Tonight: Rain will continue at times across the area through this evening, though some rain shadowing in the lee of the Olympics will keep the Seattle-Tacoma corridor a little drier. Winds are gusty out there from 15-30 mph with a few higher gusts, but winds will die down after about 8-9 p.m. tonight. Also, the Wind Advisory for the coast was cancelled early as stronger winds failed to materialize there.
Friday: Expect a front to move through Friday morning with some heavier downpours, but unlike today, the period of heavier rainfall will be pretty brief. In the mountains, snow levels will fall to below 4,000 feet with this next system so Stevens Pass could get a few inches of snowfall. It’ll be blustery still but high winds aren’t expected and we could even get some sunshine for a time Friday afternoon! Highs will be in the 50s in the lowlands.
Saturday: A vigorous weather system moves through on Saturday with more heavy rain and gusty winds. Winds could top 45mph on Saturday around Puget Sound and even stronger at the coast and north so while no watches or advisories are out yet, we could have some moderate impacts from wind during the daylight hours Saturday with the wind settling down by Saturday evening. The good news is that a lot of leaves are now off the trees and that process is continuing. That could limit tree damage if we do get high winds. In the mountains, snow levels could fall as low as Snoqualmie Pass by Saturday evening but by then the precipitation should be more spotty in nature. However, travelers on I-90 will want to watch conditions beginning late Saturday continuing on through the weekend.

Sunday: Expect more rain at times, though it won’t be as windy. Mountain pass snow will continue to be likely at times with 2-6 inches possible. Highs will be chilly in the lowlands, around 50.
Monday: This could actually be a fairly quiet day with some clouds and sunshine. The break will be brief however.
Tuesday: Forecast models have a potent area of low pressure somewhere near our region Monday night into Tuesday which could cause strong winds across our region if things align just right. But it is too far out for any details to be ironed out and more clarity might not come until late in the weekend or Monday itself as the low pressure system could be quite small in size which would mean the exact track is very important. Even if we just have a typically-breezy day Tuesday, rain would probably be heavy at times. More to come.
Wednesday and beyond: Some signs point to the chance for a ridge of high pressure to bring some drier times, but there doesn’t look to be a major pattern shift to get us out of the rainy and stormy pattern – just maybe a brief reprieve, if we’re lucky.
