September Nymex natural gas (NGU23) on Monday closed -0.004 (-0.15%).
Nat-gas prices Monday closed slightly lower on the outlook for cooler U.S. temperatures, which will curb nat-gas demand from electricity providers to power air conditioning. Forecaster Maxar Technologies said cooler temperatures are expected to move into the East Coast through August 4, although heat will persist in the Southwest through mid-August.
