623 FXUS61 KRNK 080904 AFDRNK Area Forecast Discussion National Weather Service Blacksburg VA 404 AM EST Sat Nov 8 2025 .SYNOPSIS... A weak disturbance will bring additional light rain showers late tonight, mainly to the Piedmont, ahead of a strong cold front that will pass across the lower Mid-Atlantic on Sunday afternoon and evening. Unseasonably cold air will settle across the region from early Monday into Wednesday, supporting rounds of mountain snow showers, before the deep low pressure system supplying the cold air moves away. Temperatures will moderate closer to normal for the second half of the coming week. && .NEAR TERM /THROUGH TONIGHT/... As of 230 AM EST Saturday... Key Message: 1) Expect a mixture of clouds and sunshine today with light westerly winds and highs 5 to 7 degrees above normal. 2) A weak disturbance will bring light & spotty rain showers to the Piedmont late tonight. Radar indicates that rain is exiting the area quickly to the east this morning as a weak cold front passes across the lower Mid-Atlantic. Clouds will decrease through late morning as somewhat drier air works its way across the region, making for a mixture of passing high clouds and sunshine through the day. Despite the passage of this morning`s cold front, there is really no cold air associated with this system, and the westerly downslope winds today will support afternoon high temperatures that are 5-7 degrees above normal, ranging from the low 60s across southeast West Virginia to the low 70s across the Virginia Southside. Expect one more mild night as another weak disturbance crosses the region, bringing light and spotty rain showers across the Piedmont, with amounts generally a tenth of an inch or less. Increased cloud cover, and winds shifting from the south ahead of an approaching strong cold front will hold overnight lows in the upper 40s to the low 50s. && .SHORT TERM /SUNDAY THROUGH TUESDAY/... As of 200 AM EST Saturday... Key Messages: 1) Rain Sunday afternoon west of Blue Ridge changes to snow showers overnight. 2) Coldest air of the season so far moves into the area by Monday. 3) Flurries possible along/west of Blue Ridge Monday night. Sunday will be a transition day across the forecast area as a cold front will move through midday, with a low pressure system in the Ohio Valley tracking into the Northeastern US. Areas west of the Blue Ridge will see showers throughout the day, with more isolated showers possible for the eastern Piedmont. Behind the front Sunday evening into the overnight hours, northwesterly flow will increase. This upslope flow for the western slopes, in association with a deep upper-level trough will cause rain showers to initially occur late Sunday, with a transition to snow showers overnight as CAA occurs. Although snow showers will continue through the overnight, little accumulation is expected as ground temperatures will lag behind initially above freezing. Moisture will be the biggest question mark as to how much snow occurs and where, but the highest elevations could see a light dusting to around half of an inch by Monday morning on elevated surfaces in the NC/VA/WV mountains. A few flurries cannot be ruled out anywhere west of the Blue Ridge. Colder air then continues to pour into the area as an upper low remains overhead on Monday, and a strong surface high drives in colder air from Canada. Upslope snow showers will continue through the day, though they will remain light. Limited moisture will be supplied from the Great Lakes, with the upper low also supplying some moisture. The deep upper-level trough strengthens and pushes further south Monday night, all the way to Florida, with the trough axis moving through our area and providing enhanced lift for another burst of upslope snow showers, this time mainly for the WV mountains. With much colder temperatures in place, accumulations will be more likely, with a trace to a few tenths possible in the NC/VA mountains, with 1" to locally 3"+ possible in Western Greenbrier County. Lingering snow showers taper off Tuesday morning as high pressure builds in from the southwest and the upper-trough moves off to the east. Temperatures will be varied, as Sunday will be quite mild. Highs in the 50s for the mountains, with 60s to low 70s for the Piedmont ahead of the front. Monday and Tuesday will see winter- like temperatures as the coldest air of the season thus far moves in, with highs only in the 20s/30s along/west of the Blue Ridge, and 40s for the Piedmont both days. Overnight lows will also be cold, in the 20s/30s Monday morning and down into the teens/20s Tuesday morning. The cold will be compounded by strong NW winds of 10-20 mph and gusts of 20-30 mph Sunday night into Monday. Wind chills Monday morning will be in the teens west of the Blue Ridge, with single digits in the highest elevations. Tuesday morning will have even colder wind chill values, as wind gusts increase to 25-40 mph west of the Blue Ridge, causing wind chills to fall into the teens and single digits west of the Blue Ridge. The highest elevations will see wind chills right around zero. && .LONG TERM /TUESDAY NIGHT THROUGH FRIDAY/... As of 200 AM EST Saturday... Key Messages: 1) Quiet and dry weather expected through the period. 2) Temperatures warm quickly back to near to slightly above normal. High pressure both at the surface and aloft will build into the area Tuesday night, with quiet conditions remaining in place. Winds shift back to the southwest overnight, which will allow warmer air to advect back into the area for mid to late week. With a strong high over the Southeastern US, and waves of low pressure passing to the north over the Great Lakes Region, this will keep west to southwesterly winds elevated Wednesday and Thursday. Winds of 10-20 mph will be possible along/west of the Blue Ridge, with gusts of 25- 35+ mph expected at times. A shortwave trough and mainly-dry cold front will move through Thursday morning, but with drier air aloft, only a stray upslope shower may be possible in the WV mountains. Otherwise, dry conditions continue through the rest of the period as high pressure moves in from the west and dominates the area into the weekend. High temperatures quickly rebound on Wednesday, with 50s/60s expected, though the highest elevations may remain in the upper 40s. This stays consistent for the rest of the period. Overnight lows will start out chilly Wednesday morning, in the 20s/30s, before slowly moderating into the 30s/40s through the end of the week. && .AVIATION /09Z SATURDAY THROUGH WEDNESDAY/... As of 115 AM EST Saturday... A line of light to moderate rain continues to advance east this morning across the lower Mid-Atlantic as a weak cold front passes across the region, resulting in occasional reductions in visibility into the 3SM to 5SM range. Ceilings are currently VFR, though bases across the mountains continue to lower toward MVFR levels. Winds are light and generally from the west. Rain is forecast to exit the service area to the east by 11Z. MVFR/IFR ceilings which develop across the mountains overnight will lift quickly during the 11Z to 14Z timeframe, making for VFR conditions until the end of the 08/06Z TAF period, when a disturbance will bring showers and lowering ceilings from the Blue Ridge eastward by 09/05Z. Winds will be from the west-southwest at less than 10kts through the period. .EXTENDED AVIATION OUTLOOK... A strong cold front will pass across the lower Mid-Atlantic on Sunday night into Monday. Snow showers and IFR visibilities and ceilings are likely for BLF and LWB during this time. Flurries or snow showers will be possible at BCB and possibly ROA Sunday night into Monday with potential MVFR ceilings. Northwest winds gusting 25kts to locally 40kts will be possible daily from Monday through at least Wednesday, before wind speeds diminish during the later half of the coming week. && .FIRE WEATHER... As of 300 AM EST Saturday... Most of the service area received a wetting rainfall earlier this morning. Totals were highest along & west of I-77, where at least 0.75" fell, with amounts then tapering down further east to less than 0.25" falling along the crest of the Blue Ridge and points eastward. Fire weather concerns are likely to be lower today than in past days considering the rainfall this morning moistened fuels. Winds will be less than 10 mph from the southwest, occurring under a mixture of high clouds and sunshine and minimum afternoon humidity holding above 40 percent. A strong cold front will pass across the lower Mid-Atlantic on Sunday afternoon and evening, bringing sharply colder air and breezy northwest winds to the area for Monday through Tuesday night. Fire weather concerns will increase early in the week as daytime gusts will range from 25 mph to locally 35 mph across the mountains, and from 15 mph to locally 25 mph across the Piedmont from Monday into Wednesday. This will be combined with mostly clear skies areawide, and minimum humidity potentially falling to 30 percent or lower across the Piedmont, all of which will support the drying of fuels. && .RNK WATCHES/WARNINGS/ADVISORIES...
