Washington rain is already streaking across windshields in Seattle, and wet pavement will define the commute through much of the week.

Light to moderate rain continues this morning with temperatures hovering in the mid-40s. Highs reach only near 49 degrees today under thick clouds. According to the National Weather Service in Seattle, rain remains likely through Tuesday night, with additional rainfall totals between a tenth and a quarter inch at times.

Drivers along I-5, I-90, and Highway 99 should expect reduced visibility and standing water during heavier bursts. South winds around 7 to 10 mph keep conditions damp and chilly. Plan extra time for travel, especially during peak afternoon traffic.

Rain redevelops Tuesday afternoon and lingers into Wednesday. Highs stay in the upper 40s to near 50 degrees. By late week, temperatures dip into the mid-30s at night. A slight chance of rain and snow appears Friday, especially in heavier showers. While no major accumulation is expected in downtown Seattle, a rain-snow mix could briefly lower visibility. If skies partially clear and temperatures fall toward freezing, isolated slick spots may develop on elevated roadways.

The broader 6–10 day outlook signals a gradual moderation trend into early next week, though February remains unsettled for now.
