During the late afternoon and evening of 4 April 2011, a fast moving and intense cold front moved southeast into a very warm, moist and unstable air mass over interior southeast Mississippi.  Immediately along and ahead of the cold front, a line of severe thunderstorms, already ongoing, moved into southeast Mississippi during the early evening and progressed across southern Alabama and the extreme western Florida Panhandle through midnight. While the main event outcome was widespread damaging straight-line wind gusts over the region, there was one rather long track EF-1 tornado that developed in association an isolated supercell thunderstorm which formed ahead of the squall line.
In total, there was one confirmed tornado and numerous reports of tree and power line damage.  Gusty southerly winds blowing ahead of the cold front in the afternoon were strong enough to blow down several trees during the daylight hours preceding the severe weather event.  There were no known deaths or injuries.
