Giant Hail on Radar

Here is what very large hail (two inches or more) looks like on radar.



The orange oval is the area where hail was likely falling at 5:17pm EDT. The two orange arrows indicate a non-meteorological echo known as a "hail spike." There is no precipitation falling along the spike. It is an artifact of the way the radar senses the hail. Unfortunately, the Roanoke WSR-88D does not have dual-polarization as yet so I cannot show you what the hail would look like on that type of display.  


There is also a tornado warning (purple polygon) in effect on that storm. 


Update: Saturday, 9:15pm CDT. Via Facebook here is a photo of some of the hail from this storm.
