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

.DAY ONE... TODAY AND TONIGHT

THERE IS A MODERATE RISK OF SEVERE THUNDERSTORMS SOUTH OF A LINE 
FROM DIXON TO TINLEY PARK TO RENSSELAER...AND THERE IS A SLIGHT RISK 
NORTH OF THAT AREA. THE SEVERE STORMS ARE MOSTLY LIKELY TO OCCUR 
FROM ABOUT 400 PM THROUGH 1000 PM. THE MAIN SEVERE WEATHER THREAT IS 
DAMAGING WINDS AND LARGE HAIL ASSOCIATED WITH A SQUALL LINE.

SHOWERS AND THUNDERSTORMS ASSOCIATED WITH A WARM FRONT WILL MOVE 
THROUGH NORTHERN ILLINOIS AND NORTHERN INDIANA THIS MORNING INTO 
EARLY AFTERNOON. THE BULK OF THE RAIN IS FORECAST TO MOVE NORTH AND 
EAST OF ILLINOIS AND INDIANA EARLY THIS AFTERNOON. 

IF THERE IS ENOUGH BREAK UP OF THE CLOUD COVER THIS AFTERNOON... 
HEATING FROM THE SUN AND SURGING DEWPOINTS ON STRONG SOUTH WINDS 
WILL SUFFICIENTLY DESTABILIZE THE ATMOSPHERE FOR STRONG 
THUNDERSTORMS TO DEVELOP. LOW LEVEL WINDS...A STRONG UPPER LEVEL LOW 
PRESSURE SYSTEM...AND A STRONG JET STREAM ALOFT WILL FAVOR 
ORGANIZED THUNDERSTORMS. A SQUALL LINE IS EXPECTED TO DEVELOP AHEAD 
OF A COLD FRONT AND MOVE WEST TO EAST ACROSS NORTHERN ILLINOIS AND 
NORTHWEST INDIANA LATE THIS AFTERNOON AND THIS EVENING. 

LOCALLY HEAVY DOWNPOURS ARE ALSO POSSIBLE WITH THE STORMS...
ESPECIALLY SOUTH OF INTERSTATE 80...BUT STORMS SHOULD BE MOVING FAST 
ENOUGH THAT FLASH FLOODING IS NOT A MAJOR THREAT. RAINFALL OVER FAR 
NORTHERN ILLINOIS...WHERE MINOR RIVER FLOODING IS OCCURRING...IS NOT 
EXPECTED TO BE EXCESSIVE...BUT COULD BE SUFFICIENT TO AGGRAVATE OR 
PROLONG ONGOING STREAM FLOODING.

EVENING AND AGAIN TUESDAY AFTERNOON AND EARLY EVENING BUT THE STORMS
