   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 245
   CONTINUES.
   
   THREAT FOR ISOLATED DAMAGING WIND AND HAIL WILL PERSIST NEXT COUPLE
   HOURS WITH STORMS MOVING THROUGH SERN OK AND EVENTUALLY INTO SWRN
   AR. STORMS MAY EVENTUALLY DEVELOP A LITTLE FARTHER SWD INTO A
   PORTION OF NERN TX.
   
   SRN END OF MCS WITH BOW ECHO SIGNATURE CONTINUES MOVING THROUGH SERN
   OK AT AROUND 40 KT. ACTIVITY IS SUPPORTED IN PART BY A SLY LOW LEVEL
   JET THAT IS MAINTAINING LIFT AND DESTABILIZATION NORTH OF A WARM
   FRONT THAT STRETCHES FROM NRN LA THROUGH NRN TX. THE BOUNDARY LAYER
   IS SLOWLY WARMING DOWNSTREAM FROM THE LINE WITH TEMPERATURES NOW IN
   THE UPPER 60S TO AROUND 70...WHICH WILL INCREASE THE CHANCE FOR
   STRONGER WIND GUSTS TO REACH THE SURFACE. THE SPECIAL 19Z RAOB FROM
   FORT WORTH INDICATED A PRONOUNCED CAP BETWEEN 850 AND 700 MB. SRN
   END OF THE LINE MAY CONTINUE TO STRUGGLE TO DEVELOP SWD DUE TO
   PRESENCE OF A STRONGER CAP IN N CNTRL AND NERN TX. HOWEVER...STORMS
   WILL LIKELY CONTINUE EWD INTO SRN AR TOWARD EVENING.
