...FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 3 AM EDT EARLY THIS 
MORNING FOR NORTHERN ROANE AND FAR SOUTHERN WIRT COUNTIES...

At 119 AM EDT, Doppler radar indicated thunderstorms had produced 
heavy rain across the warned area. Between 2.5 and 3.5 inches of 
rain have fallen. Flooding impacts will continue, but no additional 
rainfall is expected. Flash flooding is ongoing or expected to begin 
shortly.

HAZARD...Flash flooding caused by thunderstorms.

SOURCE...Radar.

IMPACT...Flash flooding of small creeks and streams, urban areas,
         highways, streets and underpasses as well as other poor
         drainage and low-lying areas.

Some locations that will experience flash flooding include...
  Spencer and Reedy.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood 
deaths occur in vehicles.

Be especially cautious at night when it is harder to recognize the

AREA FORECAST DISCUSSION
National Weather Service Charleston WV
1037 PM EDT Tue Jul 23 2024

.SYNOPSIS...
Chances for showers and thunderstorms each afternoon courtesy
of a stationary boundary lingering overhead. Slow moving storms
may yield very isolated high water issues. Drier this weekend.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
As of 1035 PM Tuesday...

The forecast remains on track.

As of 720 PM Tuesday...

There were no changes needed to the forecast as it remains on
track.

As of 120 PM Tuesday...

Two separate areas of enhanced lift, the first associated with a
departing 90KT jet streak over northern WV at this hour and the
second associated with an approaching 90KT jet streak over the
Middle Mississippi Valley at this hour will affect the region this
afternoon and overnight.

This former will enhance diurnal convection primarily across the
Southern Coalfields into the eastern mountains this afternoon with
highly efficient rainfall processes yielding rainfall rates upwards
of 4"/hr. Storm motions out of the southwest around 25 mph will keep
individual cells from dwelling over any given spot for too long, but
at least some training potential may be able to eventually
accumulate some very localized water issues with repetitive storms.
Deep layer shear of around 30-35KTs will support updraft
organization, but any significant threat would likely be confined to
very localized wind damage with cores falling out of storms. This
activity should settle down late this afternoon into this evening as
weak subsidence arrives coincident with loss of heating.

The latter area of ascent should yield renewed overnight activity
approaching from the west with some additional threat of locally
heavy rain. With boundary layer dew point spreads closer, should see
less risk of any locally gusty winds with this activity.

As activity tapers off from west to east toward dawn, any locations,
especially valley locations that see measurable rain may fog up into
daybreak.

In the wake of activity before daybreak should see a lull in
subsidence during the morning hours on Wednesday with diurnally
enhanced convection popping across the south. An additional area of
enhanced convection is expected to approach our northwestern
counties toward the end of the near term period as a cold front
slowly approaches the Middle Ohio Valley.

Outside of the Southern Coalfields and portions of the eastern
mountains, little if any significant precipitation has fallen over
the last 3 days and these areas should largely be able to handle
rainfall outside of extremely localized issues in sustained high
rates. Farther south and east, swaths of higher rain totals over the
last few days will yield a little easier time in converting heavy
rainfall into pure runoff - here any localized issues could be a
little more common, but still too isolated to support a Flash Flood
Watch.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
As of 200 PM Tuesday...

Frontal bndry situated well north of the area across the southern
Great Lakes Wednesday night. This front will slowly push south and
east into Thursday with a round of scattered to numerous showers and
thunderstorms. Highest POPs are expected during the afternoon hours
with locally heavy rain the main concern as PWAT values remain
around 1.75". Not expecting any significant hydro concerns given the
ongoing drought, but typical flood prone areas and any locales that
receive multiple rounds of storms could see some isolated flood
concerns,m, especially across the southern coalfields.

Front should pass through later Thursday evening into Friday
morning, with much of the area dry. Some lingering post frontal
showers and an isolated storm or two could hold onto the southern
coalfields and eastern mountains, but POPs remain low.

Some patchy fog is possible in river valleys Wednesday night and
possibly again Thursday night dependent on location of the frontal
bndry and how much dry air works into the region. Best chance for
any fog development would be across the southern coalfields and
mountains.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
As of 140 PM Tuesday...

Frontal bndry expected south of the area as of Friday morning with
lingering isolated/scattered showers and storms across the southern
third of the CWA. Even less shower/storm activity expected into the
weekend as drier air filters in with mid level ridging building
across the region.

Increasing S/SW flow by early and middle next week will
increase moisture/TDs as mid level ridging breaks down. This general
weakness aloft, with the possibility of disturbances passing through
the region, will gradually increase POPs into early next week. A
gradual warming trend is also expected with highs in the upper 80s
to lower 90s in the lowlands. Increasing humidity will also lead to
some muggy afternoons.

&&

.AVIATION /03Z WEDNESDAY THROUGH SUNDAY/...
As of 730 PM Tuesday...

Tonights pattern will allow for shower and storm activity
through midnight, thereafter a lull should occur. There will
still be chances for an isolated shower overnight at some
sites, such as EKN and BKW. Valley fog should be prevalent but
how much will depend on how spread low to mid clouds are. Some
will form at sites that previously had rainfall and some valley
fog may spill into a few sites such as PKB and CRW but thinking
restrictions will be held to MVFR, maybe some lower at times.
Not looking at widespread fog development due to possible cloud
coverage. Most sites should have some reprieve from activity
until the afternoon when diurnal convection will fire up once
again.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z THURSDAY...

FORECAST CONFIDENCE: Medium.

ALTERNATE SCENARIOS: Fog may not form at terminals with little
precipitation and lingering clouds overnight.
