Anyone with vacation weekend travel plans through the southern Great Lakes, including southern Wisconsin, should keep an eye on the weather as parts of the region will see daytime snow accumulation. New Year’s Eve, according to forecasters.
“The risk is there” for a blizzard, National Weather Service meteorologist Marcia Cronce told Sullivan. “It will be an effective snowmaker. We have cold air in place with a lot of humidity coming from the south.”
The question is where the storm will head. If it veers south, southeastern Wisconsin would likely only see a dazzling snowfall. If it veers north, southeast Wisconsin would be in the thick of the action.

“We’ve been monitoring this for several days,” Cronce said. “As for the Wisconsin part, we just don’t know ‘so far’ where the most snow will fall.
“I’m not sure who will get the most out of it, but it will definitely impact travel” somewhere in the upper Midwest on New Year’s Day, Cronce added.
“It’s important to pay attention to the forecast” in the coming days, especially if you have travel plans this weekend, she said.
Once the storm passes through the region, very cold air will follow.
For southern Wisconsin, Sunday morning lows appear to be single digits above zero east and single digits below zero west. Gusty northwest winds will bring wind chills between minus 10 and minus 20, with the coldest readings west of Madison, the weather service said.
