US natural gas futures retraced gains in midday trading Tuesday but remained positive as forecasts pointed to persistent late-summer heat and slower production, tightening the market's starting balance.
The front-month Henry Hub contract and the continuous contract both rose 0.35% to $2.906 per million British thermal units.
While gas supplies remained ample, production fell to a two-week low of 111.4 Bcf/d Tuesday, according to Gelber & Associates.
Canadian imports also remained subdued at 4.5 Bcf/d, putting total supply near 116 Bcf/d and giving the market a tighter starting point than recent production highs would suggest.
"The decline is not yet large or persistent enough to signal a lasting change in the supply trend, but it is supporting prices alongside the warmer forecast," Gelber & Associates said.
Aegis Hedging, citing Criterion data, said the weather forecast was unchanged early Tuesday, with temperatures gaining 3 degrees Fahrenheit over the forecast period.
Temperatures are trending back toward the 10-year average in the back half of the outlook, Aegis said, noting that the week ending Sept. 25 is expected to warm by roughly 2 degrees Fahrenheit, extending some cooling demand into late September.
On the export side, US LNG feedgas demand fell by nearly 800 million cubic feet per day Tuesday to 18.8 Bcf/d, led by a decline of more than 500 MMcf/d at Cameron LNG, Aegis Hedging said.
Maintenance at Cove Point's Pleasant Valley facility is scheduled to begin Sept. 19 and typically lasts about 20 days, according to Aegis.
Despite Tuesday's decline, average flows to the nine major US LNG export facilities have risen to 18.3 Bcf/d so far in September, from 17.2 Bcf/d in August, Trading Economics said.
