Morning fog; slight chance of afternoon storms, showers – NBC Chicago

Patchy, dense fog started the Chicago forecast early Monday morning, with several areas of low visibility, the NBC 5 Storm Team said.

According to NBC 5 meteorologist Alicia Roman, visibility was particularly reduced in Aurora, DeKalb and Romeoville.

Patchy dense fog has developed over parts of interior northern Illinois. Be prepared for sudden changes in visibility if traveling before ~7am, especially in rural areas. Slow down and switch on low beams if you encounter fog during the first part of your commute #ILwx

“Spotty, dense fog has developed over portions of interior northern Illinois,” a National Weather Service message to the X early Monday morning said. “Slow down and switch on low beams if you encounter fog during the first part of the commute.”

The fog was expected to clear later Monday morning, Roman said, setting up a mostly to partly sunny day with some clouds.

“A fine summer’s day,” said Roman.

Highs Monday were expected to be in the 80s, but cooler along the lake. Monday would also see a low chance of rain or storms in the afternoon hours, Roman said, with higher chances of rain and storms Tuesday and Wednesday.

Expect near-seasonal temperatures to continue this week. A stray shower or storm cannot be ruled out today although better coverage is expected north of I-80 late Tuesday and again Wednesday. Dry conditions then prevail for the rest of the week. #ILwx #INwx pic.twitter.com/zyBjvpIw2S
