TODAY WILL BE ANOTHER WARM DAY WITH TEMPERATURES RISING IN TO THE UPPER
80S TO AROUND 90.  HUMIDITY LEVELS WILL ALSO BE HIGHER THAN THOSE OF
THE LAST SEVERAL DAYS.  THE WARM TEMPERATURES AND HIGH HUMIDITY WILL
CREATE HEAT INDICES IN THE MIDDLE 90S THIS AFTERNOON.

ISOLATED AFTERNOON AND EVENING THUNDERSTORMS WILL POSSIBLE OVER PARTS OF
WEST CENTRAL ILLINOIS...SOUTHEAST IOWA AND NORTHEAST MISSOURI.  THE
THUNDERSTORMS ARE EXPECTED TO DEVELOP ON THE NORTHERN EDGE OF AN UPPER
LEVEL LOW PRESSURE SYSTEM OVER THE LOWER MISSISSIPPI VALLEY.
STEERING WINDS IN THE UPPER ATMOSPHERE WILL BE WEAK AND MOISTURE LEVELS
WILL BE HIGH.  THEREFORE...ANY THUNDERSTORMS THAT DEVELOP WILL MOVE VERY
LITTLE...AND WILL HAVE THE POTENTIAL TO PRODUCE SIGNIFANCT RAINFALL
AMOUNTS.

A COLD FRONT MOVING OUT OF SOUTHERN MINNESOTA AND EASTERN NEBRASKA WILL
BE THE FOCUS FOR SCATTERED THUNDERSTORM DEVELOPMENT THIS EVENING...OVER
PARTS OF EAST CENTRAL IOWA AND NORTHWEST ILLINOIS. A FEW OF THE STORMS
COULD REACH SEVERE LIMITS LATE THIS EVENING ALONG AND NORTH OF HIGHWAY
30.  THE GREATEST SEVERE WEATHER THREAT WILL BE THREE QUARTER INCH
HAIL.  ISOLATED HEAVY RAINFALL WILL ALSO BE POSSIBLE.  THE
THUNDERSTORMS SHOULD DIMINISH IN INTENSITY BY MIDNIGHT.

AS THE COLD FRONT CONTINUES SLOWLY SOUTHEAST WEDNESDAY...
THUNDERSTORMS ARE EXPECTED TO RE-INTENSIFY DURING THE LATE MORNING AND
AFTERNOON HOURS ALONG THE FRONT...OVER SOUTHEAST IOWA...NORTHEAST
MISSOURI AND WEST CENTRAL ILLINOIS.  AGAIN...A FEW OF THESE STORMS COULD
INTENSIFY TO SEVERE LIMITS...AND PRODUCE SOME LARGE HAIL.  ISOLATED
HEAVY RAINFALL IS STILL POSSIBLE.

THURSDAY SHOULD BRING SOME RELIEF FROM THE EARLY SUMMER HEAT AND
HUMIDITY AS DRIER AIR MOVES INTO THE REGION.  HOWEVER...WARMER
TEMPERATURES WILL RETURN FOR THE WEEKEND.

SPOTTER ACTIVATION MAY BE NECESSARY THIS EVENING FOR AREAS NORTH OF
HIGHWAY 30.  SPOTTER ACTIVATION MAY ALSO BE REQUIRED WEDNESDAY
AFTERNOON AND EVENING FOR AREAS SOUTH OF INTERSTATE 80.
