Natural gas futures declined on Tuesday, re-approaching two-year lows although reports of an outbreak of cold January weather was expected to stoke demand for the heating fuel. On the New York Mercantile Exchange, natural gas futures for delivery in January were down 3.34% at $3.092 per million British thermal units during U.S. morning trade. Natural gas futures had found some support on Monday after the U.S. government’s midday Global Forecast System showed “a stronger cold push” in the Midwest. The report also showed lower temperature readings for the Plains, Texas and the Northeast for January 3 through January 7, while forecasts turned colder in the central and northern mid-Atlantic regions for the following five days. Natural gas prices dropped below $3 per million British thermal units last week to the lowest level since September 2012, weighed by mild weather and record production. Approximately 49% of U.S. households use gas for heating, according to the EIA, the statistical arm of the Energy Department.
