High Temperatures Next Week Won’t Rival July’s Heat

A burst of hotter weather next week in the eastern U.S., the Midwest and eastern Canada won’t rival last month’s heat wave, said Matt Rogers, president of Commodity Weather Group LLC.

Temperatures are expected to be 3 to 5 degrees Fahrenheit (2 to 3 Celsius) above normal through the Midwest and into New England from Aug. 19 to Aug. 23, said Rogers, who’s based in Bethesda, Maryland. In much of Ontario and Quebec, readings may be at least 8 degrees higher than the norm.

“It still does not come anywhere near rivaling the heat in the first two-thirds of the summer as highs in the Midwest to East hold mainly in the 80s,” he said in a note to clients today. “Some moderate humidity levels should enhance the heat a bit.”

High temperatures in large U.S. and Canadian cities can increase energy demand as people seek air conditioning to cool off. During July’s heat wave, readings in the 90s and 100s came with high humidity.

The normal average temperature in New York for July 22 is 78 degrees and for Aug. 22 it’s 76, according to MDA EarthSat Weather in Gaithersburg, Maryland. The normal Aug. 22 reading for Boston is 72; in Chicago, 73; St. Louis, 79; and in Dallas it’s 84.
