Weather Alert: Why This Weekend in Iowa and Illinois Will Be Anything but Sunny

If you’re spending the weekend in eastern Iowa or northwestern Illinois, the Iowa-Illinois Weather Update brings a heads-up: you’ll likely be dodging raindrops. A slow-moving weather system is working its way east, bringing scattered showers across the region. While we’re not looking at severe storms, the persistent rain and cloud cover could put a damper on outdoor plans. It’s not a washout, but you’ll want to keep an umbrella close just in case.

What’s Going On in the Skies?

This stretch of wet weather is being driven by a sluggish front that’s pulling moisture over the Mississippi River. Rain is expected to continue into Sunday across key areas like Cedar Rapids, the Quad Cities, and Rockford. The good news? There’s no severe threat right now—just light to moderate showers with the occasional rumble of thunder. For many, it’ll just be one of those cozy, gray weekends where you might want to stay indoors and enjoy the slower pace.

Temperatures will remain cool and comfortable, with highs in the low to mid-60s and overnight lows dipping into the upper 40s. That cooler air is actually helping prevent stronger storms, which is a small silver lining in the latest Iowa-Illinois Weather Update.

What to Expect

• Driving Conditions: Roads may become slick, especially during bursts of moderate rain. Slow down and stay alert.

• Weekend Plans: If you’ve got outdoor activities scheduled—like kids’ sports, gardening, or barbecues—you may want to have a backup plan.

• Rainfall Totals: Rainfall amounts will generally stay light, but in some spots, totals could creep up enough to lead to minor ponding on roads and lawns.

Looking Ahead

Sunday afternoon should bring a break in the rain, and by Monday, sunshine could return. Expect temperatures to start warming back up early next week, with highs climbing toward the low 70s. Spring in the Midwest always keeps us guessing, but it looks like clearer, brighter days are just around the corner.
