000 FXUS61 KRLX 221032 AFDRLX Area Forecast Discussion National Weather Service Charleston WV 632 AM EDT Thu Jun 22 2017 .SYNOPSIS... Tropical moisture to bring heavy showers/thunderstorms for the end of the work week into early Saturday. Cooler Sunday through Tuesday, with upper level disturbances possibly providing a few light showers. && .NEAR TERM /THROUGH TONIGHT/...
-- Changed Discussion --
As of 630 AM Thursday... Bumped up pops in scattered range for CKB to EKN for another hour or two, otherwise no other changes made at this time. As of 140 AM Thursday... Kept the low pops in across far north with isolated showers through dawn in close proximity to a warm front. This boundary will retreat off to the north later this morning. Attention quickly turns to what will be the remnants of Cindy. Models continue to be in good agreement on a piece of energy breaking off from the circulation and advancing northeast into the area late afternoon. There may be a few storms in advance of the main area of rain. Despite the surge in pwats, this feature will be progressive this evening, such that flooding concerns are low tonight. QPF amounts of .50 to .75 inches will be common. Tried to show a break late tonight across much of the area, before the next slug of moisture works in from the west at dawn, affecting mainly southeast Ohio, northeast KY, and western WV.

&& .SHORT TERM /FRIDAY THROUGH SATURDAY/... As of 240 AM Thursday... Tropical moisture remains over the region on Friday, with a cold front and the remaining circulation of Cindy moving through Friday night into early Saturday. Models are in decent agreement with the general pattern, although some small timing differences continue. The big differences between models are still in the location of the heavier precipitation bands. Models generally struggle in tropical systems with this, so not a big surprise. The problem however is where to post a flood watch. Confident that one will be needed, but not confident on where. && .LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/... As of 240 AM Thursday... Upper level trough will provide unseasonably mild weather with low humidity through this period. Models have several upper level disturbances moving through the trough, but vary on the strength and timing. Some light showers are possible with these disturbances. && .AVIATION /12Z THURSDAY THROUGH MONDAY/...

An upper disturbance will move north through the area late this afternoon and evening, with showers and a few thunderstorms developing. Brief periods of IFR vsby is possible as this works thru, with an overall lowering of cigs into MVFR. Thunder was kept out of the TAFs for this evening due to low chances.
