SPC MESOSCALE DISCUSSION 1802 FOR CENTRAL AND SOUTHERN OKLAHOMA
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL...
   
   VALID 251539Z - 251900Z
   
   THUNDERSTORMS WILL CONTINUE TO DEVELOP AND MOVE SOUTHEASTWARD
   ACROSS CENTRAL AND SOUTHERN PARTS OF OKLAHOMA OVER THE NEXT FEW
   HOURS.  IF THE ACTIVITY CONTINUES TO INTENSIFY...A WATCH COULD BE
   NEEDED.
   
   LATEST RADAR COMPOSITE LOOPS SHOW THUNDERSTORMS DEVELOPING ACROSS
   PORTIONS OF NORTHERN AND CENTRAL OKLAHOMA.  THIS ACTIVITY HAS BEEN
   SLOWLY INTENSIFYING OVER THE PAST COUPLE OF HOURS.  SURFACE
   OBSERVATIONS SHOW PLENTY OF MOISTURE REMAINS IN PLACE THROUGHOUT
   THE REGION.  THE MORNING SOUNDING FROM NORMAN SHOWED NEARLY 2000
   J/KG OF ELEVATED CAPE.  AS THE ACTIVITY CROSSED WILEY POST AIRPORT
   IN NORTHWESTERN OKLAHOMA CITY...WINDS GUSTED TO 42 KNOTS. 
   ADDITIONALLY...SMALL HAIL WAS OBSERVED IN NORTHERN PARTS OF NORMAN. 
   IT IS POSSIBLE THAT THE ACTIVITY WILL CONTINUE TO INTENSIFY AS IT
   MOVES INTO AREAS THAT HAVE SEEN SOME HEATING THIS MORNING.  THIS
   MAY ALLOW STORMS TO INTENSIFY.  WE WILL CONTINUE TO MONITOR THIS
   AREA FOR A POSSIBLE WEATHER WATCH.
