Seattle weather: Few degrees cooler on Tuesday

A few clouds will be around to start Tuesday, but skies will give way to more afternoon sunshine.

The Brief

    • A G4 geomagnetic storm produced vivid Northern Lights across Washington on Monday; while the Kp index drops to 4 for Tuesday night, another display remains possible in dark, clear areas.
    • Freezing fog and frost will impact the Wednesday morning commute, with visibility below one mile and temperatures near 32°F creating slick conditions.
    • Washington's snowpack has dropped to about 50% of normal due to recent warm rains and dry spells, with no significant precipitation expected until the weekend.

SEATTLE - A severe geomagnetic storm last night led to a stunning display of the Northern Lights last night. While tonight's storm won't be as strong, there is another chance we could see the lights tonight in parts of our region.

Ski resorts still short on snow

After seeing a decent snowfall earlier, the recent rains and now prolonged dry stretch are impacting our snowpack. Many spots are seeing less than 50% snowpack right now. Unfortunately, the dry pattern will persist into part of the weekend.
