WYOMING & COLORADO — A fast-moving Arctic cold front surged south through Cheyenne, Wyoming, and northern Colorado on Tuesday, causing temperatures to plunge into the teens within minutes while north winds gusted between 40 and 50 mph, producing dangerous wind chills and rapidly deteriorating conditions.
The frontal boundary is clearly visible on temperature and wind analysis, showing a sharp divide between sub-freezing Arctic air north of the front and much warmer air still lingering to the south.
Cheyenne Sees Rapid Temperature Collapse
As the cold front pushed through Cheyenne, temperatures fell sharply into the teens, confirming the arrival of a true Arctic air mass. Nearby locations north and west of Cheyenne quickly dropped into the single digits, while areas just south of the boundary remained significantly warmer for a short time.
This type of rapid temperature drop is typical of high-velocity Arctic fronts, where cold air surges southward faster than most weather systems.
Strong North Winds Intensify the Impact
Behind the front, north winds gusting 40–50 mph dramatically increased the severity of the cold. Even where air temperatures hovered in the teens or low 20s, wind chills plunged well below zero, making outdoor exposure dangerous…
