.NEAR TERM /THROUGH WEDNESDAY/...
-- Changed Discussion --
As of 545 PM Tuesday...

Showers and thunderstorms continue across the region in advance
of/along a surface cold front that is beginning to slowly
progress through the northwest portion of the forecast area
INVOF the Ohio River. Extensive cloud cover across the area has
largely muted the severe threat, with any convective activity at
this point primarily limited to Charleston south/east. Gusty
winds are possible with thunderstorms across the south over the
next hour or two, but not anticipating anything of the severe variety.

The bigger story has been the heavy rain across portions of the
area, with 1-3"+ from the Charleston metro west into portions
of northeast Kentucky and far southern Ohio. This has resulted
in flash flooding across the aforementioned area. The chance for
high water issues further south/east remains, but should be
more isolated given a slightly faster progression of activity
now. Showers/storms will gradually become more confined to the
higher terrain throughout the evening, with the chance for
showers lingering there through much of the night. Minor tweaks
to the forecast were made in terms of updated PoPs, decreased
chances for thunder across northern portions of the CWA, along
with the mention of heavy rain into the forecast throughout the
evening. The rest of the forecast remains on track.

As of 215 PM Tuesday...

Key Points:
* Cold front crosses later today into tonight.
* Heavy rain could lead to localized flooding.

Showers and scattered thunderstorms will continue to sprout up
across the area as a cold front slowly approaches from the west this
morning. Activity then continues as the front slides towards the
Ohio River later today and then continues east across the area
tonight.

Around 1.75 to 2 inches of precipitable water should continue to
support moderate to heavy rain showers ahead of and along the front.
Excessive rainfall could prompt some localized flooding,
particularly in areas that were impacted by heavy rain earlier
today. Some strong storms could also develop in the warm, moist, and
unstable environment present this afternoon and evening, with
potential for isolated severe storms to produce locally damaging
winds.

Showers and storms taper off behind the front tonight, then high
pressure begins to creep in from the southwest and allows drier
conditions to return to the majority of the area on Wednesday. That
being said, residual moisture could sustain a few showers along the
mountains.

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/...
As of 215 PM Tuesday...

Key Point:
* High pressure brings drier conditions for the second half of the
  work week.

While a weak shortwave may pass overhead, surface high pressure is
expected to support drier conditions Wednesday night into Thursday
morning. An upper ridge then starts to expand east across the area
while high pressure remains present at the surface and allows
relatively benign weather to persist through the end of the work
week. Temperatures will steadily increase beneath the building
ridge, with hot conditions taking hold just in time for the
Independence Day holiday.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
As of 215 PM Tuesday...

Key Points:
* Hot and humid over the weekend.
* Becoming more active again next week.

Expect hot and increasingly humid conditions this weekend, with
chances of precipitation returning as the upper ridge begins to
relinquish control next week. Thereafter, the weather pattern
remains more active as a front slowly approaches from the
northwest while another system travels up the Atlantic Coast
during the new work week.

While precipitation chances have been introduced as early as
Sunday afternoon, model solutions differ with respect to the
timing of the front and breakdown of the ridge. More robust
ridging could sustain drier conditions through the end of the
long term forecast period.

.AVIATION /21Z TUESDAY THROUGH SUNDAY/...
-- Changed Discussion --
As of 200 PM Tuesday...

MVFR to IFR ceilings and periodic visibility restrictions remain
possible in heavy rain, scattered thunderstorms, and low clouds
ahead of a cold front. This front will slowly cross the area
later today, then exit to the east overnight. Brief improvement
may be possible as precipitation tapers off behind the front,
then conditions are likely to deteriorate to IFR or worse in fog
and low stratus overnight. Area wide VFR returns once any fog
dissipates Wednesday morning.

Mainly light and variable winds are expected through the
TAF period, though locally strong gusts may occur in storms this
afternoon and evening.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z WEDNESDAY...
