908 FXUS61 KRLX 091802 AFDRLX AREA FORECAST DISCUSSION National Weather Service Charleston WV 202 PM EDT Sun Jun 9 2024 .SYNOPSIS... Weak cold front passes through today, providing a chance of showers and isolated afternoon thunderstorms. Mainly dry through the work week with building heat. && .NEAR TERM /THROUGH MONDAY/... As of 120 PM Sunday... A cold front, rather weak in strength, is currently traversing our forecast area this afternoon. Scattered low clouds and showers will continue to spawn ahead of the front this afternoon as it passes through. There is the slight chance for an isolated thunderstorm or two across portions of the mountains with the frontal passage during peak heating this afternoon. Behind the front, flow shifts more northwesterly and clouds will gradually lift and scatter, however a few low-level cloud streets will continue to filter through at times with the breezy northwesterly flow. Outside of the higher elevations, winds are forecasted to slack off tonight becoming light or calm for many locations. Temperatures this afternoon will be a few degrees below normal with upper 70s to around 80 degrees expected for the lowlands, while the mountains will stay in the 60s to the middle 70s. Lows tonight will drop back in the 50s with a few locations in the higher terrain seeing temperatures in the upper 40s. Drier weather and some clearing moves in Monday morning behind a reinforcing, dry cold front. Light and calm winds will pick back up by Monday afternoon becoming breezy at times. Temperatures will be below normal, but still comfortable. The lowlands will range anywhere from the upper 60s to the mid 70s, while the mountains will observe anywhere from the upper 50s to the lower 70s. && .SHORT TERM /MONDAY NIGHT THROUGH WEDNESDAY NIGHT/... As of 220 AM Sunday... Northwesterly flow continues aloft through Tuesday yielding temperatures a little cooler than normal for this time of the year for Monday and Tuesday. Couldn`t completely rule out a stray shower on Monday as a shortwave transits the base of the long wave trough overhead, but most locations should remain dry. Heights begin to rise Tuesday as low amplitude ridging begins to move into the Lower Ohio Valley with surface temperatures edging up around a degree or two above Monday`s values. With a still rather dry airmass and no forcing overhead, Tuesday should be a dry day. && .LONG TERM /THURSDAY THROUGH SATURDAY/... As of 1202 PM Sunday... Increasingly warm and humid conditions will take hold for mid to late week as southerly flow increases across the area. Thursday and Friday both will see temperatures in the 90s across much of the lowlands, with an increase in chances for showers and storms on Friday with the approach of a front. Although a bit far out, cannot completely rule out an isolated strong to severe storm during this period, with a wind damage threat. Overall drier, but still above normal temperatures, look to take hold once again for next weekend. && .AVIATION /17Z SUNDAY THROUGH THURSDAY/... As of 150 PM Sunday... Improvement to VFR will commence for the ~18Z cycle as a cold front passes. MVFR cigs will improve to VFR this afternoon, but a few models show some post-frontal MVFR cigs filtering through this afternoon. For the mountains, this means showers and the slight chance for an isolated thunderstorm or two ahead of the front this afternoon; allowed VCTS at BKW to cover this. Winds will be breezy, maybe gusty at times across the mountains, this afternoon with and behind the FROPA as flow becomes more NW`rly. Winds will slack off and go light to calm for many locations overnight, except for the higher ridgetops of the mountains. Short-range model consensus predicts MVFR cloud deck across the northern mountains again tonight, but this should not affect any terminals. Otherwise, drier weather moves in later tonight/early tomorrow as a secondary dry cold front arrives. VFR conditions look to be in the cards tomorrow. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z MONDAY... FORECAST CONFIDENCE: Medium. ALTERNATE SCENARIOS: Timing and intensity of showers and thunderstorms with the cold front today could vary. Timing for ceiling improvement to VFR could vary from forecast.
