Snowpack conditions in Wisconsin vary greatly depending on the region and elevation. The state's highest mountain range, the Baraboo Range, receives the most snowfall in the state, averaging around 35 to 45 inches annually. The snowpack in this range contributes to the runoff of rivers such as the Baraboo River and the Wisconsin River, which are important for agriculture and water supply.

Other mountainous areas, such as the Blue Mounds and the Kettle Moraine State Forest, also receive significant snowfall. However, the southern part of the state generally experiences less snow accumulation due to milder winter climate conditions.

Wisconsin's winter climate is characterized by cold temperatures, with average highs ranging from the upper 20s to the mid-30s Fahrenheit. Lake-effect snowfall is common near Lake Superior, impacting snowpack conditions in that region.

In terms of snow science, Wisconsin is home to the University of Wisconsin-Madison's Center for Climatic Research, which conducts research on snowpack dynamics and its impact on water resources and ecosystems.

Historically, Wisconsin has experienced severe snowstorms, such as the infamous Blizzard of 1888, which paralyzed the state and caused significant damage. However, in recent years, there has been a general trend of decreasing snowfall in some parts of the state.
