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 within 3 miles of its center. Nearby search areas can overlap. Each storm date covers one calendar day in Eastern time. 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.
