Bloomington hail storm history

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

Bloomington, located in Hennepin County, sits in a region where hail events occur with measurable frequency due to its position in the Twin Cities metropolitan corridor. The county's geography between major river systems and the urban heat island effect created by the metro area combine to produce favorable conditions for severe thunderstorm development during peak hail season.

Type of damage

How urgent?

Hail risk in Bloomington peaks during June and July, when the jet stream retreats northward and Gulf moisture extends into Minnesota, creating atmospheric instability. May and August represent secondary risk months. The metro's urban structure can locally enhance storm intensity, resulting in more frequent severe convection during these warm-season months compared to surrounding rural areas.
