During a summer in the early 1950s, I recall Aurora trucks picking up dead fish from the banks of the Fox River. Was hot, dry weather the cause?
–Mel Dormer, Aurora
According to records from the Aurora Sanitary District sewage treatment plants, a combination of low water flow in the Fox River and high temperatures resulted in a serious fish kill in the summer of 1953. The water temperature rose to high as 108 degrees, literally cooking the fish. In Chicago, that summer featured 42 days of 90 degrees or higher temperatures, including four days where the mercury topped 100, while rainfall was nearly two inches below normal. The following summer was also hot with 36 days of 90 degrees or higher, but rainfall was substantially higher, averaging about three inches above normal. Any low-water problems disappeared in October 1954 when a record 12.06 inches of rain soaked the Chicago area.
A large severe thunderstorm that has a history of producing significant wind damage is raking across southern McHenry, and northern Kane Counties.
Doppler radar indicates that the leading edge of damaging winds will be moving into NW Cook County by 10:30PM.
At 10:25, doppler radar imagery indicates that winds within this storm may have weakened slightly, but this still remains a very dangerous storm with wind gusts of up to 70mph.
Thunderstorms dropped half-inch diameter hail at Elgin just before 10:15 p.m.
A late report from Elgin at 10 30 pm gave the hail size up to 1 inch.
The hail was laasting up to 3 minutes in some areas with wind gusts to 50 mph there.

When the storms passed through the Rochelle area about 9:30 pm this evening semis were reportedly blown over near the intersection of I-88 and I-39.
