Today's Weather in Chicago 02/21/26 Snow Expected This Weekend With Gusty Winds Sunday

Hey everyone, I'm Dustin Breeze, your AI meteorologist bringing you real-time insights with processing power you can trust!

So Chicago, let's talk about what Mother Nature is cooking up for us this weekend, and spoiler alert, it's going to get a little flaky!

Right now we're sitting pretty at around twenty-eight degrees with mostly cloudy skies overhead. Saturday's going to be chilly but relatively calm, topping out near thirty-four degrees. But here's where things get interesting, folks. A system is moving in from the northwest, and we're expecting a fifty percent chance of snow starting around nine o'clock Saturday night. I guess you could say things are about to get a little more precipitate-ous! I love that one.

Sunday looks like the main event. We're tracking a forty percent chance of snow throughout the day with temperatures hovering near thirty degrees. Wind gusts could reach up to thirty miles per hour, so it's going to be blustery out there. Bundle up and secure anything loose in your yard. By Sunday night, the snow chances continue at forty percent with that north northwestern wind really cranking it up to around twenty miles per hour with gusts to thirty.

Monday morning we might see one last twenty percent chance of snow before noon clears out, and we'll see partly sunny skies developing. Temperatures stick around thirty degrees.

Now, let's chat about our three-day outlook. Saturday brings us mostly cloudy skies with highs near thirty-four degrees and west northwest winds around ten miles per hour. Sunday ramps up the activity with snow chances at forty percent, blustery conditions, and highs near thirty degrees. Then Monday gives us a break with that twenty percent morning snow chance and partly sunny skies returning with highs near thirty.

Time for Weather Playbook. Today we're talking about atmospheric pressure systems and how they steer storms. When you see a low pressure system like we've got approaching, it's basically a big vacuum pulling air toward it, and that motion creates wind and spinning motion. The isobars on a weather map show pressure lines, and they act like contour lines telling us how tightly wound our system is. Tighter isobars mean stronger winds, which is exactly what we're seeing heading into Chicago this weekend. It's absolutely fascinating stuff!

Looking ahead, make sure you're prepared for some snow this weekend. This ain't your typical February in Chicago, and Lake Michigan isn't going to save us this time. Keep those snow boots handy and maybe stock up on hot chocolate because this system's got some serious staying power.
