1532 ET - U.S. natural gas futures inch up with a few more weeks of hot weather-driven demand expected to support power-sector use. "Heat remains supportive across most of the South, but its concentration in less population-dense regions limits the national demand impact," Andy Huenefeld of Pinebrook Energy Advisors says in a note. "LNG exports should provide additional demand as fall approaches, but rising supply may absorb a meaningful portion of that increase." Nymex natural gas settles up 0.3% at $2.782/mmBtu.
