   AFTERNOON. AREA IS BEING MONITORED FOR A POSSIBLE WW. 
   
   THUNDERSTORMS HAVE BEGUN TO INCREASE ALONG A DRYLINE EXTENDING
   THROUGH THE TX PANHANDLE...THEN SWWD INTO ERN NM AND FAR WRN TX. A
   WEAK VORT MAX ORIGINATING OVER NRN MEXICO THAT TRAVERSED AROUND THE
   WRN PERIPHERY OF THE SUBTROPICAL RIDGE APPEARS TO BE PROVIDING
   FAVORABLE ASCENT/LIFT WHILE ANOTHER VORT MAX IS APPROACHING FAR WRN
   TX. UPPER ASCENT/LIFT IN COMBINATION WITH CONVERGENCE ALONG THE
   DRYLINE AND MODERATE INSTABILITY WILL SUPPORT RENEWED DEVELOPMENT.
   MID LEVEL MOISTURE REMAINS FAVORABLE...WHILE DRY LOW
   LEVELS/INVERTED-V PROFILES WILL LEAD TO A PRIMARY THREAT OF DMGG
   WINDS AS EVAPORATIONAL COOLING ENHANCES DOWNDRAFTS.
