Chicago will ride a temperature roller coaster in the coming seven days but precipitation will be practically nonexistent. Near normal temperatures Wednesday give way to warmer readings Thursday and then much cooler temperatures — the coolest of the season so far — Friday and Saturday. Readings begin to moderate Sunday, then push into the lower or middle 70s on Monday and Tuesday.
All of these temperature changes occur with little or no rain, although a few brief showers might occur late Thursday and Friday.
On Oct. 14, 1984, dense fog contributed at 118-vehicle accident on Interstate 94 just south of Milwaukee. It was the seventh day of an eight-day stretch of dense fog. The visibility at the time of the accident was reportedly near zero.
