Later this evening and overnight, there will be pockets of snow in many areas around the Puget Sound region, with accumulations of one to three inches with isolated higher totals. The best chance of heavy snow will likely be in Pierce, King, Snohomish, and Kitsap counties, with locations above 100-200 feet in elevation and particularly nearer the Cascades in line for the most disruptive and heaviest accumulations. It is important to remember that the heavier snow accumulations will be sporadic in nature but this is the best chance for the folks around the Sound to have accumulating snow out of any day of this wintry event.
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.
The outlook for snow accumulations this evening and tonight will evolve as the precipitation moves in and temperatures cool, so the forecast is highly subject to change. A Winter Weather Advisory is in effect into Thursday.
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.
