Heating/Cooling Degree Day is the total degree difference of the average temperature and 65 degrees F
The rainfall totals in the winter months are water equivalent, which includes all snowfall.
Freezing rain is included in the snowfall totals.
Temperature, rain/snowfall and average wind speed/direction are 30 year averages.
Peak wind data is a 15 year average.
