Here is a crazy stat...over the last 110 years there have only been 7 years, where there was no snow for Christmas (1913,1923,1943,1960,1979,1994, and 2002)...as you can see the last time we had a Brown Christmas was 21 years ago (this data all comes from Rhinelander, as it's the only location in our neck of Northwoods that has kept historical weather records)
Historically, a "white" Christmas (an inch or more of snow on the ground Christmas morning) occurs 52% of the time at Two Rivers, 60-70% of the time at Kewaunee and Manitowoc, 65-75% of the time in Green Bay and the Fox Valley, 85-95% in Wausau-Wisconsin Rapids-Stevens Point, and over 95% of the time in Rhinelander and far north-central Wisconsin. Lac Vieux Desert in Vilas County has nearly a 100% chance of a "white" Christmas.
The chances of a "white" Christmas this year are slim as there is no snow cover across much of the area and very mild conditions expected Christmas Eve and Christmas Day. Record or near record high temperatures are expected on Christmas Day with readings in the middle 40s to lower 50s. These readings are about 20 degrees above the normal high. The low temperatures on Christmas morning will be in the middle 30s to lower 40s, or some 5 to 10 degrees above the normal high for the date. In addition, rainfall amounts of a quarter to three quarters of an inch are expected Christmas Eve into Christmas Day.
