An excessive heat warning stretches over most of central and southern Minnesota — and it isn’t expected to end until late Thursday. The hot weather blanketed the southern part of the state on Monday, with records being broken in numerous communities as temperatures approached 100-degrees in many locations. Mankato set a new record high with the mercury hitting 96-degrees. New Ulm saw a high temp of 95-degrees on Monday, missing the record high by 1-degree. The heat isn’t forecast to break for at least the next few days, leading public health officials to issue warnings that people should limit their time outside, stay hydrated and make sure not to leave kids or pets locked in cars.
