515 FXUS61 KRLX 121916 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 316 PM EDT Sun Oct 12 2025 .SYNOPSIS... A coastal low brings the chance for isolated showers across the mountains through tonight, with dry conditions elsewhere. Area- wide dry weather returns for the new work week. && .NEAR TERM /THROUGH MONDAY/... As of 300 PM Sunday... The region finds itself under a mixture of clear (far west) to overcast (southeast) skies this afternoon as a 996 mb coastal low works northeast just off the North Carolina coast. This system will continue to slowly shift northeast through Monday, gradually interacting/absorbing an upper level disturbance currently across the northeast. Locally, this results in mainly increased cloud cover today/tonight, along with the potential for ISOLD showers/sprinkles in and near the mountains, with the `best` potential (30-40%) being along the eastern slopes of the mountains with upslope flow. Dry weather returns on Monday outside of a highly isolated shower/sprinkle across the northeast mountains, with mostly sunny skies central/west, while mostly cloudy skies linger across the northeast as the aforementioned upper disturbance pivots through. High temperatures today will range from the upper 60s to mid 70s across the lowlands, with 50s to mid 60s in the mountains. Lows tonight will be in the 40s for the vast majority of the CWA. River valley fog will once again develop tonight, especially across the lowlands, southern coalfields, and southwest Virginia. Fog will be dense in spots, likely being stubborn to burn off Monday morning given the time of year. High temperatures on Monday will be similar to that of today. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY/... As of 300 PM Sunday... Area-wide dry weather persists through the short term period as upper-level ridging tries to build into the region Monday night and Tuesday. A weak shortwave on the periphery of the ridge will then push a dry cold front through the region late Tuesday night into Wednesday. Above normal temperatures on Tuesday (~ 5 degrees) amid mostly sunny skies will transition to near normal on Wednesday given the front passing through with increased cloud cover. Lows Monday and Tuesday nights will be near normal, with 40s progged for most of the forecast area. River valley fog will be possible each night. && .LONG TERM /WEDNESDAY NIGHT THROUGH SATURDAY/... As of 300 PM Sunday... Building/traversing surface high pressure following the passage of the aforementioned cold front will result in a continuation of widespread dry weather Wednesday night into Saturday amid mostly clear skies given rather dry low/mid levels. High temperatures on Thursday will be ~ 5 degrees below normal, with 60s across the lowlands, while 50s in the mountains. A favorable radiational cooling setup Wednesday/Thursday nights will result in frost potential, especially on Thursday night when widespread 30s are expected across the forecast area, with upper 20s across the mountain valleys, perhaps even some of the typical lowland cold spots. River valley steam fog is also expected given a large water/air temperature difference. A warming trend will begin on Friday as high pressure shifts east and return flow begins in advance of the next disturbance approaching from the west. High temperatures on Friday will sneak above normal, with well above normal temperatures currently progged for Saturday, nearing 80 in some locations. While well down the road, continued dry conditions throughout the work week may lead to at least slightly elevated fire weather conditions by late in the work week and particularly the weekend as the pressure gradient tightens in advance of the next system, with the next chance for rain not until late Saturday or Sunday. && .AVIATION /18Z SUNDAY THROUGH FRIDAY/... As of 150 PM Sunday... Mainly VFR conditions persist today amid SCT to OVC skies across the mountains and portions of the lowlands. MVFR CIGs are possible across the mountains, with MVFR CIGs progged for BKW, while potentially affecting EKN. ISOLD showers/sprinkles are possible into tonight in/near the mountains, but are not anticipated to result in any VSBY restrictions. Restrictions will become more widespread overnight courtesy of river valley fog and some stratus (in the mountains). Overall, fog coverage is expected to be more widespread than last night, with LIFR/VLIFR restrictions currently progged for CRW/HTS/PKB. MVFR restrictions are also progged for BKW/EKN, but more so due to low stratus. Fog/stratus slowly lifts/dissipates throughout Monday morning, with a return to VFR from ~13-15Z. MVFR stratocu may linger at EKN through the TAF period. Flow will be somewhat variable today, but in general will have a NE`rly component. Gusts between 15 and 20 knots are possible at CKB/EKN/PKB. Calm or light NNE flow is expected tonight. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z MONDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Timing and extent of restrictions overnight into Monday morning with river valley fog and low stratus may vary from the forecast.
