Snow Creating Travel Issues in the Northwest

30 Nov 2022, 6:25 pm

Heavy snow caused problems through the Seattle metro on Tuesday and we are expecting more wintry weather to arrive overnight into Thursday morning. 1-3″ of snow will be possible in the Seattle metro and surrounding areas with higher totals in the range of 5-8″ in the foothills. Be prepared for tough driving on I-90 and I-5. Additionally, the heavy nature of the snow in combination with gusty winds could cause downed trees and power lines.

Snow Threat

Another push of moisture brings in more heavy high-elevation snow to the Cascades Thursday. Winter weather alerts are in effect from Washington to Wyoming for the next rounds of heavy snow and gusty winds. Snow in the highest elevations could top 2-3 feet in some locations.

With heavy snow in the forecast, the avalanche risk has increased for the chimney of Idaho and western Montana Thursday, and in central Idaho through Friday. Backcountry activities are strongly discouraged and travel along I-90 may be impacted.

Rainfall Potential

In addition to snowfall, we will see the potential for heavy rain. The Weather Prediction Center (WPC) issued an excessive rainfall outlook for the Oregon and northern California coastlines on Wednesday. Through Thursday we could see locally up to 4″ of rainfall.

Timing

The next system arrives overnight. Higher elevations will see heavy snowfall and low visibility while lower elevations see a wintry mix, along with heavy rainfall. We will see rain and snow continue into Thursday before energy pushes into the Sierra Nevada and Rockies.

Another low and trough push onshore Thursday to keep the snowfall and coastal rainfall trend going. The first cold front moves into Wyoming at the same time.
