Washington – A cold, damp chill hangs over Seattle this morning as temperatures sit near 36°F, with mist and light moisture clinging to roads and windshields. Drivers along I-5 and I-90 are already seeing reduced visibility in pockets, especially near low-lying areas and waterways.

According to the National Weather Service, skies gradually clear today with sunshine pushing highs near 50°F, offering a brief break before the next system arrives. Clouds rebuild Tuesday, and a 20% chance of light rain develops late in the day before steadier rain takes hold by Wednesday.

Rain becomes widespread Wednesday with a 90% chance and temperatures holding near 50°F. Periods of steady rainfall could drop between a tenth and a quarter inch, enough to create ponding on roads and slower commutes across Seattle, Bellevue, and Tacoma. Plan extra travel time and keep headlights on during heavier showers.

By Wednesday night, rain continues before tapering into lighter showers Thursday. Roads may remain slick during the morning drive, especially on bridges and elevated surfaces where moisture lingers longer. Keep a jacket handy and watch for sudden slowdowns.

Conditions improve heading into Friday with partial sunshine and highs climbing into the upper 50s. The first weekend of April trends drier and milder, with temperatures reaching near 60°F, signaling a gradual shift toward more stable spring weather.

For now, the key window for impacts centers on Wednesday’s steady rain and lingering showers into Thursday. Stay alert for changing road conditions and plan ahead for wet travel.
