Brighton hail storm history

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

Brighton sits in Adams County on Colorado's Front Range, where afternoon thunderstorms tracking northeast from the Rocky Mountains create consistent hail risk during spring and early summer. The terrain and atmospheric conditions in this corridor make Adams County a repeat target for severe convective hail events.

Type of damage

How urgent?

Hail risk in Brighton peaks from May through July, when afternoon storms between 2 p.m. and 7 p.m. MT most frequently develop along the Front Range. April and August represent secondary risk months when severe storms still occur but with lower frequency. The geographic position of Brighton—east of the foothills but still within the collision zone of mountain and plains air masses—concentrates this seasonal pattern.
