Aurora hail storm history
Arapahoe County·NOAA NCEI Storm Events Database·~75-day publication lag
Aurora sits in Arapahoe County on the Colorado Front Range, where afternoon convective storms tracking northeast from the Rocky Mountains create consistent hail risk throughout the spring and summer months. This geographic position places the city in a corridor where conditions regularly favor hail development, particularly during the peak season from May through July.
Check if your roof was damaged by recent hail
Hail risk in Aurora peaks during May, June, and July, when afternoon storms between 2 p.m. and 7 p.m. MT are most frequent. Secondary risk occurs in April and August. The Front Range terrain accelerates storm development and channeling, concentrating hail-producing cells along this corridor during the warm season.
