809 FXUS64 KOHX 020152 AFDOHX Area Forecast Discussion National Weather Service Nashville TN 752 PM CST Mon Dec 1 2025 ...New UPDATE... .KEY MESSAGES... Updated at 752 PM CST Mon Dec 1 2025 - Low to medium chances for a light accumulation of freezing rain, sleet, and snow for northwest portions of Middle Tennessee tonight into tomorrow morning. A Winter Weather Advisory is in effect. - Dry weather expected Tuesday night through Thursday with decreasing chances for rain Friday and Saturday. - Temperatures remain below seasonal norms for the next several days. && .UPDATE... Issued at 752 PM CST Mon Dec 1 2025 We were getting reports of sleet earlier, but it seems that has transitioned into all rain for now. Into tomorrow, we should see that switch back to wintry precipitation as it exits to the east. Forecast remains on track! && .SHORT TERM... (Rest of today through Tuesday) Issued at 1200 PM CST Mon Dec 1 2025 There`s a nice plume of west-southwesterly flow aloft overspreading the eastern CONUS ahead of a shortwave trough moving east across the Plains currently. High pressure to our northeast continues to foster a dry, cold day across Middle Tennessee with light NE winds. Upper/mid-level clouds will continue to thicken through the afternoon with isentropic ascent increasing from the southwest as the disturbance approaches. By late afternoon/evening, chances for light rain increase once the lower atmosphere saturates. In fact, rain is already now approaching far southwest Tennessee (near Memphis). Rain will become widespread tonight with a quick increase in the low-level jet and northward expansion of the inverted surface trough. Surface temperatures will remain above freezing through much of the evening. However, cooler air will begin to advect into the northwest after 9 PM, and certainly after Midnight. This will support a wintry mix of precipitation for areas generally west of I-65 and north of I-40. HREF probabilities for a light accumulation of ice/sleet/wet snow have increased to 20-50% for these areas. With possible impacts to travel for the Tuesday morning commute, a Winter Weather Advisory has been issued which runs 9 PM tonight through 8 AM Tuesday. Once the back side of the surface low/trough moves east, dry air will move in from the west ending precipitation, though lingering light snow/flurries are possible during the afternoon, especially across the Plateau. Most of Middle TN will likely see a brief period of wintry precip but our focus for meaningful accumulations/impacts are focused on the advisory area. && .LONG TERM... (Tuesday Night through next Monday) Issued at 1200 PM CST Mon Dec 1 2025 Mid-week looks to be cold and dry across the region due to influence of high pressure at the surface, though low aloft appears to maintain a zonal split flow configuration. A subsequent disturbance aloft looks to enter the area late week, but guidance has trended colder, drier for this period. PoPs have decreased from previous forecasts but still remain low. We do not expect wintry precipitation at this time. Temperatures continue to favor below-normal through the period. && .AVIATION... (00Z TAFS) Issued at 520 PM CST Mon Dec 1 2025 Messy and complicated aviation forecast is upcoming. Rain is moving into the area from the west, but once temperatures fall tonight, wintry precipitation is expected. Precipitation is expected to be a mixture of rain, sleet, and snow. Highest confidence in wintry precipitation is at CKV, BNA, and MQY where TEMPO groups are in the TAFs. Precipitation will end between 11Z and 14Z from west to east, and then winds will become northwesterly behind a cold front. Cigs will also drop overnight with the precipitation, resulting in widespread IFR conditions tonight. Conditions will gradually improve after 12Z, but MVFR conditions will likely persist through the end of the TAF period. && .PRELIMINARY POINT TEMPS/POPS...
