   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.
