NASHVILLE, Tenn. (WKRN) — A Heat Advisory is in effect across Middle Tennessee and Southern Kentucky until 7 p.m. Monday. Heat Index ("feels like") values in the region could be as high as 106.

It should be noted that counties outside of the Heat Advisory will also experience heat index values of 100 and above.

Through the day, feels like temperatures will be in the upper 80s and lower 90s by 9 a.m., and by 1 p.m. some spots will feel like the triple digits. Tomorrow afternoon it will feel even hotter by 4 p.m. with most of the Mid-State feeling like 100+.

The reason the area is getting so hot is due to an upper-level high-pressure system building over the area and staying around for the next week. A high-pressure system aloft is generally associated with clear skies and sinking air, and since it is so close to the Gulf, it's also going to pull in humid air from the south.

This results in a "heat dome" that traps the hot air in our area. However, when you factor in humidity, the heat indices will climb to 100+ through next week. This means the serious heat will persist into next week, getting a little hotter each day.

This could be a dangerous situation, so be sure to take your heat precautions. Drink plenty of water, take breaks in the air conditioning, and wear light, loose-fitting clothes. Be sure to check in on the elderly, kids and pets too!

A few isolated storms are possible each afternoon and evening. Not everyone will see rain, but if you do, heavy downpours and gusty winds are possible.
