Historic heat wave to bake the Heartland - KFVS12 News & Weather Cape Girardeau, Carbondale, Poplar Bluff

Historic heat wave to bake the Heartland

(KFVS) -

Heat advisories, warnings and a Red Flag (fire) Warning are in effect for the next few days.

A heat wave pattern that has been breaking records across the plains this week is now expanding east into the Mississippi Valley. High pressure aloft will combine with full sunshine and southwesterly breezes to push air temperatures well above 100° for the next few afternoons. In fact, for most of us these will likely be the highest temperatures we've ever experienced.

Part of the reason for the extreme heat is the ongoing drought, as very dry conditions mean that more of the sun's energy is converted into heat. Thankfully this also means that humidity levels will be rather moderate for our region, and the heat index will be close to if not slightly below the actual air temperature for at least the next day or two. By the weekend, however, humidity levels as well as heat index numbers may begin to climb even as actual air temperatures begin to decrease slightly.

Cape Girardeau historical data for the next few days:

  • Record high for June 28: 103° (1952).
  • Record high for June 29: 103° (1969).
  • Record high for June 30: 102° (1969).

All-time record high (highest temperature ever recorded): 107° on July 28, 1952.
