MESOSCALE DISCUSSION 2363
   NWS STORM PREDICTION CENTER NORMAN OK
   0347 PM CST MON NOV 10 2008
   
   AREAS AFFECTED...PARTS OF CENTRAL/NW TX AND SW OK
   
   ENVIRONMENT AND SEVERE PARAMETERS REMAIN FAVORABLE FOR ORGANIZED
   STORMS AND ATTENDANT TORNADO THREAT ACROSS TORNADO WATCH 929.  
   
   MID-AFTERNOON SURFACE ANALYSIS MAINTAINED A WARM FRONT EXTENDING
   FROM SWRN LA NWWD TO S OF THE DALLAS-FORT WORTH METROPLEX AND THEN
   THROUGH NW TX TO ERN TX PANHANDLE.  A DRY LINE HAD MADE THE GREATEST
   EWD PROGRESS INTO NW TX WHERE IT MERGED WITH THE AFOREMENTIONED WARM
   FRONT...AND THEN TRAILED SSWWD THROUGH THE WRN EXTENT OF WW 929 TO
   VAL VERDE COUNTY.  REGIONAL RADARS INDICATED ROTATING STORMS OVER
   EAST CENTRAL PART OF TORNADO WATCH AS THIS ACTIVITY MOVED NEWD IN
   VICINITY OF WARM FRONT WHERE LOW LEVEL DIRECTIONAL SHEAR IS THE
   GREATEST.  ADDITIONAL STORMS WILL DEVELOP ACROSS SRN HALF OF THE
   WATCH ALONG AND AHEAD OF ADVANCING DRY LINE AND WITHIN LOW LEVEL
   CONVERGENCE ZONE THAT EXTENDED NNWWD INTO SERN PART OF THE WATCH. 
   CLOUDS/PRECIPITATION LOCATED E/NE OF WARM FRONT WILL MAINTAIN A MORE
   STABLE AIR MASS AND SHOULD INHIBIT SEVERE THREAT SPREADING E OF WW
   929.
   
   POTENTIAL FOR SURFACE BASED STORMS ACROSS NRN MOST PART OF
   WW...GENERALLY N OF A LINE FROM JONES TO JACK COUNTIES...WILL
   CONTINUE TO DIMINISH AS DRY LINE MOVES EWD AND EFFECTIVELY REDUCES
   SIZE OF NRN EXTENT OF WARM SECTOR.
