US natural gas futures rallied by nearly 2% on Tuesday amid lingering heat and a tightening storage surplus, helping support prices.
The front-month Henry Hub contract and the continuous contract both rose by 1.83% to $2.949 per million British thermal units.
After weeks of milder forecasts, conditions once again turned, with almost the whole country expected to see above-normal temperatures from September 22 through September 28, according to the National Weather Service, keeping cooling gas demand elevated.
This is expected to hit the country's gas storage surplus, "reducing the odds of surpassing 3.9 Tcf (trillion cubic feet) prior to winter," according to the Energy Buyer's Guide.
Gas output held steady at 110 billion cubic feet per day, while demand has largely stayed below that mark over the past week, according to NRG Energy.
US LNG export feedgas, which has continued to rise in recent weeks, is expected to decline to 18.80 Bcf/d on Tuesday, still above the 30-day moving average of 18.71 Bcf/d, according to the Bloomberg LNG Feedgas Model.
