You can thank El Nino for likely depriving you of a white Christmas. According to the Climate Prediction Center, northeast Wisconsin has had a white Christmas 61 to 75 percent of the time historically when you look back at data from 1991 to 2020. A white Christmas, defined by the Climate Prediction as having at least an inch of snow on the ground, is a coin flip when you head south of the area and almost a certainty when you head north. Weatherology meteorologist Mike Karow says El Niño is a major factor in why you will likely have a Green Christmas this year.
Karow said temperatures will likely be between 30 and 40 degrees in the week leading up to Christmas.
