Issued a severe thunderstorm warning for quarter sized hail for a storm that was moving out of Yadkin County NC and moving into Surry and Wilkes Counties. Started by analyzing storms with the suite of MRMS Data. We initially looked at the MESH product, which was indicating .25 in hail. Knowing that the storms had a history of producing quarters, we interrogated with the MRMS Height 50 dBZ echo Above -20 C. Noticing a lack of 50 dBz echos over -20C, we concluded that given the depth of the cold air under the cutoff low, severe hail was possible with lower cores than normally anticipated.
