On Wednesday, the area flirted with temperatures near 80 and the high was again expected near 80 on Thursday afternoon. Then it’s bye-bye summer.

After topping out at 78 on Wednesday, temperatures on Thursday are expected to come close to the record high of 79 — as of about 1 p.m. Thursday, the temperature in Chicago was 75 degrees — but then they may drop as much as 40 degrees by the end of the night.

That drop is courtesy of a very strong cold front that will enter the area late in the afternoon, and there’s a chance, though very small, of snow showers over the next few nights.

High temperatures Thursday will continue being unseasonably mild, according to the National Weather Service, with showers likely and a chance of thunderstorms in the afternoon.

The cold front will then sweep across the area late this afternoon and evening, according to the weather service. Winds will shift to the northwest and temperatures will plummet behind the front, possibly as much 15 to 20 degrees in just an hour.

The front should sweep through Rockford by mid- to late afternoon, across the Chicago area toward the evening rush and across northwest Indiana during the early evening.

Low temperatures Thursday night are expected to be in the upper 30s and wind gusts of up to 35 mph are expected to last through early morning Friday, according to the weather service. Lows are expected to remain in the mid-30s through Monday night, and highs are expected to be in the upper 40s through Monday.

Beginning Friday night, there is a chance that snow showers could accompany light rain showers, according to the weather service.

From Friday night through Monday night, as well as Saturday morning, there is a 20 percent chance we could see show showers mixed with light rain. A weather service meteorologist noted though, that there was “a really small chance” of white stuff falling.

Asked if that snow was the sort that would stick to the ground, the meteorologist said, “Oh heavens, no.”
