Nov. 1 (Bloomberg) -- The U.S. East may be warmer than normal through mid-November while the western half of the country has colder weather, according to Matt Rogers, president of Commodity Weather Group LLC in Bethesda, Maryland.

Temperatures in the East are expected to be about 3 degrees Fahrenheit (1.6 Celsius) higher than average from Nov. 6 to Nov. 10, according to Rogers’s 6- to 10-day forecast. They may rise to 5 degrees warmer in the Northeast from Nov. 11 to Nov. 15, his 11- to 15-day outlook predicts.

California and the Pacific Northwest are expected to be about 5 degrees cooler than normal through Nov. 15, Rogers said.

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.

In early November, the normal average temperature in New York City is about 51 degrees. It’s 47 in Boston and Seattle, 50 in Philadelphia, 52 in Washington and 61 in Burbank, California, according to MDA EarthSat Weather in Gaithersburg, Maryland.
