PREVIOUS POST: | A chance of snow and freezing drizzle – enough to create hazards for drivers – is on its way, if it hasn’t hit your area already.
Light snow fell early today along parts of the Washington Coast, and the chance of snow flurries in the Puget Sound will increase by mid-morning, said Chris Burke of the National Weather Service.
Precipitation is expected to be light, with most of Western Washington getting an inch or less of snow through today and Tuesday. Greater accumulations could occur in the Cascade foothills and in the mountains.
The forecast for Seattle-Tacoma International Airport calls for a chance of snow flurries after 10 a.m. today, and a 40 percent chance of snow tonight and Tuesday.
A greater threat to motorists could come Tuesday evening, with the possibility of freezing drizzle as the atmosphere gradually warms up. Burke said warm, moist air moving in over a cold surface layer of air can create rain that freezes as it falls.
A “Special Weather Statement” issued this morning by the Weather Service notes that even in light amounts, freezing precipitation can cause hazardous conditions on untreated roads and sidewalks.
By late Tuesday night, the cold air mass that’s been sitting on the Puget Sound area for several days is expected to have eroded, with temperatures rising into the 40s beginning Wednesday and running through the weekend.
Low temperatures overnight were 24 at Sea-Tac and 21 at Boeing Field. If that seems cold to you, consider what your friends and relatives east of the Cascades are coping with: Overnight lows of 7 degrees in Pasco, 6 in Ellensburg and Spokane, 4 in Moses Lake and -1 in George.
