Low Temperatures Will Linger in U.S. East Into December

Temperatures are expected to fall across the eastern U.S. later this week and stay down through the start of December, according to Matt Rogers, president of Commodity Weather Group LLC.

Readings from Texas to the Great Lakes and then east into New England, including Houston and Chicago, may be 8 degrees Fahrenheit (about 4 Celsius) below normal from Nov. 23 to Nov. 27, Rogers wrote in his forecast today. Temperatures will be 3 to 5 degrees lower along the East Coast, including New York.

Cold may fluctuate along the East Coast this week before gripping the region by the weekend, Rogers said in an e-mail interview. “Pretty impressive cold push for late November,” he said from Bethesda, Maryland.

Below-normal temperatures, especially in Eastern and Midwestern cities, tend to increase energy consumption as more people heat homes and businesses. November marks the start of the U.S. heating season, when natural gas demand peaks.

Power generation accounts for 32 percent of U.S. gas use, according to the Energy Information Administration, the Energy Department’s statistical arm. About 49 percent of all homes use the fuel for heating.

Across most of the eastern U.S., readings are expected to stay about 3 degrees below normal while reaching 5 degrees lower in the South from Nov. 28 to Dec. 2, Rogers said.

The normal average temperature in New York on Nov. 27 is about 45 degrees, according to MDA Weather Services in Gaithersburg, Maryland. In Boston, it’s 42; in St. Louis, 41; Dallas, 52; Houston, 59; Chicago, 35; Burbank, California, 57; and in Calgary, it’s 24.
