Mountain Weather

The Halloween weekend storm was the biggest of the season so far,  with the rain/snow line dropping to around 7,500 feet. The mountain picked up 6-10 inches of snow, with most accumulating above 8,000 feet.

The storm has moved east into Wyoming, and a quiet, mostly dry week follows. Leftover moisture from the storm will keep low clouds and patchy fog around in the valleys, including the Wood River Valley, tonight and Tuesday morning. Mountain temperatures will stay steady through Friday, with highs near or slightly below normal for early November. Expect valley highs in the 40s °F and overnight lows in the low 20s °F around Stanley and the mid-to-upper 20s °F near Ketchum. Two weak disturbances, one late Tuesday and another Thursday afternoon into Friday morning, will bring extra clouds and a slight chance of light mountain snow showers, though no significant accumulation is expected.

A stronger change arrives this weekend. High pressure builds directly over the region, bringing clear, dry weather and a steady warming trend. Temperatures should climb above normal by late in the weekend, with valley highs near 50°F, and the warmth will likely hold into early next week. No storms are expected through at least early next week.
