606 FXUS64 KOHX 152318 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 618 PM CDT Sun Sep 15 2024 ...New AVIATION... .SHORT TERM... (Rest of today through tonight) Issued at 1130 AM CDT Sun Sep 15 2024 The band of showers (Francine remnants) that was focused over our southwest counties the past couple of days has shifted farther southwest today as dry air has pushed in from the north and east. Still, there will be just enough moisture and instability for a few showers or brief thunderstorms this afternoon and early evening for areas along and southwest of I-24. Any storm impacts should be brief with coverage mostly in the 20 to 30 percent range. Otherwise the rest of the day will be partly to mostly sunny with warm temperatures in the 80s. Any showers or isolated storms will dissipate quickly this evening. Late night may bring some patchy fog as most areas dip to the lower 60s. && .LONG TERM... (Monday through next Sunday) Issued at 1130 AM CDT Sun Sep 15 2024 The rest of this week looks dry with pleasant nights and warm days. A strong ridge over the Great Lakes and New England will push dry and stable air into the area for the start of the week. Later in the week, another ridge from our southwest will spread across the region. This pattern will block us off from any significant wet weather systems. One of those systems will be a low pressure system along the east coast that could become a tropical low. Most models keep the impacts form this system out of our area. The GFS tracks more to the west, but the GFS is considered an outlier. Even with a western drift, odds are very low for any meaningful rainfall in our coverage area. At this point, we do have some 10-20 percent shower chances along the Plateau midweek. Otherwise, dry through the week. Clear nights and mostly sunny days will be in the forecast across Middle Tennessee this week. Dry air will allow temps to drop to comfortable levels at night with near normal lows. A few patches of shallow fog will be possible each night, mainly along lakes and rivers and in valleys. The sunny days will be warm with highs running a few degrees above normal throughout the week. && .AVIATION... (00Z TAFS) Issued at 615 PM CDT Sun Sep 15 2024 Isolated to widely scattered showers across middle TN will continue to dissipate with sunset. Don/t expect these to affect and terminals. VFR conditions expected at all TAF sites through the TAF period. SCT/BKN mid and high level clouds will also dissipate with sunset leaving a few high clouds at best. Winds will be easterly 10 kts or less and become northeasterly after 16/18Z still 10 kts or less. && .PRELIMINARY POINT TEMPS/POPS...
