   AREAS AFFECTED...NRN OH/NRN IND/FAR SRN LOWER MI
   
   CONCERNING...SEVERE THUNDERSTORM WATCH 826...
   
   VALID 012334Z - 020100Z
   
   A LARGE CLUSTER OF STRONG CONVECTION MOVING ACROSS THE CNTRL AND ERN
   PORTION OF WW826 WILL HAVE THE POTENTIAL FOR WIND DAMAGE AND/OR
   LARGE HAIL.
   
   ANALYSIS SHOWS A COLD FRONT ACROSS LAKE MICHIGAN EXTENDING WSWWD
   ACROSS NRN IL. CONVECTION IN A WARM ADVECTION REGION AHEAD OF THE
   BOUNDARY IS BEING SUSTAINED BY STRONG LOW-LEVEL CONVERGENCE OVER NRN
   OH. SFC PRESSURE RISES HAVE INCREASED IN SRN LOWER MI SUGGESTING A
   COLD POOL MAY BE DEVELOPING. IF THIS HAPPENS...THE WIND DAMAGE
   THREAT WILL INCREASE ACROSS NRN OH. FARTHER W ACROSS NWRN IND...A
   SHORT BOWING LINE IS MOVING INTO THE WRN PORTION OF WW826. WIND
   DAMAGE WILL BE LIKELY AS THIS CLUSTER MOVES ACROSS NRN IND OVER THE
   NEXT FEW HOURS. A PLUME OF STEEP LAPSE RATES EXTENDING EWD ACROSS
   CNTRL IL INTO WRN IND WILL ALSO RESULT IN A POTENTIAL FOR LARGE
   HAIL.
