SIOUX FALLS, S.D. — A destructive storm system brought up to 100 mph wind gusts to the Upper Midwest on Thursday, slamming the Dakotas, Minnesota and Nebraska, along with parts of Iowa, Kansas and Wisconsin, according to The Washington Post. National Weather Service forecasters are trying to determine whether the system was a derecho, which the agency defines as “a very long-lived and damaging thunderstorm” with wind gusts over 58 mph and a damage swath of at least 240 miles.
