On Thursday, October 17, 2025, Chicagoland enjoyed a mild autumn day with highs in the upper 60s to low 70s. The pleasant weather is set to continue into Thursday night, with partly cloudy skies and lows in the mid-50s for northeast Illinois and low 50s across northwest Indiana.
However, the forecast for the upcoming weekend paints a different picture. Friday, October 18, 2025, will bring increasing cloud cover and temperatures soaring into the mid-70s. Southerly winds will also become gusty, likely gusting up to 25 mph by midday and into the afternoon.
The pleasant conditions will be short-lived, as several rounds of rain and storms are expected to move through the area from late Friday night through at least midday Sunday, October 20, 2025. Many areas will likely end up with an inch or more of rainfall, though flood concerns are low given the two-day duration of the event. Temperatures on Saturday will be in the lower 70s, but a strong cold front will usher in much colder air for Sunday, with highs only reaching the upper 50s.
