778 FXUS61 KRLX 141814 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 214 PM EDT Mon Sep 14 2026 .WHAT HAS CHANGED... 18Z Aviation Discussion Update. Otherwise, forecast remains on track with previous cycles amid high pressure and warming temperatures. && .KEY MESSAGES... 1) High pressure establishes itself over the area through midweek, promoting dry weather and warming temperatures. 2) Turning active once more beginning on Thursday with the arrival of a cold front. The front is progged to stall in close vicinity to the forecast area late in the week into the weekend, serving up daily chances of showers and storms. && .DISCUSSION... KEY MESSAGE 1... Satellite imagery shows one final patch of stratus eroding across the southwestern portions of the forecast area this afternoon, with cumulus fields and sunshine prevailing elsewhere. High pressure takes center stage for the first half of the work week, beginning over the Great Lakes today and gradually sliding towards the eastern seaboard for Tuesday and Wednesday. Coupled with upper level ridging aloft, mostly dry weather is anticipated to rule the roost through midweek. In the process of the surface high`s eastward journey, a warming trend is set to ensue. A taste of fall is currently underway today across the Central Appalachians, with daytime highs in the 70s and dew points in the 50s/60s. Temperatures more indicative of summertime then triumph over the region for the rest of the work week. Heat and humidity will impose afternoon heat indices stretching back into the upper 90s for many locations across the lowlands by Wednesday and Thursday. KEY MESSAGE 2... The second half of the work week into the weekend turns more active as the upper level ridge breaks down and allows a front boundary to drape down from the north. While uncertainty remains on whether the front makes a complete passage through the area then returning as a warm front or wobbles overhead through the upcoming weekend, model ensembles signal daily chances of showers and storms within the presence of this boundary. Embedded shortwaves flowing along the front will serve up potential for severe weather and flash flooding concerns across the Ohio Valley at times, consistent with previous active patterns the region has faced within the past month. && .AVIATION /18Z MONDAY THROUGH SATURDAY/... Lingering stratus from a cold front continues to branch out into afternoon cumulus fields, parked around 30-40kft AGL. High pressure settling in today kicks off a stretch of dry weather through midweek. During this time, generally quiet daytime flight conditions are anticipated, with river valley fog development during the overnight hours. Fog is first likely to develop around EKN late tonight, then slowly crawl down towards CRW and PKB by Tuesday morning. Morning fog erosion then branches out into another afternoon of fair weather cumulus. Northerly winds this afternoon will gradually veer out of the southeast overnight into Tuesday. A slight uptick in gusts, nearing 20 knots, may also be observed along the mountains early Tuesday morning before diminishing with the establishment of the surface high.
