Cold, slick Saturday morning after WA snowfall Friday

FOX 13 has issues a Weather Alert Day for impacts to residents Saturday morning following a winter storm system blowing through the Puget Sound region on Friday.

SEATTLE - Drier (albeit icy) weather is ahead for Saturday night to Sunday morning in western Washington after an active snowy Friday, but lowland rain and mountain snow return Sunday afternoon.

Earlier this morning, a rain–snow mix developed across parts of Western Washington as a convergence zone set up over portions of King, Snohomish, and Pierce counties. In some locations, snowflakes were not only falling but briefly accumulated on grassy surfaces and rooftops. We could still see minor snow under this zone at about 500 feet in elevation and above it this afternoon before showers diminish.

Temperatures early in the day hovered near the freezing mark for several communities, raising concerns about slushy or icy spots on roads and sidewalks. Areas closest to the Cascade foothills were especially vulnerable to slick conditions where temperatures were coldest.

Through the rest of the day, the convergence zone will gradually weaken and conditions will slowly improve. Compared to the steady wet weather experienced Friday, Saturday will turn out drier with a few brighter breaks.

Rain/Snow Chance and Icy Roads Early Saturday

The frontal boundary responsible for our recent stormy weather will finally slide south of western Washington on Saturday. Behind it, slightly colder air is moving in. That will drop temperatures below freezing Saturday morning and could lead to icy roads in spots.

Puget Sound Convergence Zone snow or a rain and snow mix is possible in Snohomish and King counties early Saturday before temperatures warm up.

Before you get too excited (or worried), moisture will be limited to only a few areas. Many spots in the north and south Puget Sound will be waking up to sunshine.

Brief break before the next round

Late Saturday night, an upper-level ridge will begin building over western Washington. That ridge will briefly dry things out before our next system approaches. Sunday will bring mostly dry conditions with warmer temperatures and more showers developing later in the evening.

Warmer air takes over

Late Sunday into early Monday, snow levels are expected to surge to 5,000 to 8,000 feet. That means the mountains will transition from snow to rain except at the highest elevations. Any new mountain snow early Sunday will become limited as warmer air continues to push inland.

Milder pattern next week

That same upper-level ridge will stick around through much of next week, bringing a noticeable warmup. Temperatures will climb into the 50s early in the week, and by midweek many areas could reach the upper 50s to low 60s.

That is a big change from our recent chilly pattern. Multiple weak atmospheric rivers will keep western Washington mild, wet, and occasionally breezy through the week.
