Near-record warmth gives way to cooler, wetter weather and mountain snow. Idaho’s unusually mild November weather will continue through Friday, but a major pattern change will bring cooler temperatures, periods of valley rain, and accumulating snow to the mountains.
Afternoon temperatures will climb well into the 60s across many valleys Thursday and Friday. Boise could reach 70 degrees Thursday, putting the city within reach of the daily record. Twin Falls will also remain exceptionally mild, while temperatures in McCall reach the upper 50s.
The ridge responsible for the warmth will begin moving east Friday as a Pacific storm approaches the Northwest. That system will push a cold front through eastern Oregon Friday evening and western Idaho between midnight and 6 a.m. Saturday.
