East Coast May Cool Into Mid-June, Keeping Power Use Down

The U.S. East Coast’s late-May blast of heat may give way to cooler weather through mid-June, potentially keeping air conditioners off and electricity consumption low.

Temperatures from the Canadian Maritimes to the North Carolina-Virginia line may be 3 to 4 degrees Fahrenheit (1.7 to 2.2 Celsius) below normal from June 4 to June 8, said MDA EarthSat Weather in Gaithersburg, Maryland. Seasonal weather may follow from June 9 to June 13.

New York City had a high yesterday of 89 Fahrenheit (32 Celsius), 15 degrees above normal, while Washington had 91, 12 above normal, according to National Weather Service data.

“After yesterday’s impressive first-of-the-year 90s surge on the East Coast, our current forecast shows no more 90s repeats over the next two weeks,” said Matt Rogers, president of Commodity Weather Group LLC in Bethesda, Maryland.

Temperatures in the 80s and 90s or periods of high humidity send people to their air conditioners for comfort, creating extra demand for electricity. The low price of natural gas has prompted many utilities to burn that fuel to produce power instead of coal.

Natural gas declined today on the New York Mercantile Exchange on forecasts for cooler Northeast weather.

The normal average temperature in New York for June 7 is about 70 degrees, according to MDA. It’s 65 in Boston, 73 in Washington, 76 in Atlanta, 82 in Houston, 80 in Dallas, 60 in Seattle and 68 in Burbank, California.
