CHICAGO (WLS) -- A Frost Advisory has been issued for most of the Chicago area from 2 a.m. to 9 a.m. Friday.
While the core of the city will stay in low 40s, ABC7 meteorologist Larry Mowry said that temps will drop into the mid 30s outside of the immediate city.
On Thursday morning, commuters at the Jefferson Park transit center said they were not ready for the autumn chill. Many of them wished they had a few more layers on.
The Chicago area has enjoyed some pretty warm weather in the last few weeks. Some areas saw temperatures in the 30s early Thursday morning.
Margarita Rodriguez could see her breath as she waited for her bus. She didn't have time to grab gloves or a hat before she left for work.
"I'm really not prepared. I just grabbed my jacket that I had and threw it on and went on my way to work. It's not that bad, but I'm pretty sure this winter is going to be freezing," Rodriguez said.
"It's not that cold, but it is cold. Yes, it is very cold compared to the weather we had yesterday or last night or the day before. But it's getting cold out here. Can I borrow your jacket?" commuter Ron Collins asked.
