Oct. 6 (Bloomberg) -- The U.S. from the Southwest to the Northeast will be warmer than normal through next week, according to forecasters.
Above-average temperatures will take hold from southern California across the U.S. to New England and the Canadian Maritimes, according to 6- to 10-day forecasts from MDA EarthSat Weather and Commodity Weather Group LLC.
Temperatures are expected to range least 3 to 8 degrees Fahrenheit (1.6 to 4.4 Celsius) higher than normal, according to the forecasts for Oct. 11 to Oct. 15.
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 biggest variable in next week’s forecast will be what happens with a storm expected to come out of the Gulf of Mexico, said Matt Rogers, president of Commodity Weather in Bethesda, Maryland.
If it combines with another system moving south from Canada, the U.S. East Coast may be cooler because of the rain and clouds.
In the 11- to 15-day outlook for Oct. 16 to Oct. 20, both forecasters call for warming in the central and eastern U.S. Gaithersburg, Maryland-based MDA predicts the highest temperatures will spread across the southern Great Plains and into the Ohio Valley, while Rogers sees the warmest weather in central Great Plains and northern Texas.
