051 FXUS64 KOHX 070511 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 1211 AM CDT Sun Jul 7 2024 ...New AVIATION... .UPDATE... Issued at 812 PM CDT Sat Jul 6 2024 Clouds clearing out over the Middle Tennesse area. Winds are expected to shift to a more north easterly wind direction while still remaining light. Patchy fog over Cumberland Plateau from 06Z till after sunrise is expected. No major forecast changes were made. && .SHORT TERM... (Rest of today through Sunday night) Issued at 1115 AM CDT Sat Jul 6 2024 Some high clouds continue to stream into the area at forecast time, especially over the western half. Those east of I-65 are just now starting to reach convective temperatures, which means cu fields are starting to develop. PoPs this afternoon remain at 10% or less and with the inversion at 800 mb on this morning`s OHX sounding there`s no reason to increase them, even for an extremely isolated pinhead shower or two that might develop east of I-65 today. Temperatures might be running a touch ahead of the overnight forecast, but with slightly lower dew points filtering in from the north, feels-like temps should remain below triple digits. Similar conditions are expected tomorrow with 10% or less PoPs and afternoon highs in the low to mid 90s. && .LONG TERM... (Monday through next Saturday) Issued at 1115 AM CDT Sat Jul 6 2024 Things start to change on Monday, however. Southerly boundary layer flow kicks in and icky dew points return. That means low triple digit Heat Index values will return to the mid-state. In addition, rain chances start creeping back into the forecast. With the Bermuda high back over the Atlantic, a trough approaching from the northwest and Beryl making landfall in TX Monday morning, rain chances will increase precipitously (see what I did there?) Monday night, Tuesday and right into the day on Wednesday. Current WPC guidance runs 1 to 3 inches of rainfall across the mid-state. For now, this is acceptable as ensembles show less than 10% chance of more than that, but we will need to watch this closely over the next couple of days as we figure out the path of Beryl`s remnants. After Wednesday, rain chances don`t disappear from the forecast as Middle TN remains in kind of a convergence zone between a trough to our north and the ridge to our east. This should keep a minimum 30 to 50% PoP in the forecast through the remainder of next week. With the general troughiness, though, that means we should hover near more normal temperatures for this time of the year. && .AVIATION... (06Z TAFS) Issued at 1209 AM CDT Sun Jul 7 2024 VFR conditions through the TAF period. Fog potential is overall low tonight but maybe some patchy fog in the vicinity of KSRB between 09 and 12z. Light northerly winds 6 knots or less. && .PRELIMINARY POINT TEMPS/POPS...
