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.
