Chicago May Reach 100, New York 96 as Heat Returns

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. Natural gas futures on New York Mercantile Exchange extended their longest streak of gains in more than a month on the threat of higher temperatures today after rising yesterday to settle at a five-month high of $2.767 per million British thermal units.

Heat advisories have been issued from Nebraska to Ohio and from Minnesota to Texas by the National Weather Service. St. Louis is expected to reach a high of 99 today and 108 tomorrow, according to the agency.
