A town's count uses hail inside the town's boundary box; a county's count uses the whole county, so rural counties with a lot of open ground rank high.
Free to cite with a link to this page. Figures are counts of local calendar days on which NEXRAD flagged at least one hail signature of one inch or larger.
Radar sizes are estimates from NEXRAD hail signatures (NOAA Severe Weather Data Inventory) for the largest stones in a storm cell, not a measurement at any one home. Ground reports are National Weather Service local storm reports and the NOAA Storm Events Database, as filed. Town-level data only; this page shows no addresses and no homeowner information.
