This weekend in Chicago will be warm (low 80s) with increasing storm chances as the days go on. Saturday looks drier, especially early. Sunday is your "plan B" day — keep indoor activities ready. Winds stay light (5–10 mph), so no big breezes to worry about. Nights stay comfortable in the low 70s.
Q: What does "slight chance" mean?
A: It means less than 30% chance — possible, but not likely. You might see a few drops.
Q: Is 60% rain chance bad?
A: It means rain is more likely than not. It doesn’t mean all-day downpour — just expect some wet weather at some point.
Q: Will it be humid?
A: The forecast doesn’t say, but summer Chicago mornings in the 70s/80s with south winds often feel muggy. Dress in breathable fabrics.
Q: Can I still grill on Saturday?
A: Yes! Morning/afternoon looks great. Just keep an eye on the sky by evening.
Q: Where does this info come from?
A: Directly from the U.S. National Weather Service — the official government weather source.
