Heatwave Hits Midwest: Record-breaking Temperatures Expected

Southern Minnesota is expected to experience record-breaking heat on Tuesday and Wednesday, with temperatures reaching the mid to upper 90s and heat index values ranging from 105 to 115. Excessive heat warnings have been issued due to the combination of high temperatures and unusually humid air. In contrast, northern Minnesota will have cooler temperatures in the 60s and 70s. The wet-bulb globe temperature, which takes into account temperature, moisture, wind speed, and sun exposure, is considered a better measurement of overall stress on the body. The heatwave is expected to gradually subside by the end of the week, with temperatures dropping into the 70s statewide, but there is little rainfall in the forecast.
