MARCH 27 2009 SEVERE WEATHER

 

Overview
The third day in a row of severe weather impacted Southeast Texas and Southwest Louisiana. Numerous multicell and supercell thunderstorms moving across the area spawned one confirmed tornado and widespread large hail. One intense supercell thunderstorm developed north of Houston, TX, and tracked for hundreds of miles across southeast Texas, through southwest Louisiana, into Mississippi, with dozens of reports of large hail received. This supercell thunderstorm produced hail up to grapefruit size in Allen Parish, which was the largest known hail in southwest Louisiana since 2003.
