900 FXUS61 KRLX 170957 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 557 AM EDT Thu Jul 17 2025 .SYNOPSIS... A tropically influenced airmass remains over the region with numerous weak disturbances passing through. Locally heavy showers and storms are possible each afternoon into next week. && .NEAR TERM /THROUGH TONIGHT/... As of 555 AM Thursday... Isolated showers continue to move across the eastern part of the CWA this morning. Have refreshed PoPs to account for this activity. As of 350 AM Thursday... Key Point: * A Flood Watch is in effect this afternoon into tonight. The forecast area remains entrenched within a warm, moist, and unstable environment while a front approaches from the north today, and then slowly descends into the area overnight. Meanwhile, predominantly zonal flow is expected in the upper levels. Showers and thunderstorms are expected to spread across the area during the day, with most robust activity occurring through the afternoon and evening. A passing shortwave may then help to sustain activity overnight. A combination of wet antecedent conditions and additional heavy rainfall raises the risk of flash flooding across the majority of the area. Training storms will also help to enhance the flood risk today. A Flood Watch has been issued for much of WV, northeast KY, southeast OH, and southwest VA from this afternoon through tonight. A few storms could also be capable of producing wind damage in downbursts this afternoon and evening; therefore, a marginal risk of severe weather covers the entire forecast area. Portions of the lowlands are once again expected to fell very hot, with apparent temperatures rising into the upper 90s. Like yesterday, the heat risk may be somewhat tempered by precipitation. && .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... As of 350 AM Thursday... Daily chances of rain and thunderstorms persist as a front remains in the vicinity of the middle Ohio Valley and Central Appalachians through the end of the week. Given the already wet conditions present across the area, additional rounds of locally heavy rain will do little to alleviate flood concerns; therefore, marginal to slight excessive rainfall risks cover the entirety of the forecast area late this week. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... As of 350 AM Thursday... Unsettled weather continues as a system passes to the north and pulls another front down into the forecast area early next week. Around mid week, the front slowly lifts north as a ridge builds in from the southwest. However, shortwaves riding around the periphery of the ridge should sustain precipitation chances through the end of the long term period. && .AVIATION /10Z THURSDAY THROUGH MONDAY/... As of 555 AM Thursday... Showers and thunderstorms will increase in coverage during the day, then showers remain possible as a front sinks down into the area tonight. While mainly VFR conditions should continue outside of storms, MVFR to IFR will be possible within heavier rain and storms. Light to moderate west to southwest winds are expected through the day, with gusts into the teens possible this afternoon. Stronger, variable gusts are possible storms. Winds should then weaken overnight. Patchy post-rain fog/mist could be possible tonight, though extent will depend on lingering cloud cover and precipitation. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 12Z FRIDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Timing, locations and intensity of showers and thunderstorms could vary from forecast. Overnight fog formation is not entirely out of the question tonight.
