While not in Tornado Alley, California averages about 10-15 days with severe hail annually, primarily during winter and spring frontal systems or summer monsoonal thunderstorms in the mountains and deserts. Notable events, like the October 2010 supercell in the Central Valley, have caused millions in agricultural and property damage. Peak hail activity often aligns with atmospheric river events or localized convective storms.
