What’s Happening Right Now?
Think of the atmosphere over Chicago like a shaken-up soda bottle—lots of energy building up, ready to pop. Fox Chicago Meteorologist Kaitlin Cody says we’re looking at multiple rounds of storms today, not just one quick shower.
All hazards are on the table:
- Damaging winds (like a giant invisible fan blowing 60+ mph)
- Large hail (ice balls falling from the sky)
- Brief tornadoes (spinning columns of air—rare but possible)
- Flash flooding (especially tonight when the ground is already soaked)
Today’s Forecast (Sunday, August 9)
| Time | What to Expect |
|---|---|
| Morning | Increasing clouds, warming up |
| Midday → Afternoon | First round of storms possible |
| Late Afternoon → Tonight | Second round – higher flood risk |
| High Temp | Mid 80s (°F) |
ELI5 Explanation: "Mid 80s" means around 84–86°F—warm enough for shorts, but the humidity makes it feel stickier. The storms are fueled by that warmth + moisture.

Important Safety Reminders
KEEP THESE HANDY ALL WEEK
- Enable weather alerts on your phone (Settings → Notifications → Emergency Alerts)
- Have multiple ways to get warnings – phone, TV, weather radio, app
- If a WARNING is issued (not a watch): Go indoors immediately, stay away from windows
- Never drive through flooded roads – 6 inches of water can knock you down, 12 inches can float a car
- Secure outdoor items (patio furniture, trampolines, grills) before storms hit
- Check on neighbors – especially elderly or those with mobility issues
- O’Hare travelers: Check your flight status constantly; delays/cancellations likely
Summary
Chicago is in for a stormy stretch starting today (Sunday, Aug 9) through at least Wednesday.
- Today: Two rounds of storms, flooding risk highest tonight
- Monday–Wednesday: Daily chances for strong/severe storms, mainly afternoons/evenings
- Thursday: Slightly cooler, still cloudy with rain chances
- Friday: First mostly sunny day – finally a break!
- Weekend: Rain chances return Friday night into Saturday
Bottom line: Keep your umbrella handy, your phone charged, and your eyes on the sky. This pattern is stuck like a broken record—storms every afternoon/evening until the pattern breaks late week.
FAQ
Q: What’s the difference between a "Watch" and a "Warning"?
A: Think of it like baking cookies:
- Watch = "Ingredients are out, oven is heating up" → Conditions are right for storms. Be ready.
- Warning = "Cookies are in the oven, timer dinged!" → Storms are happening NOW. Take action immediately.
Q: Why does the flood risk go up tonight?
A: The ground acts like a sponge. Morning/afternoon storms soak it. By evening, the sponge is full—so any additional rain has nowhere to go but streets, basements, and low spots.
Q: Should I cancel outdoor plans for Monday–Wednesday?
A: Have a Plan B (indoor backup). Mornings might be okay, but afternoons/evenings are highest risk. Check radar before heading out.
Q: What does "Ground Stop" at O’Hare mean for my flight?
A: No planes take off or land until it’s lifted (1:30 PM today, but could extend). Even after it lifts, expect delays and cancellations as airlines catch up. Check your airline app constantly.
Q: When will this stormy pattern finally end?
A: Friday looks like the first mostly dry, mostly sunny day. But—rain chances return Friday night. True "pattern break" likely next weekend.
