Remember how Seattle smashed an all-time record with the first 14 days of May being at or warmer than 65 degrees?
No? I can't blame you.
A day after Seattle broke the record for coldest May 22nd on record with paltry high of 52, it's managed Thursday to get all of one degree warmer. It's as if all of a sudden we've adopted the "I can't drive 55" song as our mantra this week (although I believe the issue with the song was being stuck over 55, not under :) )
But 50s are what to expect when we steal our weather from Alaska. A low that was born up there has been aimlessly spinning around the Northwest this week and unleashing its Last Frontier chill, but is finally pegged to weaken a bit and allow our temperatures to climb closer to modern-day speed limits.
(Unless you were in the far North Sound and farther away from the low's effects. It actually was around 60 up in Skagit and Whatcom Counties)
Tonight will remain mostly cloudy with rain at times (especially central and south Sound areas), decreasing late. Lows will be in the mid 40s.
Friday should be a bit brighter, drier, and warmer as the low continues to move farther away. We'll still have a risk of showers but they'll be brief and light -- with more in the way of sunbreaks. Highs should "warm" into the low 60s for much of the area, except in the North Sound, where they'll remain in the low 60s.
We still have some very weak remnants of the low hanging around this weekend which will keep the atmosphere very weakly unstable. That means still a chance of showers, but they'll mainly be in the afternoon/evening and be primarily in the foothills and mountains. We can't say zero chance of rain around Seattle but it's probably not too much higher than zero -- maybe 10-20 percent. (I realize I am pressing our luck tapering rain expectations with it being a 3-day weekend) with Saturday's rain chances slightly higher than Sunday's. But for much of the area for the vast majority of the time, it'll be partly sunny days with highs in the mid 60s.
Memorial Day Monday is a bit of a wild card now as forecast models debate what to do with an incoming front. They all agree that Monday should start dry and stay that way through early afternoon. One model shoves that system farther south and leaves Monday dry but another now brings light rain in by mid to late afternoon. So stay tuned there. It does look like rain will be around on Tuesday as well unless that system totally turns south.
Long range models continue to stick with a showery pattern next week with highs around to perhaps a little below normal, but still warm enough to stay out of the slow-poke lane :)
