412 FXUS61 KRLX 011809 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 209 PM EDT Fri Aug 1 2025 .SYNOPSIS... Cooler, yet comfortable temperatures and drier weather move in this weekend in the wake of a cold front. Gradual warm up and return of humidity occurs next week. && .NEAR TERM /THROUGH SATURDAY/... As of 1220 PM Friday... A cold front remains to our south with a lee trough just to our east. Lingering low-level moisture and cool northwest to northeaster flow will keep maritime low cloud cover over much of the area today. NAM12 soundings suggest pockets of drizzle will occur at multiple locations until late afternoon. Showers and thunderstorms could be possible across the southern mountains of West Virginia and southwest Virginia as a CAPE boundary of 1,000-1,500 J/Kg remains along our border with Blacksburg`s forecast area. Not expecting severe weather in our area today, but localized flash flooding is possible across the aforementioned areas as precipitable water nears 1.7 inches and lack of proper steering aloft leads to instances of training heavy rainfall. There is a marginal risk for excessive rainfall across our southwestern Virginia counties as well as McDowell, Wyoming, Raleigh and Fayette counties in West Virginia. A slight risk remains just to the east of these counties. Temperatures will be much cooler today, but still comfortable with the cold front`s passage. Cloud cover will help to moderate temperatures and dew points will remain in the upper 50s and 60s to provide a less oppressive air mass. High temperatures will be in the 70s to lower 80s across the lowlands, where the later will mostly remain across our Ohio counties and along the Ohio River. These areas will likely see the cloud deck erode going into the afternoon allowing for warmer temperatures. Meanwhile, the mountains will remain in the 60s to the mid 70s. Temperatures tonight will drop back into the 50s to the lower 60s. Low stratus and areas of patchy valley fog will be likely due to trapped moisture near the surface. Saturday will showcase decreasing cloud cover in the afternoon with highs in the upper 70s to lower 80s across the lowlands. Chances for afternoon showers and thunderstorms exist across the southern coalfields and mountains of West Virginia and southwest Virginia where some instability will remain in place. Overall, high pressure will be taking hold of the region with drier weather expected for most locations. The emergence of a slight haze is possible late Saturday with Canadian wildfire smoke being suspended aloft, but impacts to air quality and visibility are not expected. && .SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY NIGHT/... As of 1240 PM Friday... Another night/morning of valley fog and cooler than normal temperatures is expected Saturday into Sunday with high pressure and radiational cooling in full control. Some chances exist once again for afternoon thunderstorms across Kentucky, southern West Virginia, and southwest Virginia; largely anticipating drier weather for most though under the bubble of high pressure. High temperatures will be a bit warmer than previous days with mostly clear skies. The lowlands will range from the upper 70s to mid 80s while the mountains will stay in the mid 60s to the upper 70s. Skies could be hazy at times with smoke aloft, but no impacts are expected. && .LONG TERM /MONDAY THROUGH THURSDAY/... As of 1255 PM Friday... Continued drier weather spell will saunter into Monday with the high parking to our northeast. An inverted trough embedded in the ridge and ahead of a disturbance to our west will increase precipitation chances by Tuesday afternoon and through midweek. The main disturbance will remain to our west though, so not anticipating any activity greater than garden-variety showers and thunderstorms at this time. Instances of valley fog possible each morning, especially with any afternoon rainfall. Warming trend continues into Monday and will last through the week as warmer southeasterly flow moves in. Highs could reach the upper 80s to lower 90s by Friday. Humidity will also be returning too with the warmer, moist flow. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... As of 210 PM Friday... Post-frontal, low-level cloud cover will remain across a bulk of the area with MVFR conditions across the lowlands and IFR or lower spanning the mountains. VFR will take hold this afternoon at sites farther west such as HTS and PKB, maybe even CRW. Showers and thunderstorms are possible across the southern mountains of WV and VA into the evening, but severe weather is not anticipated. Low stratus development and patchy fog will be likely overnight with lingering low-level moisture. IFR or lower conditions will accompany any low clouds or valley fog. VFR will resume by ~13-14z Saturday. Winds will be light and remain NNW to NNE today and tonight. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z SATURDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: MVFR or IFR conditions may remain for a longer period of time than forecasted due to stubborn low ceilings. Timing, location, and intensity of fog and low stratus tonight may vary.
