Adams County·NOAA NCEI Storm Events Database·~75-day publication lag
Westminster, located in Adams County on Colorado's Front Range, has experienced no hail events of 1 inch or larger over the past 10 years according to NOAA records. The city's largest recorded hailstone reached 0.75 inches in diameter. Westminster's geography—positioned where afternoon convective storms track northeast from the Rocky Mountains—creates conditions for hail development, though significant events remain uncommon in this specific location.
Hail risk in Westminster peaks during May, June, and July, with secondary activity in April and August. Most storms capable of producing hail occur between 2 p.m. and 7 p.m. Mountain Time when afternoon heating destabilizes the atmosphere along the Front Range. Even during peak months, the probability of damaging hail striking any individual property remains low based on the 10-year historical record.
