FXUS64 KOHX 240308 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 1008 PM CDT Sun Aug 23 2026 ...New SHORT TERM, LONG TERM... .KEY MESSAGES... Updated at 953 PM CDT Sun Aug 23 2026 - Look for dry, cooler evening and overnight periods through Tuesday morning. Fog is possible across the river valleys each morning. - Low to medium rain and storm chances return Wednesday and Wednesday night, then taper off on Thursday. But no hazardous weather is expected for the foreseeable future. - Temperatures from Wednesday through the weekend will stay close to seasonal norms, then perhaps a little warmer to start off next week. && .UPDATE... Issued at 617 PM CDT Sun Aug 23 2026 The 00Z sounding at OHX is barely underway, but already we can tell you that the temperature and dew point curves are miles apart, so that's pretty much all you need to know about the state of the atmosphere this evening. It feels wonderful outside, with the humidity at a nadir and a pleasant north breeze coming in. High pressure over the upper midwest is bringing us this cooler, less humid air mass. The next two mornings promise to be several degrees cooler than normal, and the next opportunity for active weather won't come our way until Wednesday. Although summer is far from over, you can almost hear autumn knocking at the door. && .SHORT TERM... (Tonight through Tuesday Night) Issued at 953 PM CDT Sun Aug 23 2026 Temperatures are cooling off quite nicely this evening and low dew points are allowing for excellent radiation cooling across Middle Tennessee. We've got couple of cool nights in store, along with non-existent rain chances the next couple of days. This evening, high pressure centered over the upper midwest is keeping the air mass over Middle Tennessee dry and a little cooler than seasonal norms, while we remain underneath a northwest flow aloft with ridging situated to our west. && .LONG TERM... (Wednesday through next Monday) Issued at 953 PM CDT Sun Aug 23 2026 Our next rain chances start to develop on Wednesday as a surface low comes together over the Arklatex and develops a boundary across the Gulf Coast states and into the Tennessee Valley. It's not a lot to work with, but we do introduce low to medium PoPs Wednesday and Wednesday night, with rain chances tapering off on Thursday as the system pulls off to the east. Although there will be some storm chances, QPF values are somewhat anemic, and we certainly aren't outlooked for any severe storms for the foreseeable future. Temperatures will warm up to seasonal values by Wednesday, with readings staying close to seasonal norms through the weekend, then warming up a bit to start off next week. && .AVIATION... (00Z TAFS) Issued at 612 PM CDT Sun Aug 23 2026 VFR conditions persist this taf cycle with light northerly winds. A mid-level cloud deck around 6000 ft is streaming in from the northwest and this will lead to episodes of SCT to BKN cloud coverage through the period. && .PRELIMINARY POINT TEMPS/POPS...
