After starting the winter heating season (November–March) below its previous five-year average, Lower 48 working natural gas in storage surpassed its five-year average in mid-December during one of the warmest Decembers on record. However, colder-than-normal temperatures in early January, along with increased liquefied natural gas (LNG) exports and increased power demand compared with last year, have lessened these gains, and working natural gas is again less than the five-year average.
