Snow totals over the past 24 hours ending Sat AM range from 17-27 inches above 8,000 ft and storm snow totals include 41" at JHMR's Rendezvous Bowl Plot and 26" at Targhee. Light to moderate snow will continue on Saturday on the backside of the storm before drying out on Sunday.
Short Term Forecast
What a storm! Snow totals over the past 24 hours include 25-27" at JHMR's upper mountain, 21" at mid-mountain, and 17" at Targhee. Two-day totals now range from two to three-and-a-half feet in the Tetons above 8,000 feet.
Here are the latest 48-hour totals as of Saturday AM:
- 41" - JHMR Rendezvous Bowl
- 37" - JHMR Raymer Plot
- 37" - Surprise Lake (GTNP)
- 33" - JHMR Mid-Mountain
- 26" - Grand Targhee
- 15" - JHMR Base Area
- 12" - Togwotee Pass
- 11" - Snow King
Forecast for Saturday:
Snow will continue throughout the day on Saturday and into Saturday evening, but snowfall rates will be lighter compared to Thursday night and Friday. I'm expecting another 3-6 inches to fall above 8,000 feet on Saturday-Saturday Night and another 1-2 inches in the valleys.
Winds will be lighter on Saturday out of the west/northwest at 10-15 mph with gusts to 20-30 mph. Temperatures will remain steady in the low teens at 9,000 feet and may eventually lower into the upper single digits as the day progresses.
Highs will reach the 20s in the valley but could fall below zero late Saturday night depending on when snow begins to taper off.
Forecast for Sunday:
Snow will likely be coming to and end prior to sunrise on Sunday. At this point, I'm expecting dry conditions with partial clearing on Sunday as moisture/energy associated with the storm moves south of the area.
The big story for Sunday is that arctic air will spill into the area, resulting in a very cold day at all elevations. Highs will struggle to get above zero at 9,000 feet and will only be in the single digits above zero in the valley. Bundle up if you plan to hit the slopes to catch leftovers from the storm.
Dry and cold conditions will prevail from Monday (Jan 30) to Thursday (Feb 2) with a strong inversion setting up. All elevations will be cold Monday-Tuesday, then we should see a nice warming trend (but not too warm) in the mountains on Wednesday and Thursday while frigid temperatures remain trapped in the valley.
The next active period looks to be February 3rd-7th with two storms possible. I think these are more likely to end up being weaker storms, but hopefully, we can pick up some decent totals over the course of a few days.
From February 8th and beyond, my confidence is low in how the pattern will evolve, but I do think the storm door will at least be open to some extent through mid-month.
Thanks so much for reading! Next update on Monday (Jan 30).
