An arctic cold front moved across the region during the evening hours on Thanksgiving Day - November 25. Despite a very strong cap in place at 700 mb ahead of the front, several isolated showers formed across southeast Texas and southern Louisiana. Abundant low level wind shear below the cap allowed a few of these showers to develop low level mesocyclones. These showers rarely exceeded 30000 feet in height, and no lightning was ever detected with this activity.
One rotating shower that formed in the Gulf of Mexico south of Cameron moved onshore near Grand Chenier, then continued northeast across eastern Cameron, Jeff Davis, Acadia, and western St. Landry parishes. At least 7 tornadoes occurred along a line from Jennings to Lawtell, damaging as many as 50 homes and other buildings and causing 1 minor injury. Other tornadoes possibly occurred further to the southwest between Grand Chenier and Jennings, but caused no known damage in this region of marshes and crawfish ponds.
