LONDON, Jan 4 U.S. natural gas prices plunged on Tuesday amid forecasts that temperatures will be average or higher across most population centres by the middle of January.
Earlier forecasts had predicted colder temperatures would persist through most of January, boosting heating demand.
But the correction in gas prices comes after hedge funds had amassed unusually large bullish bets, helping drive prices up by more than 40 percent in the last two months.
Once some of the frothiness caused by the big build up of hedge fund positions has been blown off, prices are likely to continue trending upwards in 2017.
Futures prices for gas delivered to Henry Hub in February fell on Tuesday by almost 40 cents per million British thermal units, or nearly 11 percent.
Prices for gas delivered in July were down more than 25 cents, or around 7 percent, compared with the previous close.
The trigger for the sell-off seems to have been revised weather forecasts showing temperatures across most of the United States would be higher by mid-January.
The projected weakening of the circumpolar vortex had been expected to allow masses of much colder air to wander south over the United States.
It now appears likely that the worst of the cold will occur over the Eurasian landmass, while temperatures will be normal or above normal over most of North America.
The plunge in front-month prices was the largest for almost three years, but came after they had risen 42 percent since early November.

Hedge funds held a net long position equivalent to 2,927 billion cubic feet of gas on Dec. 27, according to an analysis of data published by the U.S. Commodity Futures Trading Commission.
Fund managers' net position had increased by the equivalent of 1,641 billion cubic feet or 128 percent in just six weeks.
The concentration of positions left the market vulnerable to a correction once prices stopped rising and funds attempted to take some of their profits.
Despite the sell-off, the underlying state of the gas market appears tight, which is a big turn round from the first quarter of 2016. (tmsnrt.rs/2hRUwYg)
U.S. working gas stocks in underground storage declined by 687 billion cubic feet during the final six weeks of 2016, the largest seasonal decline since 2013.
By Dec. 23, stocks were 413 billion cubic feet, or 11 percent, below the level at the same point in 2015, according to the U.S. Energy Information Administration.
Stocks were also 79 billion cubic feet, or 2 percent, below the 2011-2015 average, the first time in 2016 stocks had fallen below the five-year average. (reut.rs/2hRYRuJ)
The enormous glut of gas left at the end of the winter of 2015/16 has been erased by the very low prices which prevailed through most of 2016.
The number of rigs drilling for gas in the United States fell to its lowest level for more than a quarter of a century in August 2016 as producers scaled back work on new wells.
Meanwhile, the combination of above average temperatures from the end of May through September and low gas prices encouraged record gas combustion by electricity producers.
The U.S. gas market has been tightening consistently since April as production has fallen and consumption has soared.
The full extent of the tightening has been masked until recently by the unusually mild start to the 2016/17 heating season. ("U.S. natural gas prices caught in the crossfire", Reuters, Oct. 31 )
Unusually warm weather last summer, which caused gas stocks to rise much more slowly during the injection season, lingered into autumn, causing stocks to start drawing down later than normal. (tmsnrt.rs/2hS1D3a)
Concerns about storage space running out resulted in a sharp drop in prices during the second half of October and the first half of November. ("Hedge funds cut bullish bets on winter fuels", Reuters, Nov 15 )
But the arrival of the first blast of much colder than normal weather in December and a second cold spell forecast in early January has shifted attention back to the underlying market tightness.
Enormous draw downs in gas stocks in the first three weeks of December have underscored just how much tighter the market has become.
Gas stocks fell in December much faster compared with 2015 than can be accounted for by the cold weather alone. (tmsnrt.rs/2hS9WM3)
Stocks fell by an extra 144 billion cubic feet in the first three weeks of December after adjusting for temperatures.
Stocks have now fallen below the five-year average even though heating demand so far this season has been 18 percent below the long-term average. (tmsnrt.rs/2i9V0qF)
Gas drilling has picked up in response to rising prices, with the number of rigs up from a low of 81 in August to 132 at the end of the year, according to oilfield services company Baker Hughes.
The much larger increase in oil-well drilling since May will also increase gas supplies through the production of more associated or casinghead gas.
But gas consumption is also set to rise this year as another 11.5 gigawatts of gas-fired power generating capacity is installed by the end of 2017. ("New wave of power plants is fuelling U.S. gas demand", Reuters, Oct. 4 )
Super-efficient combined-cycle gas turbines (CCGTs) are displacing smaller, older, less-efficient and less-flexible coal-fired power plants. ("Old and worn out, U.S. coal-fired power plants easy prey for gas", Reuters, Nov. 14 )
So gas prices will need to be higher on average during 2017 to sustain increased drilling and curb gas consumption by reducing the number of hours run by CCGTs.
Once some of the speculative froth has blown off the gas market, prices are likely to resume rising. (Editing by Mark Potter)
