Nov. 23 (Bloomberg) -- The U.S. Northeast may remain warmer than normal through the first week of December, while parts of the South become cooler than normal or more seasonal, according to forecasters.
Commodity Weather Group LLC President Matt Rogers calls for the Northeast, including most of New York, to be about 3 degrees Fahrenheit (1.6 Celsius) warmer than normal in his 6- to 10-day outlook for Nov. 28 to Dec. 2.
MDA EarthSat Weather predicts Northeast temperatures may be 5 to 7 degrees higher than normal through the same time period, with temperatures in Maine and the Canadian Maritimes rising even higher.
Traders use long-range temperature predictions to gauge energy use and market fluctuations. Hot or cold weather can increase demand for heating and cooling. Power plants use about 30 percent of the nation’s gas supplies, according to Energy Department data.
Rogers said he believes a low-pressure system over the Gulf of Alaska that has been sending warm air into the U.S. won’t dominate the weather pattern after next week, allowing some cooler air to come south.
While he has the Northeast warming, he predicts the Midwest will be more seasonal and the U.S. South will be cooler than normal.
MDA predicts warmer-than=normal weather across a larger part of the U.S. and Canada, including the Great Lakes and upper Great Plains. It does call cooler weather from Houston to Florida.
In the 11- to 15-day outlook, MDA keeps the northern U.S. 3 to 4 degrees above normal with Florida slightly cooler.
Rogers’ forecast for the same time period has the cooler air occupying a much larger part of the southern U.S. from Los Angeles to Mississippi.
For Dec. 2, the average normal temperature in New York is about 43 degrees. It’s 40 in Boston, 44 in Washington, 49 in Atlanta, 32 in Chicago, 39 in St. Louis, 42 in Seattle and 55 in Burbank, California, according to MDA in Gaithersburg, Maryland.
