Green Bay, Wisconsin – Frost bites hard this morning as doors creak open and breath crystallizes instantly in the air. The New Year begins with true winter muscle, locking northeast Wisconsin in dangerous cold before a messy shift arrives this weekend.
According to the National Weather Service, temperatures near Green Bay sit close to 5 degrees early today, with wind chills dropping below zero. Sunshine helps, but highs struggle to reach the mid-teens. Any exposed skin can feel numb quickly, making cold-weather precautions essential.
Travel impacts stay limited today thanks to dry conditions, though untreated side streets and bridges remain slick. Drivers should allow extra time during the morning commute as cold pavement hides patches of ice.
Clouds increase tonight as temperatures fall near 10 degrees. Saturday brings a subtle change. Highs rise toward the lower 20s, and light snow becomes possible by afternoon. Accumulations look minor, but even a dusting can cause slippery travel given the cold ground.
Saturday night clears briefly, allowing temperatures to fall near 5 degrees again. That reset matters. By Sunday, clouds thicken and highs climb into the mid-20s. Moisture increases late in the day, setting the stage for a more impactful change Sunday night.
Meteorologists are tracking a wintry mix developing by Sunday night into early Monday. Snow may transition to sleet or freezing rain, especially near Lake Michigan. Even light icing can create dangerous road conditions quickly.
Monday turns milder, with highs near the low 30s. A brief chance of freezing rain early may give way to drier weather, but refreezing remains a concern after sunset. Patchy fog may develop Monday night as temperatures hover in the low 20s.
Residents should dress in layers today, limit outdoor exposure, and prepare for changing road conditions this weekend. Winter is firmly in control as 2026 gets underway.
