The eastern U.S. and southern Ontario and Quebec may get a burst of warm air by mid-April, MDA Weather Services said.
Average temperatures in the region are expected to climb 5 to 7 degrees Fahrenheit (3 to 4 Celsius) above normal from April 12 to 16, according to Gaithersburg, Maryland-based MDA. In the Appalachian Mountains from Pennsylvania to North Carolina, temperatures may rise 8 to 14 degrees above normal.
At the same time, western Canada and the upper Great Plains may see readings 3 to 4 degrees below normal.
“Models are largely in agreement on the warm pattern,” MDA said in a note to clients. “Confidence is moderate to high in the large-scale pattern but still a bit lower in the finer details.”
The U.S. heating season, when natural gas demand is heaviest, ended last month. April is the start of a transition to warmer weather, when more energy is used to cool, rather than heat, homes.
Until heat builds in the Northern Hemisphere’s summer, the impact of the weather on energy prices is less noticeable. About 50 percent of U.S. households use gas for warmth.
The normal average temperature on April 11 in New York City is 51 degrees Fahrenheit (11 Celsius), according to MDA. In Boston, it’s 47; in Chicago, 47; in Houston, 69; in St. Louis, 56; and in Burbank, California, it’s 62.
