Washington Snow Outlook: Storm On Track For Friday Night Arrival

SEATTLE — After an early preview of snow Thursday, the main event will arrive in Puget Sound Friday night, promising several inches of snow across the lowlands. Earlier forecasts remained on track Friday morning, showing widespread, heavy snow moving northward in the afternoon and hitting the Seattle metro by late evening.

Friday morning's lowland totals were highest around Olympia, around 6 inches, and under an inch for most of King and Pierce counties.

A winter storm warning will go into effect Friday at 10 p.m. and remain in effect until 4 p.m. Saturday. Total overnight accumulations are forecast between 3 and 8 inches, with wind gusts between 10 and 25 mph. Heavy snow is expected through Saturday morning, and significant travel impacts are likely across Western Washington.

Strong winds Friday night may limit snow accumulation for communities east of Interstate 5 and Interstate 405, and forecasters expect South Sound totals will be much higher than areas north of Everett.

Friday's frigid air will stick around through the weekend, with Saturday morning temperatures landing in the mid-to-low 20s, with wind chills dipping into the teens. Afternoon highs are unlikely to move out of the 30s across the board.

Sunday's highs will be only marginally warmer, just shy of 40 degrees in Seattle, Tacoma and Olympia.

The National Weather Service is also tracking a third weather system, expected to roll into the area late Sunday. Details on the type and level of precipitation remain uncertain, and it may transition to rain into Monday as temperatures begin to warm. More wet weather is likely next week, which forecasters expect will bring rain to the lowlands, rather than snow.
