US natural gas futures stabilized near $3.12/MMBtu on Tuesday, halting a two-day slide, as traders balanced the return of a key Appalachian pipeline against firm LNG feedgas demand and forecasts for continued hot weather.

TC Energy lifted its force majeure on the Mountaineer XPress pipeline in West Virginia on Sunday after completing repairs. The restart will let more gas flow out of the Marcellus/Utica shale region over the next few days, adding supply to a market already digesting near-record production.

That supply headwind has so far failed to push prices materially lower, because two demand-side forces continue to absorb the extra barrels of gas. The first is LNG export demand: flows to the nine major US export plants averaged 18 billion cubic feet per day (bcfd) in September, up from 17.3 bcfd in August. The second is weather: hotter-than-normal temperatures have burned through the storage surplus that accumulated during a strong-production, mild-spring stretch.

Analysts expect inventories for the week ended September 25 to have fallen to 2.4% above the five-year-normal level, down from 2.9% a week earlier — the surplus is eroding week by week.

Underpinning the whole picture is production. Lower 48 output has held elevated at 112.3 bcfd in September, matching the record monthly high set in August.

For the freight and supply chain audience, the gas market's fundamentals matter in several concrete ways. LNG feedgas at 18 bcfd translates directly into sustained tanker loading schedules at Gulf Coast and Atlantic export terminals — more feedgas means more cargoes, keeping slot demand firm for gas carriers through the shoulder season. A stable price around $3/MMBtu, rather than a spike, supports predictable feedstock economics for energy-intensive shippers, from petrochemical producers to cold-storage operators watching fuel surcharges on truckload and refrigerated lanes.

The balance of forces is tight but not bullish-breakout territory. Mountaineer XPress adds Marcellus/Utica supply exactly as LNG offtake rises and heat trims storage surpluses. If the storage overhang keeps shrinking at the current pace — roughly half a percentage point per week — the market could head into the heating season close to normal inventories, a setup that leaves prices sensitive to any further demand surprise.
