   ...THERE IS A SLGT RISK OF SVR TSTMS FROM PARTS OF W TX THROUGH WRN
   OK...
   
   ...W TX THROUGH WRN/CNTRL OK...
   
   EARLY THIS EVENING A SURFACE FRONT EXTENDS FROM THE TRANSPECOS AREA
   OF SW TX NEWD THROUGH NCNTRL TX AND SERN OK. S OF THIS BOUNDARY RICH
   LOW LEVEL MOISTURE IS RETURNING NWD THROUGH THE WARM SECTOR WITH
   SURFACE DEWPOINTS AROUND 70 ALONG THE TX COAST TO MID 60S ACROSS
   CNTRL TX. HOWEVER...EVENING RAOB DATA SHOW THE EML HAS SPREAD EWD
   THROUGH THE SRN PLAINS...EFFECTIVELY CAPPING THE WARM SECTOR TO
   SURFACE BASED CONVECTION.
   
   LOW LEVEL JET IS FORECAST TO STRENGTHEN TONIGHT ACROSS TX DOWNSTREAM
   FROM SLOWLY EWD MOVING UPPER TROUGH NOW CENTERED OVER THE BAHA AREA.
   ASSOCIATED INCREASE IN THETA-E ADVECTION AND LIFT SHOULD RESULT IN
   NWD DESTABILIZATION AND CONVECTIVE DEVELOPMENT LATER TONIGHT MAINLY
   NW OF THE SURFACE BOUNDARY WHERE COOLER MID LEVEL TEMPERATURES EXIST
   AND THE CAP IS LESS PRONOUNCED. GIVEN COMBINATION OF STEEP MID LEVEL
   LAPSE RATES...MODERATE INSTABILITY AND SHEAR THROUGH THE CLOUD
   BEARING LAYER SUPPORTIVE OF SUPERCELLS...THREAT WILL EXIST FOR
   SEVERE STORMS LATER THIS EVENING AND OVERNIGHT. WITH CAP IN PLACE
   OVER THE WARM SECTOR...MOST OF THE STORMS SHOULD BE ELEVATED NW OF
   THE SURFACE FRONT SUGGESTING LARGE HAIL SHOULD BE THE MAIN THREAT.
   HOWEVER...ANY STORMS THAT CAN DEVELOP NEAR OR ON THE SURFACE
   BOUNDARY MAY BE CLOSE ENOUGH TO SURFACE BASED TO SUPPORT SOME THREAT
   FOR ISOLATED DAMAGING WIND AND POSSIBLY AN ISOLATED TORNADO.
