   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   No thunderstorms are expected on Thursday.

   ...Synopsis...
   Strongly amplified upper pattern, characterized by western CONUS
   ridging and central/eastern CONUS troughing, will gradually shift
   eastward throughout the period, while maintaining significant
   amplification. At the surface, expansive high pressure will remain
   largely in place, extending from the Pacific Northwest
   eastward/southeastward to the MS Valley. Some showers are possible
   within the warm-air advection north of a decaying cold front, from
   south TX into southern GA and northern FL. However, limited
   instability and elevated nature to these showers will likely inhibit
   thunderstorm development. No thunderstorm activity is expected
   elsewhere across the CONUS.
