Oct. 10 (Bloomberg) -- The Northeastern U.S. is expected to remain warmer than normal through the middle of October, Commodity Weather Group President Matt Rogers said after a day of record and near-record heat from Pennsylvania to Maine.
Rogers’s 6- to 10-day forecast covering Oct. 15 to Oct. 19 predicts the Northeast will be about 3 degrees above normal, with the northern New England states of Maine, New Hampshire and Vermont even warmer.
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 high temperature in New York’s Central Park yesterday was 84 degrees Fahrenheit (29 Celsius), two degrees below the record for the day set 1916, according to the National Weather Service. The normal high for Oct. 9 is 66 degrees.
The high in Boston was 87, a record for the day, passing a mark set in 1942.
A new high of 85 was set yesterday in Portland, Maine, besting the record of 79 in 1943, according to the weather service. Philadelphia reached 85, one below the record.
In his 11- to 15-day outlook for Oct. 20 to Oct. 24, Rogers predicts the warmth will shift westward into the center of the U.S. with the Northeast becoming more seasonal and the highest temperatures centered on Colorado.
