Chicago is set to experience a sharp cooldown after an unseasonably warm Saturday, with highs dropping from the 70s into the 40s as a cold front moves through the area. Overnight lows will fall into the mid- to upper-40s, and Sunday will see a 30-35% chance of scattered rain showers, mainly in the morning and afternoon.

Why it matters

The sudden temperature drop and chance of rain could disrupt outdoor activities and plans for many Chicago residents, as the city transitions from an unusually warm spell to more seasonable, cooler conditions.

The details

The cold front will bring a significant cooldown, with Sunday's high occurring early in the day before temperatures steadily decline. Highs will remain in the 40s through Monday, several degrees below the seasonal average of about 50 degrees. The rain showers on Sunday are expected to taper off by the evening, with sunshine returning on Monday and a gradual warmup into the mid-50s by Tuesday.
