Stillwater hail storm history

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

Stillwater sits in Payne County at the convergence of Tornado Alley's three primary ingredients: the dryline, the jet stream, and Gulf moisture. This geographic alignment makes the region a breeding ground for some of North America's most intense supercell thunderstorms, which regularly produce hail capable of structural damage to homes and vehicles.

Type of damage

How urgent?

Hail season in Stillwater runs from March through July, with peak activity concentrated in April, May, and June. May historically produces the most damaging large-hail events in the region. The springtime collision of warm, moist air from the Gulf with cold, dry air from Canada creates the atmospheric instability required to generate severe hail-producing storms.
