Meteorological data collected across North America and temperate regions indicates that severe hail events peak most frequently during the spring and early summer months, specifically May and June. During this seasonal transition period, the atmosphere experiences high instability driven by warm, moist air masses clashing violently with lingering cold upper-level air fronts. These dynamic thermal contrasts create the towering supercell thunderstorms and powerful updrafts necessary to generate and support large hailstones across the central plains.
