276 FXUS61 KRLX 080917 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 517 AM EDT Tue Sep 8 2026 .WHAT HAS CHANGED... Updated 12Z aviation discussion. 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 /09Z TUESDAY THROUGH SATURDAY/... Patchy fog will dissipate in the next couple of hours, then VFR conditions are generally expected to prevail across the area today. The one exception may be in brief MVFR ceilings along the mountains this afternoon. For tonight, MVFR or worse restrictions may be possible as patchy fog begins to develop under calm to light surface flow. However, some clouds and stronger flow just above the surface should help prevent fog from becoming widespread. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z WEDNESDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Brief MVFR cigs could occur at KBKW today. Fog extent and intensity could vary overnight.
