Chicago First Freeze Still Missing at O’Hare: Friday’s Cold Night and Car Checks for DuPage Drivers
The Chicago first freeze is running more than three weeks late, but the wait may be nearly over. As of Wednesday morning, November 11, Chicago O’Hare had not recorded a temperature of 32°F or lower this fall, according to National Weather Service daily data. Now the NWS Chicago forecast calls for lows in the upper 20s on Friday night in both DuPage County and northern Cook County, along with a slight chance of the season’s first snow showers Thursday evening. For drivers, that means frosty windshields, lower tire pressure and slower starts are about to become part of the morning routine.
O’Hare is running late
NWS Chicago’s normal first-freeze table (1991–2020 climate normals) lists October 19 as O’Hare’s normal date for the first autumn reading of 32°F or lower. O’Hare’s daily records show no reading at or below freezing since September 1. The closest call came on Saturday, November 7, when the official low was 33°F. Last year’s first freeze at O’Hare came on November 9, and the latest first freeze on record in Chicago is November 24, 1931, so this fall is late but not record-setting.
The suburbs have already had a taste. On that same Saturday morning, preliminary NWS observations showed DuPage Airport in West Chicago dipping to about 31°F and Aurora Municipal Airport, just west of Naperville, to about 26°F, while O’Hare stayed just above freezing. Outlying airports often run colder than O’Hare on clear, calm nights.
The forecast: showers, then a colder weekend
The NWS Chicago zone forecast for DuPage County, issued at 9:31 a.m. Wednesday, calls for showers today with highs in the mid 50s, then a breezy Thursday with highs only in the mid 40s and north winds gusting up to 30 mph. Thursday night brings a slight chance of rain and snow showers and lows in the lower 30s. Friday night and Saturday night are forecast to be mostly clear with lows in the upper 20s. The northern Cook County forecast, which covers the O’Hare area, also shows lows in the upper 20s Friday night.
In its forecast discussion, NWS Chicago says the colder air could give some areas their first snowflakes of the season, with the heaviest lake-effect precipitation expected mainly in northwest Indiana. Forecasters note that mild ground temperatures should make it difficult for slush to build up on paved surfaces, and they expect a warming trend early to mid next week. O’Hare has recorded no snow so far this season. Forecasts change, so check the latest NWS forecast before Friday.
Cold-morning checks NHTSA recommends
NHTSA’s winter driving tips page is the practical checklist for the first hard-frost mornings. The agency notes that in 2024 there were 365 fatal traffic crashes and an estimated 24,383 injury crashes when snow or sleet was falling at the time of the crash. Its tire advice is short: “As the outside temperature drops, so does tire inflation pressure.”
- Tires: Fill each tire to the manufacturer’s recommended pressure from the driver’s side door-frame label or owner’s manual, not the maximum number on the tire. Check them cold (not driven for at least three hours), look for uneven wear, and keep tread at least 2/32 of an inch, which you can check with NHTSA’s penny test.
- Battery: NHTSA says battery power drops with the temperature, and gasoline and diesel engines need more battery power to start in the cold. Electric and hybrid vehicles can lose driving range. Have a mechanic check the battery, charging system and belts.
- Washer fluid and wipers: Fill the reservoir with high-quality winter fluid with de-icer, test the defrosters and wipers, and replace worn blades.
- Lights: Check headlights, brake lights, turn signals, emergency flashers and interior lights.
- Stock the car: NHTSA lists an ice scraper, snow brush or shovel, jumper cables, a flashlight, blankets, and a phone charger among the items to carry. It also suggests keeping the gas tank close to full.
This week is also Illinois Winter Weather Preparedness Week (November 9–13, 2026) on the National Weather Service calendar. NWS Central Illinois and the Illinois Emergency Management Agency remind drivers to make sure the car is in good operating condition, to carry a storm kit, and to never leave the motor running in a vehicle parked in an enclosed or partially enclosed space, such as a garage.
Clearing frost without adding a new dent
Here’s our take from the shop floor. Once freezing mornings become routine, we start seeing more small damage: parking-lot door dings from bulky coats and hurried doors, scratches from improvised scrapers, and dents where someone leaned hard on a frozen panel. That is not a forecast, just the pattern cold, rushed mornings tend to bring.
- Use a real scraper. Credit cards, keys and metal tools can scratch paint and trim. Clear every window and both mirrors, not just a peephole on the windshield.
- Ease frozen doors open. Give seals a few seconds after unlocking and open the door gently instead of yanking it.
- Leave room in the lot. Winter coats make doors swing wider. A little extra space helps protect your car and the one next to it.
- Look for new dings in good light. Small door and fender dents are easy to miss. Our guide to the top causes of car door dent damage covers common parking-lot patterns, and many shallow dents with intact paint are candidates for paintless dent repair.
What this means for DuPage drivers
Whether or not O’Hare makes it official on Friday night, the forecast points to some of the coldest mornings of the season so far for DuPage driveways. Use the time before Friday night to check tire pressure, top off winter washer fluid and put an ice scraper in the car. For the bigger seasonal picture, see our report on NOAA’s 2026–2027 winter outlook for Chicagoland. If a door ding or crease has already appeared, dent and scratch repair and paintless options are worth a look, and drivers across our service areas can ask about collision repair when the damage goes beyond a shallow dent.
Our team at EZ Tech Paintless Dent Removal & Collision is happy to look at any new dings or scrapes and walk you through your options.
