Especially in a situation like this where we didn't have extremely violent updrafts producing huge stones that could survive a greater degree of melting. Though it's also true that Floyd County's higher elevation allowed more of the hail to make it than would have into the Roanoke Valley. Good point, Sirius.

The more important parameter is the height of 'wet bulb zero'...which in this case was ~8200' http://www.spc.noaa.gov/exper/soundings/09043000_OBS/ SSD Everything else being equal...an 11K freeze level is kinda high for hail to survive to the surface.
