Following an evening of hail and snow showers in King and Snohomish County -- and even a report of a waterspout over Puget Sound -- attention turns to more chances for snow later this evening and tonight.
Through early Thursday morning, the best chances for snow accumulation of 1-3″ with isolated higher amounts looks to be in the central and north Sound, across parts of King, Kitsap, Snohomish and Island counties. Locations nearer the Cascades will also be favored for snow, as well as west of Puget Sound along Hood Canal and west of Olympia.
Be very careful driving overnight as falling temperatures below freezing will also bring the chance of patchy ice.
Across the far south (Thurston/Lewis counties), the coast, and north interior, the chances of significant snow is a little lower with the exception of some heavier snow in western Whatcom County and the Port Angeles area of a couple inches. Still, there will be some accumulations.
Snowfall will likely be lingering around the Central Sound into the morning hours before fading toward midday. We’ll have some afternoon sunshine with highs in the 30s.
With mainly clear skies, the coldest night since January 2024 is likely to start Friday with a Cold Weather Advisory in effect for morning lows in the teens in the colder spots to the low to mid 20s in the cities of the Sound. Highs on Friday could approach 40 as another weather system moves in. This will produce some light to moderate snow into late Friday night and early Saturday before a drying trend. Travel could be difficult again Saturday morning.
Drier weather is probable into later Saturday and Sunday but we can’t say for sure there won’t be a snow or mixed precipitation shower at times. Same into early next week.
It appears we will be much colder than average until at least the end of next week, possibly beyond.
