Eastern Botetourt County Severe Thunderstorm Warning - Prob Severe Steadily Increases.

I issued a Severe Thunderstorm Warning for Eastern Botetourt County (and others), due to a combination of a 1.00" hail report at 2136 UTC, as well as increasing high reflectivity aloft with all tilts and steadily increasing values of Prob Severe. The Prob Severe values gradually increased through the 70s and 80s percent range in the time leading up to the warning (2146 UTC). The storm continues to increase in strength. Update: 1.00" hail in Rockbridge County at 2200 UTC. JJW
