367 FXUS61 KRNK 111522 AFDRNK Area Forecast Discussion National Weather Service Blacksburg VA 1022 AM EST Thu Dec 11 2025 .SYNOPSIS... Mountain snow showers will taper to flurries for the afternoon as high pressure builds across the forecast area. Winds will also diminish with time. Another weather system will cross the area Friday to produce more snow across West Virginia and western Virginia. An Arctic cold front will cross the area Sunday to bring a few days of bitter cold for the beginning of next week. && .NEAR TERM /THROUGH TONIGHT/... As of 1015 AM EST Thursday... Key Messages: 1) Lingering flurries expected across the mountains through this afternoon. 2) Winds diminishing. 3) Light snow from the next disturbance arrives late tonight. Ongoing snow showers across the mountains are expected to fade to just flurries as winds diminish. Clouds have faded east of the Blue Ridge with mostly sunny conditions expected across the eastern CWA this afternoon. Clouds will linger in the west with not much sun expected west of the Blue Ridge today. As a result of cloud cover and continued cold air advection, highs likely to remain at or below freezing today for the mountains. Farther east, should see temperatures creep into the low to mid 40s. Weak high pressure will build over the region tonight ahead of an advancing clipper system moving southeast out of the northern Plains. Should see lows fall in the mid to low 20s. Some light snow may approach the western mountains after midnight tonight, but it will remain light. The bulk of the snow from this clipper system will fall during the day on Friday. Will be taking a close look at the 12Z models and issue winter weather advisories where snow will be most impactful Friday. Similar to the last couple of snow events, this one should start prior to daybreak will potential impacts to the morning commute Friday. && .SHORT TERM /FRIDAY THROUGH SUNDAY NIGHT/... As of 225 AM EST Thursday... Key Messages: 1) A clipper system will provide snow showers on Friday for parts of West Virginia and Virginia. 2) Another clipper system should bring mountain snow showers and gusty northwest winds during Saturday night into Sunday. 3) By Sunday and Sunday night, an Arctic air mass will bring dangerously cold conditions. With the eastern United States embedded in a deep upper level trough from the northern stream, a relentlessly active weather pattern should continue for the next couple days. A weak shortwave trough spiraling around the parent trough should pass overhead on Friday. This energy will bring a clipper system that should produce snow showers for most of West Virginia and Virginia. The highest snowfall totals are expected across western Greenbrier County where three to five inches are possible, but minor accumulations up to an inch may spread through parts of the Virginia Piedmont. While snow showers should reach the northwest North Carolina mountains, it may become a mix of rain and snow in the North Carolina Piedmont. After the snow showers fade on Friday night, a lull in activity should take place during Saturday morning before the next upper level low and its associated clipper system enter by Saturday night. This clipper system appears more potent in terms of dynamic strength and will drag an Arctic cold front eastward. While another round of snow showers seems possible on Sunday for the same locations compared to Friday, the real impact should come after the passage of this Arctic cold front. Blustery conditions will occur due to gusty northwest winds and a punch of sharply colder air. The winds may gradually subside later on Sunday night as Canadian high pressure approaches. Dangerously cold conditions appear likely during Sunday and Sunday night as temperatures plummet throughout the day and into the overnight hours. Low temperatures on Sunday night could dive into the single digits along and west of the Blue Ridge, while the Piedmont may experience lows in the lower to mid teens. For context, these readings stand roughly five degrees above record low territory for this time of year. The Arctic air mass combined with the wind will result in wind chill values dropping below zero in the mountains and the single digits east of the Blue Ridge. The highest elevations might even witness wind chills temporarily falling below -20 degrees. Make sure to bundle up with several layers during this time. && .LONG TERM /MONDAY THROUGH WEDNESDAY/... As of 225 AM EST Thursday... Key Messages: 1) After a frigid Monday, milder air should help to moderate temperatures by the middle of the week. 2) Dry weather will persist for most of this forecast period as the next chance of precipitation arrives late Wednesday. Canadian high pressure should settle across the Appalachian Mountains on Monday to end the recent stretch of active weather. The synoptic pattern will change significantly as the deep upper level trough departs offshore. Ridging should occur aloft during Monday night into Tuesday, and the upper level flow should become mainly zonal by Wednesday. Meanwhile, the surface wind will turn to the southwest and increase warm air advection. Adding up these atmospheric changes yields a dry forecast with a moderating trend taking place. High temperatures could possibly return towards the lower 40s to the lower 50s by the middle of the week. The models indicate that a low pressure system may approach the Ohio River Valley by late Wednesday to provide increasing clouds. It appears that the next chance of precipitation could reach southeast West Virginia just after sunset on Wednesday evening. && .AVIATION /15Z THURSDAY THROUGH MONDAY/... As of 630 AM EST Wednesday... General consensus through this morning over the mountains will be MVFR, to brief periods of IFR, as bands of snow showers continue, along with persistent upslope stratus. Further east of the mountains ...for ROA/LYH/DAN continued VFR expected through the period. MVFR/IFR from TNB/BCB/BLF/LWB should continue through at least noon today, but leaning towards mostly MVFR as snow showers begin to lessen through the day. BCB should return to VFR by late morning, but MVFR stratus likely to continue for BLF and possibly LWB through tonight. Another system will approach from the NW late tonight and into early Friday. -SN will develop and could impact BCB/BLF/LWB towards the latter portions of the current TAF period. As a result, IFR potential will increase early Friday. Not anticipating any snow reaching beyond the mountains until later in the day on Friday. Northwest winds remain very gusty this morning, but will lessen as the day progresses. Gusts in the 30kt range will remain likely. Lighter winds this evening/tonight as weak high pressure builds over the region. .EXTENDED AVIATON OUTLOOK... Sub-VFR to continue into Friday night. Confidence beyond Friday is low on cigs/vsbys/wx. High confidence for a period of bitter cold Sunday night through Tuesday with potential for single digit temperatures and gusty winds. && .RNK WATCHES/WARNINGS/ADVISORIES... VA...None. NC...None.
