   ...SYNOPSIS...
   STRONG UPPER TROUGH AND ASSOCIATED VORT MAX NOW OVER THE FOUR
   CORNERS REGION WILL CONTINUE MOVING EWD TOWARD THE CENTRAL AND SRN
   PLAINS THROUGH THE END OF THE PERIOD.  IN RESPONSE...SURFACE LOW NOW
   OVER NERN NM / SERN CO WILL MOVE EWD ACROSS OK.  STRONG WARM
   ADVECTION AHEAD OF THIS LOW WILL LIKELY CONTRIBUTE TO THUNDERSTORM
   DEVELOPMENT LATER IN THE PERIOD.
   
   ...PARTS OF THE CENTRAL AND SRN PLAINS EWD TO THE MID MS VALLEY...
   SHOWERS AND PERHAPS A FEW LIGHTNING STRIKES CAN BE EXPECTED ACROSS
   PORTIONS OF THE CENTRAL AND SRN HIGH PLAINS AHEAD OF APPROACHING
   MID-LEVEL FEATURE OVER THE NEXT SEVERAL HOURS. 
   
   MORE WIDESPREAD THUNDERSTORMS WILL BE POSSIBLE LATER IN THE PERIOD
   ACROSS SERN KS / ERN OK EWD ACROSS THE OZARKS. ALTHOUGH EVENING
   RAOBS ACROSS THIS REGION INDICATE THAT SUBSTANTIAL MOISTENING WILL
   BE REQUIRED IN THE 850 TO 700 MB LAYER TO SUPPORT CONVECTIVE
   DEVELOPMENT...THETA-E ADVECTION ASSOCIATED WITH INTENSIFYING SSWLY
   LOW-LEVEL JET SHOULD PROVIDE SUFFICIENT MOISTENING TO YIELD MINIMAL
   INSTABILITY.  ALTHOUGH THUNDERSTORM DEVELOPMENT WILL BE POSSIBLE AS
   A RESULT...IT APPEARS THAT DEGREE OF DESTABILIZATION WILL LIKELY BE
   INSUFFICIENT TO SUPPORT A SEVERE HAIL THREAT.
