Natural gas futures turn higher, push toward $4 (by Claudia Assis)
SAN FRANCISCO (MarketWatch) -- Natural-gas futures turned higher in the last stretch of floor trading Wednesday, leaving a multiweek low as other energy products and crude traded higher amid ongoing concerns about unrest in Libya. Natural gas for March delivery (NGH11) rose 5 cents, or 1.4%, to $3.92 per million British thermal units. Forecasts of warm weather in key East Coast consuming markets haven't changed, making gains tenuous, analysts said.
