THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH CENTRAL ILLINOIS...
NORTHEAST ILLINOIS AND NORTHWEST INDIANA.

 A WARM FRONT HAS LIFTED NORTH OF THE AREA TODAY INTO SOUTHERN
WISCONSIN. MOST OF THE THUNDERSTORM ACTIVITY IS EXPECTED TO
REMAIN ALONG AND NORTH OF THE FRONT...HOWEVER THERE IS A CHANCE
THAT A FEW THUNDERSTORMS MAY DEVELOP FARTHER SOUTH...ESPECIALLY
OVER FAR NORTHERN ILLINOIS. AS THE FRONTAL BOUNDARY SAGS SOUTH
OVERNIGHT...THE ENVIRONMENT WILL BE PRIMED TO SUPPORT SEVERE
WEATHER...PRIMARILY STRONG WINDS AND LARGE HAIL. SINCE THE FRONT
WILL BE SLOW-MOVING AND THERE WILL BE LARGE AMOUNTS OF DEEP LAYER
MOISTURE AND LOCALLY HEAVY RAINFALL WILL ALSO BE POSSIBLE.

MINOR FLOODING WILL CONTINUE ALONG PORTIONS OF THE KANKAKEE RIVER
IN NORTHWEST INDIANA.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
