Heavy mountain snowfall expected Wednesday, Thursday – KIRO 7 News Seattle


WESTERN WASHINGTON – A winter storm warning is in effect as heavy mountain snowfall is expected Wednesday evening and Thursday.

The storm warning is for the corridors at Stevens and Snoqualmie Pass, where an additional 6 inches or more of snow is expected.

Some of the heaviest snow bands will move north late Wednesday, with the possibility that Stevens Pass will receive more snow than Snoqualmie Pass; however, both passages will be slippery.

It will be difficult to cross the passes on Wednesday and much of Thursday with a weather system bringing a foot or more of snow with snow levels below the Snoqualmie Pass.

The eastbound I-90 at Snoqualmie Pass closed Wednesday afternoon due to multiple diversions. It was reopened and then closed again so crews could clean up the mess and improve road conditions on the hill by breaking up snow and ice on the road.

Showers will continue to fall in the lowlands overnight as snow levels remain above 1,500 feet south of Everett.

And north of Everett, centered in Skagit County, a heavier convergence zone could produce a rain-snow mix, causing slush to accumulate mostly on grassy areas above 100 feet elevation. There will be a few pockets of rain or drizzle but no major weather issues in the lowlands early Thursday.

Temperatures will only rise up to 40 degrees with showers and sun breaks throughout Thursday. An isolated thunderstorm near the coast and perhaps a downpour of hail or hail in the lowlands could appear. Intermittent snow showers will also fall in the passes.


Friday will look like Thursday as some areas can experience rain and snow in the mountains.

A strong weather system will arrive on Saturday with more mountain snow – sometimes heavy – and a lot of rain in the plains. Potentially strong winds of 40 mph or more could arrive in the area from the south on Saturday morning. This could cause power outages in some places before the wind dies down later in the day. The passes are expected to receive 8 to 18 inches of snow Saturday through Sunday, with over 2 feet of fresh snow on the higher slopes, which will be a hit with skiers and boarders alike.

It looks very promising for other station openings ahead of Christmas week.

Early next week snow levels could drop and there could be snow on some higher hills.
