Seattle is waking Wednesday to cloudy skies and temperatures near 48 degrees, with a wet day ahead. Showers are possible Wednesday, with a chance of thunderstorms late in the afternoon. The high should reach only about 53 degrees before temperatures slide back toward the low 50s.
Rain And Thunderstorms Arrive This Afternoon
Rain chances sit around 50% Wednesday, with south to southwesterly winds around 8 to 12 knots. The most unsettled stretch arrives during the afternoon, when a few thunderstorms could develop. Showers continue through the day and into the night, with temperatures dropping to around 41 degrees.
Cascades Face A Winter Weather Advisory
Seattle itself has no active weather alert in the supplied forecast, but a Winter Weather Advisory remains in effect for several Cascade zones through 5 p.m. Wednesday. The National Weather Service expects snow levels around 3,000 to 3,500 feet, with up to 6 inches of new snow possible around Mount Rainier. Drivers heading over the passes should check conditions before leaving, particularly during the afternoon.
Thursday Stays Damp Before Halloween Weekend
Thursday brings a 40% chance of rain, partly sunny breaks and a high near 52 degrees. Rain is likely again Friday, with a high around 51, before the pattern loosens Saturday: Halloween should be partly sunny, near 52 degrees, with only a small chance of rain. The improving weekend outlook is a notable update to the earlier Hoodline forecast.
Sunday through Tuesday looks quieter and a touch milder, with highs mostly in the mid-50s; Sunday and Monday should be partly sunny. For Seattle plans, the practical forecast is simple: keep a rain jacket close Wednesday and Thursday, expect slick roads during showers, and watch the sky during the afternoon thunderstorm window.
