Erie hail storm history

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

Erie is located in Boulder County on Colorado's Front Range, a region where afternoon convective storms tracking northeast from the Rocky Mountains create consistent hail risk. The geography and elevation of this corridor make it particularly vulnerable to the development and persistence of severe thunderstorms during peak season.

Type of damage

How urgent?

Hail in Erie follows a distinct seasonal pattern, with the highest risk occurring between May and July. During these months, afternoon storms between 2 p.m. and 7 p.m. Mountain Time are most common, driven by heating along the Front Range. Secondary risk periods occur in April and August, though these months produce fewer significant events.
