A soft mist clings to windshields across the Puget Sound this morning as Seattle wakes to a gray, motionless sky. The calm won’t last long — a Pacific system is on the move, promising to end November’s quiet spell with several rounds of steady rain through early Tuesday.
According to the National Weather Service in Seattle, light showers will begin to build Monday afternoon, increasing in coverage by evening. Expect rain chances around 70% Monday night, tapering slightly Tuesday morning as a weak low-pressure center pushes inland. Though rainfall totals remain light — generally less than a tenth of an inch per period — persistent drizzle and cloud cover will keep streets slick and commutes slow.
Drivers on I-5, I-405, and Route 520 should expect wet pavement and reduced visibility, especially during early morning and evening rush hours. Winds will stay light, but pooling water and patchy fog could impact travel times north toward Everett and south into Tacoma.
Temperatures will hold near 45°F for highs and mid-30s for lows, cold enough for occasional frost in outlying valleys if skies briefly clear. While snow isn’t in the cards for Seattle proper, colder air in the Cascades could dust higher passes, creating slick travel for anyone returning from holiday trips.
Five-Day Outlook (Seattle, WA):
- Monday: Cloudy, rain chance 30%, high 45°F, low 40°F.
- Tuesday: Rain likely early, mostly cloudy later, high 46°F, low 37°F.
