Weather Roller Coaster

The weather this winter has been somewhat of a roller coaster with its ups and downs. According to Steven A. Ackerman and Jonathan Martin from the University of Wisconsin Madison's department of atmospheric and oceanic sciences, temperatures have not been normal this winter. In November of 2014, temperatures were on average 6.1 degrees cooler than usual. A mild December with temperatures 5.8 degrees above normal followed. And now with January almost over, temperatures have again been below average. It has been 20 years since a cold season has "flipped from below normal to above normal" the writers claim. There is a chance that this winter could be one of those years.
