Seattle traded its stretch of sunshine for a classic marine layer Thursday morning, with Boeing Field starting the day around 57°F and a light southerly breeze. The cool onshore flow is knocking afternoon highs back into the upper 60s after more than a week of warmth, with only a slight shot at some spotty evening drizzle across the lowlands.
Rain Moves In Friday
A frontal system is set to roll in Friday, with rain likely before 10 a.m. and a follow-up of showers and scattered thunderstorms through the afternoon. Highs will drop into the mid-60s, and south-southwest winds could gust near 20 to 25 mph in more exposed spots. New rainfall totals across the city are expected to stay light at generally less than a tenth of an inch, according to the National Weather Service Seattle.
How Your Commute Could Be Affected
Friday’s morning drive is shaping up to be a wet one. Roads will be slick, and any heavier bursts of rain could briefly cut visibility and create standing water in the usual low spots. Plan on slower travel, build in extra time, and have the rain gear within arm’s reach if you are walking, biking, or waiting for transit.
Boaters and Ferry Riders
A Small Craft Advisory is in effect for portions of the northern waters through mid-morning, and seas offshore may build to 8 to 10 feet later in the week, so small-boat operators should use extra caution, according to the National Weather Service Seattle. Ferry riders should keep an eye on operator alerts and give themselves some wiggle room in case of weather-related delays.
Weekend Outlook
Cool, unsettled weather hangs on into Saturday with more chances for showers and highs stuck in the mid-60s. Sunday looks only a bit drier, and the cool, showery pattern is expected to linger into early next week before temperatures gradually head back toward more typical July levels later in the month.
