335 FXUS64 KOHX 040423 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 1123 PM CDT Sun Aug 3 2025 ...New SHORT TERM, LONG TERM... .KEY MESSAGES... Updated at 1118 PM CDT Sun Aug 3 2025 - Below normal temperatures will continue through mid-week. - An unsettled pattern is expected throughout the week, with low to medium rain chances each afternoon/evening. However, the severe thunderstorm threat is very low for at least the next 8 days. && .SHORT TERM... (Tonight through Wednesday Night) Issued at 1118 PM CDT Sun Aug 3 2025 Showers have come an end for today, but partly to mostly cloudy conditions persist as low-level moisture remains and an inverted surface trough hangs just off to our east. This trough, plus a developing upper level trough over the midwest will do two things for us here in Middle TN through Wednesday: 1. low to medium chances for rain with a few rumbles of thunder each afternoon/evening (with the best chances east of I-65 each day) and 2. keep temperatures well below normal for everyone. Right now, I don`t see any signal for heavy rain, like we had in Wilson county today. However, overall flow will continue to be weak, so this will need to monitored. No severe weather is expected, either. && .LONG TERM... (Thursday through next Monday) Issued at 1118 PM CDT Sun Aug 3 2025 Thursday looks to be a day of transition for us. Diurnal showers and thunderstorms will still be around, but we begin to lose the influence of the upper level troughing and (weak) high pressure starts to reassert itself across the southeast United States. I think we maintain the low to medium storm chances each day, where not everyone will see rain, but with temperatures starting to climb back into the low 90s for many, we will return to a much more unstable air mass. Those that do see storms will run the risk of seeing a few gusty winds, heavy rain and lots of lightning. This should be the case for Friday right through next weekend. Fortunately, forecast soundings for the second half of the workweek look rather benign with 6.0 deg/km lapse rates or less, so the threat of any severe weather should be very low. && .AVIATION... (00Z TAFS) Issued at 621 PM CDT Sun Aug 3 2025 An inverted surface trough situated just east of the Tennessee River has provided the focus for numerous showers and a few storms today, some exhibiting very high rainfall rates. Active weather is on the decline now and should remain at a nadir during the overnight period and during the day tomorrow. We do expect overnight low ceilings at some of the terminals and also light radiation fog -- especially along the Cumberland Plateau. All TAFs are VFR from 13Z onward. && .PRELIMINARY POINT TEMPS/POPS...
