National Weather Service Charleston WV
929 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/...
As of 925 AM Thursday...

No changes this morning.

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 /14Z THURSDAY THROUGH MONDAY/...
12Z Thursday through 12Z Friday...

As of 630 AM Thursday...

Clouds will increase and lower on today, but generally remain
VFR. 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.
