Highs Monday though the greater half of the week will reach the low/mid-90s with some hitting upper-90s and possibly 100. The latest run of the GFS shows temperatures hitting low/mid-90s Monday with heat indices reaching the upper-90s/lower-100s. Zooming into Tuesday, the high for Knoxville could reach 100-102 degrees… that’s the air temperature, not the heat indices. Heat indices for Tuesday could reach 100-110.
Lows will be “cooler” in the mid/upper-70s near 80 for some.

The mountains and higher elevations will not be protected from the heat. Highs Tuesday above 3,500 FT could reach low/upper-80s – while this is lower than the valley, some don’t have air conditioning. Hiking should be held to the early morning/late evening – though lows will only be ~5-15 degrees cooler.

DO NOT LEAVE KIDS/PETS IN A HOT CAR. It only takes 10 minutes. Cracked windows are not enough. Leaving kids/pets in a car with A/C is still dangerous; what if the engine dies? Do not let your kid play in/around the car, lock your doors. Don't be the reason your child dies. pic.twitter.com/ePyWgKfGUr
