The last cold snap of a weather pattern that has kept temperatures down and contributed to a series of late-winter snowstorms will push through the eastern U.S. this week.
Temperatures across the eastern U.S., with the exception of New England and Florida, are expected to range from 3 to 5 degrees Fahrenheit (2 to 3 Celsius) below normal today until April 5, according to Matt Rogers, president of the Commodity Weather Group LLC in Bethesda, Maryland. New England and Florida will have seasonal temperatures.
“The final surge of colder weather associated with the strong March blocking appears to flush through the eastern two- thirds of the U.S. this week, making way for a new pattern to unfold by next week,” Rogers said in a note to clients.
The U.S. heating season, when natural gas demand is heaviest, ends with March. 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 change in the weather pattern is expected to push temperatures up to 5 degrees above normal along much of the East Coast from Maine to South Carolina from April 11 to 15, according to Rogers. Seasonal temperatures are expected to dominate elsewhere, except the Southwest, where warmer weather may prevail, and Montana and the upper Great Plains, which may be cooler.
The normal average temperature on April 1 in New York City is 47 degrees Fahrenheit (8 Celsius), according to MDA Weather Services in Gaithersburg, Maryland. In Boston, it’s 43; in Chicago, 44; in Houston, 67; in St. Louis, 52; and in Burbank, California, it’s 60.
