STORM PREDICTION CENTER...NWS/NCEP...NORMAN OK
   DAY 3 CONVECTIVE OUTLOOK...REF AWIPS GRAPHIC PGWK48 KWNS.
    
   VALID 071200-081200
    
   THERE IS A SLIGHT RISK OF SEVERE TSTMS ACROSS THE GULF COAST.
   
   ...SYNOPSIS...
   LARGE SCALE PATTERN WILL BEGIN TO CHANGE BY DAY 3 WITH LARGE HEIGHT
   RISES FORECAST OVER THE ROCKIES...AND THE DOWNSTREAM TROUGH OVER
   THE CENTRAL/ERN CONUS WILL EVOLVE INTO A CONFLUENT/POSITIVE TILT
   CONFIGURATION.  ONE EMBEDDED SHORTWAVE TROUGH...NOW IN THE VICINITY
   OF NV...WILL MOVE NEWD FROM THE MID MS VALLEY BY DAY 3 AND
   DEAMPLIFY.  AN ASSOCIATED SURFACE LOW W OF THE APPALACHIANS SHOULD
   GRADUALLY FILL AS THE MID LEVEL TROUGH WEAKENS...WHILE WEAK
   SECONDARY LOW DEVELOPMENT IS ANTICIPATED NEAR THE MID ATLANTIC
   COAST.  ACROSS THE GULF STATES...A SLOW MOVING COLD FRONT FROM THE
   NW GULF COAST TO THE TN VALLEY SHOULD BEGIN TO ACCELERATE SEWD LATE
   IN THE PERIOD IN RESPONSE TO A DEVELOPING RIDGE OVER THE CENTRAL
   PLAINS.
   
   A FEW SEVERE STORMS WILL BE POSSIBLE ALONG THE SLOW MOVING FRONT
   ACROSS THE GULF STATES...WHERE RICH BOUNDARY LAYER MOISTURE AND
   MODERATE INSTABILITY ARE EXPECTED BENEATH THE SRN FRINGE OF THE
   STRONGER MID LEVEL FLOW.  FARTHER E...THE SEVERE THREAT IS MORE
   UNCERTAIN GIVEN THE POSSIBILITY OF COOL AIR DAMMING E OF THE
   APPALACHIANS...AND A TENDENCY FOR WEAKENING LOW-LEVEL FLOW/SHEAR.
