Nashville, TN – Triple-digit heat will grip Middle Tennessee this weekend, with Nashville expecting a high of 97°F and heat index values peaking near 102°F Saturday afternoon. With little wind and full sun, conditions could become dangerous for those working or exercising outdoors.

According to the National Weather Service in Nashville, light south winds and high humidity will combine with soaring temperatures Saturday and Sunday, making it feel even hotter than the thermometer reads. Residents should avoid extended exposure from 1 to 5 p.m. and stay hydrated. Cooling centers will remain open throughout Davidson County, and travelers along I-40 should expect sluggish conditions due to heat-related vehicle issues.

A chance for isolated storms returns Monday afternoon, bringing a brief break in the oppressive sun but introducing new hazards, including slick roads and sudden downpours.
