   ...THERE IS A SLGT RISK OF SVR TSTMS ACROSS PARTS OF OK...FAR NE
   TX...WRN AR AND SRN KS...
   
   ...OK/SRN KS/FAR NE TX/WRN AR...
   CONVECTION IS CURRENTLY DEVELOPING NEAR THE CENTER OF AN UPPER-LOW
   MOVING EWD ACROSS SW KS AND NW OK. A DRY SLOT WRAPPING AROUND THE
   SRN SIDE OF THE LOW IS EVIDENT ON WV IMAGERY ACROSS WRN OK. AS A
   RESULT...SFC TEMPS HAVE WARMED INTO THE MID 70S F ACROSS SW OK WITH
   SBCAPE VALUES APPROACHING 1000 J/KG IN PARTS OF WRN OK. THIS WILL BE
   THE MOST LIKELY LOCATION FOR SFC-BASED DEVELOPMENT THIS AFTERNOON.
   
   SFC ANALYSIS SHOWS A COLD FRONT MOVING SEWD THROUGH THE TX PANHANDLE
   WITH A LOW PRESSURE CENTER IN WRN OK. THE FRONT WILL DRIVE THE SFC
   LOW SEWD INTO SRN OK BY 00Z. LOW-LEVEL CONVERGENCE WILL INCREASE
   EAST AND NORTH OF THE LOW CENTER AND A LINE OF STORMS SHOULD QUICKLY
   DEVELOP LATE THIS AFTERNOON ALONG AND EAST OF A NARROW MOIST AXIS
   EXTENDING NORTH AND SOUTH ALONG THE I-35 CORRIDOR. THE LINE SHOULD
   DEVELOP AND EXPAND SWD AS IT MOVES EWD INTO ERN OK EARLY THIS
   EVENING.
   
   FORECAST SOUNDINGS FOR CNTRL/ERN OK AT 00Z SHOW STRONG 0-6 KM SHEAR
   VALUES WHICH ARE ASSOCIATED WITH A 65 KT MID-LEVEL JET PUNCHING IN
   FROM THE SOUTHWEST. THE SHEAR COMBINED WITH INCREASING INSTABILITY
   SHOULD BE SUFFICIENT FOR ISOLATED SUPERCELLS. MOISTURE ADVECTION AT
   LOW-LEVELS AND COOLING TEMPS AT MID-LEVELS WILL STEEPEN LAPSE RATES
   MAKING CONDITIONS MORE FAVORABLE FOR LARGE HAIL. IN
   ADDITION...STRONG LOW-LEVEL WINDS OF 35 TO 40 KT WILL ENHANCE THE
   WIND DAMAGE POTENTIAL WITH THE FASTER MOVING STORM SEGMENTS.
   ALSO...AN ISOLATED TORNADO THREAT MAY DEVELOP LATE THIS AFTERNOON
   AND EARLY THIS EVENING JUST TO THE WEST OF THE LOW-LEVEL JET ACROSS
   ERN OK AND FAR NE TX WHERE THE BEST INSTABILITY...STRONGEST
   LOW-LEVEL SHEAR AND LOWEST LCL HEIGHTS SHOULD BE LOCATED.
   
   MCS DEVELOPMENT APPEARS LIKELY ACROSS ERN OK THIS EVENING. THE
   SYSTEM SHOULD MOVE EWD INTO AR DURING THE OVERNIGHT HOURS WITH THE
   LARGE HAIL AND WIND DAMAGE THREAT CONTINUING. A MARGINAL SEVERE
   THREAT COULD CONTINUE LATE TONIGHT AS THE SYSTEM MOVES INTO ERN AR
   AND NWRN LA.
