...MORE SHOWERS AND THUNDERSTORMS...

A COLD FRONT WILL SLOWLY DROP SOUTHEAST ACROSS THE AREA TODAY AND
TONIGHT.  THIS COLD FRONT WILL INTERACT WITH VERY UNSTABLE AIR TO THE
SOUTH OF IT TO PRODUCE PERIODS OF SHOWERS AND THUNDERSTORMS TODAY AND
TONIGHT.  DUE TO THE UNSTABLE AIR...AND GOOD UPPER LEVEL SUPPORT...
THERE IS THE POTENTIAL FOR SEVERE THUNDERSTORMS DURING THE AFTERNOON
AND EVENING HOURS.  THE GREATEST THREAT IS FOR STRONG GUSTY WINDS AND
LARGE HAIL.

THIS MORNING AN INITIAL BATCH OF SHOWERS AND THUNDERSTORMS WILL MOVE
THROUGH THE AREA.  SOME THUNDERSTORMS MAY BE SEVERE...BUT THE GREATEST
THREAT THIS MORNING IS FOR STRONG GUSTY WINDS.  THE GREATEST LIKELIHOOD
OF DAMAGING WINDS IS NORTH OF INTERSTATE 80.  THIS ACTIVITY SHOULD MOVE
EAST OF THE AREA BY MID DAY.

DURING THE AFTERNOON SUNSHINE WILL HEAT THE LOWER ATMOSPHERE...
INCREASING THE INSTABILITY FOR THE AFTERNOON AND EVENING HOURS.  BY
AFTERNOON...MORE SHOWERS AND THUNDERSTORMS WILL MOVE BACK OVER THE
AREA.  THESE AFTERNOON AND EVENING THUNDERSTORMS WILL HAVE A GREATER
THREAT OF PRODUCING DAMAGING WINDS AND HAIL.  SOME SHOWERS AND
THUNDERSTORMS WILL LINGER OVERNIGHT TONIGHT.

THERE IS ALSO IS THE POTENTIAL FOR SIGNIFICANT RAINFALL TO BE GENERATED
FROM THESE THUNDERSTORMS.  DUE TO LAST TUESDAYS HEAVY RAIN EVENT...SOME
RIVERS REMAIN IN FLOOD...AND AREA GROUND MOISTURE IS STILL VERY HIGH.
SO...AREA RIVERS...CREEKS AND STREAMS WILL HAVE TO BE WATCHED
CAREFULLY FOR POSSIBLE FLOOD PROBLEMS.  OF SPECIAL CONCERN ARE PORTIONS
OF WESTERN AND NORTHWESTERN ILLINOIS.

SPOTTER ACTIVATION MAY BE NECESSARY TODAY AND TONIGHT.

EMERGENCY MANAGERS AND EMERGENCY RESPONDERS WHO HAVE RESPONSIBILITIES
ALONG AREA RIVERS THAT ARE IN FLOOD...OR HAVE RECENTLY BEEN IN
