357 FXUS61 KRLX 052359 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 759 PM EDT Sat Sep 5 2026 .WHAT HAS CHANGED... 00Z aviation discussion... 18Z aviation forecast discussion. Additional thunderstorm development is possible later this afternoon and evening, but new severe potential is questionable, and will depend on the amount of destabilization that occurs later today. This is discussed in Key Message 1. && .KEY MESSAGES... 1) This morning`s convection has largely stabilized much of the atmosphere. Breaks in the clouds later today may allow for new development during the late afternoon and evening, but severe potential is questionable. 2) A break from the heat and humidity is expected through the middle of next week in the wake of a cold front. && .DISCUSSION... KEY MESSAGE 1... A cold front is pushing southward across the forecast area today with showers and a few strong thunderstorms ahead of it. Much of this thunderstorm activity has already exited northern and central West Virginia, southeast Ohio, and northeast Kentucky, but a line of strong to severe thunderstorms will impact portions of southwest Virginia and far southern West Virginia through the late morning and midday hours. The widespread convection that occurred earlier this morning has largely stabilized the atmosphere, leaving overcast to broken stratus in its wake. Latest high resolution model runs are largely in agreement today, showing redevelopment of spotty showers and thunderstorms late this afternoon, after 20Z. Additional severe potential during the late afternoon and evening is questionable, and will likely depend on how much the atmosphere destabilizes later today, if at all. Mid-level dry air can be seen on GOES water vapor imagery across the Great Lakes, moving north to south. This dry air should approach the forecast area Sunday, bringing drier conditions through at least Wednesday with high pressure in control. KEY MESSAGE 2... Much more comfortable air for early September will return Sunday in the wake of a cold front. Expect temperatures in the lower to middle 80s for daytime highs and dew points in the 60s. The comfortable, less humid air should stick around through at least Tuesday. The 500- mb ridge axis will shift eastward again Tuesday into Wednesday, bringing the return of heat and humidity for the second half of the work week. Models show the potential for a few mid-level disturbances to cross Thursday and Friday, which may signal the return of more showers and storms. && .AVIATION /00Z SUNDAY THROUGH THURSDAY/... The remaining isold showers and thunderstorms should generally move out of the area by 03-06Z. Expect the possibility of brief MVFR and IFR restrictions associated with any shower/storm. Otherwise, areas of fog and low stratus are expected to develop across the area tonight, with widespread IFR and areas of LIFR restrictions possible, along with local VLIFR. Confidence is medium at this point in the coverage and extent of these conditions. After 14Z, expecting a return to VFR conditions with light winds area wide, although mountains may be slightly slower to improve to VFR in some spots. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z MONDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Timing and restrictions associated with fog/stratus overnight and early Sunday morning may vary.
