   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe storms are not expected through tonight.

   ...Synopsis/Forecast...
   Upper heights will tend to rise through tonight east of the Rockies,
   while an upper low will continue to move inland over OR and northern
   CA through tonight, influencing the potential for at least a few
   thunderstorms across the region.

   Along/south of a residual front, a couple of stronger pulse-type
   storms could occur this afternoon across the coastal Southeast
   States including areas such as far southern SC and eastern/southern
   GA. However, an organized/sustained severe risk is unlikely.
   Elsewhere, isolated elevated thunderstorms may develop across parts
   of the Corn Belt, driven by low-level warm advection.
