AREA FORECAST DISCUSSION National Weather Service Charleston WV 1231 PM EST Tue Jan 19 2021

SYNOPSIS. A disturbance moves through today bringing chances for snow. Weak cold front brings additional snow showers mainly northeast mountains tonight into Wednesday. High pressure end of the week.

NEAR TERM /THROUGH TONIGHT/. As of 1001 AM Tuesday .

Dropped the Winter Wx Advisory for the western CWA and will likely be able to drop the remaining area before 1pm expiration. Forecast remains on track, mostly. Focus with afternoon package will be on additional snow potential tonight for area mountains.

As 817 AM Tuesday .

Expanded Winter Wx Advisory into Fayette and Nicholas Counties, per coordination with WFO RNK. Bands of snow persist along the I-64 corridor this morning and with temperatures colder across Fayette/Nicholas counties, travel impacts are likely to be greatest there.

As of 735 AM Tuesday .

Have increased POPs quite a bit through mid morning, primarily for the northern 2/3 of the CWA. Bands of snow, moderate at times, continue to blossom along/north of the I-64 corridor. Sfc temps are at/just above freezing, thus most snow accumulations are generally expected to occur on elevated and grassy surfaces. Bursts of heaver snow will briefly drop visibilities and produce a quick 1/2 inch of snow before conditions improve. Current plan is to generally hold off on any Snow Squall Warning issuances this morning, owing mainly to warmer road conditions. However, a locally more intense burst of snow may yet require one or two SQWs through mid morning.

As of 251 AM Tuesday .

Middle level flat wave and upper level jet will produce periods of snow showers today.

Models point to an axis of snow affecting the Tri-state area during the morning rush hours with 1 to 2 inches possible. Localized higher amounts will be possible with repetitive snow bands into this afternoon. Therefore, a winter weather advisory is in effect for northeast KY, portions of the Middle Ohio Valley and from the Tri- state area east into Kanawha and Calhoun counties in WV through this afternoon.

Temperatures are expected to warm some, into the lower 40s by this afternoon. This will help to alleviate impacts in snow accumulations by this afternoon. Snow will likely transition to rain along the lowlands later this morning as this system moves out. However, cold air advection behind this system will bring sub-freezing temperatures for the entire area tonight.

There could be a lull in snow showers coverage and intensity later this afternoon and evening, mainly across the southern half of the area. However, a northern stream shortwave will cross the northern half of our region tonight. This feature will push a cold front, bringing another shot of snow showers across the northern portions of the state, particularly across the northeast mountains. 2 to 4 inches of snow with localized higher amounts will be possible tonight into Wednesday morning in these locations. Therefore, a winter weather advisory is in effect for Randolph and northeast Pocahontas counties until Wednesday afternoon.

SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/. As of 346 AM Tuesday .

Upslope snow showers in the mountains will be ongoing at the start of the period on Wednesday morning as a mid level trough departs off to the east of the area. Snow showers are expected to taper off by about mid afternoon as surface high pressure in the lower Mississippi Valley brings drier air into the area. A non-diurnal trend in temperatures is then expected Wednesday night into Thursday as a brief period of warm air advection and a weak mid level wave possibly bring just enough moisture/lift into the area to support a low chance of precipitation across far southeastern parts of the CWA. If this were to materialize, a brief period of light snow or a rain/snow mix would be possible Thursday morning before transitioning to rain showers by the afternoon hours across southern WV and southwest VA, but conditions should be dry elsewhere for the day. With the bulk of the moisture associated with this system expected to be south of our area, will keep PoPs around 20 percent as there is some ensemble support for precipitation to reach our far southern counties, but little to no accumulation is expected. Otherwise, Thursday will be our warmest day of the week with highs reaching the mid/upper 40s across the lowlands and upper 20s to low 30s in the higher elevations.

LONG TERM /FRIDAY THROUGH MONDAY/. As of 346 AM Tuesday .

Surface high pressure in the northern plains late week will build eastwards towards the Great Lakes into the weekend and this should keep conditions dry on Friday and Saturday, but temperatures are expected to be below normal. Temperatures will then start to moderate late weekend into early next week as high pressure shifts off to the east return flow brings some warmer air into the area. In addition, precipitation chances will increase late Sunday into Monday as models show a low pressure system approaching the region during this time.

AVIATION /17Z TUESDAY THROUGH SATURDAY/. As of 1223 PM Tuesday .

VFR to prevail nearly areawide this afternoon and evening, but flight rules are prog to deteriorate overnight.

Morning snow showers have diminished with clearing skies occurring across much of the area. Clearing should persist through the afternoon with any remaining cloud cover resulting in only VFR. Tonight, a fast moving system will send a sfc cold front across the area with areas of snow developing for the second half of the night. KEKN/KCKB likely to have worst impacts with LIFR and IFR conditions prevailing during periods of more moderate snowfall. Elsewhere, lighter snow occurrence is expected, but KCRW/KBKW/KPKB/KHTS are all likely to experience at least some reduction in flight rules at times.

Precip should gradually come to an end Wed morning, but flurries will likely prevail at times. CIGs will gradually rise with a large area of VFR possible just beyond the valid 18z TAF period.

SSWrly sfc winds to 5 to 10 kts this afternoon, becoming WNWrly overnight 10 to 15 kts, gusting to around 20-25 kts at times.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z WEDNESDAY . FORECAST CONFIDENCE: High.

ALTERNATE SCENARIOS: Timing of onset of snow overnight may differ a couple of hours from what TAFs indicate.
