Minneapolis may reach 98 degrees Fahrenheit (37 Celsius) today and Chicago 93 as a heat wave persists across the Midwest, the National Weather Service said.
Temperatures across southern Minnesota and northern Iowa are expected to be about 15 degrees above normal through the rest of the week, according to Matt Rogers, president of Commodity Weather Group LLC in Bethesda, Maryland. Much of the Midwest and Great Plains will have readings about 8 degrees higher than the norm.
“Chicago should see upper 80s to low 90s for most of the week,” Rogers said in a note to clients.
Heat advisories have been issued for parts of Minnesota, Iowa, Illinois, Wisconsin, North Dakota, South Dakota and Nebraska, where the heat when combined with humidity may feel like 105 degrees in some places, according to the weather service. Excessive heat warnings have been issued in southern Minnesota, western Wisconsin and central Iowa.
Minneapolis reached 90 on Aug. 24 and 96 yesterday. Today’s expected high would give the city its first heat wave since July, weather service records show. A heat wave is defined as three days with temperatures of 90 or more.
A reading of 98 it would also be the highest in Minneapolis so far this year.
Hotter-than-normal weather may persist across the Midwest through September, according to MDA Weather Services in Gaithersburg, Maryland.
Temperatures are expected to be 8 degrees above normal from Montana to Illinois from Aug. 31 to Sept. 4, according to MDA. That above-normal warmth may also reach from the Canadian provinces of Saskatchewan and Manitoba to the U.S. states of Missouri and Kansas.
The forecast calls for temperatures to range from 3 to 5 degrees above normal from the Rocky Mountains to the U.S. East Coast during the same time frame, according to MDA.
Much of the Midwest and Ohio Valley are expected to have temperatures at least 3 degrees above normal from Sept. 5 to Sept. 9, MDA said. The warmest weather is expected to be in the Pacific Northwest while the East Coast will be close to seasonal.
The normal average temperature in New York City on Sept. 4 is 73 degrees, according to MDA. In Boston it’s 68; in Chicago, 69; St. Louis, 76; Houston, 83; Seattle, 64; and in Burbank, California it’s 75.
