Detailed Forecast

First Alert Weather

Intense inversions remain in place over our skies thanks to a very strong area of high pressure dominating the West. For us that means that the mountains can expect lots of sunshine and blue-bird skies with cold temps at night and warm temps during the day. Dense fog & stratus clouds will likely linger across the Snake River Plain and some valleys keeping temps a bit cooler.

Tuesday, strong inversions meaning warm and sunny in the mountains with temps in the 40's. Areas of fog and stratus layer keeping the Snake River Plain pretty gray with highs into the 30's.

Tonight, partly cloudy this evening with fog quickly forming again after sunset. Clear and cold in the mountains with lows in the single digits. The rest of us will fall into the 10's and 20's.

Wednesday, areas of dense morning fog giving way to some partly cloudy skies later in the afternoon. Still holding on to sunny skies for the mountains. Highs in the 40's for the high country with temps in the 30's for the valleys.
