...HEAVY RAINFALL AND FLOODING A CONCERN MONDAY AFTERNOON THROUGH
MONDAY NIGHT...

A VERY MOIST AIRMASS WILL BE IN PLACE ACROSS NORTHEAST ILLINOIS
AND NORTHWEST INDIANA ON MONDAY. A COLD FRONT WILL APPROACH MONDAY
AFTERNOON LEADING TO A ROUND OF POTENTIALLY STRONG TO SEVERE
THUNDERSTORMS. THESE STORMS WILL BE EFFICIENT RAIN
PRODUCERS...WITH 2 INCH PER HOUR RATES POSSIBLE. INDICATIONS ARE
THAT THE FRONT MAY BE SLOW MOVING MONDAY EVENING WHICH WOULD ALLOW
THUNDERSTORMS TO PERSIST OVER THESE AREAS FOR A PERIOD OF OF 3 TO
6 HOURS.

AT THIS TIME THE PRIMARILY FOCUS IS GENERALLY SOUTH OF INTERSTATE
80 AND EAST OF INTERSTATE 55. MANY STREAMS IN THIS AREA CONTINUE
TO EXPERIENCE INCREASED FLOWS AS ANYWHERE FROM 2 TO 6 INCHES OF
RAIN FELL ON SATURDAY EVENING. WITH THE POTENTIAL FOR HEAVY
RAINFALL AGAIN MONDAY AFTERNOON AND EVENING...THIS COULD LEAD TO
INCREASED CONCERNS OF FLOODING OF LOW LYING AREAS AND PUSHING
AREA STREAMS INTO FLOOD STAGE. STAY TUNED FOR THE LATEST FORECASTS
FOR UPDATES ON THE FLOOD POTENTIAL MONDAY AFTERNOON AND EVENING.
