LINCOLN, Neb. — An unusual, late-summer heat wave has enveloped much of the Midwest, putting schools and sports events on hold.
Schools in Iowa, Nebraska, Wisconsin, the Dakotas and Illinois let out early on Monday as temperatures crept toward the mid-90s — beyond in some places. After-school sports practices and evening games were canceled in St. Paul, Minn., and misting stations kept people cool at the Minnesota State Fair, where about 90 fairgoers had been treated for heat-related illnesses over the weekend.
The heat wave is supposed to last through much of the week, the National Weather Service said. Heat of this magnitude is unusual for this time of year, but not unprecedented. In Des Moines, Iowa, temperatures on Aug. 26 have reached 100 degrees at least six times since 1881. The weather service said South Dakota was experiencing its hottest final week of August on record.
School districts took precautions to avoid putting students and teachers in sweaty — and possibly dangerous — situations.
In central Iowa, Marshalltown Community School District administrators canceled afternoon preschool classes on Monday and Tuesday and were planning to release other students two hours early. Parts of all 10 of district buildings have air conditioning, but some rooms aren't connected.
"The buildings can heat up pretty fast, especially when you have kids in there," district spokesman Jason Staker said. "It's not a good environment for students or teachers."
Five elementary schools in Fargo, North Dakota, canceled classes through Wednesday because the buildings weren't fully air-conditioned. Temperatures inside them on Sunday ranged from 85 degrees to 90 degrees, Fargo Schools Superintendent Jeff Schatz said.
In South Dakota, the Sioux Falls School District continued with classes as scheduled, but spokeswoman DeeAnn Konrad said teachers kept window blinds closed and turned off lights in classrooms. The district was also prepared to move students into cooler rooms at nearby churches and a Christian school, she said.
