Nov. 18 (Bloomberg) -- The upper Great Plains and western Great Lakes region may be 5 to 14 degrees Fahrenheit (2.7 to 7.7 Celsius) warmer than normal next week, according to forecasters.
MDA EarthSat Weather and Weather Derivatives predict the region has the largest chance in the 6- to 10-day outlook period for temperatures that are much higher than normal. Matt Rogers, president of Commodity Weather Group LLC, also forecasts warmer weather, with the highest temperatures in southern Canada.
“Cool-air availability will be cut off for the most part by a strong Gulf of Alaska low, which will drive the warm Pacific flow across much of the nation,” said MDA’s outlook, which covers Nov. 23 to Nov. 27.
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.
The forecasters rely on a series of computer models to make their weather predictions.
Chicago’s average temperature may be at least 6 degrees above normal Nov. 24 to Nov. 28, which includes the U.S. Thanksgiving holiday, according to David Salmon of Weather Derivatives in Belton, Missouri.
The Northeast, including New York, may be 3 to 4 degrees warmer through Nov. 27, according to 6- to 10-day outlooks from MDA in Gaithersburg, Maryland, and Rogers in Bethesda, Maryland.
MDA and Rogers differ in their 11- to 15-day outlooks, which Salmon doesn’t provide.
MDA forecasts the possibility of the region from the upper Great Lakes to the Northeast warming 5 to 7 degrees above normal, while Rogers says most of that region will be more seasonal with the warmest temperatures in northern Maine.
The normal average temperature in New York on Nov. 24 is about 45 degrees, according to MDA. It is 43 in Boston, 37 in Chicago, 44 in Seattle, 43 in St. Louis, 53 in Dallas, 25 in Calgary, Alberta and 57 in Burbank, California.
