An Excessive Heat Warning is in effect for portions of south central Wisconsin Today. This includes the Dodgeville, Darlington, and Monroe areas. A heat advisory is in effect for areas along and south of a Baraboo, to Watertown, to Brown Deer line. This includes the Milwaukee and Madison areas. When warm temperatures combine with high humidity, conditions feel warmer than the actual air temperature. We can quantify these conditions by the Heat Index. When heat indices are expected to exceed 100 degrees, we (the National Weather Service) issue Heat Advisories or Excessive Heat Warnings, depending on the values and length of time the extreme conditions are expected to last. The last time we've had an Excessive Heat Warning issued for the area was back on July 3-7, 2012! Thus, it's been awhile since we've had the potential for heat of this magnitude.
