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

.DAY ONE...TONIGHT

SOME AREAS OF FOG MAY DEVELOP OUTSIDE METRO CHICAGO AFTER MIDNIGHT 
TONIGHT...REDUCING VISIBILITIES TO A MILE OR TWO IN MANY AREAS. THE 
DENSER FOG WILL LIKELY BE WEST OF INTERSTATE 39. ANY FOG THAT FORMS 
OVERNIGHT WILL BURN OFF AN HOUR OR TWO AFTER SUNUP TUESDAY.

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY

SEVERE THUNDERSTORMS WILL BE POSSIBLE ACROSS THE ENTIRE OUTLOOK AREA 
TUESDAY AFTERNOON AND EVENING. VERY LARGE ATMOSPHERIC INSTABILITY...
COMBINED WITH STRONG UPPER LEVEL WINDS WILL POTENTIALLY ALLOW FOR 
THE DEVELOPMENT OF STRONG TO SEVERE STORMS. AS OF TONIGHT...THE 
EXPECTED EVOLUTION SHOULD BE FOR THE DEVELOPMENT OF ONE OR TWO 
SMALL CLUSTERS OF STORMS IN THE EARLY AFTERNOON...A FEW OF WHICH 
COULD BE SUPERCELLS. LARGE HAIL WILL BE THE MAIN THREAT FROM THESE 
STORMS. THESE CLUSTERS OF STORMS SHOULD THEN ELVOLVE INTO A LARGE 
SQUALL LINE...WHICH WILL LIKELY PRODUCE DAMAGING STRAIGHT LINE WINDS 
IN THE LATE AFTERNOON INTO THE EVENING.

THERE REMAINS SOME QUESTION AS TO HOW THE POTENTIAL DEVELOPMENT OF A 
STORM COMPLEX TONIGHT IN SOUTHERN MINNESOTA WILL IMPACT TOMORROW'S 
STORM ACTIVITY ACROSS THE LOWER WESTERN GREAT LAKES. FOR THAT REASON 
PLEASE CONTINUE TO MONITOR NATIONAL WEATHER SERVICE FORECASTS. 

.SPOTTER INFORMATION STATEMENT...

SPOTTERS ACTIVATION WILL LIKELY BE NEEDED TUESDAY AFTERNOON AND 
EVENING.
