   MARGINALLY SEVERE HAIL WILL BE POSSIBLE WITH MORE INTENSE STORMS
   DEVELOPING ACROSS DISCUSSION AREA.  A WW IS NOT ANTICIPATED ATTM.
   
   A CLUSTER OF TSTMS HAVE RECENTLY DEVELOPED OVER FAR NERN MO /SE IRK/
   WITHIN ZONE OF STRONG LOW-LEVEL WAA OCCURRING N OF SURFACE WARM
   FRONT WHICH EXTENDED FROM JUST N OF SZL TO NEAR OR JUST N OF STL AS
   OF 04Z.  RUC FORECAST SOUNDINGS SUGGEST THAT THESE STORMS ARE LIKELY
   ROOTED IN AN ELEVATED MOIST LAYER ROUGHLY AROUND 900-850 MB WHICH IS
   CONTRIBUTING TO MUCAPES OF 600-800 J/KG.  
   
   EXPECT THIS ACTIVITY TO INCREASE IN COVERAGE AS IT MOVES NEWD INTO
   PORTIONS OF FAR SERN IA AND W-CNTRL MO OVERNIGHT.  SOME MARGINALLY
   SEVERE HAIL MAY ACCOMPANY THE MORE INTENSE STORMS...HOWEVER IT
   APPEARS THE WEAK INSTABILITY WILL PRECLUDE A MORE SUBSTANTIAL SEVERE
   THREAT.
