Investing.com - Natural gas futures declined on Friday, as forecasts for mild weather across key consumption regions of the U.S. in the week ahead dampened demand expectations for the fuel.
On the New York Mercantile Exchange, natural gas for delivery in September shed 1.5 cents, or 0.53%, to end the day at $2.798 per million British thermal units.

Updated weather forecasting models released Friday pointed to cooler weather across the Great Lakes, Northeast and Northwest-regions through August 20.
Losses were limited as forecasts showed that most parts of the central and southern U.S. remained engulfed by hot temperatures.
