   THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 774
   CONTINUES.
   
   A LINE OF STORMS...PRECEDED BY STRONG OUTFLOW...CONTINUES SWD ACROSS
   THE STATE OF OK. SURFACE ANALYSIS SHOWS VERY STRONG PRESSURE RISES
   OVER NERN OK...WITH SUBSTANTIAL MAGNITUDES ALSO EXTENDING SWWD.
   GIVEN EARLY CONVECTION OVER ERN OK...THESE STORMS HAVE WEAKENED AND
   MAY REMAIN SUB-SEVERE. THE GREATEST THREAT OF SEVERE WIND WILL BE
   OVER SWRN INTO S CNTRL OK WHERE STRONGER INSTABILITY REMAINS...AS
   WELL AS A SLY LOW LEVEL JET. A NEW WW IS NOT EXPECTED AS OUTFLOW MAY
   EVENTUALLY OUTRUN THE STORMS AS WELL AS SOME INCREASING CIN...BUT
   TRENDS WILL CONTINUE TO BE MONITORED.
