Bloomington hail storm history
Hennepin County·NOAA NCEI Storm Events Database·~75-day publication lag
Bloomington, located in Hennepin County, has experienced 20 documented hail events of at least 1 inch diameter over the past 10 years, with 7 classified as significant storms capable of functional roof damage. The city's position in the Twin Cities metropolitan area and proximity to major river systems creates favorable conditions for hail-producing thunderstorms during the regional convective season.
Hail risk in Bloomington peaks during June and July, when the jet stream retreats northward and Gulf moisture extends into Minnesota. Secondary activity occurs in May and August. The urban heat island effect of the Twin Cities metro can locally enhance storm intensity, increasing the likelihood of larger hail sizes during peak season months.
