The winter of 2014-2015 was bitter cold with no snow cover until the end of January. The minimum temperature at our house was – 5 deg. F. This is colder than I have seen since living there since 1999. This occurred at night with no snow cover. After mid-January the snow came, and we had significant cover for the balance of the winter.

The winter of 2013-2014 had a minimum temperature of 5 deg. F. However, there was much high wind and very little snow cover. A very hard winter for plants.
