“Winter Isn’t Over”: NatGas Soars As Another Cold Blast Targets US East

U.S. natural gas futures surged the most since late October as one energy trader warned that “winter isn’t over,” with another wave of cold air set to spill into the eastern half of the Lower 48 early next week. The upcoming cold blast arrives even as much of the U.S. enjoys a brief warm-up following an early-month polar vortex that plunged large parts of the U.S. East into Arctic-like conditions.

“Winter isn’t over yet. Here are forecast anomalies for this time next week showing a large area of unseasonably chilly temperatures across the major population centers of the Eastern US,” energy trader Celsius Energy wrote on X.

Celsius Energy noted, “Near-term #natgas demand will be quite volatile with very bearish daily storage withdrawals under +5 BCF/d through this weekend surging to nearly -30 BCF/d by this time next week, more than double the 5-yr avg. In general, these projections have improved considerably.”

By late afternoon Tuesday, NatGas futures are up nearly 10%, the largest intraday jump since October 30′s 17% price spike. Prices are trading around $4.365 per MMBtu.

Looking at Heating Degree Days for the Lower 48 – the weather-based measure of US heating demand -the index is projected to surge well above the 30-year average early next week and remain elevated through year-end.

Cold is returning to the eastern half of the Lower 48. Time to stack the firewood and get the gas-powered snowblower ready.
