August 14, 1988
Eighteen cities in the northeastern U.S. reported record high temperatures for the date, and the water temperature at Lake Erie reached a record 80 degrees. Portland ME reported a record fourteen straight days of 80 degree weather. Milwaukee WI reported a record 34 days of 90 degree heat for the year. Afternoon and evening thunderstorms resulted in about fifty reports of severe weather in the northeastern U.S. One person was killed at Stockbridge MI when a tornado knocked a tree onto their camper. (The National Weather Summary)

August 14, 1987
Slow moving thunderstorms deluged northern and western suburbs of Chicago IL with torrential rains. O'Hare Airport reported 9.35 inches in 18 hours, easily exceeding the previous 24 hour record of 6.24 inches. Flooding over a five day period resulted in 221 million dollars damage. It was Chicago's worst flash flood event, particularly for northern and western sections of the city. Kennedy Expressway became a footpath for thousands of travelers to O'Hare Airport as roads were closed. The heavy rains swelled the Des Plaines River above flood stage, and many persons had to be rescued from stalled vehicles on flooded roads. (13th- 14th)
