Seattle weather: rain expected all work week

FOX 13 meteorologist Ilona McCauley has your seven day forecast.

The Brief

    • Western Washington will start the work week with cool, wet conditions and temperatures roughly 10 degrees below average, bringing heavy snow to the Cascades and several winter weather alerts to the mountain passes.
    • While the mountains face significant accumulation and difficult driving conditions, the lowlands will primarily see rain with the potential for brief, isolated snow mixes during overnight and early morning hours.
    • Residents should prepare for an active and windy week, particularly on Wednesday, with a continued chance of minor slushy accumulations on grassy surfaces through the coming days.

SEATTLE - The work week will start cool and wet around Western Washington.   A convergence zone will bring heavy snow at times to Stevens Pass on Monday morning.  For the lowlands, precipitation will mainly fall as rain, but overnight and early morning temperatures could occasionally dip just low enough for a brief rain-snow mix. Any mix would likely be isolated and short-lived, with little to no accumulation expected. In the heaviest showers, there could be a light coating on grassy surfaces or patio furniture this week, and a few slick spots can’t be ruled out. 

Forecast clouds, rain and snow around Western Washington early Monday morning.

A convergence zone will bring rain to parts of Snohomish and King County with snow along Stevens Pass. 

With the rounds of snow forecast this week to be heavy at times with gusty winds, several winter weather alerts are in effect for different parts of the Cascades at various times and days.  Snow is forecast almost every day this week, so please continue to monitor the road conditions and be prepared for winter driving conditions. 

Winter Storm Warning for parts of the Cascades.

Rounds of heavy snow, especially over Stevens Pass is possible.

A Winter Storm Watch for the Cascades and Hurricane Ridge.

Heavy snow and gusty winds will make travel difficult in the passes. 

Monday will be cool, breezy and wet.  In the wake of Sunday's front, afternoon highs on Monday will only be in the low to mid 40s.  These afternoon highs will be about 10 degrees cooler than average. In fact, much of the week is forecast for cooler than normal days. 

Forecast highs around the region on Monday.

A cool and wet day around the area on Monday. 

With temperatures trending cooler during the upcoming work week, we’ll be watching for those occasional lowland rain-snow mix scenarios during the overnight and early morning hours.  Wednesday is forecast to be quite active with wet and windy conditions.

Breezy, cool and wet this week with spotty wintry mix possible in the lowlands.
