   CORRECTED FOR TYPO IN STATES LISTING
   
   BAND OF TSTMS THAT HAS DEVELOPED OVER ERN KS...GENERALLY BETWEEN
   CNK-CNU...IS EXPECTED TO MOVE/EXPAND SEWD ACROSS PORTIONS NERN
   OK...AND PERHAPS ADJOINING SLIVERS OF SWRN MO AND NWRN AR...THROUGH
   10Z.  ADDITIONAL CONVECTIVE DEVELOPMENT IS OCCURRING OVER NWRN KS
   BETWEEN GLD-MCK...AND MAY FILL IN EWD TOWARD CNK AREA AND NWRN
   PORTION OF OTHER TSTM BAND.  STRONGEST CORES MAY PRODUCE SVR HAIL
   FOR BRIEF PERIODS.  HOWEVER THREAT DOES NOT APPEAR SUFFICIENTLY
   INTENSE OR WELL-ORGANIZED TO WARRANT WW ATTM. IN ADDITION...BRIEF
   BURSTS OF RAIN RATES 2-2.5 INCHES/HOUR ARE POSSIBLE ESPECIALLY FROM
   CONVECTION OVER ERN KS...WHICH MAY CONTINUE TO TRAIN NEAR ITS MEAN
   AXIS.
   
   STG/ELEVATED LOW LEVEL WAA IS OCCURRING NE OF SFC WARM FRONT THAT
   EXTENDS FROM SERN CO SEWD ACROSS N-CENTRAL OK.  BROAD 30-40 KT LLJ
   -- INITIALLY EVIDENT IN VWP AND PROFILER WINDS -- IS EXPECTED TO BE
   MAINTAINED IN INTENSITY THROUGH 10Z...BUT VEERING WITH TIME. 
   ASSOCIATED LOW LEVEL MOISTURE TRANSPORT AND ASCENT TO LFC WILL
   CONTINUE TO REALIZE ELEVATED MUCAPE UP TO 1500 J/KG...ROOTED ATOP
   WARM FRONTAL ZONE WITHIN 700-800 MB LAYER.  SERIES OF FCST SOUNDINGS
   ACROSS THIS CORRIDOR SUGGESTS EFFECTIVE SHEAR GENERALLY WILL BE AOB
   30 KT...BUT WITH POCKETS OF 30-40 KT MAGNITUDES WHERE BUOYANT LAYER
   CAN EXTEND MORE DEEPLY INTO STG UPPER LEVEL FLOW.  GIVEN THESE
   CONDITIONS...EXPECT GENERAL MULTICELLULAR CHARACTER...WHICH SHOULD
   LIMIT POTENTIAL FOR VERY LARGE OR DAMAGING HAIL...AND KEEP MOST
   EVENTS MRGL IN NATURE.  SLGT NWD/NEWD MOTION OF ELEVATED WARM FRONT
   MAY LIKEWISE GRADUALLY SHIFT CORRIDOR OF STRONGEST LOW LEVEL LIFT.
