410 FXUS61 KRLX 121736 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 136 PM EDT Tue Aug 12 2025 .SYNOPSIS... Hot with showers and storms mainly south and in the mountains today. Showers and storms more likely as disturbances cross overnight through Wednesday, then more diurnal into the weekend. && .NEAR TERM /THROUGH WEDNESDAY/... As of 130 PM Tuesday... A hot day on tap today with surface high pressure off to the east, and building upper ridge over area. Many locations will top out in the lower 90s today, and that combined with dew points in the upper 60s/lower 70s will result in apparent temperatures in the upper 90s today. An increase in moisture across the area during the period will allow for showers/storms at times, mainly during peak heating hours, although shortwaves traversing the area will also aid in development. Satellite estimates of PW Tuesday afternoon show a large area of close to 2 inch PW just off to the south and west, with this higher moisture content air progged to move into our area by later this evening/tonight. This, with an approaching frontal boundary for Wednesday, along with multiple waves in the flow, will allow for more widespread thunderstorm activity, with the potential for heavy rain taking hold across the area Wednesday, possibly even as early as dawn Wednesday, with heaviest rains looking to be possible across southwest VA and the southern coal fields. A localized flooding risk is possible with these storms. However, due to antecedent dry conditions, elected not to issue a flood watch. WPC has however elected to put the aforementioned areas into a slight risk for excessive. && .SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/... As of 130 PM Tuesday... Showers and storms will continue across the area on Thursday with the boundary lingering over the area, and shortwaves traversing the area. The front will lift back north on Friday, with heat and humidity building across the area again. Less convection is expected on Friday, and overall, should be relatively diurnal in nature. As with previous days, storms will overall be slow to move, and have the potential for heavy downpours. && .LONG TERM /SATURDAY THROUGH MONDAY/... As of 130 PM Tuesday... Chances for showers and storms continue across the area in the extended period, mainly diurnal in nature. Storms will contain heavy downpours, and overall be slow to move in the light flow regime. Localized flooding will be possible, but widespread issues are not anticipated. In addition, chances for severe weather look to be relatively low during the period. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... As of 130 PM Tuesday... Scattered showers and storms expected through 03Z Wednesday, mainly across southwest VA, southern WV and the mountains, although isolated storms possible elsewhere. Expect brief IFR conditions in vicinity of storms due to heavy rainfall. After 03Z, there should be a bit of a lull in the thunderstorm activity, however, patchy fog cannot be ruled out, particularly in any areas that receive rain Tuesday afternoon/evening. In addition, widespread MVFR and local IFR ceilings are forecast to take hold across the area, particularly after 09Z and linger for much of the remainder of the TAF period. In addition, showers and storms should ramp back up again, particularly after 06-09Z Wednesday, with the heaviest of storms expected across southwest Virginia and southern WV. IFR or worse conditions will be possible in vicinity of storms. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z WEDNESDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Forecast adjustments and amendments may be needed for thunderstorms this afternoon, especially in the mountains. Confidence in the overall forecast decreases overnight tonight, with the possibility of heavy showers and thunderstorms, low ceilings, and fog.
