000 FXUS61 KRLX 210705 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 305 AM EDT Sat Apr 21 2018 .SYNOPSIS...
-- Changed Discussion --
High pressure through the weekend. Next system arrives Monday afternoon.
-- End Changed Discussion --
&& .NEAR TERM /THROUGH TONIGHT/... As of 1245 AM Saturday... A high pressure system will control the weather for today and tonight. However, the right rear of an upper level jet will provide some high clouds. Looking at soundings, expect that dry air will mix to the ground during the afternoon hours. Therefore, went on the lower side of dewpoints. && .SHORT TERM /SUNDAY THROUGH TUESDAY NIGHT/...
-- Changed Discussion --
As of 255 AM Saturday... Still looking at a warm day Sunday courtesy of light low level southeast flow developing. I do expect quite a bit of high clouds around so did not stray from warmest guidance. An upper level system will pivot through early next week with scattered showers late afternoon Monday across southern zones...and overspreading the remainder of the area Monday night. It still appears the heaviest rains will remain east of the forecast area, except along the eastern slopes where a decent easterly flow will maximize amounts. Despite the unsettled conditions, it will remain mild.

&& .LONG TERM /WEDNESDAY THROUGH FRIDAY/...
-- Changed Discussion --
As of 300 AM Saturday... Multiple upper level impulses embedded within the amplifying upper trof pivot through the Ohio Valley in the extended. This will keep the threat of showers each day, particularly late Friday.
