The data is now official that eastern North Carolina had another winter with below normal temperatures. Meteorologists use the period between December and February as the winter since these 90 days show the coldest averages for the entire year. Combining the average highs and lows would give us 45.1 degrees for the period December through February at the WITN Weather Station. The winter of 2009-2010 was cold with an average of 41.3 degrees or 3.8 below normal. The winter of 2010-2011 that we just finished showed an average of 40.8 degrees or 4.3 below normal. The colder than normal temperatures would indicate increased usage of energy for heating. Now you probably know why your heating bills were higher this year.
