US natural gas futures rose on short covering and speculation about a polar vortex disruption that could bring colder weather later in November. Front-month December futures traded near $2.93 per MMBtu.
Expectations of colder weather lift US heating demand and gas prices, which raises energy and fertiliser costs for US feed producers. The gain rests on forecasts and short covering rather than a confirmed cold spell.
After 221 past bullish weather events, Natural Gas moved a median +3.3% over 5 sessions (61% higher; middle half -5.2% to +14.0%), and -0.3% over 20.
