May 21 (Bloomberg) -- The U.S. Northeast, Midwest and Rocky Mountains region may be warmer than normal from June into August, while the Southeast and West Coast are cooler, according to Weather Services International.
Arizona and New Mexico, as well as the central and northern Great Plains, may be the warmest areas in the U.S. during the period, said WSI, based in Andover, Massachusetts.
“The big story for the summer, however, is the expected reversal of the summer pattern from recent years that favored very hot temperatures across the south-central and southeastern U.S.,” said WSI Chief Meteorologist Todd Crawford.
Forecasts of hot weather in high-population areas can translate into increases in electric use as people turn to air conditioners to cool businesses and homes. The low price of natural gas has meant more power plants are using the fuel to produce electricity.
Texas may be spared another record hot summer, according to WSI.
Last year, Texas had an average temperature of 86.8 degrees from June through August, the highest for any state, according to the National Oceanic and Atmospheric Administration. The Electric Reliability Council of Texas Inc., which represents 85 percent of the state’s electric load, called for conservation measures last year because of the heat.
“We are predicting that the year-over-year change in the summer temperatures will be particularly noticeable in the Texas-based ERCOT power region, which suffered through a brutally hot and dry summer last year,” Crawford said.
Heat in the Northeast and Midwest may break in August if an El Nino develops in the central Pacific Ocean. El Nino is a warming of sea surface temperatures that affects weather patterns across the U.S.
WSI predicts most of the eastern U.S. will be cooler than normal during August.
