Once again, we will see these heat indexes reach dangerously high in the 100ºF+ range and if you are out, make sure you drink plenty of water and find some shade and don't be out in the sun constantly.
For the people N/NE of Nashville, there is actually a weak system pushing through to our north and the fringe of it will clip this part of Middle TN and SCK. With the isolated storms that do pop, isolated hail and strong wind gusts could be possible. The SPC has us just in a "See Text" area, but we could see a slight risk be issued for this area if they think the threat will be more scattered then isolated.
Nonetheless, even with these slight storm chances, we still need to take the precautions I mentioned above as not everyone will see rain today. Only a 30% chance for the storm possible areas.
