Stormy Couple Days On Tap!

Happy Sunday! Most of the South Sound has received around a half inch of rain since midnight. More is to come over the next couple days, along with wind and a chance of thunderstorms. Let’s take a look at the details!

As the steadier rain moves out of the region this morning, showers (and eventually wind) take its place. Here is the NWS Seattle graphic showing the wind forecast. 

You’ll notice that our area gets gusts of 20-25 mph, with higher gusts (30-40 mph) possible. Winds will increase through the day today, and peak early Monday morning. 

The next aspect of this storm is rain. Lots of rain compared to the relatively light rain we’ve had recently. Take a look at this forecast model showing expected rain through the next 3 days. 

Wow!! Almost 2 inches of rain!! Most of the rain will fall from Sunday night to Monday night. This won’t be enough rain for flooding, but it will be nearly the same amount we have received in all of the past month!

Thunderstorms are also possible with these systems. The highest possibility for scattered thunderstorms will be during the day on Monday and Tuesday! Be prepared!

One more thing...mountain snow. This storm will produce a huge mountain snow total for late March. Snow levels will be down to 2,000 feet, so that means that Snoqualmie Pass gets 12-18 inches by Tuesday! If you are traveling over the mountains, be ready for winter storm conditions. 

After these storms move out late Tuesday night, expect mostly cloudy days with a chance of rain (and some sunbreaks, of course) each day to round out the week. 

Drier Then Turning Rainy

For most of us, Wednesday has been a dry day. There has been some passing showers, but not much else. Rain will move in tomorrow, later in the day. Let's examine the details...

Rain moves in on Thursday night, and the precipitation chance increases, along with the amount of rain, through the night. After that, rain is likely to continue through the weekend. Take a look at this forecast model, showing rain through Sunday night.

Most areas receive 0.45-0.5 inches of rain. Not a ton, but a decent amount for a 2ish day storm! 

Rain will continue through at least Tuesday night, and our totals will range from 0.9-1.1 inches of rain! 

Temperatures will be normal for early spring, highs 48-55, lows 37-44. 

Sun Transitioning to Rain

It has been an absolutely gorgeous week, with sun every day and multiple days above 60 degrees! We’ll continue the sun through Saturday, before clouds and eventually rain move in to the area.

I have personally enjoyed being able to get outside each afternoon and feel the warm sun and see the beauty of the PNW. I was able to capture this beautiful sunset through a tree on Wednesday night. Sometimes, you just need to look in the right place and you’ll find the beauty!

We will enjoy one more sunny day on Saturday, before clouds and rain slowly move in from Sunday to Monday. Saturday’s high will be in the upper 50s, so get out there and enjoy the last sun for a bit! 

As we make our way through the weekend, clouds move in and temperatures drop. Sunday will be mostly cloudy, and high temperatures will drop from the upper 50s to the upper 40s. Rain moves in on Monday, turning to showers by Tuesday. 

There is a chance of more weather systems through the week. It will remain mostly cloudy through at least next Saturday.

Sunny Week Ahead

As the clouds move out today, we will transition to a sunny stretch of weather!! Let’s take a look at the details...

Cold NE winds will continue through Monday night, gusting 15-30 mph. Clear nights also means cold temperatures...and we will dip below freezing Sunday, Monday, and possibly Tuesday nights. Lows will be 28°-32°.

We will warm up dramatically tomorrow, with highs reaching the mid 50s, instead of the low 40s like today. Monday to Friday will be sunny with highs 50°-60°! Yes, you read that right...60 degrees is possible!!

After Friday, we will cloud up some more, as there’s a chance of rain. Here’s a graphic from NWS Seattle that shows our weather for the next 5 days!

Active Weather Day Starts With Snow

It can snow in March!! As the morning's snow melts away, it will bring forth a day of active weather. It was a little "boost" to everyone to see some pretty snow on the ground today, and I took some time to take some pictures of the event...take a look!

As the temperature warms into the mid-40s for today's cold high...this snow will melt. It will give way to rain, as a cold front moves through today. This cold front will also draw in cold NE winds. Let's get right to the details...



This graphic from NWS Seattle shows the expected winds. In the Central & South Sound, expect NE winds 15-25 mph, with gusts 25-40 mph from Friday afternoon through midday Saturday. 

Another weather impact that will be arriving is unseasonably cold temperatures. Lows on Saturday, Sunday, and Monday will dip below 30 degrees, and it will be as cold as the mid-20s in some spots. Another graphic from NWS Seattle shows some expected low temperatures this weekend.



Remember, it will most likely get colder than this at times, especially in the valleys and closer to the mountains. Expect dry conditions with lows 24-30 degrees.

High temperatures will stay in the mid-upper 40s through Sunday. After that, expect sunny days and cold+clear nights! Highs approach 60 degrees by the middle of next week!!

Unseasonably Cold Weather This Weekend

2020 has been a year of strange weather. As we roll in to March, that will continue. This week has already featured a monthly low of 27 degrees. For the rest of the week, rain, sun, and snow are possible. Let's take a look at the details, especially that chance of snow :)

A system moves through on Wednesday, then we will have a dry day for most of Thursday. After that, it gets interesting. This graphic from NWS Seattle shows expected weather impacts for these next couple days. Gusty east winds will be prevalent from Friday through Sunday, with winds gusting 15-35 mph in our area. 

As we move in to the night on Thursday, cold air will be moving slowly south. This model from the UW shows the cold air just north of Washington on Friday afternoon. 



This cold air is the white, blue, and purple colors on the map. This air will sag south in to Western Washington by Saturday. Temperatures will struggle to reach 50 during the day, and at night we will see low temperatures between 25 and 32 degrees. That is unseasonably cold for March. 

Because of this cold air, and some left over precipitation from the days before, there is a chance of snow from Friday night through Saturday. Here is the UW WRF model, which shows 0.7-1 inches of snow. 



The Canadian (GEM) model is more ambitious, showing up to 2 inches of snow through late Saturday. Take a look...

As always in Washington, this is only a *CHANCE*...so we will have to see how this situation changes as the week moves forward. 

The cold weather will intensify as we get later in to the weekend, and temperatures on this UW model for Sunday morning shows temperatures 20-25 degrees for Western Washington and 15-20 degrees in Eastern Washington. 



This will be a significant problem to anyone who has plants or crops planted already. Saturday and Sunday nights will be the coldest, in the 20s for nearly all of Western Washington.

Sunny Days & Unseasonably Cold Nights

Yesterday felt abnormally chilly...and today has been another one of those days. Let’s take a look at what to expect the next few days:

Like I mentioned earlier, today was chilly, and as the showers & clouds clear out tonight, lows will dip down to the upper 20s-low 30s. There is a slight chance that pockets of left over precipitation will fall as light snow on hilltops, but this is unlikely.

As we “Spring Forward” into Sunday, the weather will get nicer! Sunday and Monday will be mostly sunny and crisp with highs 48-52. No clouds will allow for temperatures to get colder these few nights, with lows 26-32 and possible frost/ice. Those overnight temperatures are unseasonably cold for March, but we will moderate slowly after Monday night. 

Clouds increase on Tuesday, and temperatures become more seasonable, with highs in the mid 50s and lows in the mid-upper 30s. Chances of rain increase with a system on Wednesday, and then again as a stronger, more organized system makes its way in on Friday. 

Also, be sure to get some more sleep tonight...as we transition in to Daylight Savings Time
