Natural gas futures advanced for a third day as sweltering weather blanketed the U.S. Northeast, boosting demand from power plants to run air-conditioners.
Temperatures may be higher than average across the Northeast, Great Lakes region and South through Aug. 2, MDA Weather Services said. Philadelphia may reach 94 degrees Fahrenheit (34 Celsius) Wednesday, 7 above normal, according to AccuWeather Inc.
“These kinds of conditions produce a heavy cooling-demand load because of the humidity,” said John Kilduff, a partner at Again Capital LLC in New York. “Traders are wondering if this portends a hot August.”
