Late Winter 2014-2015 Report: Mild Temperatures Lead to Exceptional Cold
Dr. John Young, Director & Dr. Edward Hopkins, Climatologist
This season has had two faces, with the first month of meteorological winter (December) warmer than normal, and now a very cold final month of February. Taking into account computer model projections of a continuing "polar vortex" jet stream pattern, February averaged 10-12 degrees below normal, similar to the exceptional February 2014, and was the coldest in the past 79 years for Madison and Milwaukee.
Ice: Unusual for Madison Lakes, Approaching Exceptional for Great Lakes
Madison Lakes- The two largest ones (Mendota and Monona) closed about two weeks later than average due to the abnormally warm December, while the smaller Lake Wingra closed two weeks earlier due to the abnormally cold November. See our Madison Lakes Ice Summary website for details.
Great Lakes- In mid- February their average ice cover increased rapidly beyond its normal maximum value for the season. On March 2, the average for all lakes was 88%, and Lake Michigan had about 75% coverage. In comparison, last winter's exceptional March ice cover was 92.5%. Great Lakes ice cover maps are updated daily by NOAA's Great Lakes Environmental Research Laboratory.

The data for these products come from the U.S. Cooperative Network, augmented by observations from NWS and FAA sites. These cooperative sites are operated by volunteer observers using approved instruments and observing techniques. Their efforts that provide sufficient data to generate these products are greatly appreciated.
