According to the NWS, Heat Index Values of 100 to 105 degrees are expected today throughout the region. The highest heat index values will be over southeast Missouri and southern Illinois where isolated locations may briefly reach 105.
A few showers and thunderstorms are expected today, especially near I-64, which will help keep the heat down at a few locations.
Forecasters advised the public to be watchful for those especially impacted by the heat. Young children, the elderly, persons with serious health issues and pets are especially susceptible to the heat during this time of year.
"Do not leave young children or pets in cars with closed windows...this could become a deadly situation in a short period of time," officials said. "Be sure to drink plenty of water, take frequent rest breaks in the shade or air conditioned shelter. Get out of the heat, if you are experiencing health issues."
While the Paducah weather officials are expecting showers in Kentucky, they added there is also a marginal risk north of a line from Cape Girardeau, Mo., to near Owensboro. Those storms include wind gusts and locally heavy rainfall.
There is a marginal risk of severe thunderstorms Friday afternoon and evening across much of the area. Damaging wind gusts and locally heavy rainfall will be the main hazards, according to NWS.
A few thunderstorms are possible Sunday afternoon and evening. However, severe storms are not expected during that time.
Heat index values will again reach the 100 to 105 range during Tuesday and Wednesday afternoons, mainly over southeast Missouri and adjacent areas of southern Illinois and western Kentucky.
