Rochester has a history of severe weather, including a notable hailstorm in May 2022 that dropped golf-ball-sized hail across the city, causing widespread roof and vehicle damage. The peak season for severe thunderstorms in southeastern Minnesota typically runs from May through August, driven by warm, moist air from the Gulf of Mexico clashing with cooler northern fronts.
