Area Forecast Discussion National Weather Service Nashville TN 617 AM CDT Sat Jul 25 2026 ...New AVIATION... .KEY MESSAGES... Updated at 609 AM CDT Sat Jul 25 2026 - Medium to high rain chances continue through this afternoon. No severe weather is expected, but there is a low flood threat. - Hot and humid conditions will resume next week with low rain and storm chances. - Heat indices in the low 100s are expected Sunday through Tuesday in many locations west of the Cumberland Plateau. && .SHORT TERM... (Tonight through Sunday Night) Issued at 1039 PM CDT Fri Jul 24 2026 A line of very light echoes is inching its way across the Cumberland Plateau while the remainder of Middle Tennessee remains echo-free. The HRRR does show some redevelopment during the overnight period, but we don't expect the overnight activity to widespread or particularly onerous. Showers and storms will become a little more active tomorrow as an upper trough pushes across the region, but the risk of severe storms remains very low. There is a marginal risk of excessive rainfall, but this would only occur in isolated spots impacted by heavier cells. Overall, this appears to be a low-impact event, with most areas looking QPFs of 1/4" or less throughout this event. Meanwhile, Precipitable Water values continue to climb, having reached 1.68" on the evening sounding from OHX, but still a far cry from the 2+ inches we were seeing earlier in the week. Once this oncoming active weather system exits the region Saturday night, look for temperatures to warm up quickly. By Sunday afternoon, we can expect heat indices in the low 100s many areas west of the Cumberland Plateau. && .LONG TERM... (Monday through next Saturday) Issued at 1039 PM CDT Fri Jul 24 2026 Tuesday will likely be our warmest day, as afternoon temperatures reach the mid to upper 90s and heat indices peak at 105+ in many areas. Thus, it is quite possible that a Heat Advisory will be needed for Tuesday, and Tuesday only. At this time, the atmospheric models are bringing a surface boundary through the mid state late Tuesday that would bringing nominally cooler temperatures, and also lower humidity. It also appears that the fropa would be a dry one except for a spotty shower or two. In fact, after Saturday night, our rain and storm chances for the remainder of the 7-day forecast period look to be negligible. && .AVIATION... (12Z TAFS) Issued at 609 AM CDT Sat Jul 25 2026 Showers are moving through Middle TN early this morning where they are producing MVFR visibilities is some spots. Shower activity will linger through the morning, and then there is a low chance for afternoon thunderstorms to impact the terminals. PROB30 groups have been maintained for this. Once activity diminishes late this evening, fog looks to develop tonight after 06Z. Highest confidence in dense fog is across the Plateau, including at SRB and CSV, but all terminals will have to be watched closely due to today's rain and light overnight winds. && .PRELIMINARY POINT TEMPS/POPS...
