128 FXUS61 KRLX 090521 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 121 AM EDT Sun Jun 9 2024 .SYNOPSIS... Weak cold front passes overhead today, providing a chance of showers and afternoon thunderstorms. Mainly dry through the work week with building heat. && .NEAR TERM /THROUGH TONIGHT/... As of 120 AM Sunday... A moisture starved cold front is set to pass over the area from north to south today. Radar trends at the time of writing depict rain draped along the front from northern Ohio into upstate New York, which will gradually shift southward through the course of the early morning hours. Showers should then arrive to the northern fringes of our forecast area closer to daybreak, continuing a southward progression later this morning into the afternoon. Thunderstorm development along the front becomes more likely during the heat of the afternoon, which may come at a point where the front will have almost already completed its full passage through our southern forecast zones. Maintained a mention of thunder for the coalfield areas this afternoon, then tapering back down to only lingering showers by the evening. Upper level jet support drifts out the area tonight in tandem with the surface cold front tracking further south into the Carolinas and Mississippi Valley. Dry weather then settles back over the Central Appalachians for the end of the period and into the start of the new week. && .SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/... As of 203 PM Saturday... A shortwave moving across the northeast may provide some light/brief shower activity mainly across the north and east on Monday, but overall drier and cooler weather will take hold with surface high pressure building in, and northwesterly flow aloft taking hold. Continued cool and dry on Tuesday as northerly flow remains in place. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... As of 1150 AM Saturday... Increasingly warm and humid conditions will take hold for mid to late week as upper ridge takes hold across the area. Ridge will break down towards the end of the period, with unsettled weather returning once again as a cold front approaches the area. && .AVIATION /05Z SUNDAY THROUGH THURSDAY/... As of 120 AM Sunday... Scattered to broken clouds continue to overtake the area early this morning ahead of a frontal passage progged near daybreak. MVFR ceilings will be draped along the front, with some pockets of IFR possible along the mountains. Should see ceilings recover quickly into the afternoon as the front continues a southward progression. A few showers will also accompany the front, passing over our terminals during the morning into early afternoon from north to south. Thunderstorm development along the front will be more likely to occur after the front has completed its passage through all TAF sites. Dry weather returns this evening into the overnight hours. Light surface winds will gradually veer out of the northwest today as the cold front presses overhead. May see a brief wind of LLWS at EKN around daybreak this morning with a passing low level jet, but otherwise post-frontal winds may impose breezier conditions for the afternoon and evening. Surface flow tapers down late this evening. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 06Z MONDAY... FORECAST CONFIDENCE: High, becoming Medium with FROPA.
