079 FXUS61 KRLX 250629 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 229 AM EDT Sat Jul 25 2026 .WHAT HAS CHANGED... 06Z Aviation Forecast Discussion update. Potential for strong to severe thunderstorms late Monday and Tuesday. && .KEY MESSAGES... - 1) Isolated to scattered showers and storms this weekend. - 2) Passing disturbances Monday and Tuesday will lead to scattered showers and thunderstorms. Some could be strong or even severe. Flash flooding is also possible Monday night and Tuesday. && .DISCUSSION... KEY MESSAGE 1... High pressure remains an influence through weekend as it remains parked nearby or overhead leading to drier conditions for most this weekend. A series of weak disturbances are projected to move through each afternoon leading to chances for isolated showers and thunderstorms across the northeastern mountains this afternoon and more scattered activity on Sunday. Severe weather is not expected, but an isolated strong storm cannot be ruled out, especially along the upslope side of the mountains. Temperatures will continue on a warming trend through the weekend with mid to upper 80s this afternoon and Sunday afternoon across the usual warm spots in the lowlands. KEY MESSAGE 2... Shortwave disturbances are still slated to cross the area late Monday and Tuesday leading to an unsettled weather pattern emerging as we start the new week. Most of Monday will be dry, outside of the chance for a decaying MCS that some models show moving across Kentucky and southern West Virginia early in the morning. Whether or not this affects the secondary activation of convection remains unknown, but CAPE is projected to recover to about 1,000-2,000 J/Kg in the afternoon. The latest NAM run has scattered showers and thunderstorms reforming late in the afternoon and through the evening. Some storms may be strong to severe, mostly across our portions of the Ohio River Valley as upper-level support from a jet enters the area. Still many details that need to be ironed out once hi-res guidance gets in range. Flash flooding looks to be an issue with this activity late Monday with rounds of heavy rainfall, but particularly on Tuesday, as PWATs between 1.50" and 2.25" move over the area. The NAM currently shows a swath of an inch to an inch and a half of rainfall being picked up across our Kentucky counties and far northern West Virginia. A drier spell looks to arrive on Wednesday behind this active pattern, spanning the rest of the week as high pressure continues to settle in. Still, isolated chances for afternoon storms will exist due to peak heating and a `dirty ridge` setting up. && .AVIATION /03Z SATURDAY THROUGH WEDNESDAY/... A mix of low stratus and patchy valley fog makes for a bit of a tricky forecast this morning. SCT to OVC CIGs between 2,000 and 9,000 feet AGL will be common across the lowlands with possible patchy BR or FG under any breaks in the clouds. ISO showers are possible until ~09z across the northeastern mountains. Afterwards, expecting IFR and LIFR low stratus to form in its wake. BKW will experience the lowest CIGs, possibly between 100 and 500 feet AGL. EKN is most likely to join in, but southeasterly flow from the sfc to 925MB may be a hindrance. Expecting VFR to resume as any low stratus and fog dissipates by ~13z. FEW to SCT CU fields between 3,000 and 7,000 feet AGL will then form from late morning through the afternoon; 2,000 to 3,500 BKN CIGs are likely into the afternoon at BKW, CKB, and EKN. Winds will be light and variable to calm this morning across the lowlands; light and SE`rly across the mountains. W`rly winds between 4 and 10 knots are expected during the day Saturday. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z SUNDAY... FORECAST CONFIDENCE: LOW this morning, HIGH after ~12z ALTERNATE SCENARIOS: Low stratus and fog could be more impactful than advertised. Low stratus may not manifest at EKN.
