Right now, we've got a moisture party brewing over the Midwest! Showers are likely overnight, with temperatures holding steady around 70 degrees Fahrenheit. Expect a light southeast wind around 5 miles per hour, and we might see between a tenth and quarter inch of rainfall. But wait - there's a chance of thunderstorms, which means Mother Nature might decide to turn up the volume!

Speaking of volume, here's a little weather joke for you: Why did the thunderstorm go to therapy? Because it had too many emotional outbursts!

Now, let's talk weather science in our Weather Playbook segment. Today, we're exploring the concept of atmospheric instability. Think of the atmosphere like a pot of water on the stove - when it gets heated unevenly, you start seeing bubbling and turbulence. That's exactly how thunderstorms form! The more uneven the heating, the more dramatic the atmospheric dance.

For our three-day forecast: Saturday brings more showers and thunderstorms, mainly in the morning, with temperatures climbing to near 78 degrees Fahrenheit. Saturday night keeps things mostly cloudy with a low around 64 degrees. Sunday continues the wet trend with potential thunderstorms and temperatures near 77 degrees.

A quick local shoutout - if you're planning to catch a Cubs game this weekend, maybe pack a poncho and some waterproof shoes!
