471 FXUS61 KRLX 251825 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 125 PM EST Tue Nov 25 2025 .SYNOPSIS... Low pressure brings showers into Wednesday. A strong cold front on Wednesday brings gusty winds and much colder conditions for Thanksgiving, and into the start of the weekend. && .NEAR TERM /THROUGH WEDNESDAY/... As of 125 PM Tuesday... A complex low pressure system impacts the area through Thursday. The NAM suite has backed off on QPF for the Kanawha Metro Valley this afternoon, in associated with the warm front and mid-level trough associated with the southern stream component of the system. The NAM suite is now in agreement with CAMs, global models and central guidance, which show the heaviest amounts over northern portions of the middle Ohio Valley. These amounts of one half to three quarters of an inch will be easily manageable outside visibility restrictions and hydroplaning. The rainfall of concern early this afternoon was more evenly distributed across the lowlands, and was amounting to up to a tenth of an inch an hour and two tenths in three hours, and will not last much longer than that in any given location. Surface flow and temperatures were struggling to increase early this afternoon, as is not uncommon ahead of a warm front. The widespread rain transitions to showers this afternoon with less coverage through tonight, as a weak cold front associated with the southern stream low crosses. A rumble of thunder cannot be ruled out across far southern portions of the forecast area ahead of this front this evening, as depicted by the Day One Convective Outlook out of SPC. However, instability is limited in degree and depth. An arctic front associated with a northern stream mid/upper- level low that crosses the upper midwest tonight and Great Lakes Wednesday, crosses the forcast area on Wednesday. The front will be followed by gusty winds and falling temperatures. The mild air remains in place into Wednesday morning, before falling from the 50s into and through the 40s from west to east during the midday and afternoon hours on Wednesday. Low level moisture settling in tonight will also be flushed out by the arctic front. && .SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/... As of 125 PM Tuesday... Cold characterizes this period, so the warmth of ovens on turkey day will be welcome, with mother nature providing a large, free refrigerator/freezer for leftovers. A strong post frontal inversion explains the modestly low heights compared with how cold it will be at the surface, with lowland highs only in the 30s on Thursday and especially Friday. Temperatures should drop below freezing throughout the forecast area by dawn turkey day, and then drop well into the 20s Thanksgiving night, teens in the higher terrain. The depth of the mixed layer beneath the inversion varies, the top of it reaching the lower to middle portions of the favored dendritic growth temperature range, allowing for at least flurries at least in and near the mountains. The best chance for snow showers there is Wednesday evening as the mid/upper level trough behind the cold front crosses, and then again late Thursday night into Friday morning, when a mid-level short wave trough crosses, the mixed layer being deepest beneath these features. Strong winds behind the cold front will gust toward 40 mph in interior southeast Ohio Wednesday, and to 50 mph across the higher ridges Wednesday night into Thursday. There, both the HREF and the probabilistic NBM show well over a 50 percent chance for wind gusts exceeding the 46 mph advisory criteria Wednesday night into Thursday morning, but probabilities of getting gusts over the 58 mph warning threshold are much lower. As a result, would expect needing a Wind Advisory for the at least the northern mountain zones for Wednesday night. These strong winds will diminish a bit Thursday, but another uptick is likely over the higher terrain Thursday night, before winds gradually diminish on Friday. Apparent temperatures will dip into the single digits across the higher mountainous terrain Wednesday night, and remain there through Friday. && .LONG TERM /FRIDAY NIGHT THROUGH MONDAY/... As of 125 PM Tuesday... After a dry, cold start, the long term brings a cacophony of forecast issues. The high representing the center of the arctic air mass is forecast to be parked right over the area Saturday morning, perfect for radiative cooling that will send temperatures down into the teens across much of the area. The balance of the weekend brings moderating temperatures as the next low pressure system moves into the area. While this system will track north of the area on Sunday, precipitation associated with it could take a wintry mix as it moves into the area Saturday night, before turning to rain on Sunday. The cacophony begins Sunday night, with colder air moving in behind the system as precipitation ends, and then central guidance not yet able to resolve a dry period before the next system rolls in around the middle of next week. While models are in fairly good agreement on high pressure behind the weekend system crossing on Monday, they then diverge widely on the track and timing of the next system. Solutions generally range from a flat wave passing southeast of the forecast area, to a more amplified system possibly tracking to the northwest of the area. The upper level pattern next week will be progressive, with modestly low heights over the area, and temperatures modestly below normal at least early on. && .AVIATION /15Z TUESDAY THROUGH SATURDAY/... As of 125 PM Tuesday... Rain associated with a warm front this afternoon will bring MVFR conditions at times. The widespread rain moves out of the area late this afternoon into this evening, leaving behind more widely scattered showers, as a weak cold front associated with the same parent low pressure system crosses. Ceilings will tend to lower to MVFR later this afternoon and evening, and eventually to IFR overnight tonight. However, low level flow will be sufficient to prevent much more than occasional MVFR visibility. An arctic front crosses on Wednesday, followed by gusty winds but rising ceilings, which should reach VFR for most if not all but the higher terrain by the end of the TAF period, 18Z Wednesday. Any visibility restrictions should improve quickly to VFR after daybreak Wednesday. Southeast surface flow, gusty at BKW and gusty at times along the Oho River, but light elsewhere early this afternoon, allowing possible low level wind shear CRW, CKB and EKN. Surface flow will become south this evening and light southwest overnight, before becoming west to southwest behind the arctic front on Wednesday, with gusts increasing to at least 25 kts by the end of the TAF period, 18Z Wednesday. Moderate to strong southwest flow aloft this afternoon will be moderate southwest tonight and Wednesday. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 12Z WEDNESDAY... FORECAST CONFIDENCE: Medium to high. ALTERNATE SCENARIOS: Timing of rain and associated restrictions may vary from forecast. Ceilings and visibility outside rain showers may vary overnight tonight into Wednesday morning. Gusty winds behind the arctic front Wednesday will fluctuate.
