Centennial hail storm history

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

Centennial, located in Arapahoe County on Colorado's Front Range, sits in a corridor where afternoon convective storms tracking northeast from the Rocky Mountains create persistent hail risk. The combination of Front Range geography and the city's elevation exposes residential and commercial properties to repeated hail damage cycles during the late spring and summer months.

How urgent?

Hail risk in Centennial peaks between May and July, when atmospheric conditions favor the development of severe thunderstorms in the afternoon and early evening hours between 2 p.m. and 7 p.m. Mountain Time. April and August represent secondary risk periods. Most significant hail events in this region occur during the May-through-July window, though hail can occur outside these months.
