000 FXUS61 KRLX 250705 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 305 AM EDT Thu May 25 2017 .SYNOPSIS... Upper level low over Ohio Valley will move east across the area bringing chances for showers and storms through Friday. Additional disturbances provide precipitation chances over the weekend. && .NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
As of 300 AM Thursday... An upper low pressure system will move east from the Ohio Valley, east across WV through tonight. This track could bring additional rainfall to the area. In fact, high resolution and synoptic models are in agreement on a strong vorticity max that will sweep across the area this afternoon. Soils across the southern half of WV are near saturated, and the area is in a marginal risk for excessive rainfall. It will take less rainfall to produce flooding problems. Therefore, issued a Flash Flood Watch for counties across central and southern WV, and extreme southwest VA through this evening.

&& .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... As of 350 PM Wednesday... Upper level low will move off to the northeast Thursday night and Friday, with showers pulling out of the area. Models are fairly consistent with a disturbance then moving through Friday night into Saturday, providing additional showers, with thunderstorms possible by Saturday afternoon. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... As of 350 PM Wednesday... Models show a disturbance moving across the area Saturday night or Sunday. Depending on the timing of this disturbance, could see some decent CAPE for Sunday afternoon. Will need to keep an eye out for the possibility of hail. Models then diverge a bit with the timing of a cold front for early next week. This leads to a low confidence forecast for the timing of precipitation Monday and Tuesday, in addition to temperatures during this time frame. By Wednesday, cooler air from an upper level trough should be over the area with a few showers not out of the question. && .AVIATION /07Z THURSDAY THROUGH MONDAY/...
