Source and method
NOAA Storm Prediction Center preliminary local storm reports of hail 1 inch or larger, Jan 1, 2025 to Oct 26, 2026 (updated Oct 27, 2026). Dates are SPC storm days, which run from 12:00 UTC to 12:00 UTC (about 7 a.m. to 7 a.m. Central), so a late-night storm appears on the day it started. Reports come from spotters, the public and NWS offices: they can be revised, and a storm nobody reported is missing. SPC storm reports.
