US · Published Sep 24, 2026
• According to recent National Weather Service guidance and ensemble models, Chicago's minimum temperature on September 24, 2026, is expected to fall in the mid-50s°F (around 12-13°C).
• Persistent northeast flow and mostly cloudy skies are contributing factors to this forecast.

Impact & Risks

The expected mid-50s°F temperature is unlikely to pose significant risks to residents, but cooler overnight conditions may require adjustments for outdoor activities or attire. If temperatures drop below 48°F, it could lead to a chillier-than-anticipated night, especially for those without adequate heating or insulation. Conversely, a warmer-than-expected outcome above 66°F would provide mild conditions but may still surprise those planning for cooler weather.
