Clear skies and a chilly 39°F at Boeing Field are giving Seattle a calm start this Tuesday, but it is the kind of calm that does not stick around. Expect a mostly dry, partly sunny day with highs near 56°F, before a Pacific front moves in late Tuesday night into Wednesday, April 1, 2026, bringing steadier rain and a noticeable uptick in wind.
What Arrives And When
Rain is expected to develop after midnight between Tuesday, March 31, 2026, and Wednesday, April 1, 2026, then turn more persistent Wednesday morning. Lowland areas could see roughly a quarter to a half inch of rain on Wednesday, with lighter amounts late Tuesday night, which means wet roads and slower commutes are likely.
A Gale Watch is in effect for the coastal waters and the East Entrance of the Strait of Juan de Fuca late Tuesday night into Wednesday morning. Coastal gusts could hit 35 to 45 mph, and seas may build to 9 to 11 feet, so anyone with water‑dependent plans will want to shift them earlier or hold off, according to the National Weather Service Seattle.
Mountain Passes And Road Safety
Snow levels on Wednesday will start near or below the mountain pass elevations, then rise to around 4,000 to 4,500 feet during the day before dropping back below pass levels by early Thursday. Current projections call for 4 to 8 inches of snow at the passes. Drivers could encounter chain or traction requirements and sluggish travel conditions, so it is a good idea to check the latest updates before heading out via the WSDOT.
Late‑Week Outlook
Once this midweek system moves through, a drier and warmer pattern is expected to build starting Friday, April 3, 2026, and into the following week. Temperatures should climb back into the mid‑50s by Friday and could reach the mid‑60s by Monday, April 6, 2026, setting up a stretch of more comfortable, mostly dry weather for outdoor plans.
