743 FXUS64 KOHX 141140 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 640 AM CDT Mon Jul 14 2025 ...New AVIATION... .KEY MESSAGES... Updated at 624 AM CDT Mon Jul 14 2025 - Afternoon and evening thunderstorms will continue through the week. - Although the severe weather risk is low, heavy rainfall, gusty winds, and frequent lightning will be possible. - Warming trend will take place this week as many locations will near or surpass 100F for heat indicies. && .UPDATE... Issued at 505 AM CDT Mon Jul 14 2025 Rinse and repeat. The forecast for today hasn`t budged from yesterday`s. For the most part, we have 40-50% PoPs across Middle Tennessee, mainly during the peak heating period. A surface and upper ridge of high pressure remains anchored to the immediate east of Middle Tennessee, so there has been no change in air mass characteristics. We will once again enjoy plenty of instability with sky-high Precipitable Water values, but also very little wind shear and weak mid-level lapse rates. The SPC does have a marginal risk across roughly the western half of the mid state, with damaging wind being the only threat. Otherwise, we`ll keep an eye out for any slow-moving storms that might produce high rainfall rates. Afternoon temperatures will reach the upper 80s to low 90s -- very close to seasonal values -- with heat indices topping out in the upper 90s to right around 100 degrees in a lot of places. && .SHORT TERM... (Tonight through Tuesday Night) Issued at 958 PM CDT Sun Jul 13 2025 Storms have dissipated this evening giving way to a quiet but very warm and muggy night. A few showers and storms remain well north across Kentucky and expect that to continue through the overnight hours. Some patchy dense fog will develop especially in areas that experienced heavy downpours earlier today. Monday should be a carbon copy of Sunday`s weather with another round of afternoon and evening showers and thunderstorms across the area. Impacts should be similar with gusty winds, lightning, and brief heavy rainfall. For Tuesday...coverage of storms looks to be slightly less and as somewhat of a warming trend takes shape with Highs in the low 90s expected. The Heat Index readings will also start climbing closer to that triple digit mark as well. && .LONG TERM... (Wednesday through next Monday) Issued at 958 PM CDT Sun Jul 13 2025 Wednesday through Friday look quite similar with best coverage of afternoon and evening convection remaining across the Plateau region. With that said, locations west of the Plateau will definitely feel the affects of the lack of storm and cloud coverage as Highs in the low to mid 90s and Heat Index values 100+F can be expected. By the weekend, a little more uncertainty takes shape with a bit better coverage of storms possibly on Saturday. However if that doesn`t quite materialize, it`s safe to say the lack of convection and cloud cover definitely equals hotter temps to deal with as we go through the weekend and into next week. So yeah, welcome to Peak Summer in Middle Tennessee! && .AVIATION... (12Z TAFS) Issued at 624 AM CDT Mon Jul 14 2025 A ridge of high pressure remains situated just east of Middle Tennessee, and the air mass characteristics are a carbon-copy of what we observed 24 hrs. ago. Morning fog at KCSV and KSRB has dissipated, so we`re VFR everywhere except a brief MVFR ceiling at KMQY. As before, we`ll start off with PROB30 remarks for TS/CBs during the afternoon, then upgrade to TEMPO once convection develops so that we can have greater confidence in timing. Once again, we expect radiation fog overnight at KCSV and KSRB. && .PRELIMINARY POINT TEMPS/POPS...
