Temperatures in Chicago and Washington are expected to break 100 degrees Fahrenheit (38 Celsius) in the next five days while New York City may reach 96 and Newark, New Jersey, 99, according to forecasters.
Heat spreading from the Midwest to the East Coast may send temperatures to an average of 5 degrees above normal from Utah to Massachusetts, with parts of the central U.S. and southern Ontario reaching 8 degrees above normal, until July 1, said Matt Rogers, president of Commodity Weather Group LLC.
The puddle of heat will expand and contract over the area through at least July 11, boosting demand for electricity as the large cities of the East and Midwest start to bake, Rogers said.
“The coverage and intensity of hot weather for the first half of July continues to look very impressive this morning and the latest outlook adds even more demand,” Rogers said in a note to clients.
Power plants account for 36 percent of U.S. natural gas demand.
