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

.DAY ONE...TODAY AND TONIGHT.

  WEATHER HAZARDS EXPECTED:

  SCATTERED THUNDERSTORMS...THE STRONGEST OF WHICH MAY PRODUCE:
   WINDS GUSTING IN EXCESS OF 60 MPH.
   FREQUENT CLOUD TO GROUND LIGHTNING.
   LOCALLY HEAVY RAINFALL.

  AREAS AFFECTED AND TIMING:

   ISOLATED STRONG THUNDERSTORMS WILL DEVELOP LATE THIS MORNING

   NORTHERN ILLINOIS INTO NORTHWEST INDIANA THIS AFTERNOON

  DISCUSSION:

   VERY WARM AND MOIST AIR WILL CONTINUE TO LIFT NORTH ACROSS
   NORTHERN ILLINOIS AND NORTHWEST INDIANA TODAY. AN AREA OF
   LOW PRESSURE LIFTS NORTH FROM NORTHERN MISSOURI INTO FAR
   EASTERN IOWA EARLY THIS AFTERNOON. THIS LOW WILL LIFT A
   BOUNDARY NORTH ACROSS THE OUTLOOK AREA...ALLOWING WINDS TO
   BACK TO THE SOUTHEAST ALONG AND JUST NORTH OF THE BOUNDARY.
   THE ATMOSPHERE SHOULD BECOME UNSTABLE BY LATE THIS MORNING
   WITH A FEW DISCRETE STRONG THUNDERSTORMS DEVELOPING SHORTLY
   AFTER NOON. AS THE WIND FIELDS STRENGTHEN...THE INTENSITY
   OF THUNDERSTORMS MAY INCREASE ACROSS FAR NORTHEAST ILLINOIS
   AND NORTHWEST INDIANA. WHILE DAMAGING WIND GUSTS IN EXCESS
   OF 60 MPH APPEARS TO BE THE MAIN HAZARD...THUNDERSTORMS ALONG
   OR JUST NORTH OF THE BOUNDARY COULD PRODUCE A SMALL BUT NON-ZERO
   CHANCE FOR AN ISOLATED TORNADO EARLY THIS AFTERNOON.

THERE WILL BE PERIODIC CHANCES OF THUNDERSTORMS WEDNESDAY...THEN
