Freeze Warnings Grip Wisconsin as Temperatures Plummet
7 Oct
Summary
- Freeze warnings in effect across Wisconsin and Great Lakes region
- Temperatures dip below freezing, threatening gardens and crops
- Warmer weather expected to return by the weekend
On October 7th, 2025, a sudden cold snap has gripped much of Wisconsin and the surrounding Great Lakes region. Freeze warnings are in effect as overnight temperatures dip low enough to threaten gardens, crops, and unprotected outdoor pipes.
While the state typically sees its first frost by this time of year, the current temperatures are a stark 360-degree turn from the heat wave that brought record-breaking warmth just three days ago. Across much of Wisconsin, temperatures have dipped just below freezing, with the National Weather Service office in Green Bay warning of mid-20s readings in parts of north-central and northeast Wisconsin.
However, this chilly spell is not expected to last. Nighttime lows are expected to rebound into the upper 30s to low 40s by midweek, and daytime temperatures will continue to reach the upper-60s to mid-70s by the weekend. Overall, Wisconsin is likely to experience a warmer-than-normal, milder fall, though the return of La Niña could make the winter outlook more uncertain, potentially bringing colder temperatures and above-average snowfall to the region.
