Some areas of Western Washington saw some snow showers Saturday morning as a convergence zone stretched from northeast Jefferson County southeast into southern Snohomish and northern King counties.
"We have enough cool air aloft for heavy showers to fall as a wintry mix on the higher hills, but as our winds have changed, drier conditions are on tap for the afternoon," said Lisa Van Cise in the KING 5 Weather Center.
Snowfall has been heaving in the Cascades. Nearly 48 inches of snow fell at Stevens Pass in a 24-hour period. The Summit at Snoqualmie reported 18 inches in a 24-hour period.
Drivers on I-90 ran into compact snow, ice and slush past North Bend. The Washington State Department of Transportation warned drivers to be careful and are advising traction tires for the pass.
"It can change very quickly up here," said Washington State Trooper Grant Campbell. "You should be prepared for anything, keep chains in your car, as well as blankets and water."
Early Saturday, hundreds of people were arriving at the top of the mountain for the opening of the ski season at The Summit. By 9 a.m. the ski area's first parking lot was full.
The National Weather Service said snowfall rates at Stevens on Saturday morning were upwards of 2-3 inches per hour at times. Additional accumulations of 4 to 8 inches were expected to fall at Stevens pass before the convergence zone eventually shifts and gradually weakens.
Twenty-four hour totals ending at 5 a.m. Friday were 14 at Snoqualmie Pass, 21 inches at Stevens Pass and Mount Baker, and 18 at Paradise on Mount Rainier.
Snowfall so far this year at Mount Baker is more than 100 inches.
A weakening warm front will push in on Sunday for an increasing chance of rain during the day, said Van Cise.
"There's a slight chance the precipitation could begin as wet snow over the south end of Hood Canal and the western part of the Kitsap Peninsula," she said.
The front will dissipate over Western Washington on Sunday night. Highs over the weekend will be mostly in the low to mid 40s.
