Nov. 29 (Bloomberg) -- The U.S. Northeast, including New York, may begin to have more seasonal temperatures starting next week and progressing through the middle of the month, according to Commodity Weather Group LLC President Matt Rogers.
In his 6- to 10-day and 11- to 15-day forecasts, Rogers said cooler-than-normal air will move across the U.S. South, while parts of the upper Great Plains may be warmer than normal. He said there is some dispute among computer forecast models.
“These significant differences continue to keep our long- range forecast confidence in a very low state,” Rogers said in a note to clients today from Bethesda, Maryland.
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.
Temperatures in the Northeast have been higher than normal through the past week.
Yesterday, a new all-time high of 70 degrees Fahrenheit (21 Celsius) was set in New York’s Central Park, breaking an old mark from 1990 and 1896, according to the National Weather Service in Upton, New York.
The high temperature in Boston yesterday was 67 degrees, 20 above normal, according to the weather service. It was 70 in Philadelphia, 19 above normal; 69 in Baltimore, 18 above normal; and 63 in Portland, Maine, 19 above normal.
In New York, the normal average temperature for Dec. 7 is about 41 degrees, according to MDA EathSat Weather in Gaithersburg, Maryland. In Boston it’s 38, in Philadelphia it’s 41, in Atlanta it’s 47, in Chicago it’s 30, in Seattle it’s 41 and in Burbank, California, it’s 54.
