327 FXUS61 KRLX 150525 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 125 AM EDT Tue Jul 15 2025 .SYNOPSIS... Daily chances for mainly diurnally driven showers and thunderstorms continue through the week as a warm and moist airmass remains in place. && .NEAR TERM /THROUGH TODAY/... As of 924 PM Monday... Nothing of significant note to change with the forecast. Convective activity has all but dwindled at this hour with only a few straggler showers remaining across the lowlands. Valley fog is expected to manifest in earnest tonight, in the wake of the heavy dosage of rainfall received this afternoon. As of 447 PM Monday... Conveyor belt of showers and thunderstorms will continue into the evening with heavy rainfall and cloud to ground lightning being the main threats. PWATs are between 1.7" and 2.1" across the area, so training showers and thunderstorms will lead to instances of flash flooding. CAPE values between 2,500 and 3,000 J/Kg, high theta-e presence, and weak shear (less than 10kts) will lead to pulse-oriented thunderstorms with high and efficient rainfall rates. Did increase coverage and density of river valley fog tonight as well due to the rainfall and moisture that will remain trapped at the surface. As of 1207 PM Monday... Warm, humid and unstable continues to be the name of the game in the near term period. Frontal boundary just to our north should sag a little farther south today towards the Ohio River vicinity. Showers and storms, already apparent on radar, will continue throughout the near term, both from passing weak waves and heating. Very heavy rainfall can be expected with any storms, with observed PW values around the 2 inch mark across much of the area. Overall, no significant severe weather threat is anticipated, however, an isolated strong to severe storm cannot be completely ruled out, with a damaging wind threat owing to precip loading. Frontal boundary may move slightly north on Tuesday, with the continuation of the warm, humid, unstable conditions, with shower and storm activity ramping back up in the afternoon hours again. && .SHORT TERM /TONIGHT THROUGH THURSDAY NIGHT/... As of 1207 PM Monday... Wednesday and Thursday look to remain unsettled across the area. A low pressure system will move into, and eventually east across the Great Lakes region during the period, dragging a front closer to the area towards the end of the period. Multiple shortwaves moving through the area will trigger showers and storms at times, with heavy downpours. There is the potential we could hit heat advisory criteria on Wednesday and Thursday afternoons, but afternoon storm activity could damper this. && .LONG TERM /FRIDAY THROUGH MONDAY/... As of 1207 PM Monday... Unsettled weather continues in the long term period, with a continuation of the warm and humid conditions, with showers and thunderstorms. && .AVIATION /06Z TUESDAY THROUGH SATURDAY/... As of 125 PM Monday... IFR/LIFR ceilings and visibilities are expected for most terminals as fog continues to develop early this morning. Flight conditions will then improve to VFR after fog dissipates shortly after sunrise. Scattered showers and thunderstorms are expected to sprout up across portions of the area this afternoon, potentially leading to brief CIG/VIS restrictions in any heavier rain. Activity should lessen Tuesday night. Some patches of fog could be possible late in the TAF period, though extent will depend on how much clearing occurs. Flow remains calm into the morning, then light and variable winds are expected through the day. Occasional gusts could occur in storms this afternoon. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z WEDNESDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Timing, location, and intensity of overnight fog and afternoon showers/storms may vary from forecast.
