   1030 AM CST Fri Nov 19 2021

   Valid 191630Z - 201200Z

   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   The risk for thunderstorms is negligible across most of the U.S.
   today through tonight.

   ...Florida...
   A moist environment to the south of a cold front will influence
   scattered showers and the possibility of isolated/occasional
   thunderstorms across the southern Florida Peninsula and Florida Keys
   vicinity today. Severe storms are unlikely given the weak lapse
   rates and limited low-level/deep-layer shear across the region.
