Weather forecast for Saturday 5 November | Time

0

Clouds form overnight as we fall in the mid 30s to upper 20s for most of the region.

Winds will still be strong tonight with gusts over 20 mph but a huge decrease from yesterday.

Cascades overnight will see a gradual increase in precipitation early Sunday morning.

A low pressure system is moving south over the Olympic Peninsula dumping heavy rain and snow on the windward side of the Cascades.

Mountain ranges could see a total of 15 to 24 inches by Sunday evening near White Pass with 12 to 18 inches near Snoqualmie.

Traction tires and chains are needed for mountain passes and traffic is slow.

Wenatchee Valley has a winter storm warning from 11 p.m. tonight until 10 a.m. Monday.

The Kittitas Valley has a winter weather advisory in effect from 11 p.m. tonight until 10 p.m. tomorrow night.

Most of the Cascades are subject to a winter weather advisory.

Snow levels will drop to around 1200 feet by Monday morning, primarily affecting the mountain passes.

The Yakima Valley could see a mix of rain and snow tomorrow morning as showers develop in the area with this second low coming in from British Columbia.

By lunchtime Sunday we will see showers in the Columbia Basin and the foothills of the Blue Mountains while a light dusting may begin to cover the peaks of the Blues themselves.

Not much buildup expected for lower elevations or Blues, if any.

Showers are expected to continue through Monday morning and begin to dry out late Monday evening/early Tuesday morning.

A cold front associated with this low will plunge us into much colder temperatures by Wednesday.

The front will pass and place us further into the jet stream, keeping us dry and cold from Wednesday, with daytime highs falling in the mid to low 30s, overnight lows becoming as cold as the upper teens !

Wednesday will see some sunshine before more clouds move in Wednesday evening. Thursday through Saturday will be mostly cloudy with a slight chance of a few showers on Veterans Day.
