566 FXUS64 KOHX 282324 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 524 PM CST Fri Nov 28 2025 ...New AVIATION... .KEY MESSAGES... Updated at 521 PM CST Fri Nov 28 2025 - Widespread rain showers expected Saturday night into Sunday morning, then again Monday night into Tuesday morning. Forecast total rainfall through Tuesday is 0.5"-1.5". - Low to medium chances of light snow across northwest portions of Middle Tennessee Tuesday morning. Chances for 1.0" or greater accumulation are very low (<20%) at this time. - Temperatures remain below-normal for the next several days. && .SHORT TERM... (Rest of today through Saturday) Issued at 1150 AM CST Fri Nov 28 2025 Longwave upper-troughing remains across much of the CONUS today with a shortwave disturbance evident on water vapor imagery across the Northern Rockies. This system is projected to move into the Plains tomorrow fostering a strengthening low pressure system that will move toward the Great Lakes Saturday night. A low-level jet is expected to form ahead of the advancing cold front which should support warm, moist advection and widespread light rain across Middle Tennessee into Sunday morning. Rather light rainfall amounts are forecast. We`ll also have marginal fire weather conditions Saturday afternoon due to low RH values and increasing southerly gusts prior to moistening boundary layer conditions. Until then, it`ll be another cold night tonight with lows in the 20s. && .LONG TERM... (Saturday Night through next Friday) Issued at 1150 AM CST Fri Nov 28 2025 The longwave pattern will not shift much into early next week with broad upper-troughing and passing shortwaves. In fact, a subsequent shortwave is projected to advance across the Southern Plains toward the Mississippi Valley on Monday. This appears to favor cyclogenesis close to the Gulf Coast, though southerly low- level flow is expected to spread northward into the Ohio Valley where cold/dry air is in place. Once lower tropospheric saturation occurs, wintry precipitation is possible, but is currently favoring areas north of Middle Tennessee due to warming surface temperatures within the surface trough. Nonetheless, we continue to monitor for any snowfall accumulations as there`s a low chance for accumulations across the northwest half of the area. Latest LREF probabilities show a <40% chance for seeing at least 0.1" (measurable snow), but only 10-20% chance of seeing 1.0" or more. We`re currently not expecting any meaningful accumulations or impacts for that matter. A good widespread soaking of rainfall is likely, however. The remainder of the forecast period appears cool, dry with continuation of below-normal temperatures. && .AVIATION... (00Z TAFS) Issued at 521 PM CST Fri Nov 28 2025 VFR conditions through the TAF period. Passing high clouds overnight with increasing mid-level clouds tomorrow morning and afternoon. Rain chances push in after the TAF period. Winds become southerly tonight under 5 knots. Winds pick up towards 18z becoming 6-12 knots with gusts up to 22 knots. && .PRELIMINARY POINT TEMPS/POPS...
