Nov. 15 (Bloomberg) -- The eastern U.S. may be warmer than normal next week as the West Coast continues to cool, according to forecasters.
Temperatures in the East may be 3 to 8 degrees Fahrenheit (1.6 to 4.4 Celsius) higher than normal, according to 6- to 10- day forecasts from Matt Rogers, president of the Commodity Weather Group LLC, and MDA EarthSat Weather.
The two forecasts differ on how much warming the New England region can expect. Rogers predicts all of New England will be warmer except Maine, while MDA says temperatures in the six-state region will be seasonal.
“We are seeing more signs of variability this morning that mix in more cooling to the pattern than seen yesterday,” Rogers, based in Bethesda, Maryland, said in a note to clients.
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.
The forecasters rely on a series of computer models to make their weather predictions.
MDA and Rogers differ slightly on where warming will occur in the 11- to 15-day forecasts covering Nov. 25 to Nov. 28.
Rogers predicts warmer air will spread from southern California through the Rocky Mountains and into Canada with the biggest deviations from normal around Hudson Bay.
MDA shifts that pattern eastward, so that the warmth starts in Texas and spreads northeast into New England and the Canadian Maritimes. The largest deviations in the MDA forecast center from upstate New York to Hudson Bay.
The West Coast will be about 3 degrees cooler next week before becoming more seasonal in the 11- to 15-day time period, the forecasters said.
The normal average temperature in New York on Nov. 24 is about 46 degrees, according to Gaithersburg, Maryland-based MDA. 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.
