The cumulative Heating Degree Day Anomaly stands at +67 for the Oct 1 - April 25 period (including the current 7-day forecast). That totals about 4,518 HDDs, so it's a mere 1.5% more than normal.
After a mild October, a sharp cold snap quickly raised the anomaly to about +130 by early December, sending gas prices up sharply but briefly. Henry Hub Spot hit a November high of $4.69, then fell to $3.10 in late December.
