THANKSGIVING 2010 TORNADOES

Overview

A deepening low over the north central U.S. moved eastward over the Great Lakes during the morning of November 25. An associated cold front pushed southward through the Great Plains into southwest Louisiana. Conditions ahead of the front were only marginally suitable for the development of severe weather, with modest instability levels and weak wind shear aloft. Nevertheless, one thunderstorm developed that produced at least seven tornadoes across southwest and south central Louisiana. Dozens of homes were damaged or destroyed along a path from Jennings, Louisiana to near Opelousas, Louisiana, resulting in one injury. Five of these tornadoes were rated EF1 on the Enhanced Fujita Scale, with two rated EF0.
