531 FXUS61 KRLX 140236 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 1036 PM EDT Sun Jul 13 2025 .SYNOPSIS... Daily chances for mainly diurnally driven showers and thunderstorms continue into the new work week as a warm and moist airmass remains in place. && .NEAR TERM /THROUGH MONDAY/... As of 1035 PM Sunday... A cluster of showers and thunderstorms remains to the west ahead of a front that will be sinking south overnight. CAMs show them weakening as they enter the area, which radar suggests this solution currently too as showers start to enter our northeastern KY counties. Models remain conservative with PoPs as well, though did increase them some along our western periphery overnight where there is higher confidence for some more organized showers to move through. As of 827 PM Sunday... No changes needed to the forecast. Radar shows a few cells remaining at this hour, but overall seeing a decline in strength with the loss of diurnal heating. As of 1125 AM Sunday... Scattered showers and thunderstorms are expected this afternoon, especially across the higher elevations of eastern West Virginia. Short-term model guidance consistently shows PWAT values reaching 1.75-2.00 area-wide. While severe weather is unlikely due to a lack of significant wind shear, an isolated stronger storm or two could develop, bringing localized damaging wind gusts. A cold front will slowly approach the Ohio River Monday, with a 60- 70% chance of stalling along or just west of the river. The NBM model has shown increased confidence in this stalling, leading to a higher probability (50-70%) of increased PoPs across the region for Monday afternoon. Heavy downpours remain a concern with PWATs expected to be at or around 2.00. However, storms should be moving fast enough ahead of the front to prevent widespread flooding issues. An alternate scenario for Monday is the front pushing further east into West Virginia, which could lead to drier conditions along and west of the Ohio River. However, this alternate scenario does not look likely. Expect high temperatures in the middle and upper 80s today and Monday with dew points reaching the middle 70s. Staying hydrated and taking breaks in air conditioning will be necessary when spending extended time outdoors. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/... As of 1128 AM Sunday... For Tuesday, there is a 40-60% probability of rain, primarily concentrated over the mountains. This represents an increase from yesterday`s 10-30% probability, likely influenced by the high- pressure center`s projected position just east of the Appalachians and lingering upper-level energy. Wednesday presents similar probabilities for showers and thunderstorms due to a comparable atmospheric setup. Both days carry an elevated probability of heavy downpours within any developing storms, with precipitable water values ranging from 1.60-1.80. && .LONG TERM /THURSDAY THROUGH SUNDAY/... As of 1129 AM Sunday... Daily shower and thunderstorm chances are highly probable from Thursday through Saturday. A high-pressure system along the Southeast U.S. coastline will channel significant Gulf moisture into the middle Ohio Valley and central Appalachians. While models generally indicate a front approaching the Ohio River between Thursday and Saturday, there is inconsistency regarding its precise timing. Based on the latest runs from the NBM, ECMWF, and GFS, the most probable scenario (supported by a majority of recent model runs, especially the NBM and more recent GFS runs) is that the front stalls over our region, leading to continued rain chances into next weekend. A less likely alternate scenario (supported by earlier model iterations and some ECMWF variability, though it now leans towards stalling) suggests the front pushes through more definitively. This could temporarily decrease rain chances after the frontal passage before renewed moisture advection. && .AVIATION /03Z MONDAY THROUGH FRIDAY/... As of 730 PM Sunday... Scattered showers and thunderstorms will continue for a few more hours, but will dramatically wane with loss of diurnal heating. Restrictions are possible with any thunderstorms. Valley fog is expected to form overnight, especially for locations that received rain today. IFR conditions or lower are most likely to form at CRW, PKB, EKN, and CKB. Most fog will dissipate by ~12z if not earlier due to cloud cover. A cold front will also be approaching from the west after ~06z allowing for a low stratus deck to filter in early Monday morning. Scattered morning showers and eventually afternoon thunderstorms will develop ahead of the front. Winds will be light and SW-W`rly through the period. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z TUESDAY... FORECAST CONFIDENCE: Medium for fog, otherwise high. ALTERNATE SCENARIOS: Timing, location and intensity of showers and thunderstorms could vary from the forecast. Coverage, density and extent of fog tonight may vary given recent rainfall and cloud cover overnight.
