Florence hail storm history
Fremont County·NOAA NCEI Storm Events Database·~75-day publication lag
Florence, located in Fremont County, experiences hail infrequently compared to other areas of Colorado. NOAA records document 1 hail event of 1 inch or larger over the past 10 years, with the largest recorded hailstone measuring 1.25 inches in diameter. Despite this relatively low frequency, Florence sits within the Eastern Plains hail corridor, one of North America's most active hail zones.
Hail risk in Florence peaks during May, June, and July, with secondary activity in April and August. Storms that produce hail typically track northeast from the Rocky Mountains with high frequency during the growing season, creating conditions where severe thunderstorms can develop rapidly across the plains. While Florence's recorded event count remains low, the underlying atmospheric setup during these months favors hail formation across the region.
