Central U.S. Temperatures May Be Above Normal through Next Week

November 17, 2011

Nov. 17 (Bloomberg) -- The central U.S. may remain warmer than normal through next week, while New England has more seasonal temperatures, according to forecasters.

Temperatures in Chicago may be as much as 5 degrees Fahrenheit (2.7 Celsius) above average from Nov. 22 to Nov. 26, according to the 6- to 10-day outlook by Commodity Weather Group President Matt Rogers. Weather Derivatives meteorologist David Salmon’s forecast for Chicago predicts temperatures 2 to 6 degrees higher than normal.

New York may be 3 degrees above normal, while New England has seasonal weather, according to Rogers, in Bethesda, Maryland. Salmon, based in Belton, Missouri, predicts temperatures will be about 2 degrees above normal in New York, with most of New England seasonal except for Maine, which he said may be cooler.

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.

The forecasters rely on a series of computer models to make their weather predictions.

Rogers’s 11- to 15-day outlook covering Nov. 27 to Dec. 1 is for warmer-than-normal temperatures to spread from the Rocky Mountains, across the northern U.S. and Canada into upstate New York, New England and the Canadian Maritimes.

Salmon didn’t provide a comparable forecast.

The normal average temperature in New York on Nov. 24 is about 46 degrees, according to Gaithersburg, Maryland-based MDA EarthSat Weather. The normal average is 43 in Boston, 47 in Washington, 51 in Atlanta, 36 in Chicago, 53 in Dallas, 44 in Seattle and 58 in Burbank, California.
