Nashville, TN – The National Weather Services has issued a heat warning for Clarksville-Montgomery County as well as parts of Middle Tennessee. Afternoon heat index values across locations generally west of the Cumberland plateau region are expected to reach between 100 to 105 degrees this weekend through Monday.
A strong upper level ridge will continue to generally be in place across Middle Tennessee through this weekend into early next week. This will continue to allow afternoon high temperatures to be in the mid to upper 90s across Middle Tennessee.Factoring in the expected moisture content of the atmosphere during these afternoon hours, commonly known as relative humidity, to the actual air temperatures, it will feel like temperatures are between 100 to 105 degrees during these afternoon hours.
It is also important to remember that exposure to full sunshine can increase the heat index value by 15 degrees.
This strong upper level ridging is expected to slowly shift westward through Monday also. This will allow for isolated to scattered showers and thunderstorms to develop across the mid state during these peak heating afternoon hours as well.
Though providing a potential quick relief from the heat, thunderstorms that do develop will potentially be strong, with brief heavy rainfall and frequent cloud to ground lightning strikes the main concerns.
There are multiple outdoor events this weekend and into early next week across the mid state. Event organizers, participants, spectators and visitors should take the proper safety precautions to protect yourself from the heat, as well as anyone being outside.
Slow down, wear light colored clothing and drink plenty of water or other non alcoholic caffeine free beverages. Eat smaller meals and eat more often. You can use a small battery based or electric fan also. Although it will not cool the air outside, fans do help evaporate sweat which cools the body.
Check on the elderly, disabled, children playing outside and the homeless. It is also very important to remember to not leave small children or pets unattended inside a vehicle for any length of time. As vehicles can warm up very quickly in a matter of just a few minutes causing life threatening conditions.
