The U.S. East Coast and Ohio Valley are expected to be warmer than normal at the start of December after colder temperatures prevail for most of the next 10 days.
Temperatures may rise about 3 degrees Fahrenheit (1.7 Celsius) along the coast and as much as 8 degrees across the Midwest and eastern Canada from Dec. 3-7, according to Matt Rogers, president of Commodity Weather Group LLC, based in Bethesda, Maryland.
“The cold could be stronger than forecast for the Northeast and mid-Atlantic toward the middle of next week, but it may end faster than previously forecast for the Midwest by late next week,” Rogers said in a note to clients. “That advances the next warm-up into the first weekend of December.”
Meteorological winter starts Dec. 1 while the calendar marks the season change on Dec. 21. The winter months are when the most natural gas and heating oil are consumed, and cooler-than-normal weather in the high-population areas of the East Coast and Midwest helps boost demand for energy to warm homes and businesses.
Before the warmer air arrives, the eastern U.S. and Canada may have temperatures 3 to 5 degrees below normal in the last week of November.
