U.S. natural gas futures moved lower in early trading as summer approached its end, with Nymex gas down 2% at $2.857/mmBtu. Dennis Kissler of BOK Financial said cooler forecasts and ample supply were sustaining a sell-the-rallies pattern. Strong U.S. LNG demand, at its highest since April, has not offset heavy storage and expectations for mild fall temperatures. A near-term supportive factor is that this week’s storage report is expected to show a smaller-than-average inventory build.
