   NWS STORM PREDICTION CENTER NORMAN OK
   0746 PM CDT SAT JUN 13 2009
   
   AREAS AFFECTED...WESTERN/NORTH TX INTO WESTERN/SOUTHERN OK AND
   SOUTHEAST CO/SOUTHWEST KS
   
   CONCERNING...TORNADO WATCH 398...399...
   
   VALID 140046Z - 140145Z
   
   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 398...399...CONTINUES.
   
   TORNADO WATCHES 398/399 CONTINUE UNTIL 04Z/06Z RESPECTIVELY...WITH A
   BROAD CORRIDOR OF SUPERCELL/SEVERE STORM POTENTIAL LIKELY TO
   CONTINUE FROM SOUTHEAST CO/SOUTHWEST KS INTO WESTERN/NORTHERN TX AND
   WESTERN OK THIS EVENING.
   
   HIGHLY COMPLEX/WIDESPREAD SEVERE SCENARIO CONTINUES TO UNFOLD ACROSS
   MUCH OF NORTHWEST/WEST CENTRAL TX EARLY THIS EVENING. WITHIN WW
   398...THE MOST PROLIFIC STORM ACROSS THE WESTERN PART OF NORTH TX
   /HASKELL AND THROCKMORTON COUNTIES AS OF 0030Z/ WILL LIKELY CONTINUE
   TO DEVELOP EAST-SOUTHEASTWARD OVER THE NEXT FEW HOURS AMIDST A
   SOUTHEASTERLY MOIST/HIGHLY UNSTABLE INFLUX. THE 00Z FORT WORTH
   OBSERVED RAOB REFLECTS VERY STEEP MID LEVEL LAPSE RATES IN EXCESS OF
   8 C/KM AND A MEAN MIXING RATIO OF 17 G/KG...WHICH IS RESULTING IN
   STRONG MLCAPE IN EXCESS OF 4200 J/KG. THE AFOREMENTIONED STORM WILL
   LIKELY CONTINUE TO EXHIBIT SUPERCELLULAR CHARACTERISTICS WITH
   ASSOCIATED TRANSIENT/RAIN EMBEDDED TORNADO POTENTIAL OVER THE NEXT
   1-2 HOURS...BUT OTHERWISE...A DEVELOPING COLD POOL/CONTINUED STORM
   MERGERS ARE SUGGESTIVE OF A TREND TOWARD SEVERE MCS DEVELOPMENT
   ACROSS NORTH TX INTO ADJACENT PORTIONS OF WESTERN/SOUTHERN OK.
   
   FARTHER NORTH IN TORNADO WATCH 399 ACROSS THE TX PANHANDLE AND
   SOUTHEAST CO/SOUTHWEST KS...OTHER SUPERCELLS WITH TORNADO/LARGE HAIL
   POTENTIAL WILL LIKELY CONTINUE TO DEVELOP NORTHEASTWARD/EXPAND
   ACROSS THE TX/OK PANHANDLES THROUGH THE EVENING...EVENTUALLY AIDED
   BY THE INCREASE OF A SOUTHERLY LOW LEVEL JET ACROSS THE SOUTHERN
   HIGH PLAINS. WITH 40 KT MID LEVEL ATOP MOIST/SOUTHEASTERLY FLOW IN
   THE BOUNDARY LAYER...OTHER SUPERCELLS ACROSS SOUTHEAST CO WILL
   LIKELY CONTINUE TO MOVE EASTWARD INTO/ACROSS PORTIONS OF
   SOUTHWEST/PERHAPS WEST CENTRAL KS OVER THE NEXT SEVERAL HOURS...WITH
   CONTINUED LARGE HAIL/ISOLATED TORNADIC POTENTIAL.
   
   AREAS ADJACENT TO TORNADO WATCHES 398/399...INCLUDING PORTIONS OF
   WEST CENTRAL/NORTH CENTRAL TX INTO WESTERN/CENTRAL OK AND
   SOUTHWEST/WEST CENTRAL KS...ARE BEING MONITORED FOR ONE OR MORE
   ADDITIONAL WATCHES OR LOCAL EXTENSIONS.
