000 FXUS61 KRLX 301227 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 827 AM EDT TUE AUG 30 2016 .SYNOPSIS... Weak high pressure today. Cold front slides through Wednesday night. Drier and cooler weather to end the week. && .NEAR TERM /THROUGH TONIGHT/... As of 215 AM Tuesday... Weak high pressure over the area today...but some moisture remains in the mountains. Therefore...can not rule out a few afternoon or evening showers or thunderstorms. Will continue with small pops in the mountains. && .SHORT TERM /WEDNESDAY THROUGH FRIDAY/... As of 250 AM Tuesday... Main player for the short term is a cold front which will cross the forecast area Wednesday night. For the day Wednesday, we will be in the transition time period between current high pressure exiting and cold front approaching from the northwest. Models in fairly good agreement with Wednesday being dry across much of the CWA. Do have some low end POPs across the mountains during the afternoon. Also have POPs leaking into far northwest zones late Wednesday afternoon into evening. Showers and storms associated with the cold front will cross Wednesday evening and overnight. Have POPs lingering into Thursday afternoon across the southern WV mountains and southwest VA with 500mb shortwave trough crossing during this time frame...however moisture may already be meager low to support much. Wednesday will be another warm day, however behind the front much of the CWA will struggle to reach 80 on Thursday...with a comfortable night expected Thursday night. && .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... As of 820 AM Tuesday... Used WPC forecast for this part of the package. High pressure will build across the area Friday night...and then remain in control through the remainder of the period. This should result in dry weather...with a warming trend. WPC temperatures looked reasonable and were followed. && .AVIATION /13Z TUESDAY THROUGH SATURDAY/... As of 605 AM Tuesday... After the fog lifts this morning...expect a VFR cumulus field in the mountains and portions of the coal fields...with clear skies elsewhere. A few showers and thunderstorms are possible this afternoon and evening in the mountains. Outside of the precipitation...VFR skies will prevail this evening. Dense river valley fog will again form later Tuesday night. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 12Z WEDNESDAY... FORECAST CONFIDENCE: High.
