US natural gas futures rose in midday trade on Monday as lower Canadian imports tightened supply, warmer forecasts boosted cooling demand and strong LNG feedgas flows supported prices.
The front-month Henry Hub contract and the continuous contract both rose by 2.44% to $2.90 per million British thermal units.
Canadian imports fell to a two-week low of 4.2 billion cubic feet per day, pulling total supply down to 117.4 Bcf/d, according to Gelber & Associates.
G&A said the decline in imported supply is carrying more weight as warmer weather revisions across the Midwest, South Central and Northeast are expected to sustain cooling demand over the coming week.
NRG Energy said this week's weather is forecast to be warmer than normal across most of the US, with only coastal areas expected to see near-normal temperatures, supporting natural gas demand.
Power-sector gas consumption has also rebounded to 44.7 Bcf/d, Aegis Hedging said, as cooler parts of the country are beginning to generate modest early-season heating demand.
Looking ahead, forecasts indicate temperatures will remain mostly above normal through Sept. 26, although the expected warmth is less extreme than previously projected, Trading Economics said.
Warmer conditions are expected to keep power generators relying more heavily on natural gas to meet higher air-conditioning demand across much of the country, further supporting prices, according to Trading Economics.
LNG feedgas demand is also strengthening. Flows reached a fresh two-week high of 19.8 Bcf/d as deliveries recovered at the Freeport and Golden Pass LNG facilities, Gelber said.
Aegis Hedging said commissioning activity at Golden Pass remained choppy, potentially signaling a slower ramp-up for additional trains at the facility.
On the domestic supply side, US natural gas production remained strong over the weekend but was broadly flat at around 110 Bcf/d. September production is averaging 109.7 Bcf/d, up 2 Bcf/d from September 2025, NRG said.
Natural gas inventories stand at 148 Bcf, or 4.8%, above the five-year average for this time of year. Analysts estimate inventories were about 3.6% above normal in the week ended Sept. 11, Trading Economics said.
