AREA FORECAST DISCUSSION National Weather Service Charleston WV 805 PM EDT Thu Aug 6 2020
SYNOPSIS. A series of disturbances move up the Appalachians through Friday. High pressure crosses Saturday, setting up a warming trend into early next week, as it moves east.
NEAR TERM /THROUGH FRIDAY/. As of 800 PM Thursday .
Elected to increase cloud coverage through the near term period as latest model guidance suggests an uptick in clouds starting late tonight. Also made adjustments to POPs this evening along the mountains as convection wanes with the loss of diurnal heating.
As of 200 PM Thursday .
Showers and storms will continue to develop mainly across the southern and eastern portions of WV and extreme southwest VA through this evening. An upper level shortwave and the afternoon heating acting on PWATs around 1.8 inches are responsible for this activity. Expect most of the convection to wane down by 9 pm this evening. A Marginal risk for excessive rainfall exists across central Appalachians through Friday. Heavy downpours are possible with this activity as well as repetitive showers over the same areas, posing a threat for localized flooding into Friday. Convective activity will diminish considerable tonight, but PoPs still exist across the eastern half of our forecasting area. Patchy dense fog is also expected mainly along the most protected river valleys overnight tonight.
For Friday, a stronger H500 vorticity maxima sweeps across the area to provide better support for showers and storms development mainly during the afternoon and evening hours. WPC has the central Appalachians under a Marginal risk for excessive rainfall as well.
Accepted guidance temperatures with near normal values through the period.
SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/. As of 220 PM Thursday .
The pesky long wave trough finally exits east Friday evening as a broad ridge over the Southern Plains begins to to slide into the region. This will result in warm-up for the weekend with highs across the Lowlands in the upper 80s to lower 90s along with minimal precipitation chances as a subsidence inversion based near H800 develops.
LONG TERM /MONDAY THROUGH THURSDAY/. As of 220 PM Thursday .
Subsidence begins to fade as ridging deamplifies in advance of the next system transiting the Upper Great Lakes with a diurnal risk of showers and thunderstorms returning Monday. Models have shifted this feature a bit further north over the last couple runs, so think Monday's highs will be pretty similar to Sunday's in the absence of stronger southwesterly flow.
The pattern turns more active for the remainder of the week with copious moisture pooling ahead of a stalling frontal boundary somewhere across the Middle Ohio Valley. Low level moisture coupled with strong surface heating will yield substantial instability, although generally weak winds through the column will limit overall severe potential with the main threats being localized damaging winds with core drops and locally heavy rainfall with slow moving storms.
AVIATION /00Z FRIDAY THROUGH TUESDAY/. As of 800 PM Thursday .
Diurnal heating and ripples of disturbances aloft have resulted in scattered showers and thunderstorms, primarily along the spine of the Appalachians. At the time of writing, BKW was receiving a direct hit in flight restrictions due to convection, and can't rule out EKN falling into the same boat. Convection wanes over the next several hours, returning all terminals to VFR for a time.
Confidence severs overnight tonight as river valley fog production contends with increasing cloud coverage aloft. Held onto fog across our most vulnerable sites of CRW, EKN, and CKB, while excluding HTS and PKB with this issuance. Will also have to monitor BKW for fog now that the terminal has observed rain this evening.
A similar forecast is painted for Friday with convection sprouting in the afternoon, potentially in close vicinity to our mountain aerodromes. For now, chose to include VCTS at BKW to account for this. Winds remain light throughout the period.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z SATURDAY . FORECAST CONFIDENCE: Medium.
