would expect in June. Some morning clouds, maybe a drizzle, and afternoon sunshine is expected. Highs are expected to be down in the low to mid 70's with lows in the 50's.

WeatherWatcher: Cooler showery weather on the way

Monday, May 13, 2019

Richmond Beach Rain
Photo by Carl Dinse

Forecast: A change is underway back to seasonable weather for the Shoreline and Lake Forest Park areas. A Pacific stormfront is approaching the coast, threatening to bring a rainy start to our Tuesday morning. A series of Pacific fronts is expected to brush through the area through the end of the week and into next weekend.

Steady rain Tuesday morning could bring us a quarter to a half inch of rainfall, giving our lawns and plants a much needed watering. After the stormfront passes the steady rain is expected to turn into showers Tuesday afternoon.

Tuesday evening through next Monday the forecast is almost identical with showers expected each day and night. High temperatures in the low to mid 60's, with lows in the mid 40's to low 50's. This is much cooler weather than we got used to during the first half of May.

Speaking of temperatures, here's how we did for the last seven days:


As forecasted we were slightly above normal from Tuesday through Thursday last week. Friday and Saturday ended up being the two warm days in the heat wave, with high temperatures just on either side of 80°F at the Richmond Beach station. Away from the water we saw a couple temperatures into around 81-83°F.

This heatwave did break some daily high temperature records for Seattle; however, we've had warmer heat waves earlier in the spring many times in previous years. This type of event is actually fairly typical during this time of year, it just hasn't happened on these exact two days since 1945.
