... Winter weather system continues affecting the area through tonight. High pressure builds to begin the weekend. A series of weak fronts crosses Sunday through Tuesday. High pressure midweek.
NEAR TERM /UNTIL 6 AM FRIDAY MORNING/... As of 900 PM Thursday...
Have gotten some reports of 0.5 to 1 inch of snow in NE KY so did a quick update to add a bit more snow accumulation with the area of better reflectivity currently crossing the Tug Valley. This should push through southern WV over the next several hours with generally 0.5-1 inch of snow. Would expect this to mainly be on grassy and raised surfaces.
As of 240 PM Thursday...
Winter low pressure will cross the area from west to east tonight. Radar imagery and high resolution model data suggest a lull in pcpn, associated with a dry slot, spreading from south to north across extreme southwest VA, and the KY and WV border this evening. Although pcpn coverage and intensity is expected to decrease through 00Z Friday, additional pcpn, associated with wrapped around moisture from the low center, is expected over portions of southeast OH, spreading west over WV, and lingering over the northeast mountains through early Friday morning. Temperatures will drop a degree or two overnight. Models consensus suggest CAA at H850, with the minus 5C line well south of our cwa by 06Z Friday. These temperatures will likely switch P-Type to all snow over the central and northeast mountains, with lesser amounts over portions of southeast OH and lowlands of WV through 12Z Friday.
As the cold air arrives, areas of pcpn will diminish in coverage and begin exiting the central and northeast mountains towards mid morning Friday. Upslope snow accumulations will range from from 1 to 4 inches over the northeast mountains, with locally heavier amounts over the highest peaks.
Winter Storm Warning continues in effect for the eastern slopes of WV due to pockets of FZRA through 00Z Friday.
Went with NBM temperatures through the period. Expect sub freezing temperatures area wide overnight. This will tend to freeze any runoff water over roads.
SHORT TERM /6 AM FRIDAY MORNING THROUGH SUNDAY NIGHT/... As of 235 PM Thursday...
Lingering low level moisture beneath a stout inversion may keep stratus around for much of Friday, especially across northern counties. Just enough lift in the morning for some light precip across the northern mountains. Model soundings suggest crystal growth conundrums amid the aforementioned subsidence inversion. I will leave it as snow for now, but freezing drizzle may have to be eventually added.
Dry air will overwhelm much of the column Friday night, though the lingering inversion should allow for fog and/or stratus to redevelop across much of the region.
Any fog/stratus should dissipate later Saturday morning, with sunshine returning for what should be splendid afternoon. Temperatures will still run a bit below average, however.
After a chilly night, mid and high level clouds will stream in ahead of the next s/w trof. Lift will increase as the trof and cold front approaches Sunday night, with a frontogenetically forced band of light precip developing across the area. Some of this may take the form of a mix with wet snow across northern counties, but should not amount to much. A coating is possible across the northern mountains, however.
This system pushes out Monday with sunshine returning. Temperatures to remain below normal.
LONG TERM /MONDAY THROUGH THURSDAY/... As of 211 PM Thursday...
High pressure nestles its way back into Central Appalachia on Wednesday in the wake of Tuesday's moisture starved cold front. Clear skies overnight will allow for ample radiational cooling to occur, leading to chilly mornings each day. Models are hinting at a warm up for the end of the period, as southerly flow invites warmer temperatures back into the forecast.
