Mid-March May Be Warmer in U.S. Northeast, Maritimes

The U.S. Northeast from upstate New York to the Canadian Maritimes may be warmer than normal by mid- March while the center of both countries cools, MDA Weather Services predicts.

Temperatures from New York to southern Maine, including Boston, may be 3 to 4 degrees Fahrenheit (1.7 to 2.2 Celsius) above normal from March 10 to March 14, according to MDA in Gaithersburg, Maryland. Northern Maine, eastern Quebec and the Maritime Provinces may reach 5 to 7 degrees above the norm.

The area from central Canada through the U.S. Midwest and Great Plains to northern Texas may be 3 to 7 degrees cooler than usual during the same period, MDA said.

March 1 is the start of meteorological spring in the Northern Hemisphere and the beginning of the last month of the heating season, which starts in November. Colder weather in the large cities in the Northeast and Midwest can boost energy demand as people seek to heat homes and businesses.

The hemisphere’s astronomical spring starts at 7:02 a.m. New York time on March 20.

The impact of cooler March weather is less than it would be in January because temperatures are significantly higher. January is usually the coldest time of the year.

The normal average temperature in New York City on March 15 is 42 degrees, while on Jan. 15, it’s 32, according to the National Weather Service.

In Chicago it’s 38 on March 15 and 24 on Jan. 15, the weather service said. March accounts for about 17.8 percent of seasonal gas-heating demand compared with 25 percent for January.
