Quantifying Weather Effect on U.S. Heating Demand

Weather anomalies continue to run cold, and the actual results for NOAA WEEK 4 (Jan 19-25) were colder by far than their previous forecast.  The current week's forecast is for less intense cold, with Gas Weighted HDD's falling by 4 to 230, but still quite a cold anomaly over the normal 204.

The variance from 2013 is even greater, at +58.
