January Nymex natural gas (NGF26) on Monday closed down sharply by -0.377 (-7.13%).
Jan nat-gas prices plunged on Monday after updated weather forecasts showed US temperatures warming mid-month, potentially curbing nat-gas heating demand. Forecaster Atmospheric G2 said that the forecast shifted slightly colder over he eastern and southern US for December 18-22, but noticeably warmer elsewhere. Also, other weather models support a broad-scale warmer risk as cold air is confined to Canada.
