November 2025 was one of the warmest on record across Western Wyoming & Eastern Idaho. Some locations did break records. In Jackson, WY, temperatures were 8º above normal in November, and snow & precipitation were well below avg in the mountains and the valley.

The first half of November has been incredibly warm across the West. Some ski areas are already delaying their openings due to a lack of natural snowfall, along with poor snowmaking conditions.

Active week of severe weather ahead...

Tornado today north of Akron, CO

I’m expecting the JH Valley, including the town of Jackson & Snow King, to see heavy snow on Thursday night in addition to the Tetons due to favorable SSW winds to minimize the shadow effect of the Tetons & due to strong synoptic scale forcing by way of warm air advection.
