MCS OVER IL IS CONT IS STRENGTH AS IT MOVES EAST. RUC LI OVER IL
RUNNING -2 WHILE GOES TO PLUS 6 OVER CENTRAL CENTRAL INDIANA. AIR
ALSO DRIES OUT WITH DEW POINTS DROPPING BY 10 DEGREES FROM IL TO

LIMITS. WILL GO WITH A CHANCE TO SCATTERED THUNDERSTORMS OVER ALL

HIGH TEMPERATURES YESTERDAY IN ILL REACHED THE LOWER TO MID 80S. THE
