   NWS Storm Prediction Center Norman OK
   1138 PM CST Wed Dec 06 2017

   Valid 071200Z - 081200Z

   ...NO THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   The risk for thunderstorms appears negligible across the U.S. today
   and tonight.

   ...DISCUSSION...
   An upper-level trough from the southern Rockies northeastward to the
   Great Lakes will move southeastward today as west to southwest
   mid-level flow remains over the Southeast and along the eastern
   Seaboard. At the surface, high pressure will dominate across most of
   the CONUS keeping a dry airmass in place. For this reason, no
   thunderstorm activity is expected across the U.S. today or tonight.
