The U.S. Northeast may have its last chance of the season today for temperatures in the 90s, said Matt Rogers, president of Commodity Weather Group LLC.
After temperatures peak in the low 90s Fahrenheit (low 30s Celsius) from Washington to Boston, the chances of the Middle Atlantic and Northeast getting that warm again start to fade, said Rogers, based in Bethesda, Maryland. Cooler weather will prevail throughout the region well into mid-September.
Above-normal temperatures in the big cities of the East can spur electricity use, sending prices in spot electricity and natural gas markets higher.
Today’s high temperature in New York City is expected to reach 91, according to the National Weather Service. The high may be 92 in Boston, 93 in Philadelphia, 95 in Baltimore and 96 in Washington, the Weather Service said.
The only thing that may bring 90-degree heat back to the Northeast is Leslie, a tropical storm in the Atlantic, Rogers said in an e-mail interview. One computer model stalls the storm “well off the East Coast next week,” and if that happens higher temperatures may slip back in.
“Otherwise, beyond that, the 90s story in the Northeast looks like history,” Rogers said.
