CENTRAL AND NORTHEAST ILLINOIS...AND NORTHWEST INDIANA.

.DAY ONE...TODAY AND TONIGHT

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS THIS AFTERNOON AND 
EVENING OVER THE ENTIRE AREA.

SHOULD END AROUND 6 PM FOR AREAS WEST OF INTERSTATE 39 IN ILLINOIS...

AT NOON...A VERY MOIST AND UNSTABLE ATMOSPHERE IS OVER THE 
REGION...WITH A SURFACE LOW PRESSURE AREA IN CENTRAL IOWA...AND 
TRAILING COLD FRONT. THE LOW AND FRONT WILL MOVE ACROSS THE AREA 
LATER THIS AFTERNOON AND EVENING.  THE LIKELY SCENARIO IS FOR 
THUNDERSTORMS TO DEVELOP IN EASTERN MISSOURI AND WEST CENTRAL 
ILLINOIS...WITH THE STORMS MOVING NORTHEAST INTO OUR AREA.  THAT

THE EXTENSIVE CLOUD COVER MOVING FROM WEST TO EAST ACROSS THE REGION
