A Cold Start to December

Courtesy: icecap.us
The average temperature through the first 16 days of the month at the Rockford airport sits at 8.2 degrees BELOW average! The Stateline, along with most of the central and eastern US (as shown on the graphic at left), have been well below average temperature-wise for the first half of the month. A big reason for this is a blocking high over Greenland. This high doesn't let the storm track through the North Atlantic Ocean, which forces cold air southward across the eastern United States. In addition, our snowfall has been exceeding average as well. Our total to-date is 10.0", which is 5.2" above average.
