AREAS AFFECTED...CENTRAL IL / INDIANA

CONCERNING...SEVERE THUNDERSTORM POTENTIAL 

VALID 190253Z - 190400Z

STORMS WILL CONTINUE TO FORM OVER IL AND MOVE EWD INTO INDIANA. A WW
MIGHT BE REQUIRED FOR DAMAGING WIND POTENTIAL.

LOW LEVEL WARM ADVECTION IN VICINITY OF WEAK FRONTAL BOUNDARY WILL
CONTINUE TO FORCE NEW STORM DEVELOPMENT THROUGH THE EARLY MORNING
HOURS. 00Z ILX SOUNDING INDICATES STRONG INSTABILITY IN PLACE...AND
AREA VWPS AND PROFILERS SHOW STRONG VEERING IN THE LOW LEVELS AND
ENOUGH INCREASING SPEED SHEAR WITH HEIGHT FOR SOME SUPERCELLS. GIVEN
LARGE MOISTURE CONTENT AND POOR LAPSE RATES AND WARM TEMPERATURES
ALOFT...DAMAGING WINDS WILL BE THE MAIN THREAT...ALTHOUGH SOME HAIL
MAY OCCUR WITH THE STRONGEST CELLS.
