- Dangerous heat is expected through the weekend with triple digit heat indices across most of Middle Tennessee.
This is resulting in major to extreme risk for heat-related illnesses.
- There may be a slight decrease in heat risk next week, but above-normal temperatures will continue with low rain chances.
SHORT TERM
(Tonight through Sunday Night) Issued at 1007 PM CDT Fri Aug 14 2026
Ridging aloft remains in control across the southeast U.S. supporting a weekend of intense heat.
Saturday and Sunday will be the hottest days of this ongoing heat wave.
Highs climb to the upper 90s to around 100-102, with heat index values around 110 during peak afternoon hours.
Overnight lows remain elevated in the mid to upper 70s with limited relief.
Skies stay mostly clear and rain chances are lower than the past few days.
Sunday continues the extreme heat as highs climb to around 100 in many locations, with similar heat index values.
The Extreme Heat Warning (west of the Plateau) and Heat Advisory (along the Plateau) remain in effect through Sunday evening.
Overnight Sunday into Monday stays warm and muggy with lows in the mid to upper 70s.
LONG TERM
(Monday through next Saturday) Issued at 1007 PM CDT Fri Aug 14 2026
A subtle shift in the upper pattern begins early next week as the ridge axis starts to drift to the SW. This should allow for some subtle cooling, beginning Monday across the northern portions of the area and expanding SW by Tuesday.
Highs will still remain in the mid 90s early week, but the humidity will be lower.
Overnight lows remain in the 70s.
Low chances of afternoon/evening showers and storms return next week, driven by afternoon instability and any weak impulses that can sneak around the ridge.
Coverage is expected to remain isolated to scattered at best.
Through the middle of the week, temperatures stay above normal under continued ridging influence, though not quite as oppressive as the weekend peak.
Daily highs mostly in the upper to mid 90s with heat indices still frequently reaching the upper 90s to low 100s.
Precipitation chances remain low, with only modest increases possible if a weak boundary or shortwave can influence the region later in the period.
Confidence decreases beyond mid next week regarding any specific timing of any more substantial pattern change.
