SEATTLE — The gray morning sky hangs heavy over Puget Sound, and by midweek, it’s set to spill again. The National Weather Service in Seattle says rain will intensify Thursday, marking the start of another wet December stretch across western Washington.
Light showers linger early this week, but a stronger Pacific system will push in Thursday morning, bringing steady rainfall through Friday. Totals may reach up to one inch in Seattle and higher in nearby foothills. Forecasters warn that urban flooding and slick roadways could affect I-5 and I-90 during peak commute hours.
Motorists should expect reduced visibility, standing water, and hydroplaning risks—especially on hilly or uneven surfaces. Plan extra travel time and keep headlights on during heavier bands. Though temperatures remain mild—mid-40s°F to low 50s°F—steady dampness and cool breezes will make it feel colder.
Rain chances ease briefly on Wednesday but return stronger late Thursday into Friday, with persistent drizzle and low clouds expected through the weekend. Snow will stay confined to higher Cascades passes, though winter drivers heading east of Snoqualmie or Stevens Pass should prepare for snow-covered roads and reduced traction.
Five-Day Local Outlook:
- Today: Cloudy, high 47°F.
- Wednesday: Mostly cloudy, high 45°F.
- Thursday: Rain likely, high 47°F.
- Friday: Rain continues, high 53°F.
- Saturday: Mostly cloudy, lingering drizzle, high 52°F.
