Seattle is serving up classic February whiplash on Tuesday, February 10, 2026. Clear skies and cool air sit over the city this morning, with early-morning stations clocking temperatures in the low 40s. The payoff later in the day looks decent: skies should clear to a sunny afternoon with a high near 53°F and light north-northeast breezes. The catch is the fog, which is pooling in the south Sound and river valleys and could make the morning commute a slow crawl.
Foggy Mornings, Sunny Afternoons
The National Weather Service has a Dense Fog Advisory in effect through 9 AM PST Tuesday, February 10, 2026 for the lowlands of Lewis and southern Thurston counties, the Middle Chehalis River Valley, Olympia, and southern Puget Sound. Forecasters warn that visibility could drop to a quarter mile or less, turning early drives into a bit of a guessing game, according to NWS Seattle.
What To Expect Today
Most neighborhoods should shake off the fog by mid to late morning, trading the gray for a sun-filled afternoon and a high around 53°F. Temperatures slip back into the upper 30s to low 40s overnight. Light north-northeast winds of 2 to 7 mph should make it a decent day to run errands, take a walk, or sneak in an outdoor lunch break. For context, fog choking the morning commute has already been an issue this week, so drivers in low-lying spots should be ready for visibility to change on a dime.
Weekend Outlook
Dry conditions are expected to hold through Thursday, but the next system looks set to roll in early Friday, February 13, 2026, bringing rain to the lowlands and fresh snow to the Cascades. Ensemble guidance points to a cooler turn by Sunday and Monday, which bumps up the odds that some overnight showers could mix with snow at lower elevations, according to NWS Seattle.
Quick Tips
If you are driving through the fog this morning, ease off the gas, use low-beam headlights, and give yourself extra room to stop. Check live traffic and transit updates before heading out so you are not surprised by delays. If your plans involve heading over the passes later this week, keep tabs on mountain conditions, which will trend more wintry as that next system moves in.
