125 FXUS64 KOHX 131836 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 136 PM CDT Thu Jun 13 2024 ...New AVIATION... .SHORT TERM... (Rest of today through Friday) Issued at 1133 AM CDT Thu Jun 13 2024 We have a pretty decent day going on across Middle TN right now. Temps have climbed into the 80s for almost everyone and without a southerly boundary layer flow, some mixing is occuring. This is helping to drop dew points in a few spots and relaxing RH values. Take advantage. This isn`t going to be the case moving forward into the weekend. In the short term, look for some fog development tonight, especially near bodies of water. I don`t think we`re going to need a dense fog advisory, but just know visibilities could drop off quickly near lakes and rivers during your morning commute tomorrow. After any fog dissipates, we`re looking another decent day with afternoon highs in the low 90s, like today. Models continue to push an unseasonal front through the region during the day tomorrow, but it still looks to wash out before it can cause any rain chances here across the mid- state. The most likely result from the frontal passage is afternoon highs a degree or two cooler Saturday than we`ll see today or tomorrow. && .LONG TERM... (Friday Night through next Thursday) Issued at 1133 AM CDT Thu Jun 13 2024 By the end of the weekend, upper level ridging will re-assert itself across the eastern half of the US. This is going spike afternoon highs here in Middle TN. Chances of reaching triple digit air temperatures aren`t looking great, but highs in the upper 90s coupled with dew points in the upper 60s is likely going to push a few areas in triple digit Heat Index values on Sunday. With the ridge in place, I think rain chances will be very, very small Sunday, but as the ridge pushes east on Monday, we could see enough height falls to create a chance of isolated to scattered afternoon storms. If this occurs, these will fall into the typical summertime thunderstorm category -- heavy rainfall and gusty winds possible. Beyond Monday, rain chances fall off once again, but afternoon temperatures look to remain in the low 90s as summer heat starts to take hold across the area. && .AVIATION... (18Z TAFS) Issued at 1255 PM CDT Thu Jun 13 2024 Dry weather and high pressure will allow for VFR conditions at all sites throughout the period. Light southwest winds should go calm tonight while skies stay mostly clear. There is a chance of fog around rivers and lakes, but it may not be widespread enough to warrant mention in tafs tonight. && .PRELIMINARY POINT TEMPS/POPS...
