Tornado in Jefferson Parish, Louisiana

Apparent tornado damage path in the marsh with discoloration of ground which matches up with area of rotation that tracked through this area. Tornado appears to have started over Lake Salvador and move onshore north of Barataria Blvd. Max width of the tornado and further extension of the path was supported by NDVI differencing.

A strong upper level trough ejected over the Southern Plains which caused rapid surface cyclogenesis to occur in southeast Texas. This surface low traversed across central and northern Louisiana. The rapid development of the surface low gave way to very high shear values, and with enough instability, a line of thunderstorms formed along its cold front. A couple of brief tornadoes occurred with the line in Pointe Coupee and Terrebonne Parishes. The Pointe Coupee Parish tornado resulted in 3 injuries. Otherwise, damaging wind gusts were noted with the line due to the extreme shear. The line exited southeast Louisiana in the early morning hours of the 25th.
