922 FXUS64 KOHX 031658 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 1158 AM CDT Sun Aug 3 2025 ...New AVIATION... .KEY MESSAGES... Updated at 1144 AM CDT Sun Aug 3 2025 - Below normal temperatures will continue this week. - An unsettled pattern is expected through midweek before lower rain chances late in the week. - The severe thunderstorm threat is very low for at least the next 8 days. && .SHORT TERM... (Rest of today through Monday) Issued at 1115 AM CDT Sun Aug 3 2025 A surface trough has drifted westward into the eastern third of our area. Scattered showers have been ongoing across the eastern half this morning. Scattered showers will continue through the afternoon before becoming less numerous after dark. Instability is weak so thunder chances will be low but not zero. CAMs have been showing the potential for some training through the afternoon but PWAT values are marginal for this time of year. With that said, there is a low chance (25%) some areas along and east of I-65 pick up an inch to two inches of rain through the evening hours. The HREF shows there is about a 10% chance that a couple localized areas exceed 2 inches. With the clouds and ongoing showers, locations along and east of I-65 will struggle to get out of the 70s this afternoon. The surface trough will drift westward into West Tennessee tonight and into Monday. A upper trough axis will approach the area Monday afternoon. Models show mainly diurnal activity on Monday with temperatures slightly warmer in the upper 70s to lower 80s but still well below normals for this time of year. && .LONG TERM... (Monday Night through next Sunday) Issued at 1115 AM CDT Sun Aug 3 2025 The upper trough will be slow to move with the axis still in West Tennessee by Tuesday afternoon. This will keep the medium shower and storm chances in the forecast and keep the below normal temperatures going. As we move through midweek, the trough will slowly weaken and broaden. Temperatures will begin to warm into the upper 80s by Thursday and Friday and rain chances will decrease. It looks like some temperatures in the 90s will join us again next weekend. && .AVIATION... (18Z TAFS) Issued at 1144 AM CDT Sun Aug 3 2025 MVFR CIGs continue at all TAFs sites. CIGs will lift and become VFR by 00Z. There is a good chance/60% chance/ of TAF sites on the Plateau KCSV and KSRB and KCKV going back to MVFR towards sunrise. Scattered showers will be present across middle TN especially for locations along I-40 and eastward. There could be heavier showers and thunderstorms. Since these will be scattered in nature will cover with SHRA and VCTS and amend TAFs as needed. Winds will be N/NE and then swinging more SE by tomorrow. && .PRELIMINARY POINT TEMPS/POPS...
