Sept. 29 (Bloomberg) -- New England and the U.S. West may be cooler than normal next week, while the northern Great Plains and Great Lakes regions warm up, said Matt Rogers, president of the Commodity Weather Group LLC.
The area from the West Coast into the Rocky Mountains, as well as the six New England states and the Canadian Maritimes may be 3 to 5 degrees Fahrenheit (1.6 to 2.7 Celsius) cooler than normal, Rogers said in his outlook covering Oct. 4 to Oct. 8.
“The big picture is fairly similar today with no major changes,” Rogers said in a note to clients.
In his 11- to 15-day outlook, Rogers calls for the eastern U.S. to be warmer than usual with average temperatures rising 3 to 5 degrees above normal for this time of year. The normal average temperature for Central Park today is 63 degrees, according to the National Weather Service.
While the East warms, the northwestern U.S., including northern California, Idaho and Montana, may be 3 to 5 degrees cooler than normal. The average temperature in Butte, Montana for today is 47 degrees, according to the weather service.
The Climate Prediction Center’s 8- to 14-day forecast for Oct. 6 to Oct. 12 calls for the eastern half of the U.S. to have a 40 to 60 percent chance of being warmer than normal. The Great Lakes region has the highest chance of being warmer with average temperatures ranging from 45 to 55 degrees, according to the center.
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.
