Broken Arrow hail storm history
Tulsa County·NOAA NCEI Storm Events Database·~75-day publication lag
Broken Arrow, located in Tulsa County, sits in a region where the Ozark Plateau's elevation and moisture from the Gulf of Mexico converge to create favorable conditions for severe thunderstorms and hail. This geographic setting makes eastern Oklahoma a corridor for organized supercells capable of producing hail at or above damage thresholds. The frequency and intensity of hail events in this area reflect these regional weather patterns.
Check if your roof was damaged by recent hail
Hail in Broken Arrow follows a pronounced seasonal cycle, with April, May, and June representing the peak months for hail-producing thunderstorms. March and July also see elevated hail activity, though at lower frequency than the spring peak. During these months, atmospheric conditions—including wind shear and instability—favor the development of supercells that can produce hail stones large enough to damage roofs, siding, and vehicles.
