Mid day convection progressing over eastern NY has been producing severe hail reports.  Issued first warning based upon current reports as well as MRMS guidance. Image 1 below shows the reflectivity and the warning polygon, indicating the higher dBz indicative of the possible hail. Image 2 shows the MRMS guidance, with MESH values between 1 and 1.5 inches. Reports being received from the public were within this range. Probability of severe hail values had pixels between 70 and 90%. HSDA was having a bit more difficulty capturing the severe hail and even any hail development, with only rain being noted.
