SPC MESOSCALE DISCUSSION 0713 FOR SE KS/SW MO
   CONCERNING...SEVERE THUNDERSTORM POTENTIAL...
   
   VALID 080328Z - 080600Z
   
   CONVECTIVE TRENDS ARE BEING MONITORED FOR POSSIBILITY OF NEW WW
   EAST OF 251.  AT CURRENT FORWARD PROPAGATION...BOWING CONVECTIVE
   LINE WILL CLEAR EAST EDGE OF WATCH BY 06-07Z TIME FRAME.
   
   BOW ECHO HAS INTENSIFIED SIGNIFICANTLY DURING THE PAST...AND IS
   ACCELERATING EASTWARD AT 35 TO 40 KT THROUGH THE JOPLIN MO AREA...
   ON COOL SIDE OF CONVECTIVELY ENHANCED BOUNDARY EXTENDING FROM
   HARRISON AR THROUGH THE TULSA/ENID AREAS OF OKLAHOMA.  VAD WIND
   DATA INDICATE VERY STRONG SHEAR NORTH OF BOUNDARY...WITH 15 TO 25
   KT EASTERLY LOW-LEVEL FLOW VEERING TO 35 KT WESTERLY AT MID-LEVELS. 
   THIS WILL HELP MAINTAIN CONVECTIVE SYSTEM EASTWARD THROUGH THE
   SPRINGFIELD AREA WITHIN THE NEXT 1 TO 2 HOURS.  POTENTIAL FOR
   DAMAGING WIND GUSTS IS IN QUESTION EASTWARD INTO SOUTH CENTRAL
   /SOUTHEAST MISSOURI...FARTHER NORTH/EAST OF OUTFLOW BOUNDARY...
   WHERE SURFACE AIR MASS IS COOL/STABILIZED FROM PRIOR CONVECTIVE
   ACTIVITY...AND LOW-LEVEL CONVERGENCE/STORM-RELATIVE INFLOW WILL BE
   WEAKER.
