   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   While severe storms are not expected, thunderstorms remain possible
   this Thanksgiving Day mostly across south/east parts of Texas.

   ...Synopsis/Discussion...
   A progressive semi-amplified belt of westerlies will prevail over
   the CONUS, while a closed southern-stream low becomes increasingly
   cut-off over Baja. As a cold front continues southeastward,
   thunderstorm potential across parts of Texas into Louisiana will
   further diminish and be increasingly confined to near-coastal/Deep
   South Texas through the afternoon, and focused offshore over the
   western Gulf of Mexico by tonight. Factors such as weak lapse rates
   and weak low/mid-level winds within the warm sector and near the
   front suggest that severe storms are unlikely today.
