Updated Friday 5:05 p.m.
As Paul Deanno beautifully wrote in his internal e-mail to our staff for the morning weather forecast: "You can stick a fork in this crazy weather pattern because it's just about done."
Although it's not necessarily sunshine that will be cooking said weather pattern this weekend. We've still got a lot of rainy and breezy days on the horizon, just more along the lines of, "hey, it's windy outside" instead of "hey, where did the lights go...and why does this garbage can have an Oregon address?"
Tonight is what passes for a lull these days, but we'll still see frequent showers amid breezy winds to 30 mph as a trough of low pressure swings through. One shower up in the San Juans graduated to a thunderstorm as the center part of the storm passes nearby, but it'll be gone soon. Also be on the lookout for some convergence zone rain between Seattle and Everett after midnight. It is expected to also be occasionally snowy in the mountains, with 5-10" possible, especially in the Conv. Zone spots near Stevens Pass. Lows will drop to the upper 30s.
Saturday should begin calm with perhaps a few drip-drop showers, but our next weather system won't wait too long before charging back inland. Steady rains will develop along the coast in the morning, spreading into the I-5 corridor around midday-ish and lasting through the night. This will also kick up the winds again, but to 40 mph on the coast, and 25-35 mph inland; highest north. Highs will only reach the mid 40s.
Special note to WSU travelers:-- I know your Thanksgiving week begins now and a lot of students will be driving back toward Western Washington for the holiday week (had a few concerned parent e-mails). I'd say Saturday morning to midday is your best chance to get over I-90 with the least chance of snow, although keep an eye on the Convergence Zone in case it persists and drifts south. Snow will be increasing in the pass as we get into the afternoon and evening and it's expected to be quite snowy Saturday night into early Sunday, then showery with occasional snow bursts Sunday.
Sunday should see some early rains calm to showers for the balance of the day, but another Convergence Zone is ripe to form, keeping the rain going between Seattle and Everett. Highs will stay a little chilly, reaching the mid 40s.
Another wet and breezy day Monday, but we think once again garbage cans will stay within their home states. The pattern then starts to calm down even more -- so much so that we almost squeezed out a dry day!
Almost.
It looks like we'll get brushed by a weak warm front on Tuesday -- good for a few light showers or short periods of light rain, enough to count as a rainy day, but probably not enough for Seattleites to notice. Highs will warm a touch to near 50.
Wednesday is even closer to a dry day -- the system's cold front stalls offshore in the morning, leaving us dry(!), and then the front begins a slow drift inland. It'll be a race whether it can get here before the daypart ends, but we think some sprinkles will sneak in before the day is done.
Showers are around for Thanksgiving, but as of now Friday is... well, I don't want to jinx it. Let's just say there are some blue orb-like graphics that are not on Friday's forecast that do appear on the other six days :) Maybe some perfect weather to get some exercise after the workout your fork will get on Thursday :)
Have a great weekend!
