000 FXUS61 KRLX 212342 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 742 PM EDT Sat Apr 21 2018 .SYNOPSIS... High pressure through the rest of this weekend. Upper low Monday through Wednesday. Weak high pressure for the end of the week. && .NEAR TERM /THROUGH SUNDAY/... As of 600 PM Saturday... Sent a quick update to adjust up hourly temperatures through 00Z. Rest of forecast remains on track. As of 115 PM Saturday... Big bubble no trouble. High pressure will stay in control through Sunday. Some high clouds will start to filter in from the west late this afternoon and overnight tonight. Temperatures tonight won`t be as cold as last night with increasing high clouds. High pressure starts to move eastward during the day tomorrow, look for temperatures to stay on the warm side as winds shift to a more southerly direction. && .SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY NIGHT/... As of 245 PM Saturday... Split flow aloft tracks a closed low into the Tennessee valley and southern and central Appalachians for the beginning of the week, bringing off and on rain through the short term over a couple days period of time. Associated surface low will move across the deep south and up the coast in conjunction with the movement of the upper system. While the surface low should not directly affect our area, it will prevent high pressure from entering the picture until the long term with the next wave aloft enters the Ohio Valley. && .LONG TERM /WEDNESDAY THROUGH SATURDAY/... As of 245 PM Saturday... Weak high pressure is short lived at the onset of the extended forecast as the next upper wave digs into the Great Lakes and Ohio Valley. Operational models are trying to strengthen this feature as of the 12Z runs and close it off, which would lean towards another seasonably cool airmass for next weekend, but will play the modest hand for now. && .AVIATION /00Z SUNDAY THROUGH THURSDAY/... As of 120 PM Saturday... Widespread VFR conditions expected through the period. High pressure remains in control as it moves east. Upper level clouds will increase in coverage overnight. Winds will be light and variable tonight. A southerly shift to the winds Sunday as the high pressure moves off to the east. FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z MONDAY... Timing of increasing clouds may vary overnight and early Sunday morning. FORECAST CONFIDENCE: High. ALTERNATE SCENARIOS: None.
