By 5:35 a.m. PDT Wednesday, April 1, 2026, central Seattle was already waking up to light rain and mist, with temperatures at Boeing Field sitting near 45°F. The soggy start is expected to hang on through the morning, with the afternoon high topping out around 50°F. Strengthening south winds will make it feel chillier and turn roads slick in spots, so plan on a slower commute and watch for low clouds and patchy fog in some neighborhoods.
Rain Timing And Totals
Steady rain is forecast to spread farther inland through the morning and continue through Wednesday, April 1, with the most persistent and heaviest showers expected from late morning into the afternoon. New rainfall totals are projected to range from a few tenths of an inch up to about three-quarters of an inch across interior areas, with roughly 0.5 to 1 inch along the coast. Coastal seas are already running high and gale warnings are posted for the outer waters, where rough surf will be an issue, according to the National Weather Service.
Winds, Marine And Mountain Impacts
In the lowlands, more exposed spots could see wind gusts in the 20 to 30 mph range, while the outer coast, Whidbey Island and parts of the San Juan Islands may contend with stronger 35 to 40 mph gusts. Mariners should be ready for choppy conditions and high seas through the morning.
Snow levels are expected to climb toward 4,000 to 4,500 feet by late morning, then drop below pass level tonight. That sets the stage for 4 to 8 inches of new snow at the passes late tonight into Thursday morning. Anyone planning mountain travel should check current road and pass conditions before heading out via WSDOT.
Looking Ahead
By Friday, April 3, a ridge of high pressure is expected to build over the region, bringing a drier and warmer pattern. Highs should reach the mid 50s on Friday, rise to near 60 on Saturday and climb into the mid 60s by Monday, April 6. A chance of light rain creeps back into the forecast by Tuesday, April 7, so if you are planning outdoor plans, the weekend is your best bet, with an eye on updated forecasts early next week.
