182 FXUS64 KOHX 171141 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 641 AM CDT Tue Sep 17 2024 ...New AVIATION... .SHORT TERM... (Today through Wednesday) Issued at 102 AM CDT Tue Sep 17 2024 Most of the area is clear tonight with the exception being along the plateau when some mid and high clouds are working in from the east. These clouds are associated with an upper low and associated surface low centered over the Carolinas. There are a few light showers noted on KMRX in East Tennessee. Some of those scattered light showers could impact the eastern counties today as the low takes a westward jog. For the remaining two thirds of the area, the only benefits from the low will be a little more cloud cover and highs about 5 degrees cooler than Monday. The low will reach its most western point this evening before starting to move east again. This will pull the shower chances and the cloud cover back to the east as well. A light shower can`t be completely ruled out on Wednesday in the far east, but chances won`t be as high as today. For the rest of the area, expect plenty of sun with a light northerly wind. && .LONG TERM... (Wednesday Night through next Tuesday) Issued at 102 AM CDT Tue Sep 17 2024 As the upper low opens into a broader trough Wednesday night, Middle Tennessee will be on the back side of the trough with ridging building from Texas northward toward the Ozarks. That ridging will build eastward Thursday night into the weekend allowing temperatures to warm into the upper 80s to lower 90s starting Thursday and continuing through the weekend. The humidity will be tolerable with dew points in the upper 50s to lower 60s. With those dew points, expect low temperatures in the low to mid 60s. In regards to rain, chances will be very slim through early next week. && .AVIATION... (12Z TAFS) Issued at 634 AM CDT Tue Sep 17 2024 MVFR CIGs are moving into E TN and will likely impact CSV/SRB through the day today. BNA/MQY/CKV, should remain VFR through the afternoon with some high level clouds streaming overhead. Through the morning and early afternoon, light showers are possible across the Upper Cumberland. Winds will be out of the N/NNE. Tonight, IFR CIGs and VIS are likely across the Upper Cumberland including SRB/CSV. BNA and MQY could see some periods of MVFR CIGs late tonight as well, but confidence is lower with some uncertainty on how far W the lowest CIGs will push west. && .PRELIMINARY POINT TEMPS/POPS...
