Denver hail storm history

Denver County·NOAA NCEI Storm Events Database·~75-day publication lag

Denver County sits on the Colorado Front Range, where afternoon convective storms tracking northeast from the Rocky Mountains create a corridor of elevated hail risk. The city's location at the base of the Front Range places it in the path of storms that develop over higher terrain and move across the metropolitan area, making hail a recurring weather hazard for homeowners.
