Washington’s brief burst of blue sky is fading fast, and clouds are thickening over downtown Seattle as pavement dries from an earlier chill. Temperatures have climbed into the upper 30s and will reach near 58 degrees this afternoon. Enjoy the partial sunshine now. Rain is lining up behind it.
According to the National Weather Service in Seattle, increasing clouds arrive after 4 a.m., with rain developing mainly after midmorning Tuesday. Highs settle near 53 degrees, and south winds increase to 8 to 10 mph. Rain chances jump to 90 percent Tuesday and 100 percent Tuesday night, with new precipitation amounts up to a tenth of an inch, then a quarter inch possible by Wednesday.
The steady pattern continues midweek. Wednesday holds near 53 degrees with rain and light south winds. By Wednesday night, rain remains likely as lows dip into the lower 40s. Thursday stays damp and cooler, with highs near 49.
Drivers along I-5, I-90 and Highway 99 should plan for slick stretches during heavier bursts. Allow extra braking distance through the Tuesday and Wednesday commutes. While afternoon temperatures remain well above freezing, early morning lows in the 30s mean isolated slick spots are possible on elevated ramps if skies briefly clear.
Clocks spring ahead at 2 a.m. Sunday, March 8. Daylight is increasing quickly, even as gray skies dominate this week.
Longer-range signals hint at gradual moderation into the 6–10 day window, with temperatures trending closer to seasonal norms. For now, keep rain gear handy. How wet are roads in your neighborhood today?
