Windsor hail storm history

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

Windsor is located in Weld County on Colorado's Front Range, a corridor where afternoon convective storms tracking northeast from the Rocky Mountains create consistent hail risk. The county's geography and elevation make it a natural storm pathway during severe weather season, exposing residential and commercial properties to repeated hail damage over time.
