Cheyenne, Wyoming – A Winter Storm Warning is in effect for portions of southeast Wyoming, where heavy mountain snowfall and strong winds are expected to create hazardous conditions from Wednesday morning through Thursday.
According to the National Weather Service in Cheyenne, winter weather advisories for the Sierra Madre and Snowy Ranges have been upgraded to warnings, effective 5 a.m. Wednesday through 11 a.m. Thursday. Forecast models indicate 12 to 20 inches of snow will be possible in the mountains, with locally higher totals near peak elevations.
In addition to heavy snowfall, wind gusts up to 50 miles per hour are expected, which could lead to blowing snow and sharply reduced visibility. These conditions may make travel extremely difficult and, at times, dangerous in higher terrain.
While snow accumulation outside of the mountains is expected to be minimal — generally a dusting or none at all — travel through mountain corridors and high-elevation roadways could become hazardous. Roads connected to mountain access routes, including segments near Wyoming Highway 130, Wyoming Highway 230, and backcountry routes west of Laramie and Saratoga, may see rapidly changing conditions.
The National Weather Service warns that outdoor recreation could become life-threatening during the warning period. Backcountry travel, snowmobiling, and mountain passes may be especially dangerous due to deep snow, strong winds, and low visibility.
Drivers planning travel through mountainous areas are urged to check road conditions, carry winter emergency supplies, and consider postponing trips until conditions improve. Visibility reductions may occur quickly during heavier snowfall bands.
This alert may be especially relevant for commuters, outdoor workers, and travelers using mountain routes during early morning or overnight hours.
Residents are advised to continue monitoring official National Weather Service updates as conditions evolve.
