277 FXUS64 KOHX 160343 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 1043 PM CDT Tue Jul 15 2025 ...New SHORT TERM, LONG TERM... .KEY MESSAGES... Updated at 1043 PM CDT Tue Jul 15 2025 - Afternoon showers and thunderstorms will continue for the period. - The risk of severe weather is low, however, heavy rainfall, gusty winds, and frequent lightning will be possible. - Heat indices each day will exceed 100 degrees each day this week for areas west of the Cumberland Plateau. && .SHORT TERM... (Tonight through Thursday Night) Issued at 1043 PM CDT Tue Jul 15 2025 Warm and muggy conditions in Middle Tennessee continue into the rest of this week. Tonight, patchy fog will once again be possible on the Cumberland Plateau, as it has been the past week or so. Wednesday, some CAMs are showing some morning showers moving west to east around 6am along and north of I-40 so we will have to watch for some early morning precipitation. With this early convection, the same CAMs are not showing much in the way of afternoon thunderstorms. However, guidance has been struggling to accurately depict the coverage (or outright existence) of diurnal showers and thunderstorms. As long as this pattern continues, diurnal showers and thunderstorms will continue to be a possibility. Heat indices on Wednesday could get up to just under heat advisory criteria, so while it is not likely at this time that one will be issued, remember to stay hydrated and stay cool if working or doing anything outside in the afternoon. && .LONG TERM... (Friday through next Wednesday) Issued at 1043 PM CDT Tue Jul 15 2025 Biggest concern the next few days is heat indices, as there are afternoons towards the end of the week when they could flirt with 110 degrees. Most likely scenario is 100 to 105 degrees, with the higher end values being more likely west of I-24. We`re actively monitoring the situation for a possible heat advisory, but at this time, just remember heat safety and recognize the signs of heat illness. Second biggest concern is with these diurnal storms, while severe weather risk is low, hazardous weather could still occur. This includes heavy rainfall rates that could lead to localized flooding, frequent lightning, and gusty winds. If you`re spending any time outdoors the next week, make sure you have a plan to keep yourself safe in case a storm surprises you while you`re outdoors. && .AVIATION... (00Z TAFS) Issued at 641 PM CDT Tue Jul 15 2025 VFR conditions to generally prevail over the next 24 hours. The lone exception is fog once again at KSRB and KCSV. Could see MVFR or IFR vis by sunrise. Outside of that, will be watching thunderstorms in NW TN as they may approach KCKV later this evening but currently anticipate weakening before arrival, just like our storms earlier. There may be some morning showers to watch for, and then our daytime convection chances tomorrow but currently have low confidence. Light winds throughout the period. && .PRELIMINARY POINT TEMPS/POPS...
