Temperatures in the eastern U.S. are expected to rise by mid-April, MDA Weather Services said.
From New Hampshire to Florida and as far west as Texas, temperatures are expected to be 5 to 7 degrees Fahrenheit (3 to 4 Celsius) above normal from April 15 to 19, while cooler air dominates the West, said MDA, based in Gaithersburg, Maryland.
April, the first full month of the Northern Hemisphere spring, 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 summer, the impact of the weather on energy prices is less noticeable. About 50 percent of U.S. households use gas for warmth.
The area from Arkansas eastward through Tennessee and into the mid-Atlantic states, including the cities of Washington, Baltimore and Philadelphia, may have temperatures 8 to 14 degrees above normal in April 15 to 19, MDA said.
Temperatures in the Pacific Northwest and western Canada may drop to 3 to 4 degrees below normal, with readings in Alberta 8 to 14 degrees lower than the 30-year average.
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, 62.
