Tomer’s Take: Two pieces of energy will merge somewhere over UT/WY/CO 12/23-12/24. The timing and placement of the merger determines total snowfall for UT, WY, CO, NM.
My video forecast update:
Current Setup

Hello Chris,
Any insights on snow for southern ID? Sun Valley in need.
Thank you.
Hi Duncan – I hear you…unfortunately, I’m only forecasting light snow chances for Sun Valley late 12/22 into early 12/23 and light snow on 12/28. The pattern does look more active in JAN 2024. Chris
