Data source and limits
We use NOAA's MRMS radar product MESH (Maximum Estimated Size of Hail) for hail-size estimates. Each town's figure is the maximum inside its Census town limits. The percentage is the town area with estimates of at least 0.5 inch. A town's maximum isn't an estimate for every home. Each storm date covers one calendar day in Eastern time. A late-evening storm west of the Eastern time zone can appear under two dates. Radar estimates don't confirm hail on the ground or roof damage. Hail of 0.5 to 0.75 inch can damage roofs, especially older roofs. An estimate below 1 inch doesn't rule out damage. Read how we calculate sizes and times.
