Hail and Damaging Winds in Arkansas, July 4 to 5, 2011
A weakening, nearly stationary front helped to trigger thunderstorms in northern Arkansas during the morning hours of July 4th and 5th. As outflow boundaries (cool air flowing out of the thunderstorms, forming a boundary much like a mini-cold front) moved out away from these storms, new storms developed during the afternoon and early evening farther south.
