As of 5:40 a.m. PDT Friday, March 27, 2026, Seattle woke to clear skies and a chilly 39°F, a classic early-spring start for the city. Forecasters are calling for a mostly sunny day with afternoon highs near 55°F, and light north winds that will make waterfront neighborhoods feel a bit cooler. Skies are expected to turn mostly cloudy overnight Friday, with lows near 40°F, so evening plans should stay generally dry.
Afternoon Breeze Keeps Things Cool
North winds will stay on the light to moderate side, around 2 to 9 mph during the day, then nudging up to about 8 to 10 mph by late afternoon. That should keep most neighborhoods in the low 50s through mid-afternoon. Temperatures are only expected to dip a degree or two later in the day before thicker cloud cover moves in for the night.
Any patchy fog that formed along the lower Chehalis River is expected to burn off after sunrise and is unlikely to cause problems for most morning commutes.
Weekend Shift: Sunday Soaker On The Way
A Pacific trough moves in late Sunday, and rain is likely after 11 a.m. on Sunday, March 29, with highs near 52°F and about a 70% chance of precipitation. According to National Weather Service Seattle, new rainfall amounts should be light, generally less than a tenth of an inch for most lowland spots. However, the Puget Sound convergence zone could squeeze out locally heavier showers over King and northern Pierce counties. If you are planning to be outside Sunday afternoon, plan on an umbrella and a little extra travel time.
Mountains, Marine And Monday Commute
In the Cascades, forecasters expect 2 to 4 inches of new snow, with locally higher totals possible in the North Cascades. Lowland roads, however, should see little to no accumulation from the system.
The National Weather Service also highlights the potential for coastal and marine gusts to climb above 20 to 25 knots early Monday as a disorganized low slides through the region, so mariners are urged to keep an eye on updated forecasts. Shower activity should taper off Monday, offering a brief dry pause before another system arrives around midweek. That makes Sunday into Monday the stretch most likely to slow commutes.
