Honestly, if you've spent more than five minutes in Bolingbrook during the winter, you know the drill. One second you're looking at a clear sky over the Promenade, and the next, you're scraping a sudden layer of sleet off your windshield. It's erratic.
Right now, looking at the bolingbrook weather 10 day forecast, we are staring down a classic Illinois roller coaster. As of January 15, 2026, the local atmosphere is basically undecided. We just came off a weirdly warm stretch where it hit 60°F a week ago—breaking records and causing some nasty flash flooding—and now reality is setting back in.
The current temperature is hovering around 14°F, but the northwest wind is making it feel like 1°F. If you’re heading out to the Meijer on Boughton Road, you've probably noticed that "bite" in the air.
The Immediate Outlook: Snow and Slippery Streets
The next few days are going to be a mess for commuters. Thursday starts cloudy with a high of 26°F, but as we move into the evening, the chance of snow showers jumps to 35%. It’s not a blizzard, but it’s enough to make the I-55 merge a nightmare.
Tomorrow, Friday the 16th, things get even stickier. We're looking at a high of 34°F. That’s the danger zone. When the temp sits right at freezing, the snow turns to that heavy, wet slush that freezes into black ice the moment the sun goes down.

- Thursday (Jan 15): High of 26°F, Low of 13°F. Late night snow showers.

By Sunday, the thermometer is basically in a freefall. We’re looking at a high of only 18°F. If you have plans at the Pelican Harbor Indoor Pool, stay inside—the walk to the car is going to be brutal.
Understanding the Bolingbrook Weather 10 Day Forecast Trends
People often think January in Bolingbrook is just "cold," but the nuance is in the wind and the humidity. According to data from the Morton Arboretum and NOAA, January is historically our windiest month, averaging around 18 mph. That wind comes across the flat suburban landscape and cuts right through a standard fleece.
The Polar Push: Early Next Week
Starting Monday, January 19, a dry but frigid air mass settles in.
Basically, the "feels like" temperatures are going to be the real story here.
- Monday: A high of only 18°F. The low? 6°F.
- Tuesday: This is the peak of the cold snap. High of 8°F, Low of 2°F.
- Wednesday: Slightly better at 22°F, but still overcast and depressing.
The humidity is also staying high, around 80% to 90%. In the summer, that’s "muggy." In a Bolingbrook January, that means the air feels heavy and the cold feels like it’s soaking into your bones rather than just hitting your skin.

Why the Forecast Keeps Changing
If you feel like the bolingbrook weather 10 day forecast changes every time you refresh your phone, you aren’t imagining it. We sit in a specific pocket where moisture from the Gulf can sometimes collide with Arctic air dipping down from Canada.
Just look at what happened on January 8th and 9th of this year. We saw record-breaking rainfall (1.92 inches in a single day) and 60-degree weather. That’s unheard of for mid-winter in the Chicago suburbs. When you have that much volatility, the 10-day models struggle to pinpoint exactly when the next "icy mix" will hit.
For instance, Friday, January 23, is currently showing a 30% to 40% chance of a "wintry mix." That's code for "it might be rain, it might be snow, it might be that annoying ice pellets that sound like sand hitting your window."
Survival Tactics for the Next 10 Days
Don't trust a single layer.
Seriously.
With highs swinging from 8°F to 36°F over the next week, you need to be able to shed gear.

- Check your tire pressure: These 20-degree drops will trigger your "low air" light faster than you can say "Hidden Lakes."
- Salt early: Since we have snow followed by a freeze on Friday night, get your salt down before the slush turns to concrete.
- Watch the wind: Monday and Tuesday's wind chill will likely stay below zero for most of the day.
The end of the 10-day window (around January 24) suggests we might climb back up toward the mid-30s. It's a small mercy, but in a Bolingbrook winter, we take what we can get.
Stay inside when you can, keep the wipers up if it's freezing rain, and maybe keep an extra blanket in the trunk. The forecast is looking consistently "gray and cold" with enough snow to keep the plow drivers busy but not enough to cancel school—the worst of both worlds, really.
Actionable Next Steps: Check your vehicle's antifreeze levels today while the temp is still in the 20s. If you’re planning any travel along Route 53 or Weber Road on Friday evening, leave 20 minutes earlier than usual to account for the predicted 1-2 inches of slushy accumulation.
