913 FXUS64 KOHX 041736 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 1136 AM CST Thu Dec 4 2025 ...New AVIATION... .KEY MESSAGES... Updated at 1123 AM CST Thu Dec 4 2025 - A Winter Weather Advisory is in effect for portions of the Cumberland Plateau tonight for ice accumulation up to 0.10". - Mixed wintry precipitation is likely across all of Middle TN this evening from roughly 6PM-2AM. Some slick spots may develop tonight. Be cautious when travelling anywhere in the mid state. - Temperatures warm above freezing Friday afternoon. && .SHORT TERM... (Tonight through Friday Night) Issued at 1056 PM CST Wed Dec 3 2025 An active 24 to 36 hours is ahead of us as a system stemming from the gulf brings a variety of precip types to Middle TN. There was some concern earlier for a brief bout of wintry precip before sunrise, but profiles don`t look like they`ll be saturated enough for that to occur. For the main system, CAMs have almost unanimously brought the onset of precip earlier over Middle TN tomorrow. Here`s the deal: freezing air from the north will collide with this incoming rain, likely resulting in a mixed bag of winter precip types as the system moves east-northeast and surface temps hover right around freezing. What will initially start as a cool rain as it enters southwest middle TN around 6PM will eventually transition to a mix. IMPACTS: Ice- The area of greatest concern for ice impacts is along the Cumberland Plateau. There is currently a 60% chance of 0.10" of ice accumulation over portions of the plateau. Elsewhere in Middle TN, with there being varied types of precip possible with below-freezing temperatures, slick spots may develop Thursday night/Friday morning, especially over bridges, overpasses, and any sheltered roads. With surface temperatures hovering right around the freezing mark, soundings favor episodes of both sleet and freezing rain along and south of I-40. Snow- Accumulating snowfall probabilities are low overall, with a 30-40% chance of a half-inch falling over portions of northwest middle TN. The HREF paints a large swath of a medium 40-50% chance of a tenth of an inch of snow over the northern half of middle TN. Precip will come to an end by early Friday morning and temperatures will make a run at 40-45 degrees by the afternoon. That`s good news if any impacts are felt as that will help melt things off. The whole area will drop near or below freezing again Friday night, but much warmer temperatures on the order of 5 to 10 degrees warmer are in store Saturday with highs in the upper 40s to low 50s. && .LONG TERM... (Saturday through next Thursday) Issued at 1056 PM CST Wed Dec 3 2025 Saturday will be dry and cloudy as our next system approaches by Sunday. Widespread low rain chances will return with rain chances between 20-30% Sunday evening. Another invasion of cold air will be left in the wake of this system`s exit Monday, and as rain moves off to the east, lingering wraparound moisture could squeeze out a few snowflakes across the plateau Monday morning. Chances of that right now are very low, but will be something to monitor. We will dry out and enjoy a slight warming trend for the first half of next week as temperatures return back to near normal values by Wednesday (mid 50s). Our next system is slated to move through next Thursday. && .AVIATION... (18Z TAFS) Issued at 1123 AM CST Thu Dec 4 2025 Light rain will push in from the west after 22z with rain, snow, and freezing rain mixing in along and north of I-40 and over the Plateau. Precipitation will exit from west to east 7z to 11z. Light snow accumulation of less than 0.50" will be possible along and north of I-40 with light ice accumulation of up to 0.05" mainly over the Plateau. MVFR cigs build in from west to east later this afternoon into the evening with them continuing to lower to IFR/LIFR after 02z. Cigs will slowly come rise during the morning after 16z. Light northerly winds under 8 knots. && .PRELIMINARY POINT TEMPS/POPS...
