790 FXUS61 KRLX 061649 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 1249 PM EDT Fri Jun 6 2025 .SYNOPSIS... Scattered to numerous showers and thunderstorms today, some may contain damaging wind and large hail. Heavy rain will be possible with any convection today and tonight. Active weather persists into the weekend as the front stalls over the area. && .NEAR TERM /THROUGH TONIGHT/... As of 1025 AM Friday... Forecast remains on track this morning, necessitating no updates ahead of the afternoon package. A few showers have tracked through the area this morning, but the better chance for activity will arrive for the afternoon and evening. As of 300 AM Friday... Key Points: * Marginal threat for severe hail and winds with thunderstorms this afternoon. * Slow moving, efficient convection may yield high water issues, especially tonight into Saturday morning Weak surface low pressure riding along a stalled frontal zone across the Middle Ohio Valley coupled with weak H850 mass convergence at this hour continues to support elevated showers and thunderstorms. Expect these to continue to progress to the east following a more or less west to east oriented ribbon of instability through this morning, likely becoming surface based across northern WV early this afternoon with additional diurnally forced convection blossoming as surface parcels become uncapped. We do have quite a range of model solutions regarding phasing of northern/southern stream jet energy during the day today with WRF camp generally the aggressive and RAP least aggressive in phasing early and spreading ascent across the area in time to enhanced the aforementioned showers and thunderstorms. The later solutions would yield higher instability co- located with stronger deep layer shear and a higher potential for damaging wind gusts and perhaps some marginally severe hail (although wet bulb zero values near 12kft likely limit this) this afternoon. The faster solutions would yield a period of subsidence or at least the lack of broad ascent heading into peak heating, especially across our west where we could remain storm free during the late afternoon. The slower solutions would yield weaker flow through the column resulting in slower storm motions and more narrow CAPE profiles favorable for efficient rainfall production yielding a bit better chances for some water issues, although heavier rainfall footprints during the daylight hours are not expected to significantly overlap the heavier rainfall footprints from last night. Otherwise, for areas that don`t see convection this morning, except highs generally in the upper 70s to lower 80s. The potentially more significant water concerns look to arrive overnight as slow moving frontal boundary lays out west to east across area with at least some models putting it nearly directly over a heavier rainfall footprint from last night across the Mountain Lakes. Significant training appears possible along this boundary during the late overnight into Saturday morning, but given the model spread don`t have a ton of confidence in placement. Plan to take a hard look at the 06Z suite as it comes in for a potential flood watch before I leave this morning, but otherwise will defer to the day shift for any highlights. && .SHORT TERM /SATURDAY THROUGH MONDAY NIGHT/... As of 1246 PM Friday... Widespread showers and thunderstorms are expected Sunday as a warm front lifts north through the region and a 500-mb vort. max crosses from the west. PWATs will be slightly lower Sunday, ranging from 1.25-1.50" across the region. However, slow-moving downpours are still possible. In addition, saturated soils from recent heavy rainfall can lead to quicker instances of localized flooding. The areas at greatest risk of flash flooding would be urban areas and in any training cells. 25-30 kts of 0-6km shear and 800-1,000 J/kg of MLCAPE can lead to a few strong to severe thunderstorms during the afternoon. The main threats appear to be damaging winds and hail. A marginal risk of severe weather and excessive rainfall are both outlooked for Sunday. A cold front will still be west of the County Warning Area Monday, so showers and thunderstorms will remain possible once again, especially during the afternoon. Building afternoon instability and modest shear will create additional chances for damaging wind gusts and large hail. Temperatures will reach the upper 70s Sunday with widespread clouds and convection. Monday will be a bit warmer with our region located in the warm sector and more breaks of sunshine expected. High temperatures will be in the lower 80s Monday. && .LONG TERM /TUESDAY THROUGH THURSDAY/... As of 1246 PM Friday... A cold front will cross through the region midday Tuesday, leaving dry and quiet weather in its wake. Temperatures in the upper 70s to lower 80s Tuesday and Wednesday will rise to the middle and upper 80s by Thursday and Friday as a large upper-level ridge moves over the eastern portion of the country. The next chance of widespread rain will be towards the end of the week. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/... As of 1245 PM Friday... Bubbling afternoon cumulus field will impose brief restrictions in the form of passing showers and storms. Tempo groups will be present with this issuance alongside SHRA/VCTS through this evening as a cold front drapes itself in close quarters to the forecast area. Activity today will be capable of producing damaging wind gusts, hail, and heavy downpours. As the front drapes itself over the Central Appalachians overnight, additional bursts of rain and lowered ceilings/visibilities settle into our airfield. By Saturday morning, all stations are expected to fall under IFR thresholds during the predawn hours, then gradually rising as daytime mixing transpires. Shower and storm coverage will become more isolated in nature as the front slips further to the south on Saturday, but is anticipated to wobble near the area through the weekend, maintaining an active weather pattern for the next several days. Winds will remain generally light below 10kts through the period, but could locally grow stronger under showers and storms. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z SATURDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Convective coverage will vary, will need to address with additional TEMPOs through the day.
