   ...NO SEVERE THUNDERSTORM AREAS FORECAST...   
      
   ...SUMMARY...   
   Severe thunderstorms are not forecast across the U.S. today or   
   tonight.   
      
   ...Synopsis and Discussion...   
   Large-scale upper troughing will persist today over the central and   
   eastern CONUS. An embedded mid-level shortwave trough will pivot   
   quickly east-northeastward across the Deep South and Atlantic   
   Seaboard through this evening as a secondary/reinforcing cold front   
   advances southeastward across the remainder of the central Gulf   
   Coast states and FL Peninsula. Low-topped convection ongoing this   
   morning over the east-central Gulf will struggle to attain   
   sufficient height to support charge separation and lightning as it   
   approaches the west-central FL Peninsula (Tampa vicinity),   
   especially given the poor lapse rates and multiple stable layers   
   aloft observed in the 12Z TBW sounding. Generally 60s surface   
   dewpoints are in place this morning ahead of the front across south   
   FL and the Keys. As daytime heating occurs, adequate instability   
   should develop to support isolated thunderstorms over these areas.   
   Low-level flow will veer through the afternoon with the approach of   
   the cold front, and greater thunderstorm potential should eventually   
   focus offshore. With poor lapse rates aloft limiting updraft   
   strength, severe thunderstorms are not expected.
