Snow forecast through end of November

Tomer’s Take: The next western storm system hits 11/22-11/25 in MT, UT, WY, CO, and NM. It delivers much colder air and higher snow ratios. Then, the pattern shifts with a much drier stretch through 11/30 and high pressure ridging. Stormier pattern might develop on/after 12/1 as jet stream resets.

Snow continues today across the higher elevations of VT, NH, and ME.

My forecast video:

You can see the problem at Jackson Hole, 11/22 @7am. The snow line is halfway up the mountain. We need colder air to drop the rain/snow line down to the valley floor. The next cold front will do just that with much colder air on/after 11/23.

Current Setup

Water vapor satellite shows the lurking Canadian cold front. It dives south through MT on 11/22.

Orange/red = drier air aloft.

Forecast Jet Stream

Drier period 11/26-11/30 with high pressure ridging. Pattern turns stormier on/after 12/1 as jet resets.
