Seattle, WA – After a series of crisp, sunny fall days, Seattle and much of western Washington are bracing for a return to soggy weather as steady rain and overcast skies are set to move in by late Thursday. A frontal system from the Pacific is bringing wet conditions, cooler air, and potentially disrupted travel plans through the weekend. For many Seattle residents, this marks the start of a typical mid-October weather shift, signaling the beginning of the region’s wet season.
Rain Expected to Start Thursday Night, Lasting Through Saturday
According to the National Weather Service in Seattle, a frontal system moving into the region late Thursday night will bring widespread rain and occasional breezes across King, Snohomish, and Pierce Counties. Rain chances increase to 70% by Thursday night, with showers continuing into Friday. Heavy rain is expected to persist throughout Saturday, which will lead to potentially slick roads and longer travel times for those on their way to work or weekend events.
Travelers along major highways such as I-5, I-90, and SR-520 should prepare for slick pavement, reduced visibility, and longer commutes during the late morning and evening rush hours. In addition to the rain, localized gusts of wind up to 15 mph may accompany heavier rain bands, but overall, the winds are expected to remain manageable. Those heading out to local parks or fall events, such as pumpkin patch visits, should expect muddy fields and pack rain gear for outdoor activities.
Rainfall Totals and Temperatures for the Weekend
The Seattle metro area could see up to a half-inch of rain by Friday morning, while the Cascade foothills may receive more significant rainfall amounts. Despite the rain, temperatures will remain relatively moderate, with highs near 60°F and lows in the upper 40s throughout the weekend. Forecasters predict that rain totals in some areas could exceed half an inch before the weather begins to clear on Sunday.
Sunday’s Forecast: Light Showers and a Brief Break in the Clouds
On Sunday, a brief clearing is expected, with light showers before a weak front moves in early next week. While Sunday’s rain may not be as intense as the earlier part of the weekend, residents should still be prepared for occasional damp conditions. It’s important to note that Sunday’s highs will hover around 58°F, with lows near 47°F. While not as intense, Sunday’s weather could affect anyone with plans to get outside, so keep an umbrella or rain jacket handy.
Seasonal Change Brings Classic PNW Fall Weather
While this wet stretch of weather is characteristic of the Pacific Northwest’s fall season, it serves as a reminder that Seattle’s wet season has officially returned. Rain is expected to continue in the coming weeks, with more wet days likely throughout October and November. Whether you’re planning a day of outdoor activities, running errands, or commuting, be sure to keep your umbrella close, as Seattle’s iconic fall rain is here to stay.
