375 FXUS64 KOHX 191511 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 911 AM CST Wed Nov 19 2025 ...New UPDATE... .KEY MESSAGES... Updated at 907 AM CST Wed Nov 19 2025 - Medium (40-60%) chance for showers and a few thunderstorms overnight, tapering off early Wednesday morning. - High chances (60-100%) for rain and thunderstorms Thursday through Friday night. - Above-normal temperatures continuing, possibly turning much colder around Thanksgiving. && .UPDATE... Issued at 907 AM CST Wed Nov 19 2025 A surface boundary is in the process of inching its way southward through Middle Tennessee, with winds starting to turn northerly at some of our stations. Rain chances today are minuscule, despite the surface boundary. Temperatures will warm up quite nicely by the afternoon, especially those areas south of I-40 that will be exposed to the pre-frontal environment the longest. Look for areas of fog to develop again tonight. && .SHORT TERM... (Tonight through Thursday Night) Issued at 1035 PM CST Tue Nov 18 2025 A shortwave and weak low pressure system moving across the region will bring scattered showers and a few storms overnight. A couple of severe storms with large hail occurred northwest of our area Tuesday evening, but stable boundary layer air will keep any storms well-behaved in our area overnight. Other than some early morning straggling showers on the Plateau, Wednesday should be rain-free with clouds slowly decreasing from west to east under building high pressure. This system did not bring a cold front passage, so temperatures will remain mild with highs 10 to 15 degrees above normal. Wednesday night will be mild with above normal humidity for this time of year. Light winds and partial clearing will allow areas of fog to form. The next system, bigger and stronger, will come ot of the southwest states with at least a couple of big waves of deep moisture. the first big wave will develop Thursday morning with widespread rainy conditions by Thursday afternoon lasting into the evening. There may be some breaks in the rain late Thursday night before the next wave. Temperatures will stay mild with deep southwest flow ahead of the low pressure system. && .LONG TERM... (Friday through next Wednesday) Issued at 1035 PM CST Tue Nov 18 2025 More rain is expected Friday through Friday evening. Mild conditions will continue with strengthening southwest winds. There may be enough instability coming up from our southwest by late Friday for a few strong storms with enhanced gusty winds, but that energy could instead enhance rainfall rates. This will depend on the track of the surface low. We will have to wait and see. The rain should taper down late Friday night through Saturday morning. By the time rain ends, 48 hour totals between 1 and 2 inches will be common. The wx will settle down for Sunday into Monday, but the next southwestern system will be on approach with more rain and storms for Tuesday and Wednesday. Models are suggesting a pattern change around Thanksgiving with potential for an Arctic cold front to end our mild pattern. && .AVIATION... (12Z TAFS) Issued at 523 AM CST Wed Nov 19 2025 A stratus deck has settled into the area with all taf sites expected to be MVFR/IFR through the morning. The stratus will dissipate around 18z with VFR conditions returning. The clouds are expected to hold on until 20-21z at CSV. There will be ample low level moisture in the area overnight with the models hinting at the possibility of low clouds and fog after 06z. Confidence is highest at CSV/SRB so fog was mentioned in the tafs. Winds will be WNW to N around 5 kts. && .PRELIMINARY POINT TEMPS/POPS...
