We have a slow-moving front bringing rain into the coast and Olympic Peninsula the next few hours, then sliding into the rest of Western Washington tonight into Thursday morning. An associated low pressure area across the British Columbia coast is also bringing some gusty winds to the coast and north with some wind gusts 30-40 mph, and this will continue into the night tonight. Elsewhere, wind gusts of 25-35 mph can be expected into tonight. These winds will subside slowly into Thursday morning.
Meanwhile, rain will continue to be around early Thursday with only a few breaks during the day. Expect rainy travel with highs tomorrow in the upper 40s to near 50. Spring officially begins at 2:01 a.m. Tuesday.
In the mountains, a Winter Weather Advisory is in effect for the Cascades for Thursday for 6-12″ of snow falling from tonight through Thursday night. Pass travel will be slippery at times.
More rain and mountain snow are likely Thursday night and Friday and it’ll probably be breezy once again. Another 6-12″ of snow could fall in the mountains though less at Snoqualmie Pass. Highs will be around 50.
Saturday will be drier with only a few scattered showers before more rain and high-elevation mountain snow on Sunday, however rain could fall at higher slopes later in the day. There is the potential for heavier rain to end the weekend and start next week, so we’ll be monitoring that, but the heaviest rain could stay north of the Canadian border.
A ridge of high pressure builds in with much warmer weather Monday through Wednesday of next week. While Monday and Wednesday will have some rain chances, Tuesday looks partly sunny and dry. Highs will be in the 60s in Seattle with the Tuesday forecast high of 67 degrees a record high for the date.
We’ll return to 50s for highs and rain chances late next week.
