Washington – Gray skies stretch over Seattle this morning as a steady line of Pacific moisture slides inland, coating streets and windshields in fine mist. The air feels heavy and raw—classic late-November weather that tests windshields, patience, and travel plans as millions prepare for Thanksgiving week journeys. By midday, light rain will strengthen into steady showers, bringing slick conditions on I-5, I-90, and regional connectors.
According to the National Weather Service, rain chances climb above 80% through Wednesday with highs near the upper 40s. South winds near 8 mph add to the chill, and damp commutes will dominate across King County. The heaviest rainfall arrives late Tuesday into Wednesday, with new precipitation totals reaching a quarter to half an inch in some areas.
To be fair, the Puget Sound region avoids major flooding this week, but colder air trailing Thursday’s storm hints at the first “winter tease” of the season. Highs near 51°F on Thanksgiving Day may dip toward the mid-30s by Saturday, raising a slight chance for a rain-snow mix in higher terrain and foothill communities. East of the Cascades, early travelers should stay alert for icy bridge decks and slushy mountain passes—especially late Friday and Saturday.
For now, umbrellas remain Seattle’s most valuable travel companion, and timing trips between showers will make the difference between a wet slog and a smooth arrival.
