Westminster hail storm history
Adams County·NOAA NCEI Storm Events Database·~75-day publication lag
Westminster, located in Adams County on Colorado's Front Range, sits in a corridor where afternoon thunderstorms tracking northeast from the Rocky Mountains create conditions favorable for hail development. The city's elevation and proximity to mountain-driven convection patterns expose it to hail risk during the warm season, though the frequency of significant hail events remains relatively modest compared to areas further east on the plains.

Hail risk in Westminster peaks during May, June, and July, when afternoon convective storms are most common between 2 p.m. and 7 p.m. Mountain Time. Secondary risk occurs in April and August as spring and late-summer storm systems move through the Front Range corridor. Most damaging events, when they occur, develop during this May-to-July window rather than in winter or fall months.
