   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Organized severe storms are not expected across the U.S. mainland
   Friday.

   ...Discussion...

   A few elevated thunderstorms will be possible within a weak warm
   advection regime both Friday morning and again later Friday night
   primarily across OK into southeast KS. Other than a low-end risk for
   small to marginally severe hail, no severe weather is expected.

   Other thunderstorms are possible along a cold front, mainly across
   eastern NC during the day, but severe weather is unlikely.
