Sept. 23 (Bloomberg) -- Natural gas futures fell for a fourth day to the lowest level in almost 11 months as forecasts showed cooler weather in the U.S. Midwest, reducing demand for the power-plant fuel.
Gas fell 0.1 percent as forecasters including Commodity Weather Group LLC in Bethesda, Maryland, said temperatures will be below normal in the Midwest through Sept. 27. Prices may decline next week on sufficient stockpiles, seven of 13 analyst surveyed by Bloomberg said.
“We are in the shoulder season and you aren’t seeing much cooling or heating demand,” said James Williams, an economist at WTRG Economics, an energy research firm in London, Arkansas.
Natural gas for October delivery slid 0.4 cent to $3.701 per million British thermal units on the New York Mercantile Exchange, the lowest settlement price since Oct. 27. Gas fell 2.8 percent this week, the fifth weekly decline in six. Prices have dropped 16 percent this year.
November $3.85 calls, bets that prices will rise, were the most active options in electronic trading. The calls slid 0.3 cent to 0.6 cent per million Btu on volume of 200 lots.
The price difference, or spread, between futures for delivery in October 2011 and January 2012 narrowed 2 cents to 45.8 cents. The contracts represent the difference in price between gas for delivery in the fall, when mild weather reduces fuel use, and the winter, when demand is highest.
The weather pattern is “fairly benign” for the U.S. and Southern Canada with a pattern that generally results in reduced cooling demand, according to Matt Rogers, president of Commodity Weather Group.
The eastern U.S. will see normal temperatures from Sept. 28 to Oct. 2, he said in a note to clients.

Texas will see hotter-than-normal weather in the weekend, he said. Houston and Dallas may reach highs above 100 degrees.
