   THE SEVERE WEATHER THREAT FOR TORNADO WATCH 345 CONTINUES.
   
   LOW LEVEL WARM ADVECTION IS BEGINNING TO INCREASE ACROSS ERN IA/NRN
   MO/NWRN IL AS LLJ STRENGTHENS ACROSS ERN KS INTO THE MID MS VALLEY
   REGION.  THIS INCREASE SHOULD ENHANCE CONVECTIVE THREAT ACROSS MUCH
   OF ERN IA INTO NWRN IL.  ALTHOUGH INSTABILITY AND LAPSE RATES ARE
   SOMEWHAT WEAKER EAST OF THE MS RIVER...SUFFICIENT BUOYANCY EXISTS
   FOR AN EWD EXPANSION OF CONVECTION OVER THE NEXT FEW HOURS.  WILL
   CONTINUE TO MONITOR THIS REGION FOR POSSIBLE WW.
