Aug. 20 (Bloomberg) -- Natural gas futures slid in New York for the second time in three days on speculation that mild weather will expand a supply surplus of the fuel over the five-year average.
Gas dropped 0.5 percent as the median of eight analyst estimates compiled by Bloomberg predicted government data Aug. 22 would show supplies rose by 71 billion cubic feet last week. The five-year average gain is 56 billion. MDA Weather Services said temperatures may be mostly normal or below-normal on the East Coast from Aug. 25 to Aug. 29.
“The market is definitely going to be well-supplied from a historical viewpoint,” said Phil Flynn, a senior market analyst at Price Futures Group in Chicago. “We’re going to see a storage number that surprises to the upside, which will be very bearish.”
Natural gas for September delivery fell 1.9 cents to settle at $3.444 per million British thermal units on the New York Mercantile Exchange. Trading volume was 5.6 percent below the 100-day average at 2:37 p.m. Prices are up 24 percent from a year ago.
The discount of September to October futures widened 0.5 cent to 2.9 cents. October gas traded 39.6 cents below the January contract, compared with 38.9 cents yesterday.

“We expect the supply side of the equation to continue its healthy pace, led by unprecedented plans for infrastructure growth and de-bottlenecking of production,” Jan Stuart, head of energy research at Credit Suisse in New York, said in a note to clients today.
Lower-48 state natural gas output was little changed in May as new wells began operating in the Northeast’s Marcellus shale formation while Wyoming production declined during scheduled maintenance, government data showed last month.
