THIS HAZARDOUS WEATHER OUTLOOK IS FOR NORTH CENTRAL ILLINOIS...
NORTHEAST ILLINOIS AND NORTHWEST INDIANA.
.DAY ONE...TODAY AND TONIGHT.
WEATHER HAZARDS EXPECTED:
SCATTERED THUNDERSTORMS...SOME OF WHICH MAY PRODUCE:
TORRENTIAL RAINFALL.
FREQUENT CLOUD TO GROUND LIGHTNING.
WIND GUSTS OVER 60 MPH.
QUARTER SIZED HAIL.
AREAS AFFECTED AND TIMING:
A LINE OF THUNDERSTORMS IS EXPECTED NORTH OF A WAUKEGAN
TO LA SALLE LINE EARLY THIS EVENING. THE STORMS WILL THEN
SHIFT SOUTH OF INTERSTATE 80 LATE THIS EVENING. THE MAJORITY OF
STORMS LIKELY WILL REMAIN WEST OF THE CHICAGO METRO.
DISCUSSION:
A COLD FRONT WILL SINK SOUTHEAST THROUGH THE REGION THIS
EVENING. INSTABILITY AND WIND SHEAR WILL BE FAVORABLE FOR
SEVERE WEATHER...BUT A STOUT CAP WILL LIMIT STORM FORMATION.
THEREFORE THE FORCING ALONG THE COLD FRONT SHOULD BE THE ONLY
SUFFICIENT SOURCE OF LIFT TO FORCE STORMS. MOISTURE WILL
ALSO BE HIGH SO TORRENTIAL DOWNPOURS ARE EXPECTED. GIVEN THE
RECENT HEAVY RAINFALL...FLASH FLOODING IS POSSIBLE ALONG WITH
RISES ON LOCAL RIVERS AND STREAMS. THE MAIN SEVERE WEATHER
THREATS WILL BE LARGE HAIL AND ISOLATED DAMAGING WIND.
MODERATE TO MAJOR FLOODING CONTINUES ON PORTIONS OF THE KANKAKEE
