Excessive heat index values on Sunday for Rutherford County and Middle Tennessee...

A combination of temperatures in the middle 90s and dew points in the upper 60s and low 70s will drive heat index values into the low 100s Sunday afternoon. In Rutherford County and Davidson County, the heat index could reach 110 degrees by the early afternoon. Please take the necessary precautions to protect yourself if you need to be outside Sunday afternoon. Make sure you have plenty of water to stay properly hydrated. It is also a good idea to check on the elderly and those who may not have a properly working air conditioner. 

Each year...a number of fatalities occur nationwide due to children accidentally being left in vehicles during hot or even warm weather. Never leave children or pets unattended in a vehicle...not even for a minute. Remember...beat the heat...check the backseat.
