   ...NO SEVERE THUNDERSTORM AREAS FORECAST...

   ...SUMMARY...
   Severe thunderstorms are not forecast across the contiguous United
   States today and tonight.

   ...OK/AR...
   Scattered thunderstorm activity has developed this morning over
   eastern OK, in a region of low-level warm advection and weak
   elevated CAPE (generally below 250 J/kg).  CAM guidance suggests
   this activity may persist for a few more hours and possibly moving
   into northwest AR before weakening.  

   Otherwise, the ongoing forecast is on track with no changes made.
