Cheyenne Extended Forecast

Storm Tracker 5 Forecast Discussion

Forecast as of 8:00 AM on Monday, December 22nd

Monday: More snow and more wind on Monday. Blowing snow is the main concern as of now, as winds will be gusting up to 50 MPH, and while we expect only light snow accumulations across southeast Wyoming, blowing snow and winds will combine to create near whiteout conditions. If you are doing any holiday traveling on Monday, plan for extra time. Temperatures will be in the lower 30s, but wind chills will make it feel like it's in the teens for much of the day. Overnight, we could see a few more snowflakes, but snow should be coming to an end, winds will remain gusty with gusts up to 45 MPH overnight. Temperatures will fall down into the upper teens.

Tuesday: A ridge of high pressure will begin to push into the region for Tuesday and Wednesday, so we'll see more sunshine on Tuesday, but with a few clouds still lingering. Temperatures will remain on the cooler side of normal with highs on Tuesday in the low to mid 30s. We'll also continue to see strong winds out of the northwest at 20-30 MPH with gusts up to 40 MPH. Overnight, partly cloudy skies with cold temperatures in the low teens.

Wednesday: Mostly sunny skies for Wednesday, with temperatures rebounding to the warm side of normal in the lower 40s. Breezy winds will persist during the daytime and then during the overnight hours, a few clouds move in with mild lows in the upper 20s.

Snowfall Forecast: Light accumulations for much of the region, but mountain areas, especially northwestern facing slopes across the Snowy, Sierra Madre, and Laramie Ranges could receive upwards to 2 feet of snow.

Holiday Travel Forecast

Sunday - Monday: Snow showers and strong winds will affect travel between on I-80 between Cheyenne and Salt Lake City through Monday night. The threat of heavy snow between Laramie and Rawlins, especially near the mountains, and strong winds will limit visibility and make travel difficult. Periods of light snow and strong winds will affect I-25 from Denver to Casper.

Tuesday-Wednesday (Christmas Eve): This will be the driest period of the week and the best time to travel prior to Christmas. Skies will be partly cloudy with breezy winds which will cause areas of blowing and drifting snow. Winds will be stronger in the typical wind prone areas of SE Wyoming.

Christmas Day: While it remains 3 days out, models are suggesting that a storm system will bring more snow to the region beginning on Christmas Day. While the exact impacts are not yet clear, this storm could have significant affects on travel as snow increases from west to east on Christmas Day. If you are planing to do any traveling around Christmas, be sure to stay tuned for further updates.
