Area Forecast Discussion National Weather Service Nashville TN 1223 PM CDT Sat Aug 16 2025 ...New AVIATION... .KEY MESSAGES... Updated at 1221 PM CDT Sat Aug 16 2025 - Intensifying heat wave will peak Monday and Tuesday with highs in the mid to upper 90s and heat indices in the triple digits west of the Cumberland Plateau. Cooler air will move in for late week. - Little if any rain through Tuesday, then chances for scattered showers and storms increase Wednesday. && .SHORT TERM... (Rest of today through Sunday) Issued at 1145 AM CDT Sat Aug 16 2025 Steamy hot conditions will build over the next few days with a strong upper level ridge sprawling across much of the nation. Highs will reach the mid to upper 90s with heat index values topping 100 for most areas west of the Plateau. We are borderline for Heat Advisory issuance for Sunday, and based on coordination with neighbors we will hold off for now. The ridge will squash most deep convection, but a stray storm or 2 cannot be ruled out this weekend, especially over the higher terrain of the Plateau. Coverage may increase a little on Sunday based on model qpf, but coverage still likely to stay under 20 percent. No severe wx is expected. && .LONG TERM... (Sunday Night through next Saturday) Issued at 1145 AM CDT Sat Aug 16 2025 The peak of the heat wave will come Monday and Tuesday when temperatures have a good shot of exceeding 100 in some spots. Heat indices will likely push into advisory levels of 105-109 for many areas. Isolated storms may form Monday and Tuesday, but coverage will be quite limited. Looking ahead, the heat will back off slightly on Wednesday as ridging weakens over Tennessee and a strong ridge center develops out over the Four Corners region. It is possible we get some extra help with the heat from greater coverage of showers and storms. The pattern change will be felt more significantly starting Thursday as upper level winds become more northerly bringing a cold front down our way. The front will certainly not bring fall- like wx, but it will bring much welcomed relief after several very steamy days. With the frontal zone over the region late this week, scattered showers and thunderstorms should be expected each day. && .AVIATION... (18Z TAFS) Issued at 1221 PM CDT Sat Aug 16 2025 VFR conditions are expected at BNA/MQY/CKV for the forecast period. There is a medium probability of fog developing at CSV/SRB after midnight tonight. Any fog will dissipate by 13z. Winds will be 5 kts or less and variable for the next 24 hours. && .PRELIMINARY POINT TEMPS/POPS...
