A significant heat wave will develop over much of the central portion of the country into next week as a large and strong subtropical high entrenches itself over the central U.S. This significant heat wave will also affect much of western and central Nebraska.  Temperatures are expected to rise well into the 90’s with some locations exceeding 100 by Tuesday.  Combined with high dew point temperatures across central and southern Nebraska, heat index values will soar above 100 degrees.
