Warm Start to the Week in Chicago Precedes Cold End to October

After temperatures surge into the 70s on Monday afternoon in Chicago, big changes are in store later in the week.

Following a pretty mild weekend, Monday will likely be the warmest day of the month so far as warm air surges into the area ahead of an approaching cold front.

Much of Monday will turn out dry, but there will be some showers and even a thunderstorm late on Monday afternoon and Monday night as the front moves through. Meanwhile, a gusty wind will persist from Monday into Tuesday.

Behind the front, much of the rest of the week will be dry with some sunshine. Temperatures, though, will be much lower than recent days.

Highs will struggle to get much into the 50s on Wednesday and Thursday. By Friday and Saturday, afternoon temperatures will mostly be stuck in the 40s.
