000 FXUS61 KRLX 190706 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 306 AM EDT Thu Apr 19 2018 .SYNOPSIS... Upper level low with rain showers transitioning to upslope snow showers and lingering into early Friday. && .NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
As of 305 AM Thursday... Surface low has transitioned across the forecast area, with the cold front also moving east of the forecast area. Line of post frontal showers gradually shifting east, with some gusty winds. Expect a brief break across the middle Ohio River Valley before have POPs on the increase as an upper level low moves into the region. Keep lingering showers across the eastern mountains between the two features. Cold air starting to surge in behind the front, and think mid level temperatures will be cold enough to start supporting a transition to snow across the mountains by about 12Z. Could even get some flakes across the lower elevations as the precipitation tapers off... however moisture exits pretty quickly so not expecting much more than some flurries into this afternoon across the lowlands. Generally have an inch or two of snow accumulation across the highest ridges. today into tonight. Behind the cold front, expect gusty winds to linger today. Strongest winds will be across the higher ridges, where a wind advisory is already in effect. Today will be rather chilly...especially across the eastern mountains where steady to even slowly falling temperatures are expected. Farther west, we should see some warming this afternoon but temps still expected to be 15 degrees or more below normal. Tonight should bring temperatures near or below freezing and have issued a freeze warning for the area where the growing season has been deemed active.

&& .SHORT TERM /FRIDAY THROUGH SUNDAY NIGHT/... As of 230 AM Thursday... Precipitation should have generally tapered off across the higher terrain by the start of the period. High pressure with dry conditions/low RH and light surface winds during the remainder of the period. Could be a need for a frost advisory at least Saturday morning under these conditions. Gradually warming as weekend progresses with upper ridging shifting east. && .LONG TERM /MONDAY THROUGH WEDNESDAY/... As of 235 AM Thursday... Active weather returns for the period. A low pressure system in the southern stream will spread moisture into the area for Monday and Tuesday. Precipitation should be in the form of rain during the period. Another cold front moves through the area by mid week, with additional rounds of showers. && .AVIATION /07Z THURSDAY THROUGH MONDAY/... As of 130 AM Thursday... A cold front has passed east of the forecast area, with an area of showers lingering behind it. Mostly VFR right now, but should see ceilings gradually dropping into MVFR as colder air moves in below an upper level low. This will also provide lingering rain or snow showers. Could get some brief reductions in visibility in these showers but hard to time any of this out. Winds will be gusty -- generally out of the west and northwest today into tonight.
