Hot Weather May Spread From Midwest to East by Weekend

Temperatures of more than 100 degrees Fahrenheit (38 Celsius) may spread across the Midwest, including Chicago, this week before the heat drifts into the mid-Atlantic states.

Chicago may have a high of 101 degrees by June 28 and St. Louis may reach 104 the next day, according to the National Weather Service. While Tropical Storm Debby gave oil and gas producers a scare over the weekend, forcing evacuations of off- shore rigs in the Gulf of Mexico, the heat drifting east may provide the bigger boost to energy markets.

“The big story this week is not Debby, but rather a strong heat surge in the middle of the nation that travels eastward over the next several days,” Matt Rogers, president of Commodity Weather Group LLC, wrote in a note to clients today from Bethesda, Maryland.

A heat wave throughout the Northeast and into eastern Canada last week pushed up day-ahead electricity prices across the region. On June 21, day-ahead prices reached a three-year high in New York as temperatures rose into the 90s in the city.

Temperatures from Utah to Delaware may be 5 to 7 degrees above normal from June 30 to July 4, according to MDA EarthSat Weather in Gaithersburg, Maryland. New York and New Jersey may have temperatures 3 to 4 degrees higher during the same time period, the commercial forecaster said.

The high temperature in New York may reach 88 on June 29 and Washington may be 10 degrees higher, according to the Weather Service.

For July 1, the normal average temperature in New York City is 76, according to MDA. It’s 72 in Boston; 79 in Washington; 80 in Atlanta; 74 in Chicago; 84 in Houston; 64 in Seattle and 73 in Burbank, California.
