Area forecast discussion, Aug 17, 10:01 AM EDT, 2 hours 47 minutes before

Area Forecast Discussion
National Weather Service Charleston WV
1001 AM EDT WED AUG 17 2016

.SYNOPSIS...
Cold front will move through the forecast area today providing
more rain and thunderstorms. Another cold front this weekend.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 10 am Wednesday...Tracking mid to upper level trough moving
through central and eastern KY this morning with associated band
of showers and isolated thunderstorms. Latest satellite imagery
indicate that cloud tops are starting to cool, as trough moving
into an area of more favorable development. So, we could see more
pronounced precipitation development as the trough moves across
this afternoon, especially along the Ohio River counties. Flow is
southwesterly throughout a moist atmospheric column. Temps and
POP forecast on track. Made slight adjustments upward to POP field
based on latest radar and HRRR trends. Overall, these changes do
not change the forecast much. PWAT values across the Ohio Valley
will be up in the 2 inch range for this afternoon. Holding off on
any headlines for widespread water problems this afternoon. But we
could see some isolated water problems, especially in north
central WV where flash flood guidance values lowest later today.

&&

.SHORT TERM /THURSDAY THROUGH FRIDAY NIGHT/...
As of 245 am Wednesday... By Thursday morning the cold front
should be mostly through the region. Have kept some chance PoP in
for Thursday morning and into the afternoon for Southwest Virginia
and in the West Virginia Mountains as orographic accent in the
weak NW flow and their close proximity to the front may enhance
shower activity.

Things look to dry out overnight Thursday...but that will be
short lived as guidance is indicating an increase in moisture
across the region on Friday. Expect to see diurnal showers and
storms develop and maximize in coverage late Friday afternoon and
Friday evening...similar to what we have seen the last few days.
The next short wave looks to edge closer to the region Saturday
morning...but at this time it appears it should not have any
impacts until after the short term period of the forecast.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
As of 230 pm Tuesday...

Models remain in good agreement on a stronger upper level short
wave trough pushing a stronger cold front through the area Sunday.
The front stalled to our south will lift northward on Saturday.
plenty of moisture out ahead of this system will increase the
chances of showers and thunderstorms. Sunday the front pushes
through and exits on Monday. Cooler and drier air works into the
area late Monday night into Tuesday...as high pressure builds in
across the region. Pretty much stuck with a blend of guidance
temps throughout.

&&

.AVIATION /14Z WEDNESDAY THROUGH SUNDAY/...
As of 530 am Wednesday...

VFR/MVFR mix, trended Tafs a little more optimistic for the 09z
update given the atmospheres tendency to go towards low stratus
rather than fog. Cold front passes later today for another round
of tstorms and associated ifr flight cats.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 12Z THURSDAY...

ALTERNATE SCENARIOS: Fog may not develop due to stronger winds
