Green Bay, WI – A major pattern change arrives early this week across central and northeast Wisconsin, bringing rain on Monday and a transition to snow Tuesday night into Wednesday, according to the National Weather Service in Green Bay.
According to the agency, light rain develops Monday afternoon and evening, spreading across the region and continuing into Tuesday. As colder air filters in behind the system, precipitation will shift to a rain/snow mix Tuesday, eventually changing to all snow by Tuesday night. Snow is expected to linger into Wednesday morning before tapering off.
Forecasters note that all locations have a chance to see at least some snow, but accumulation is most likely north of a Tomahawk-to–Iron Mountain line. Areas in Vilas County may see the highest totals, especially where lake-effect enhancement becomes possible. Travel impacts could develop late Tuesday night and Wednesday morning across the Northwoods.
Communities including Rhinelander, Wausaukee, Crandon, Eagle River, and Florence are more likely to experience measurable snowfall, while Green Bay, Appleton, Oshkosh, and Manitowoc may see lighter amounts or mainly rain before the transition.
The National Weather Service advises that timing and snowfall totals may shift as new data arrives, but early indicators show a classic late-November setup with marginal temperatures and a gradual changeover process. Roads may become slick overnight Tuesday in the far north, particularly on untreated surfaces.
Another update is expected Monday as confidence in snow timing and amounts increases.
