Area Forecast Discussion National Weather Service Nashville TN 231 PM CDT Sat Jul 8 2023 ...New SHORT TERM, LONG TERM... .SHORT TERM... (This afternoon through Sunday Night) Issued at 203 PM CDT Sat Jul 8 2023 Water vapor imagery this afternoon shows a trough tracking through our area which is aiding in the increased storm coverage through the remainder of the short-term period. Isolated to scattered activity out there this afternoon should pick up in coverage this evening and then more so Sunday as the trough's associated cold front moves through Middle TN. There is still a decent amount of instability today and tomorrow with CAPE values nearing 2,000 J/kg, but wind shear remains on the weaker side at around 20 to 25 knots. While strong thunderstorms will still be possible this evening and again on Sunday, they will likely have a hard time sustaining themselves for very long. Main threats will be damaging wind gusts with some localized nuisance flooding from heavy downpours. Storms will come to an end west to east Sunday night with drying and cooling conditions behind the cold front. As such, Sunday's high temperatures will trend down several degrees compared to today with cooler lows expected as well. Patchy fog will also be possible, particularly Sunday night, for those locations along and near the Plateau. && .LONG TERM... (Monday through next Saturday) Issued at 203 PM CDT Sat Jul 8 2023 With drier air in place to start the new week, it should be a pleasant Monday and Tuesday. Mostly dry conditions are expected both days, and while temperatures will be able to quickly rebound back into the low to mid-90's, RH values will be lower in the 30's and 40's. The weather pattern will turn active again though by Wednesday as a couple of shortwaves move through the area and moisture makes its return, keeping rain and thunderstorm chances in the forecast through at least next week. Stay tuned. && .AVIATION... (18Z TAFS) Issued at 1231 PM CDT Sat Jul 8 2023 Scattered showers and storms will become more prevalent as the afternoon progresses likely impacting the terminals. Prevailing tsra was included during the most likely time frame. Visibilities could drop as low as LIFR/IFR during the heaviest downpours. In addition, some strong wind gusts will be possible with the storms. Storm chances will end overnight, but there is a high probability that fog impacts MQY/CKV/SRB/CSV. Fog will dissipate by 09/13z, but MVFR Cu is expected to develop for the remainder of the taf period. && .PRELIMINARY POINT TEMPS/POPS...
