Bloomington hail storm history
Monroe County·NOAA NCEI Storm Events Database·~75-day publication lag
Monroe County, home to Bloomington, has experienced 1 documented hail event of 1 inch or larger over the past 10 years. Bloomington's location in southern Indiana places it at the boundary between Great Plains and Appalachian weather systems, resulting in variable hail activity compared to counties further north.
Hail in Bloomington occurs most frequently during April, May, and June, when spring storm systems tracking northeast create conditions favorable for hail development. Secondary hail risk exists in March and July. The largest recorded hail event in Monroe County was 1 inch, occurring on November 18, 2025, which represents a marginal damage threshold capable of producing granule loss on aging roof shingles.

Monroe County's low hail event frequency reflects both its geographic location and NOAA's reporting density, which varies by county based on population and weather station distribution. The single documented 1-inch event over 10 years represents the available NOAA Storm Events Database record for this area. Current-year data is excluded from the annual frequency table until October, when NOAA's Storm Events Database has processed the full hail season accounting for the standard 75-day reporting lag.
