484 FXUS61 KRLX 241633 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 1233 PM EDT Sun Aug 24 2025 .SYNOPSIS... A cold front completes its passage through the area late tonight. High pressure builds behind the front, supplying predominantly dry weather and refreshingly cool temperatures. && .NEAR TERM /THROUGH MONDAY/... As of 1230 PM Sunday... A moisture-starved cold front continues an eastward journey through the forecast area today. The boundary was analyzed to be crossing the Ohio River at the time of writing, with dropping dewpoints down into the 50s noted at upstream observation stations in its wake. That trend is anticipated to sluggishly occur within the Central Appalachians this afternoon and evening as the boundary swings through. The best chance for showers and storms today will be to the east of the forecast area, where the best pre-frontal southwesterly flow is still present. A few lingering showers and perhaps a rumble of thunder may still occur along the northeast WV mountains today, but will grow less likely with time due to the encroaching front. Upon the departure of the front, progged to be sometime overnight into early Monday morning, cold air advection settles in from the west/northwest under the guise of approaching high pressure. This will refresh the area with cool and comfortable temperatures more representative of Fall than the end of August. Predominantly dry weather and daytime highs tumbling down into the 60s and 70s awaits us for the start of the new work week. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/... As of 1230 PM Sunday... High pressure triumphs over the area through the forecast period and will continue to support unseasonably cool temperatures and dry weather across the Central Appalachians. The center of the high will still be back in the Upper Midwest starting Monday night, but its influence will stretch down into the Ohio and Mississippi Valleys, and will maintain its grip over the eastern CONUS as it slides eastward through the course of the work week. During which time, overnight cool temperatures settling over warm river basins will infer patchy to dense river valley fog each morning that will then gradually branch out into fair weather cumulus fields for the afternoon timeframe. Refreshing afternoon temperatures will range in the upper 50s to mid 60s along our mountain zones and low to upper 70s across the lower elevations. Chamber of Commerce weather will therefore be on tap for this upcoming work week. && .LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/... As of 1230 PM Sunday... High pressure remains at the forefront of the long term period, serving up multiple days of dry weather across the region. This feature is progged to be centered overhead by Thursday and then meander over the Great Lakes region and the Ohio Valley through the end of the forecast period. The repositioning of the high will begin to stir up rising temperatures and slightly higher dew points for the latter half of the week as low level flow shifts out of the south. This will encourage high temperatures to reach the low 80s once again in the Tri-State area, returning us to a more seasonable pattern for this time of year. As it currently stands, there remains very little agreement on the timing and location of the next weather maker for here in the forecast area, so therefore little to no rainfall is anticipated after today`s cold front highlighted in the near term period. && .AVIATION /16Z SUNDAY THROUGH THURSDAY/... As of 1230 PM Sunday... The TAF period opens up in the midst of a cold frontal passage. At the time of writing, the front was oriented from north to south along the Ohio River, with the anticipation of the boundary making more progress eastward through the course of the afternoon and evening. The best forcing now resides east of the mountains and will be where most of the showers and storms set up for today. However, a few stray showers remain possible near our mountain terminals this afternoon before the front swings overhead tonight. Therefore, included a few hours of VCTS and EKN and BKW. The front will sluggishly pivot through the area overnight and will supply enough moisture and calm low level winds to produce areas of locally dense valley fog through Monday morning. Fog will remain firmly in place until daybreak and will then gradually erode into afternoon fair weather cumulus. High pressure begins to settle into the area on Monday, which will preclude any active weather for the rest of the work week. VFR conditions will then rule the roost during the daytime hours. Light to calm winds today will shift out of the west in the wake of the frontal passage. Breezy winds may ensue along the mountains Monday afternoon around 15kts.
