WeatherWatcher: Surprise thunderstorm, December graphs, forecast for the week

Monday, December 31, 2018

Radar image December 30, at 1:45AM PST.
National Weather Service in Seattle

Sunday morning we had a surprise thunderstorm develop through Shoreline and Lake Forest Park.

It produced a nice lightning show for residents in the area, as well as causing brief power outages 3-10 seconds long in some neighborhoods.

This thunderstorm was the result of an active convergence zone behind the cold front of Saturday's windy storm. There was heavy rain, and even hail in areas from this storm. Some of the hail even survived until daylight hours in some spots. Rainfall totals at both Richmond Beach and North Ridge were 0.15 inches from the thunderstorm.

December graphs: December had a quiet start, continuing the weather pattern from November before turning active December 9. We came out just slightly above normal in total rainfall for the month, with several rain events, and wind events. We averaged around 3.6°F warmer than normal for the month as well.

December 2018 rainfall at the North Ridge station.

We had three wind storms, on December 14, 20, and 29. The first windstorm only received a wind advisory by the National Weather Service. This storm did the most damage as it was the first significant windstorm of the season, clocking in a peak wind gust of 43 mph.

Our second windstorm was the strongest, and prompted a high wind warning from the National Weather Service, clocking a peak wind gust of 46 mph. The third storm on December 29 earned a wind advisory which ended up being canceled shortly after the high winds peaked at 35 mph. The third storm just didn't quite get as strong as forecast models predicted.

Daily wind gusts at the Richmond Beach Station for December 2018.

The temperature graph shows the story of our above average temperatures for the month. We had several atmospheric river type storms keeping us warm with tropical and sub tropical moisture.

Daily high and low temperatures compared to station average December 2018, Northridge station.

Forecast: New Year's Eve and New Year's Day a cold start in the morning with temperatures in the low 30's or upper 20's. Areas of fog are likely as well, with a high temperature slightly above 40°F.

Our next weather system starts to approach the area Tuesday evening with increasing clouds and lows near 30°F.

Wednesday afternoon the threat of rain returns with temperatures in the 40's. Winds are expected to be on the increase as well Wednesday night through Friday. Some forecast models are hinting at another wind storm Thursday or Friday. Rain remains in the forecast Thursday through next weekend. High temperatures near 50°F with lows in the upper 30's to low 40's.


I'm still looking for photos and info on past weather events in the Shoreline and Lake Forest Park areas. If you'd like to share your stories and photos please send me an email at carl.dinse@shorelineweather.com.

WeatherWatcher: A Wind Advisory has been issued for Saturday

Friday, December 28, 2018


The National Weather Service in Seattle has issued a wind advisory for areas that include Shoreline and Lake Forest Park. The wind advisory is in effect Saturday December 29 from 10AM until 4PM PST. Southerly winds of 20-35mph with gusts to 45-55mph are expected.

Isolated power outages are possible as well as some snapped weak branches. Since this is going to be our third wind storm in just two weeks I'm not expecting the impacts on our local trees and power grids to be significant.


For current weather conditions and wind speeds you can visit www.shorelineweather.com and be sure to check the Richmond Beach station for the maximum wind gusts.

WeatherWatcher: Calmer weather ahead

Monday, December 24, 2018

Daily maximum wind gusts at the new Richmond Beach Station.

We've had quite a breezy month with two wind storms in less than a week. The second wind storm, which prompted a high wind warning from the National Weather Service in Seattle was the strongest of the two. Power outages were less extensive with the second storm, probably because the first wind storm already pruned the trees for us, and the second wind storm, though stronger, was only a little stronger. The Friday December 14 wind storm had a maximum gust of 43mph, where as the Thursday December 20 storm reached a maximum gust of 46mph.

Accumulated rainfall compared to average for December.

We are just a touch below average for rainfall this month so far. The dry start didn't seem to help, but active weather kicked in starting around the 8th of the month.

December daily average temperature compared to station average.

We are running a little above normal for daily average temperatures compared to the average. We had a slightly colder than normal period before the active weather arrived around December 8. A slightly warmer and slightly drier than normal winter season is expected due to a moderate El Niño in the tropical Pacific.

Forecast: We have some calm weather ahead for Christmas Eve and Christmas Day. We have a chance of showers for Christmas Eve, with temperatures in the mid-upper 40's and a slight chance of showers Monday evening with lows dropping into the 30's. Christmas day we are expecting a mostly dry day with temperatures in the lower to mid 40's and light wind.

Our next storm system begins its approach Tuesday with a chance of showers moving in overnight. Wednesday rain is likely at times, with temperatures in the low 40's. Wednesday night through next Sunday we have a chance of showers for each day and evening. Highs will be in the lower 40's, with lows in the 30's.

You'll notice we have a lot of forecasted lows in the 30's with precipitation in the forecast later this week. Occasionally some models have suggested possible lowland snow, but it hasn't been consistent. The majority of the forecast models point to rain showers, with temperatures just a little too warm for snow. I'm keeping an eye on this situation, if a convergence zone develops out of this pattern later next week it can quickly change the story from rain to snow.

Longer range models are suggesting some cooler air moving in after the new year, also an area I am watching closely.

Weather History Series: In celebration of operating a weather station in Shoreline for 10 years now I've been working on a series of weather history articles. If anyone has any good photos of past weather events of any time from the Shoreline or Lake Forest Park area, from wind storms, snow storms, or other weather events that they would like to share, please email them to carl.dinse@shorelineweather.com.

WeatherWatcher: 10 year anniversary of a snowy December

Saturday, December 22, 2018

Shoreline, Washington on December 21, 2008
Photo by Carl Dinse

With famous nicknames as Snowpocalypse, or Snowmageddon, this was a time identified as the Seattle area's snowiest period since December 1990. Starting the evening of December 13 temperatures cooled and snow begin falling, bringing us our first taste of winter. We got close to 2 inches of snow overnight into December 14. It remained frozen until we thawed out the following weekend just barely on December 17.

Starting December 18 a more serious arctic air started spilling into the region bringing with it some renewed light snow accumulations. Low temperatures at the Shoreline station dipped to 16°F on December 19, and 13°F on December 20th.

December 20, 2008

A much stronger storm system moved in the evening of December 21st, bringing significant snowfall overnight and more cold air as well. Sea-Tac reported 6 inches of new snow overnight, but I believe we had closer to 8-9 inches in Shoreline from that storm. We had another storm system move through on Christmas Eve bringing us another fresh couple of inches of snow to insure a rare white Christmas.

Most of my photos during this time were taken after dark due to the short days and long work schedule I had. This was also a time before LED street lights, so we have the pink/orange glow in the sky from the sodium vapor street lighting.

Can anyone else remember the last time they saw I-5 covered in compact snow and ice?

After having nearly a solid two weeks of sub-freezing temperatures, there was close to 13" inches of snow on the ground in Shoreline. We started to warm up December 26th, and most of the snow was melted by New Years Day. This was not the last we saw of winter weather in the 2008-2009 winter season.

WeatherWatcher: High Wind Warning issued, in effect Thursday 7AM - 7PM, Gusts to 60mph

Wednesday, December 19, 2018

National Weather Service in Seattle
Click on the image for a larger view.

The National Weather Service in Seattle has issued a High Wind Warning for the areas including Shoreline and Lake Forest Park. The warning is in effect on Thursday, 7am - 7pm. Winds are expected to increase Thursday morning to 25-40mph with gusts as high as 60mph. The peak of the winds will likely be around Noon - 3pm.

This storm is almost a carbon copy of the storm we had last Friday, so I'm expecting to see gusty winds as high as 45mph, maybe even to 60mph, especially near the water. Snapped branches and downed trees are likely with local power outages. Winds are expected to remain breezy until after midnight.

This storm is expected to bring around a half inch to 3/4 of an inch of rain. Breezy conditions after the windstorm are expected until after midnight. Rain will change over to showers with temperatures dropping into the mid-upper 30's overnight into Friday.

WeatherWatcher: Update on storm statistics, Forecast

Sunday, December 16, 2018

Photo by Diane Hettrick

Now that I have both weather stations back online after Friday's wind storm I can confirm some storm statistics. The National Weather Service, as well, was able to publish wind data from the area which validates the accuracy of my new Richmond Beach station's wind data.

The storm on Friday December 14, was actually on the 12 year anniversary of the Hanukkah Eve windstorm of 2006. The 2006 storm was the strongest storm to hit the region since the Inauguration day storm of January 20, 1993. Winds in the 2006 storm gusted to 70mph, whereas this year's storm brought gusts to 60mph near the water, and gusts in the mid 40mph's in most other areas.

Various reports indicate that the 60mph gusts were the exception, reported on the Edmonds-Kingston ferry, 520 and I-90 floating bridges, and at the wide open airports in the region. Most inland areas from North Seattle through Lynnwood only recorded gusts between 40 and 45mph. Winds were stronger further north and east.

The Richmond Beach station recorded a wind gust at 42 mph at 6:23pm. By an hour later winds had calmed down and the temperature dropped nearly 10 degrees.

Forecast: Our forecast this week is not unlike last week. We will continue to have a series of storms move through the area with rain at times, heavy at times, and several breezy periods as well. Monday is a break in the storms day, with showers around and breezy conditions. Winds could reach up to 30mph.

Monday night into Tuesday the next storm system arrives, bringing wind gusts up to 35mph by Tuesday afternoon. Also a bit of rain, with up to one inch of rain Monday night, and another half inch of rain Tuesday. Highs in the 50's, lows in the mid-upper 40's.

Wednesday through Thursday night rain is likely, with breezy conditions at times. High temperatures in the 50's, lows in the mid 40's, but cooling down to the upper 30's Thursday night.

Friday through next weekend the weather is expected to calm down a bit with a chance of showers and highs in the 40's and lows in the mid 30's.

WeatherWatcher: First real windstorm of the season

Friday, December 14, 2018

City Light outage map at 10pm
City Light in total has 46,000 households without power

The high wind watch was upgraded to a high wind advisory by the National Weather Service in Seattle Friday morning. That advisory should have been a high wind warning after the storm hit.

Winds of 20-35mph were expected with gusts to 45mph. In actuality, we had winds of 25-40mph with gusts to 60mph throughout the entire area between Seattle and Everett. Easily strong enough to meet high wind warning criteria.

The Richmond Beach station lost power during the second half of the storm. Before it went offline, the peak wind gust at 6:23pm was 42.6mph. This is proving to be a very successful weather station for Shoreline. Central Market saw a gust of 34mph, a personal weather station near Parkwood saw 38mph. The Edmonds - Kingston Ferry recorded a wind gust of 60mph, as did both floating bridges on Lake Washington.

All the weather stations I could find that didn't lose power during this storm generally reached between 58 and 62mph around the region north and south of Shoreline and Lake Forest Park. I think it's safe to assume we had winds just as strong as well.

Here's the current dashboard and graph from the Richmond Beach Station, last updated at 7:40pm (power went out a few minutes afterwards.)

Richmond Beach Station

Even the Northridge station, surrounded by mature Douglas fir trees, recorded a gust of 21mph at 6pm shortly before losing internet connection. Far as I can tell we still have power and battery backup on the Northridge station so when internet comes back we'll get to see how windy it got there.

North Ridge (Echo Lake Neighborhood) Station

Temperatures are another story as well, but I'll have to talk about that in my next weather report when we get data back from the local stations. We started the wind storm with temperatures 54-55 degrees. By the time the wind storm was over we dropped down to the low 40's.

One of the biggest challenges tonight with finding storm data is that many of the weather stations in Shoreline and throughout the region in general lost power and/or internet during the height of the storm. The National Weather Service office in Seattle also lost power. The Portland, Oregon National Weather Service office had to take over operations for the evening for the Seattle office until power is restored.

I'll have the forecast and full data report out Sunday morning. For current conditions and information you can visit www.shorelineweather.com.

WeatherWatcher: High Wind Watch for Friday

Thursday, December 13, 2018

National Weather Service in Seattle

The National Weather Service in Seattle has issued a High Wind Watch for Friday December 14, 2018 for the area that includes Shoreline and Lake Forest Park. The high wind advisory for Thursday December 13 was cancelled at 4:41am, with strong winds were no longer expected for Thursday. We had a maximum wind gust at the Richmond Beach station Thursday morning of 27mph shortly before 7am.

The high wind watch is in effect from Friday morning at 10am until Friday evening at 7pm. There is a lot of uncertainty with this storm, depending on where it makes landfall. Most models show the winds peaking around 1pm, with a second handful of models having the winds peak later in the evening around 5-7pm. Winds could gust as high as 60mph through the area if the storm makes landfall in just the right spot along Vancouver Island.

Updated Forecast: After our wind storm Friday things are expected to calm down a bit for Saturday as we have another break in the weather before the next storm system arrives. Showers are possible on Saturday, with temperatures in the low 50's.

Sunday our next storm comes in bringing breezy conditions and more rain. We have a forecast for rain at times through next Thursday, with highs in the low 50's, and lows in the mid 40's. With all of these storms we are getting a lot of mountain snow, so that should help our snowpack drought we were having in November.

WeatherWatcher UPDATE: High Wind Advisory issued for Wednesday night with bigger storm Friday



The National Weather Service in Seattle issued a high wind advisory for the Shoreline and Lake Forest Park areas at 3:06PM PST Wednesday. The wind advisory is in effect until noon Thursday. We are expecting 20-35mph winds from the south with gusts up to 50mph.

Winds are expected to pick up Wednesday evening with the strongest winds early Thursday morning. Local power outages are possible as well as downed tree limbs.

A wind advisory means winds of 35mph are expected.

Updated Wednesday at 10:25PM:
A much more serious storm is expected on Friday as of Wednesday evening's special forecast update. A deepening low pressure system is expected to approach southern Vancouver Island early Friday morning.

Winds are expected to increase shortly after midnight Friday morning, gusting to 40mph. By late Friday morning southeast winds of 25-40mph are expected with gusts up to 55mph. Winds are expected to gradually decrease in the afternoon and evening hours of Friday. Winds this strong can cause numerous power outages, fallen tree limbs, and fallen trees.

At this time there has not been a high wind watch, advisory or warning issued for Friday. I anticipate that the National Weather Service will have some kind of advisory or warning issued by Thursday afternoon or evening for Friday. Check back here or at my website for updates on watches, warnings or advisories.

WeatherWatcher: December back to normal

Monday, December 10, 2018

Clouds before the rains, at Richmond Beach, winter season 2001-2002 on 35mm film.
Photo by Carl Dinse


The jet stream is back in the Northwest where it belongs during winter months. We are expecting a series of seasonal storms to move through this next week or so.

We have a slight break Monday with showers, before our next storm system moves in Tuesday morning. Rainy and breezy conditions are expected Tuesday and Tuesday night. Wednesday will be another "break" day with a chance of showers. Thursday a heavy rain storm moves in. The rain may be heavy at times, especially Thursday evening. More rain Friday, with a chance of rain next Saturday. Rain likely Saturday night and Sunday.

Temperatures all week and next weekend in the 40's for highs, lows in the upper 30's to low 40's. This is really good for mountain snow so it should hopefully help with that snow drought in the Cascades and Olympics we've been having this fall.

For December so far a dry and chilly start, but Sunday signals the change. Our first weaker weather system last Friday night into Saturday morning was too weak and most of the precipitation evaporated into the drier colder air near the surface before reaching the ground. The second system on Sunday brought us a half inch of rain. Here's the temperature and rain graphs for December:

WeatherWatcher: Very slight chance of the S word possible early Saturday morning

Saturday, December 8, 2018


A scenario that always catches forecast models in the Puget Sound region off guard is happening early Saturday morning. When you have cold, dry air in place with an approaching storm front off of the Pacific such as we do tonight, an experienced forecaster will look at temperature and dew points.

If you have an air temperature of 35°F and a dew point of 25°F, and suddenly throw precipitation into that air mass, the evaporation of the precipitation into the dry air cools the air until it saturates. As the air saturates, the dew point temperature will increase, and the air temperature will decrease until the two temperatures are the same, typically landing about halfway in between.

Using the above numbers of 35°F and 25°F, the air mass would saturate down to an air temperature of about 30°F and instead of rain, you'd get snow. Often this is overlooked, especially when today's weather forecasts depend so heavily on computer models.

I did a quick check on my weather stations for the Echo Lake area and Richmond Beach area. Both stations have a low dew point, 29°F at Northridge (Echo Lake), 23°F at Richmond Beach, with air temperatures at 37-38°F. It is marginal, but we could get very near 32°F when the precipitation arrives at about 1-2am. I checked the radar and it does show areas where precipitation has already started near Olympia as rain and snow mixed.

Light rain could start as rain and snow mixed, or even snow in the early morning hours in Shoreline and Lake Forest Park. 

I'm not expecting accumulation with this. At most it would be a show of wintery weather for the few that might be awake in the early hours of the morning. The storm front moving through is weak, but expected to warm us up slowly into the low-mid 40's tomorrow mid morning and afternoon.

Bottom line: Maybe some snow or rain and snow mixed overnight, all light rain by late morning. No accumulations expected. We have a stronger, all-rain storm moving in Sunday as well. I'll have more on the forecast late Saturday night.

WeatherWatcher: Drying out and cold for a week

Sunday, December 2, 2018

Frosty Morning
Photo by Carl Dinse

Colder and drier air is moving into the area as the main jet stream moves south into California this week. Monday through Friday we are expecting mostly sunny afternoons with highs in the low to mid 40's and clear nights with lows in the upper 20's to low 30's. There may be areas of fog in the overnight hours all week as well.

Later half of the week the lows will be slightly warmer, near 30°F for a low. Next weekend, some weak weather systems will approach, warming temperatures up a bit and renewing a chance of rain showers for both Saturday and Sunday.

November in review: November was warmer and drier than normal this year. Average temperature this November was 45.9°F whereas the normal for November is 43.7°F. We had a total rainfall of 4.37 inches, compared to the normal of 6.63 inches of rain. Our first four days of the month were pretty windy, with gusts exceeding 30mph each of the first four days.

I've included graphs for the month of November below:




With our moderate El Niño and warm phased Pacific Decadal Oscillation I'm expecting the drier and warmer than normal trend to continue for the month of December as well with very slim chances for any lowland snow events.

WeatherWatcher: Wind and a lot of rain on the way

Sunday, November 25, 2018

Photo by Mike Remarcke

November's dry period is being replaced with exceptionally rainy storms. We have so much rain expected this week that we might meet or exceed the normal rainfall amount for the month. Here we are so far for November's rainfall:


We are expecting increasing rain to start shortly after midnight Monday morning. Rain is expected to continue almost non-stop until next Saturday. Monday afternoon and evening winds are expected to pick up. Gusts could reach up to 40-45mph Monday evening. I'm not expecting any significant wide spread tree damage or power outages with this one. The big story is that we could see between 1-3 inches of rain by Wednesday.

Temperatures reaching the low 50's for highs and the upper 40's for lows all week. Next weekend might cool down by a couple degrees. Here's the daily average temperature graph for November so far:

WeatherWatcher: Dry weather ends, long range outlook

Wednesday, November 21, 2018

NE 185th St at 5th Ave NE, February 7, 2015.
Photo by Carl Dinse


Dry Weather Ends: Wednesday morning is likely to be the last few hours of dry weather left in November. A weather system is approaching as our upper level ridge of high pressure moves east. The jet stream is shifting from the north in Alaska to the west coast and is expected to bring a series of storms with it.

Wednesday there is a slight chance of rain in the morning, then rain is likely in the afternoon. We are expecting rain to continue through the evening switching over to showers after midnight. We could get between a quarter inch to a half inch of rain. High around 50°F with lows in the 40's.

Thanksgiving Day, true to the Pacific Northwest tradition, will feature a moderate rain storm with high winds. Models have been a little inconsistent with how strong winds will be. Right now we are expecting winds of 20-30mph with gusts as high as 40mph. High temperatures will be in the low 50's with up to a half inch of rain.

Thursday evening through Friday evening we are expecting to have rain continue at times, highs falling to the upper 40's and lows down to the mid 30's Friday night. We are expecting a bit of a break on Saturday with mostly sunny skies, temperatures near the upper 40's. We have a slight chance of rain Saturday night and Sunday.

Monday the rain returns lasting through Tuesday and possibly further into next week, high temperatures reaching the lower 50's and lows in the 40's.

Long range outlook: Officially we are heading into a moderate El Niño winter. Typically this means that we are expected to be above normal in temperatures and below normal in precipitation. For Shoreline and Lake Forest Park, look back to the 2014-2015 winter and the 2006-2007 winter as examples of what to expect. Overall it should be a fairly mild winter with more uneventful weather than normal.

Snow chances are less likely; our best window for lowland accumulating snowfall is between December 15th and January 15th. Much of the weather beyond January 15th is expected to be too mild and dry for any snow threats. There could be a windstorm or two; chances are somewhat equal for those during an El Niño season. December will probably be our best month for active weather.

WeatherWatcher: Forecast, back to back wind events

Sunday, November 4, 2018

Forecast: Calmer weather is ahead after last week's stormy weather. Monday through Tuesday night we have mostly cloudy skies and a chance of showers, highs around the mid 50's and lows in the 40's. Wednesday through next weekend we are expecting mostly sunny weather with highs in the lower-mid 50's, lows ranging from the low 40's and upper 30's.

Last week we had a series of storms, and atmospheric rivers impact the region. We actually didn't get as much rain as other areas did because of the Olympic Mountain rain shadow.  We had two wind events. Both mainly impacted Snohomish County but the southern edge of the winds reached parts of Shoreline and Lake Forest Park.

Thursday night a wind event peaked around 11:30pm with gusts at the Richmond Beach station reaching 35 mph. No wind advisory was issued for this storm. Saturday night a better forecasted storm impacted the area. This one earned a wind advisory issued Saturday morning for Saturday night and Sunday morning. Gusts were expected to reach between 35mph and 45mph. Once again the Richmond Beach station recorded a gust of 35mph at 1:11am PDT Sunday morning.

The winds probably didn't seem as bad the second time around because it was about the same speeds as our Thursday night storm. Saturday night's storm had wind gusts further apart from each other than Thursday night's storm. Trees and tree limbs that would have problems in these winds have already been pruned out by Thursday's storm so power outages were probably small, scattered or nonexistent.

October averaged about 0.8°F colder than normal, with below normal rainfall to end the month.

Here are the rain graphs for October:

WeatherWatcher: Windy, uncertain forecast

Friday, November 2, 2018

We've had a windy evening with wind gusts up to 33mph as recorded at the Richmond Beach weather station. You may have noticed we also remained mostly dry on Halloween. There has been a significant change in the forecast.

The heavy rains we've been expecting have been either to the north or to the south of Shoreline and Lake Forest Park. The Olympic Mountain rain shadow has been strong with these storms, keeping us mostly dry relative to other areas in Western Washington.

Going forward, we are expecting breezy to windy conditions to continue into Friday morning. Winds are not strong enough to meet high wind advisory or warning criteria, gusts could be between 30-40mph. Rain is expected to pick up overnight and into Friday morning with breezy conditions continuing through Friday afternoon. Friday evening there's a slight chance of showers, and winds will be calming down a bit.

Saturday is expected to be mostly cloudy with a chance of showers, then in the afternoon or evening the next weather system arrives with more winds up to 40mph and rain. Rain is expected to continue through Sunday with the early part of next week being cloudy with showers.

Temperatures are mild, in the mid to upper 50's which is typical for this time of year, especially when we have these atmospheric river type systems moving through. We may see a break in the active weather mid-late week. Timing of these systems with this forecast may be somewhat uncertain and rains may hit a half day or full day early or late.

Overflowing storm ditch in Lake Forest Park
Photo by Carl Dinse

Forecast: We have a lot of rain in the forecast for this week. Most models are showing between 1-2 inches of rain between now and next weekend. Temperatures are expected to be a bit above normal as well, highs in the mid and upper 50's all week with lows near 50.

Monday-Tuesday we are expecting mostly cloudy skies and showers that will be a hit and miss nature, much like we had on Sunday. Tuesday evening the next big rainmaker moves in with steady rain increasing overnight.

Halloween we are expecting steady rain day in and day out, so it's going to be very wet for trick or treaters. The rain is expected to continue through Friday, heavy at times. We might have a break into showers sometime Thursday. The weekend looks to be cloudy with showers both Saturday and Sunday.

Last week we had some significant rainfall to make up for our dry period. On Saturday alone we received right about 1 inch of rain total for the day. We could very easily pick up enough rain this week to make the average rainfall for the month.


Our temperatures increased a bit above normal when the rain storms came in. I think it'll be enough to push us above normal in average temperature for October.


With all these heavy rains and a lot of foliage on the ground we could see some urban flooding. Be sure to check those local storm drains and help keep them clear of debris.
