Eastern Pittsylvania County Severe Thunderstorm Warning - Prob Severe Jump Slow With Cirrus Canopy

I issued a Severe Thunderstorm Warning for Eastern Pittsylvania County (and others) at 2209 UTC, due to a combination of increasing high reflectivity aloft via all tilts, and a quick jump in Prob Severe model values. These values increased from 11% and 52% (two cells within a cluster of cells) at 2159 UTC to 88% (all cells in cluster) at 2201 UTC. There was a 4 sigma lightning jump with that storm as well at 2202 UTC. There was a delayed report of 1.00" hail at 2145 UTC in Pittsylvania County. There was also 1.00" hail at 2205 UTC in that county. Perhaps issuing the warning right after the jump in Prob Severe may have lead to lead time on the second 1.00" hail report. JJW
