As the upper-level low pressure system weakens offshore, it is moving closer to us and will cross the area on Friday. This system was responsible for yesterday’s thunderstorms and while the atmosphere is still weakly unstable, the cooler surface temperatures will rob any thunderstorms of significant power this evening and tonight.
That said, there is still the chance for a few lightning strikes, mainly this evening with any heavier downpours. It’ll also be blustery at times with breezes strongest at the coast.
Into Friday morning, expect showers to continue with morning temperatures in the 40s. In the mountains, there will be a little high elevation snowfall but nothing of serious note through the passes. By afternoon, there will be more rain with only a very slim chance of a thunderstorm. Highs will be in the lower 50s.
The weekend is looking brighter with some rain around on Saturday through about early afternoon before tapering. There will be sunbreaks through the day and highs in the 50s. Sunday looks to be the best day of the weekend with some morning clouds and fog and then partly sunny skies and highs in the low 60s in Seattle. That should be a fine day to go see the cherry blossoms at the University of Washington (along with a lot of other folks, I suspect.)
Rain showers and cooler temperatures with mainly cloudy skies return on Monday and persist through at least Wednesday, if not Thursday. This will be a rather dreary set of days with highs a couple degrees cooler than average — in the mid 50s in Seattle. The mountains will get some snow at times, though heavy snow doesn’t look likely.
It could get brighter and possibly warmer by the end of next week.
