Wide temperature swings expected in the next 10 to 16 days are a reminder that
Chicago's weather is marching to an autumnal drum. Summery temperatures Friday and
Saturday will yield to cooler air Sunday and then yield further to showery, windy and
much cooler weather Monday and Tuesday. Afternoon readings in the lower 80s Friday
collapse to nighttime temperatures in the lower 40s by the middle of next week. That's
a 40-degree plunge over a four-day period, from 9 degrees above normal Friday to 10
degrees below normal Wednesday. And then another temperature pattern reversal sends
temperatures upward, ultimately carrying readings into the 70s by about Oct. 5.
WINDY, RAINY WEATHER ON EASTERN SEABOARD
Two weather systems, an unnamed disturbance with semi-tropical characteristics and
Tropical Storm Kyle (destined to become Hurricane Kyle), are sending deluges of
wind-driven rain into the eastern United States from the Carolinas to Maine. Interior
areas of the Southeast, especially the Carolinas, need the rain. They've been
experiencing serious drought conditions since February.
