The best bets in Wyoming
The highest and northernmost stations in Wyoming have the best odds, and elevation does most of the work. The top four are Snake River, Lake Yellowstone, Old Faithful and Bondurant.
It depends on where. The best station of the 60 we track is Snake River at 100%, almost certain, and the typical station is 59%. The ZIP lookup above gives your own number.
NOAA counts at least 1 inch of snow on the ground on the morning of December 25. The odds here are the share of years from 1991 to 2020 that met that.
At the highest and northernmost stations: Snake River (100%), Lake Yellowstone (100%) and Old Faithful (100%). Elevation does most of the work, so a drive into the hills can change the odds a lot.
32% for 1 inch or more on the ground, 14% for 3 inches and 5% for 5 inches, at Cheyenne (6,128 feet).
2 of the last 10 Christmases with a report had at least 1 inch of snow on the ground at Cheyenne.
At Snake River, the odds of 5 inches or more are 100%. Most stations are lower; the state page table shows 1, 3 and 5 inch odds for each reference station.
Snake River had 44 inches on the ground on Christmas morning 2016, the deepest we see in the last 10 years.
From December 10, the ZIP lookup adds a forecast of the snow on the ground Christmas morning. It shifts from day to day until the last few days.
