   AREAS AFFECTED...PORTIONS OF ERN AR...WRN TN...NRN MS...NRN
   AL...NWRN GA

   CONCERNING...SEVERE THUNDERSTORM WATCH 239...240...

   VALID 061943Z - 062115Z

   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH
   239...240...CONTINUES.

   SUMMARY...THE RISK FOR SEVERE THUNDERSTORMS CONTINUES ACROSS WWS 239
   AND 240.

   DISCUSSION...EXTRAPOLATION OF AN ONGOING BOWING LINE SEGMENT WITH
   AROUND 35-40 KT OF FORWARD MOTION WILL LIKELY TAKE A DMGG-WIND RISK
   THROUGH NERN/E-CNTRL AR TOWARD THE MS RIVER DURING THE NEXT COUPLE
   OF HOURS. POSSIBLE DEVELOPMENT OF A BOOKEND VORTEX/MCV IS NOTED AT
   THE NRN EXTENT OF THIS LINE...WHICH MAY ENHANCE THE SVR-WIND RISK
   ACROSS FAR NERN AR...THOUGH INSTABILITY IS RELATIVELY MORE MARGINAL
   IN THESE AREAS. ELSEWHERE...SCATTERED TO NUMEROUS THUNDERSTORMS
   CONTINUE ACROSS PORTIONS OF THE DEEP SOUTH WHERE VERY STRONG
   INSTABILITY EXISTS AMIDST 30-40 KT OF EFFECTIVE BULK SHEAR.
   CONTINUED CONGLOMERATION OF COLD POOLS WILL LIKELY FOSTER AN
   INCREASE IN THE DMGG-WIND POTENTIAL AS THE PEAK OF THE DIURNAL
   HEATING CYCLE IS REACHED.
