100 FXUS61 KRLX 080657 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 257 AM EDT Tue Sep 8 2026 .WHAT HAS CHANGED... Heavy rain will be the primary concern accompanying a cold front later this week. Precipitation chances for the weekend have increased slightly. && .KEY MESSAGES... 1) Warm and placid through Wednesday afternoon. 2) A front brings showers and storms to the area Wednesday night into early Friday. Heavy downpours and training storms could prompt localized flash flooding. && .DISCUSSION... KEY MESSAGE 1... A ridge of high pressure, which is currently in control over the Middle Ohio Valley and much of the southern US, will begin to drift south as a cold front approaches mid week. Despite this retreat, dry weather is expected to persist through Wednesday afternoon. A subtle warming trend will continue through the middle of the week, with daytime high temperatures likely peaking around 5 to 10 degrees above normal each afternoon. KEY MESSAGE 2... Showers and thunderstorms are expected to invade southeast Ohio in advance of a cold front Wednesday night, then precipitation will become more widespread as the forges into the area on Thursday. Bountiful moisture should facilitate heavy downpours, which, combined with the potential for training storms, will raise concerns of localized flash flooding within the area. Best potential for hydro-related issues is likely to be on Thursday. Although model soundings show a decent amount of shear developing on Thursday, cloud cover and early activity are anticipated to limit instability. Consequently, severe potential concomitant with the front should be low. The front shifts south of the area by Friday morning, though lingering moisture may sustain some activity primarily in and near the mountains during the day. A couple of shortwaves then proffer additional opportunities for showers and storms this weekend and early next week. && .AVIATION /06Z TUESDAY THROUGH SATURDAY/... Patchy dense fog may form in some of the river valleys before sunrise this morning; however, much like last night, winds just above the surface should suppress development at most terminals. Generally VFR conditions are then expected during the day, although some lower clouds could prompt brief MVFR ceilings over the mountains. Calm to light surface flow should veer from east to southeast by morning, then turns southerly and remains light throughout the day. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z WEDNESDAY... FORECAST CONFIDENCE: Medium tonight with fog, otherwise high. ALTERNATE SCENARIOS: Fog extent, density and timing could vary overnight. Brief MVFR cigs could occur at KBKW later today.
