AREAS AFFECTED...EXTREME SERN IL...CNTRL/ERN KY...CNTRL/SRN
IND...SWRN/SCNTRL OH

CONCERNING...SEVERE THUNDERSTORM WATCH 188...192...

VALID 222211Z - 222345Z

21Z MESOANALYSIS PLACES A 998MB MESOLOW VCNTY KIND WITH A WARM FRONT
EXTENDING EWD ACROSS THE KDAY AREA THEN SEWD TO THE MID-OH VLY. 
ANOTHER COLD FRONT EXTENDS SWD FROM THE LOW INTO THE LAND-BETWEEN-
THE-LAKES.  THE MAIN COLD FRONT EXTENDED FROM KCAK TO NEAR KIND THEN
WWD INTO CNTRL IL.  

A LINE OF TSTMS HAS EVOLVED ALONG THE N-S COLD FRONT AND CONTINUES
TO MOVE ENEWD INTO SCNTRL IND AND NWRN KY.  THE LINE CONSISTS OF A
MIX OF SUPERCELLS AND BOW ECHOES.  VWP FROM KEVV CLEARLY SHOWED A
REAR INFLOW JET WITH AN...OTHERWISE...UNIDIRECTIONAL SWLY FLOW
REGIME THROUGH THE COLUMN.  THUS...MAINLY DAMAGING WINDS CAN BE
EXPECTED AS THIS LINES MOVE EWD THROUGH SRN IND AND INTO CNTRL KY.

MEANWHILE...MORE ISOLD SUPERCELLULAR STRUCTURES HAVE DEVELOPED AHEAD
OF THE LINE ACROSS CNTRL/SERN IND AND CNTRL KY.  THESE STORMS WERE
DEVELOPING WITHIN THE NOSE OF A THETA-E RIDGE AND WILL PROBABLY
CONTINUE TO GROW AS THEY MOVE ENEWD TOWARD SWRN/WCNTRL OH AND NCNTRL
KY.  FLOW PROFILES SUGGEST THAT MAINLY LARGE HAIL AND DAMAGING WINDS
WILL THE PRIMARY SEVERE THREATS.  HOWEVER...STORMS THAT APPROACH THE
WARM FRONT ACROSS CNTRL IND INTO WCNTRL/SWRN OH MAY TEND TO EXHIBIT
LOW-LEVEL ROTATION AND ISOLD TORNADOES MAY OCCUR.
