Plano hail storm history
Collin County·NOAA NCEI Storm Events Database·~75-day publication lag
Plano, located in Collin County, has experienced 13 documented hail events of 1 inch or larger over the past 10 years, with 8 of those storms producing hail 1.5 inches or larger. The city sits in the path of supercell thunderstorms that track northeast off the Llano Estacado, making hail damage a recurring concern for homeowners. The largest recorded hailstone in the area measured 2.25 inches in diameter, falling near Parker in March 2025.
Hail in Plano peaks during April, May, and June, with May representing the month when the largest-diameter hail most commonly occurs. Secondary hail activity extends into March and July. This seasonal concentration reflects the atmospheric conditions that develop when warm, moist air from the Gulf of Mexico collides with cold, dry air aloft during spring and early summer months.

Hail event counts for Plano rely on NOAA Storm Data and mPING crowdsourced reports, which depend on trained spotters and public submissions in the area. Smaller hail events (less than 1 inch) are underreported in official records, so actual storm frequency may be higher than the documented 1.3 events per year.
