Seattle is easing into a cool, mostly clear Sunday morning, with Boeing Field clocking in around 53°F, while mid and high clouds slide in ahead of a weak front. By this afternoon, those clouds should thin to give partly sunny skies and a high near 66°F, with inland spots likely running a few degrees warmer.

Afternoon Winds And Marine Conditions

Winds are expected to ramp up over the western Sound this afternoon and into the evening, and the Strait of Juan de Fuca will get gusty. A Small Craft Advisory is in effect from 11 a.m. today through 3 a.m. Monday for the central and east entrances, so operators of smaller boats will want to steer clear of exposed waters. Seas are generally around 4 to 6 feet but can turn noticeably choppier inside the advisory area, creating hazardous conditions for small vessels, according to the National Weather Service.

Sun Returns Monday, Tuesday Warms Up

High pressure builds back in on Monday, bringing mostly sunny skies and highs near 70°F. Tuesday is shaping up to be the warmest day of the week, with many neighborhoods expected to reach the upper 70s. There is only a slight chance of light rain late tonight and again around midweek, so most outdoor plans should stay dry, according to NWS Seattle.

What This Means For Your Plans

Drivers should not see much weather-related trouble on the roads this weekend, but ferry riders and anyone heading onto open water should keep an eye on the advisory and be ready for gusty conditions. Layers are your friend: expect cool mornings that gradually give way to sunnier, warmer afternoons through Tuesday.
