330 FXUS64 KOHX 100534 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 1234 AM CDT Mon Aug 10 2026 ...New AVIATION... .KEY MESSAGES... Updated at 1231 AM CDT Mon Aug 10 2026 - Heat Risk will climb to Major level (3 out of 4) this week. Heat Advisories may be issued west of the Plateau, especially Tuesday and Wednesday. - Low to medium (10 to 40 percent) chance of showers and storms each afternoon and early evening (highest chances along the Cumberland Plateau). Heavy downpours with local flash flooding will be the main concern. Gusty winds can`t be ruled out, but the threat of severe winds is very low. && .SHORT TERM... (Tonight through Wednesday Night) Issued at 1041 PM CDT Sun Aug 9 2026 Sunday turned out to be our quietest day of weather in the last week. A few spots saw some thunderstorms, but after the flooding we saw Saturday in Williamson County, I`ll take the lack of activity anytime. This also provided our soils an opportunity to recover after the widespread storms on Saturday. Some patchy fog will be possible after midnight, but shouldn`t be widespread at all. We`ve been talking about this quite a bit the last few days and it does look like we`re going to start seeing more upper level ridging begin to influence our weather in Middle TN on Monday. The Bermuda Ridge has started to retrograde to the west and while a couple of storms can`t be ruled out, I think the bigger issue will start to become the heat. Now, while tomorrow should be a couple of degrees warmer than we saw today, I don`t think it`s going to be our warmest and most humid day of the week. This looks like it`s going to be Tuesday and maybe even again on Wednesday. A couple of spots may reach Heat Index values of 105 tomorrow, but by far, feels-like temps of 105 to 107 degrees will be much more widespread on minimally on Tuesday, but even Wednesday. For this reason, I`ll hold off on the heat headline for tomorrow and focus on the middle of the week for Heat Advisories. && .LONG TERM... (Thursday through next Monday) Issued at 1041 PM CDT Sun Aug 9 2026 As we reach Thursday, there are still some inconsistencies between models. However, it does seem as though stronger ridging may end up winning out over the mid-state and the latest NBM is definitely picking up on this. What was upper 80s to about 90 for the second half of the week has now become mid 90s for areas west of the Cumberland Plateau right into next weekend. NBM MaxT probs each afternoon starting Thursday through next weekend of seeing 95+ degrees stands at 70-80% for many west of the Plateau. Only 48 hours ago, it was only 30-40%. Big change. Dew points will be the big challenge, but even at these environmental temps, we may only be in advisory territory. Again, I don`t think we rule out a stray storm for the second half of the week, but if temps are going to get this warm because of a strengthening ridge, convection should be at a minimum each afternoon. && .AVIATION... (06Z TAFS) Issued at 1231 AM CDT Mon Aug 10 2026 MVFR fog is possible for CSV and SRB near sunrise this morning, but all other TAF sites should remain VFR with light southwesterly winds through the period. There`s a low to medium chance of showers and storms along the Plateau this afternoon and evening, but chances are lower than they have been over the past few days. && .PRELIMINARY POINT TEMPS/POPS...
