WE ARE MONITORING AREA OVER E CENTRAL AND SERN MO FOR ADDITIONAL WW.


BROKEN LINE OF STRONG STORMS CONTINUE TO MOVE SSEWD ACROSS E CENTRAL
MO AND CENTRAL IL.  NEW DEVELOPMENT ACROSS PARTS OF E CENTRAL MO IS
DEVELOPING ALONG WEAK COLD FRONT/MID LEVEL TROUGH AXIS AND WILL BE
MOVING INTO MODERATELY UNSTABLE AIR MASS THAT EXTENDS EWD JUST TO
THE SOUTH OF THE CONVECTIVE LINE/BOUNDARY.  MLCAPE IS 1500-2000 J/KG
AND RUC SOUNDINGS COMBINED WITH LATEST RAOB DATA SHOWS STEEP LOW
LEVEL LAPSE RATES OF 7.0 TO 7.5C/KM. FOR EXAMPLE...THE RUC SOUNDING
FOR KFAM INDICATES WEAK CAPPING INVERSION WITH AN MLCAPE OF 2500
J/KG WITH BRN SHEAR OF 53 M2/S2. THIS COMBINED WITH STRONG UPPER
LEVEL DIVERGENCE IS ENHANCING LIFT AHEAD OF THE ADVANCING BOUNDARY. 
THESE STORMS HAVE THE POTENTIAL FOR HAIL AND STRONG GUSTY WINDS
WITHIN THE WW AREA AND NEAR AND S OF THE STL AREA NEXT FEW HOURS.
