Radar estimates and reports are for anywhere inside the county's boundary. Radar estimates come from NOAA's MRMS estimated hail size (MESH), the largest hail the radar estimates aloft on a ~1 km grid. They often run larger than the hail that reached the ground, and they aren't an observation at any address. Reports are what people reported to the National Weather Service. Neither is proof of damage or an official record for an insurance claim. From NOAA's Storm Events Database (NCEI), which records tornadoes from 1950, hail and thunderstorm wind from 1955, and every kind of storm from 1996. A tornado that crossed county lines is counted in each county it touched. Recent months are added as NCEI publishes them, a few months behind. Damage is in the dollars of its year and is often an estimate.
