DISCUSSION
HIGH TEMPERATURES TODAY WILL BE IN THE MID TO UPPER 80S ACROSS MOST
OF THE AREA WITH ONSHORE FLOW HOLDING TEMPERATURES IN THE UPPER
70S TO AROUND 80 NEAR THE LAKESHORE. THE LOWEST RELATIVE HUMIDITY
VALUES ARE EXPECTED IN THE CHICAGO METRO AGAIN TODAY AWAY FROM
THE LAKESHORE WHERE THEY MAY DIP INTO THE UPPER 30 TO MID 40
PERCENT RANGE IN THE AFTERNOON. WINDS WILL BE GENERALLY LIGHT OUT
OF THE SOUTH THROUGH THE DAY UP TO AROUND 5 TO 10 MPH. A LATE
MORNING/EARLY AFTERNOON LAKE BREEZE WILL TURN WINDS EASTERLY IN
LAKE ADJACENT COUNTIES IN ILLINOIS AND TO THE NORTHEAST ALONG THE
IMMEDIATE INDIANA SHORE.
A GRADUAL INCREASE IN HEAT AND HUMIDITY WILL CONTINUE THROUGH THE
END OF THE WEEK WITH PEAK AFTERNOON HEAT INDICES IN THE 95 TO 100
DEGREE RANGE FRIDAY AND SATURDAY. WHILE A FEW SHOWERS CAN'T BE
RULED OUT LATE TONIGHT WELL SOUTHWEST OF THE CHICAGO METRO AND
NORTH OF I-80 THURSDAY NIGHT, OUR NEXT BEST CHANCE OF SHOWERS AND
THUNDERSTORMS RETURNS EARLY NEXT WEEK.
