...Peak Heat Indices of 100 to 105 For Several Locations on Wednesday and Thursday... High temperatures will reach the low to mid 90s for locations below 2500 elevation on Wednesday and Thursday afternoons. Meanwhile, dewpoints in the upper 60s to lower 70s will result in heat indices peaking as high as 100 to 105 for several locations, especially deeper valley locations and areas near Lake Cumberland. Wear lightweight and loose fitting clothing. If possible, limit strenuous activities to early morning or evening. Those with outdoor activities during the afternoon to early evening should drink plenty of fluids and take frequent breaks. Stay in an air- conditioned room as much as possible, limit time in direct sunlight, and check up on relatives and neighbors.
