The first snowstorm of the 2025 season in the books. Drivers saw dangerous conditions on the roads as overnight snowfall blanketed the Chicago area.

“The first freeze, which is when the temperature drops at or below 32 degrees, typically occurs between Oct. 11 and Oct. 12 across the Chicago suburbs and Oct. 21 to Oct. 30 in the city and along the lakeshore,” Brett Borchardt, meteorologist for the National Weather Service’s Chicago office, told the Tribune.

Chicago is facing a dangerous lake-effect snow event overnight Sunday into Monday morning. A narrow, but extremely intense band could dump snow at a rate of 3 or more inches per hour - so fast it overwhelms the ability to keep roads clear. If the band pivots and stalls, the city could be looking at double-digit snowfall before midday Monday.

The northern lights might be visible for the second night in a row in parts of Illinois. Here's when to look outside.

Aurora sightings lingered in the Chicago area Wednesday night. Temperatures rise into the 60s Friday and Saturday before cooling Sunday. Rain returns Monday night and Tuesday night.

Passengers were dealing with a double-whammy: weather-related delays and the stress of being caught up in the fourth day of government-mandated flight cancellations amid an air traffic controller shortage and a prolonged government shutdown.

Most of the Chicago area got to experience their first significant snowfall of the season this week, but that week is ending with soaring temperatures.
