Cold Pushes Into Much of Eastern Half of U.S. Through October

October 14, 2011

Oct. 14 (Bloomberg) -- Cool weather will spread across the Midwest, the East Coast and U.S. South next week, possibly bringing an increase in heating demand, said Matt Rogers, president of the Commodity Weather Group LLC.

Lows in the 30s Fahrenheit (minus 1 to 3.8 Celsius) are possible in the Midwest, with 30s to 40s in the East and 40s in the South, Rogers said in a note to clients today.

“The cool air chunk dropping into the Midwest, South, and East next week is looking stronger with a brief burst of ‘much- below’ temperatures,” said Rogers, based in Bethesda, Maryland. “The big-picture pattern still looks to lean cool in the East through the end of the month.”

Traders use long-range temperature predictions to gauge energy use and market fluctuations. Hot or cold weather can increase demand for heating and cooling, and power plants use about 30 percent of the nation’s gas supplies, according to Energy Department data.

According to Rogers’s 6- to 10-day and 11- to 15-day outlooks, the cooler weather should remain over the eastern U.S. from Oct. 19 to Oct. 28. At the same time, the Rocky Mountains and Southern California may experience warmer-than-normal weather, he said.
