AccuWeather.com reports temperatures will rise nearly 50 degrees across parts of the Midwest between this morning and Tuesday afternoon.

Expert Senior Meteorologist Elliot Abrams says that residents of Chicago will go from wearing sweaters Monday morning to feeling sweaty Tuesday afternoon as temperatures rise to nearly 15 degrees above normal.

This dramatic change will occur thanks to a strong warm front which will surge across the area late tonight.

A gusty south-southwest wind ushering in unseasonably warm air for Tuesday will create one of the more dramatic temperature changes to ever occur in May.

After O'Hare International Airport fell to a low of 36 degrees Monday morning, temperatures will rise to around 84 degrees Tuesday afternoon, a difference of 48 degrees in just over 24 hours.

A huge temperature swing within such a short time frame is quite rare for the middle part of May. A change like this is more likely to happen in March or early April when the temperature difference across the country is greater than what it is currently.

In fact, according to the National Weather Service in Chicago, Ill., the most dramatic one-day temperature change in May for Chicago was 50 degrees which occurred on May 1, 1992.

This warm-up could challenge that record. The second most dramatic May warm-up was 49 degrees which occurred on May 17, 1984.

The dramatic warm-up isn't limited to just Chicago. Residents across the Midwest are subject to these very warm, and in some cases, record-challenging temperatures.

The extreme temperatures won't last all that long as a cold front slides through the area Tuesday night into Wednesday.

It will usher in a slightly cooler, but still above average, air mass for the Midwest for the middle of the week. Highs on Wednesday will be back down near 80 for Des Moines, Minneapolis, Omaha and Chicago.
