Natural gas tumbled the most in 15 weeks as revised forecasts showing an unusually warm start to December signaled reduced demand for heating fuels.
Futures dropped as much as 4.6 percent after companies including Commodity Weather Group LLC predicted above-normal temperatures for the lower 48 states over the next six to 10 days. Gas rose to a 13-month high last week after forecasts showed colder weather in early December and a government report showed a bigger-than-expected inventory decline.
“A little bit of cold that we had is coming to a quick end,” said Dominick Chirichella, senior partner at the Energy Management Institute in New York. “If the weather does turn out to be warmer than normal, we could see” more gas additions to stockpiles.
Natural gas for December delivery fell 15.7 cents, or 4 percent, to $3.744 per million British thermal units at 11:25 a.m. on the New York Mercantile Exchange after dropping 18.1 cents to $3.72 in the biggest intraday percentage decline since Aug. 10. Gas is up 5.7 percent from a year ago.
The futures climbed to $3.933 during the previous trading session, the highest intraday price since Nov. 1, 2011. Electronic trading volume was 147,008 contracts today at 11:28 a.m. compared with about 110,000 at the same time on Nov. 23.
“The perception is that the market was a bit overbought last week” amid low volume because of the U.S. Thanksgiving holiday, said Bob Yawger, director of the futures division at Mizuho Securities USA Inc. in New York. “It looks like the drive to $4 has definitely stalled for the time being.”
December may start much warmer than usual across the U.S., with highs possibly reaching into the 60s Fahrenheit (15 to 20 Celsius) in the Midwest and along the East Coast, said Matt Rogers, president of Commodity Weather Group in Bethesda, Maryland.
Average temperatures from Dec. 1 to Dec. 5 may be 5 degrees above normal in the East and as much as 15 degrees higher across the Midwest, including Chicago, Rogers said.
“After cool conditions linger in the Midwest and East this week, a strong warm-up is still slated to expand across the nation,” Rogers said. The warm weather won’t dominate December as a whole, Rogers said in a note to clients today.
By Dec. 6, temperatures across the northern Great Plains and the South are expected to return to seasonal levels while remaining about 5 degrees above normal in the U.S. Northeast, Rogers said.
The low in New York on Dec. 3 may be 46 degrees Fahrenheit (8 Celsius), 10 above normal, according to AccuWeather Inc. in State College, Pennsylvania. The low in Chicago may be 39 degrees, 12 more than the usual reading.
Heating demand in the lower 48 states will be 53 percent below the seasonal norm from Dec. 2 through Dec. 6, data from Weather Derivatives, show. Demand was 18 percent below normal in the week ended Nov. 24, the Belton, Missouri-based forecaster said.
About 50 percent of U.S. households use gas for heating, according to the Energy Department.
U.S. gas stockpiles fell by 38 billion cubic feet in the week ended Nov. 16 to 3.873 trillion, the department said. The five-year average change for the week was a gain of 3 billion.
Inventories in the so-called producing region in the south- central U.S. were cut by 7 billion cubic feet because one or more producers reclassified supplies from working gas, or stockpiles available for delivery, to base gas, or supplies needed to maintain adequate pressure, the department said.
Supplies probably fell by 5 billion cubic feet last week, based on warmer weather, and may show small injections the following two weeks if temperatures don’t drop, Chirichella said.
The five-year average decline for the week ended Nov. 23 is 18 billion cubic feet. The department is scheduled to release its stockpile report for the week on Nov. 29.
While the market has gapped lower today, the uptrend for gas futures is intact as long as prices hold above the $3.50-to- $3.60 support level, Chirichella said.
