(10/11) Frosty start to Tuesday, coldest morning of Fall

We’ll have a very nice Monday evening in store with mainly clear skies and light winds. This is the perfect scenario for a chilly night. There could be some patchy fog in the usual spots, especially down south but many more of us might have to scrape our windshields early Tuesday morning.

Morning lows Tuesday will be near freezing for areas in the south Sound and points south, as well as the east side of Pierce, King and Snohomish counties. Nearer the water like in Seattle, temperature will bottom out in the mid 30s.

Clouds increase and temperatures moderate through the day and by late afternoon a front will sweep in with rainfall. Snow levels in the mountains will be down to around 3,000 feet so a few inches of snow will fall at Stevens Pass late Tuesday afternoon and Tuesday evening. At Snoqualmie Pass, there could be some mix of rain and snow but probably no travel issues.

A few morning showers will give way to sunshine on Wednesday with highs in the 50s.

A generally-unsettled weather pattern brings chances of rain Thursday into the upcoming weekend with plenty of cloud cover. The heaviest rainfall looks to be around Saturday night and Sunday. The mountains could pick up more snow but amounts are uncertain at this time, as are any issues surrounding pass travel.
