   CONCERNING...SEVERE THUNDERSTORM WATCH 183...
   
   VALID 180623Z - 180800Z
   
   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 183
   CONTINUES.
   
   CONVECTIVE OUTFLOW CONTINUES TO GRADUALLY SAG SWD ACROSS SEVERE
   WW#183.  MUCH OF THE EARLIER THUNDERSTORM ACTIVITY HAS DECREASED IN
   INTENSITY EAST OF I-35...HOWEVER AN UPWARD EVOLVING MCS IS NOTED
   ALONG/JUST NORTH OF OUTFLOW FROM DIMMIT COUNTY...NWWD INTO NRN
   MEXICO SOUTH OF DRT.  IT APPEARS THE MCS MAY BE AIDED IN PART DUE TO
   A WEAK SHORTWAVE TROUGH LOCATED JUST UPSTREAM OF THIS DEEP
   CONVECTION.  LATEST THINKING IS THE MCS WILL CONTINUE ITS SEWD
   MOVEMENT ALONG THE RIO GRANDE VALLEY...ENHANCED BY A WEAK LLJ THAT
   SHOULD PROVIDE ADDITIONAL INFLOW FOR FORWARD PROPAGATING CLUSTERS. 
   MOVEMENT IS NOT PARTICULARLY FAST BUT ISOLATED SEVERE HAIL COULD
   ACCOMPANY AN OTHERWISE HEAVY RAIN-PRODUCING SYSTEM.
