More Weather Systems Take Aim at Western Washington

Tuesday was rainy with some breezy periods as well. The Tuesday rain totals are below.


Most of the area received 0.1-0.3 inches, a bit less than originally forecast. Some areas, like Tacoma, Gig Harbor, Federal Way, and Edgewood received 0.4-0.65 inches of rain in persistent rain bands that moved through in the afternoon.

Enough on Tuesday...let's take a look at Wednesday and beyond.

Good news! We'll get a break in the weather!

Bad news...the break lasts less than 24 hours (I'm sure you're not surprised)

Let's start off with the rain. Here's the UW forecast for rain from 4 AM Wednesday to 4 AM Thursday.


Expect 0.15-0.65 inches of rain (locally higher amounts are possible), most after 10 AM Wednesday.

Starting Wednesday evening, it'll get breezy to windy across the area. A low pressure system will move into south-central Vancouver Island. By the time of the forecast model image (4 AM Thursday) the low (red L) will be over BC, but Western Washington will experience winds (red arrows).


Expect winds to ramp up after dark on Wednesday, subsiding by midday Thursday.

Here is the 4-forecast blend for Puyallup. (Big numbers=sustained winds, small numbers=wind gusts).


Winds will gust 25-45 mph across the Puget Sound area. I don't expect any major impacts, but be prepared for winds...and keep your outdoor Christmas decorations secure!

Thursday looks to be much drier than Wednesday, save some possible scattered showers throughout the day. 

After Thursday...it'll rain...a lot. The Puyallup Weather Underground forecast shows a total of approximately 4.1 inches of rain through the 22nd (one week away).


While that seems like a lot of rain...it is typical for this time of year. Some breezy to windy conditions are possible with each system as well. You know the drill by now.
