This week’s weather in the U.S. Northeast may be milder than both the norm and the same week last year, according to the U.S. Climate Prediction Center’s weekly heating degree days forecast.
The gas-weighted heating degree days figure for the six-state New England region through Nov. 12 is expected to be 115, or 33 below normal and 37 lower than in 2010, according to the center. The mid-Atlantic region is predicted to have 122, 28 fewer than normal and 33 below last year.
Heating degree days, calculated by subtracting the daily average temperature from a base of 65 degrees, are designed to show energy demand. Higher values mean cooler weather and more energy being used to heat homes and business.
Energy-weighted degree days give more value to areas where there are higher populations using either oil, gas, or electricity to stay warm.
The electricity-weighted heating degree days forecast for New England is 115, 35 lower than normal and 38 below last year. In the Middle Atlantic, the prediction is also for 115, which is 26 below normal and 32 lower than last year, according to the center in Camp Springs, Maryland.
The home-heating-oil value for New England is 122, 35 below normal and 34 lower than last year. For the mid-Atlantic, it’s 113, or 29 below normal and 34 below last year, the climate agency forecasts.
For the U.S. as a whole, the gas-weighted heating degree days value is forecast to be 107, or 15 below normal and 1 higher than last year. The predicted oil-weighted value is 117, or 26 below normal and 24 less than last year. The electric-value is 77, or 8 below normal and 5 below last year.
