How we counted

Counts come from NOAA hail reports since 2015. A hail day is a date with at least one report in the state. Official report times are already local. Recent Storm Prediction Center reports are converted from UTC to Central time. More reports come from populated areas, because more people are there to report hail, so this is not a measure of risk.
