AREA FORECAST DISCUSSION National Weather Service Charleston WV 1055 PM EST Fri Dec 12 2025
SYNOPSIS
Widespread accumulating snow late Saturday into Sunday with a strong clipper. Bitter cold Sunday and Monday following the passage of an arctic front, then moderating temperatures through midweek.
NEAR TERM /THROUGH SATURDAY/
As of 1040 PM Friday...
Areas of fog have quickly developed across the valleys of southwest VA and the southern WV coalfields. With temperatures in the mid 20s to low 30s, have issued an SPS for these locations to highlight the potential for slick spots via freezing fog / black ice.
Otherwise, the forecast remains on track, with the arctic front gradually shifting southeast across the midwest CONUS, with the next Alberta Clipper quickly diving southeastward through northeast Montana.
As of 740 PM Friday...
A quiet evening across the region in advance of the next winter storm. Dry weather continues overnight amid lingering patches of low stratus, as mid/high level clouds begin to stream overhead from the northwest. The only noteworthy update to the forecast this evening was to add in the potential for patchy fog / freezing fog across the valleys of southwest VA and the southern WV coalfields where some snowmelt occurred this afternoon resulting in some stagnant low-level moisture.
Otherwise, the rest of the forecast remains on track.
As of 135 PM Friday...
Snow has tapered off across the south with the exit of the initial clipper. Drier conditions will take hold across the area for tonight, although could still see some lingering light precipitation across the mountains tonight and early Saturday out ahead of the next system, which will move into the area by Saturday afternoon/evening. Snow ratios will generally start out somewhat low, 12:1 to 14:1, but will increase across the area by Saturday night into Sunday as colder air works into the region, generally increasing to 18:1 to 21:1 by then. This will allow snow to easily pile up/accumulate. The winter weather headlines have been issued to include a winter storm warning for most areas, except across the extreme south where lesser amounts are expected. The mountains in particular will see decent snowfall accumulations as a period of nw upslope flow continues beyond the near term period, and it's possible, amounts may need to be increased with subsequent packages. Have the northern mountain zones warnings going into Sunday to account for upslope, but may need to be extended in time depending on what happens.
SHORT TERM /SATURDAY NIGHT THROUGH MONDAY NIGHT/
As of 500 PM Friday...
Have issued an Extreme Cold Watch across the higher terrain of Pocahontas and Randolph Counties from 4 AM Sunday until 10 AM Monday for wind chills as low as 25 below zero. The coldest of wind chills are expected Sunday afternoon through Sunday night, especially across the higher mountain ridges, where wind gusts of 35-45 mph are possible at times. Cold Weather Advisories will likely be needed across the lower mountain elevation zones as we get closer to the event. The rest of the forecast remains on track.
As of 140 PM Friday...
Snow will continue Saturday night into early Sunday as moisture fetch sets up off the Great Lakes, and a northwesterly upslope flow takes hold across the area. Additional light accumulations are possible across the lowlands, with continued accumulating snows expected across the mountains, particularly with the overall fluffy nature to the snow. Much colder air filters in for Sunday as the upper trough sags south across the area, with temperatures falling Sunday into the teens area wide, single digits in the mountains. This, combined with winds, will result in wind chills in the single digits across the lowlands, and will necessitate cold weather headlines across the mountains, which may be lumped into any winter storm headlines issued.
Conditions will gradually dry out late Sunday night into Monday as high pressure nudges in. Quite cold conditions are expected Monday morning, with single digit temperatures expected area wide, below 0 in the mountains.
LONG TERM /TUESDAY THROUGH FRIDAY/
As of 140 PM Friday...
Extended period continues to trend drier, with high pressure in control. Temperatures will also moderate towards mid week, with the possibility of temperatures climbing above normal towards the end of the period.
AVIATION /03Z SATURDAY THROUGH WEDNESDAY/
As of 705 PM Friday...
A mixture of VFR/MVFR across the area at present with some patches of MVFR stratus meandering around in and near the northern mountains, along with across the Mid-Ohio Valley.
Expect this trend to continue overnight, with a gradual increase of more MVFR shifting southeastward by late tonight, although confidence in this is only medium. A bit of IFR in/near the mountains cannot be entirely ruled out. Otherwise, dry conditions persist overnight, with perhaps a bit of patchy freezing fog developing across southwest VA and the southern WV coalfields where some snowmelt occurred today.
MVFR/IFR CIGs are expected on Saturday as the next system moves in from the north bringing snow to the far northern terminals towards the end of the TAF period. This results in the potential for IFR/LIFR VSBY restrictions at CKB/EKN/PKB. Dry conditions are progged at BKW/CRW/HTS through the end of this TAF period, but snow will shift south into these areas on Saturday night.
Light surface winds during the period, although occasional gusts in the mid teens across north central WV are possible on Saturday, slightly higher in the mountains. WSW surface flow early on Saturday will veer to W/WNW by the end of the TAF period.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z SUNDAY...
FORECAST CONFIDENCE: Medium.
ALTERNATE SCENARIOS: Timing of lowering CIGs overnight may be slower than currently forecast. Brief IFR could occur at BKW/CRW/EKN late tonight through Saturday morning.
