St. Paul hail storm history
Ramsey County·NOAA NCEI Storm Events Database·~75-day publication lag
St. Paul, located in Ramsey County, sits within the Twin Cities metropolitan area—a region shaped by two major river systems and an urban heat island effect that can locally intensify thunderstorms. Hail events in this corridor are driven by the seasonal northward retreat of the jet stream combined with moisture from the Gulf of Mexico, creating a predictable but variable hail season.

Hail season in St. Paul peaks during June and July, when atmospheric conditions most frequently favor severe thunderstorm development across Ramsey County. Secondary activity occurs in May and August. Storm systems that produce hail in this region typically develop in the afternoon and evening hours as surface heating and wind shear align favorably for organized convection.
