Good evening! I'm Aaron Jolly. And this is the Illinois Weather Podcast for Monday, February 23rd. Folks, tonight's cold is just the opening act. Right now you're feeling 25 degrees under partly cloudy skies. Enjoy the calm.. Because Illinois is about to pull off a 30 degree temperature swing in 24 hours. Tonight the bottom drops out. Northern Illinois sinks to 16 degrees. Central Illinois hits 18. Chicagoland holds near 22. That's the kind of cold where your car takes a minute to remember how to start. Then Tuesday rewrites the script entirely. Southern winds kick in hard. And by 3 P.M., northern Illinois jumps to 42 degrees. Gusts could hammer 40 miles an hour around 11 A.M., so anything loose in your yard is going on an adventure. Central Illinois steals the show though. You'll rocket to 50 degrees by 4 P.M. That's nearly 20 degrees above norm ...
