Cheyenne hail storm history
Laramie County·NOAA NCEI Storm Events Database·~75-day publication lag
Cheyenne, located in Laramie County, sits at the northern edge of the Great Plains severe weather track and within the southeastern Wyoming hail corridor. The Laramie Range channels storm activity eastward, and the combination of moisture lifting off the plains with Rocky Mountain orographic forcing creates conditions favorable for hail development. Laramie County has a documented history of hail events capable of causing functional roof damage to residential and commercial properties.
Check if your roof was damaged by recent hail
Hail risk in Cheyenne peaks during June and July, when atmospheric conditions most frequently support severe thunderstorm development. May and August represent secondary risk months when hail probability on active storm days can exceed 10 percent. The seasonal window from May through early September defines the period when homeowners should maintain storm awareness and ensure roof inspection protocols are current.
