Cooler Air to Dominate Midwest Next Week Chilling Chicago

Temperatures are forecast to drop at least 10 degrees Fahrenheit (5.5 Celsius) below normal next week across the Midwest, including Chicago and St. Louis.

The cooler weather will spread as far south as Texas, according to Matt Rogers, president of the Commodity Weather Group LLC in Bethesda, Maryland.

“The latest estimates bring upper-40s to the upper Midwest with lows in the 50s farther south and east,” Rogers said in his report to clients. “Highs in Chicago next Tuesday may only be in the 60s, an impressive feat for middle July.”

Cooler weather than usual in the large U.S. cities in the heart of summer can decrease air conditioning use, cutting back energy demand and the need for natural gas and other fuels to generate electricity.

MDA Weather Services predicts the daily average temperature in Chicago will be 64.5 on July 16, or 10.5 degrees below normal. In St. Louis, it will be 70, or 10 below the norm, and in Minneapolis it will be 63, or 11.5 lower.

While the central U.S. cools, readings in the Pacific Northwest will remain at least 10 degrees higher than usual next week, said MDA in Gaithersburg, Maryland. Seattle’s high may reach 92 on July 16.

Temperatures could drop to about 3 degrees below normal in Pennsylvania and parts of New York next week, while seasonal weather dominates the rest of the East Coast.

For July 16, the normal average temperature in New York is 78 degrees, MDA said. It’s 74 in Chicago and Boston, 80 in St. Louis, 86 in Dallas, 66 in Seattle and 75 in Burbank, California.
