Heat Index Soars Over 100 Degrees in Knoxville

Knoxville is currently experiencing blistering heat as the heat index reaches over 100 degrees. In spite of the actual forecasted high being 94 degrees, it feels hotter due to high index values.

How Long Will The Heat Last?

The National Weather Service Morristown’s hazardous outlook predicts Heat index values of 100-105 in the southern and central Tennessee Valley. However, residents of Knoxville can expect a brief respite as more seasonable mid-July temperatures, with highs in the upper 80s, are forecasted. Meteorologist also adds that we can even expect a “nice breeze” as the remnants of Hurricane Beryl pass by to our north.

The breather will not last long as drier air could cause heat indexes to soar towards 100 degrees again. With most of the country, the Climate Prediction Center forecasts above average temperatures in East Tennessee through early August.

Is Summer Usually This Hot in Knoxville?

Although temperatures have been slightly above normal in recent weeks, they’re in line with previous summer seasons. The last time summer heat records were set was in 2012 when an actual heat wave caused temperatures to reach between 101-105 degrees in Knoxville.

Advice for Staying Safe in Sweltering Conditions

While no official heat advisories or warnings have been issued for East Tennessee, it is crucial to remember and practice heat safety during periods of high heat. The National Weather Service emphasizes the importance of drinking plenty of water or nonalcoholic drinks, and wearing loose-fitting, light-colored clothing.

Avoid staying out in the sun for too long, and remember to take breaks in air-conditioned areas or in the shade. Importantly, never leave people or pets alone in a closed vehicle.
