Lower Temperatures Expected Across Central U.S. Through October

Temperatures across the central U.S. are expected to fall below normal through the end of the month, boosting energy demand, said Matt Rogers, president of Commodity Weather Group LLC.

Readings are forecast to be at least 3 degrees Fahrenheit (1.7 Celsius) lower than the norm for the region, including Chicago and Dallas, from Oct. 19 to Oct. 28, he said today.

“We are still generally seeing increases in national demand again this morning,” said Rogers, who’s based in Bethesda, Maryland.

Below-normal temperatures tend to raise energy consumption as people turn up thermostats to heat homes and businesses.

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

The area affected by cooler air is expected to widen from Oct. 24 to 28, reaching from southern Manitoba to the Gulf of Mexico and eastward to the mid-Atlantic, including Washington and Baltimore, Rogers said.

The normal average temperature in New York for Oct. 20 is about 57 degrees, according to MDA Weather Services in Gaithersburg, Maryland. In Boston, it’s 53; in St. Louis, 58; Chicago, 52; and in Burbank, California, it’s 66.
