   NWS STORM PREDICTION CENTER NORMAN OK
   1111 PM CDT TUE MAR 13 2007
   
   AREAS AFFECTED...DEEP S TX
   
   CONCERNING...SEVERE POTENTIAL...WATCH UNLIKELY 
   
   VALID 140411Z - 140515Z
   
   STRONG STORMS WILL MOVE THROUGH THE NRN PARTS OF DEEP S TX INCLUDING
   PARTS OF JIM HOGG...BROOKS...AND KENEDY COUNTIES NEXT COUPLE HOURS.
   A WW WILL NOT BE NECESSARY UNLESS TRENDS BEGIN TO SUGGEST STORMS CAN
   DEVELOP FARTHER SWD THROUGH DEEP S TX.
   
   STORMS CONTINUE DEVELOPING ALONG TAIL END OF OUTFLOW BOUNDARY AND
   ARE MOVING ESEWD AT ABOUT 30 KT. WRN EXTENT OF DEVELOPMENT IS
   CLEARLY DEFINED OVER WEBB COUNTY AND CORRESPONDS TO A SHORTWAVE
   TROUGH ROTATING THROUGH BASE OF UPPER LOW. AS THIS FEATURE CONTINUES
   ENEWD...THE BOUNDARY LAYER FLOW ABOVE THE SURFACE SHOULD BEGIN TO
   VEER AND WEAKEN. THIS WILL GRADUALLY REDUCE THE SIZE OF THE LOW
   LEVEL HODOGRAPHS AS WELL AS LIMIT CONVERGENCE ALONG SEWD ADVANCING
   BOUNDARY. IN ADDITION...THE CAP IS STRONGER WITH SWD EXTENT INTO S
   TX. THIS SUGGESTS IT MAY BE DIFFICULT FOR STORMS TO BUILD MUCH
   FARTHER SWD THROUGH DEEP S TX. HOWEVER...STORMS ALONG SRN END OF THE
   BOUNDARY WILL POSE A SEVERE THREAT...AT LEAST OVER A LIMITED AREA OF
   DEEP S TX NEXT COUPLE HOURS.
