Cheyenne, Wyoming – Snow begins stacking quickly across Wyoming’s high terrain as wind-driven flakes erase ridgelines and bury mountain roads. Conditions deteriorate fast once snowfall intensifies, leaving little room for error.
According to the National Weather Service in Cheyenne, a Winter Weather Advisory is in effect from 11 a.m. Wednesday through 11 a.m. Thursday for the Sierra Madre Range and Snowy Range. Snowfall rates may reach half an inch per hour, with total accumulations between 9 and 12 inches by Thursday. Wind gusts up to 40 mph will combine with falling snow to produce blowing and drifting, sharply reducing visibility.
The most dangerous conditions are expected from Wednesday afternoon through early Thursday. Travel across mountain passes near Centennial and throughout Albany County could become very difficult, especially during the Wednesday evening and Thursday morning commute windows. Whiteout conditions may develop suddenly as winds increase.
Snow-covered roads, drifting snow, and low visibility will create hazardous travel for anyone heading into the Snowy or Sierra Madre ranges. Even well-traveled routes can become impassable with little warning. Emergency officials urge drivers to avoid unnecessary travel during the advisory period.
If travel is unavoidable, slow down and carry winter survival supplies. Extra blankets, food, water, and a charged phone are strongly recommended. Visibility may drop below safe driving thresholds within minutes as snowfall intensifies and wind accelerates across exposed ridges.
Conditions improve gradually late Thursday morning as snowfall tapers and winds ease. No additional advisories have been issued yet, though officials caution that changing storm dynamics could prompt updates.
For the latest road conditions, drivers are urged to check Wyoming 511 before departing. Are you traveling through the Snowy Range or Sierra Madre Range Wednesday? Share what you’re seeing on the roads as conditions develop.
