Rogers forecasts temperatures about 3 to 5 degrees Fahrenheit (1.6 to 2.7 Celsius) lower than normal throughout California and the Pacific Northwest in his 1- to 5-day, 6- to 10-day and 11- to 15-day forecasts covering today until Nov. 17.
“The overall big picture for the 6- to 15-day is very similar to yesterday’s story, with colder weather in the West and warmer conditions in the Midwest and East,” Rogers said today 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.
Rogers said he expects the U.S. Midwest and East to remain 3 to 5 degrees warmer than normal from Nov. 8 to Nov. 15. After that there are indications among computer models that colder weather will start to filter into the region.
The average temperature for this weekend in Seattle is about 47 degrees, while in Burbank, California it is 62, according to MDA EarthSat Weather in Gaithersburg, Maryland. In New York, the normal is about 51, in Boston 48, Chicago 45 and Dallas about 61.
