000 FXUS61 KRLX 230807 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 407 AM EDT Wed May 23 2018 .SYNOPSIS... Cold front pushes south today. High pressure tonight into Friday. More unsettled weather arrives in time for the weekend. && .NEAR TERM /THROUGH TONIGHT/... As of 350 AM Wednesday... A cold front will continue to push southward through the forecast area today. Moisture remains sufficient for some showers in southern and eastern WV and southwestern VA until the cold front pushes through. A high pressure system will build in behind the cold front, providing dry weather tonight. && .SHORT TERM /THURSDAY THROUGH FRIDAY/... As of 400 AM Wednesday... Quiet as high pressure noses in from the north. This feature will shift east on Friday, such that enough return flow moisture may allow an afternoon shower or thundershower across western and far southern counties. Expect dense river valley fog each morning. Central guidance numbers were excepted with not change. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... As of 400 AM Wednesday... All eyes on what happens in the northern Gulf over the next several days. Regardless of whether an area of low pressure becomes tropical in nature, the moisture from this feature will advect northward into the region over the weekend...persisting into early next week. Expect scattered showers/storms on a daily basis, primarily diurnal in nature. With relatively light flow and increasing pwats, downpours will increasingly become capable of enhancing localized flooding concerns. && .AVIATION /08Z WEDNESDAY THROUGH SUNDAY/... As of 150 AM Wednesday... A band of showers will continue to push southward across the area early this morning, providing restrictions ranging from MVFR to LIFR. A cold front north of the line of convection will move through later. In advance of the cold front, some patchy dense fog and/or low stratus are possible. Some MVFR clouds are possible along and behind the cold front. Clouds will raise into a cumulus deck today. Expect VFR conditions this evening.
