The statement "coldest & snowiest ever" is valid and accurate, at least relative to the last 131 years. That's incredible.
Warmer weather has arrived across Wisconsin and temperatures will approach 60F by Sunday.
The weather at any single point does not necessarily describe the entire state as a whole. The Green Bay record is the most complete of any in Wisconsin. It is not a "HCN" site which means data manipulation was not been needed to complete the record nor adjusted arbitrarily. For example; observation sites in Milwaukee and Madison have changed location since record keeping began. Other considerations including urban heat islands. There are many long, unmanipulated records in the state of Wisconsin that we have not analyzed yet.
