February gas futures sprang 50.6¢ higher Wednesday to roll off the board at $7.46 per million Btu as some traders anticipate the current cold blast could result in a record weekly storage pull. In its final session, the contract traded in a $1.927 range as the market awaits confirmation of the precise severity of Winter Storm Fern’s impact on inventory balances. “Market watchers are glued to the freeze-off numbers, watching cumulative losses tip over the 100 billion cubic feet mark,” Price Futures Group analyst Phil Flynn said. “There’s some improvement, but the risk of fresh disruptions still hangs over the market like a winter storm cloud.” Pegging freeze-off losses at 77 Bcf/d since Jan. 20, Gelber & Associates said production had recovered to 101.5 Bcf/d Wednesday. The March contract, which takes over as prompt month Thursday, sank 8.8¢ to $3.732, an extraordinary $3.728 discount to February.
