NORTHWESTERN RANDOLPH...SOUTHEASTERN LEWIS...EAST CENTRAL BRAXTON...
UPSHUR AND NORTHEASTERN WEBSTER COUNTIES...

At 356 PM EDT, Doppler radar indicated thunderstorms producing heavy
rain across the warned area. Up to two inches of rain have already
fallen. Flash flooding remains possible.

Some locations that will experience flooding include...
Rock Cave, Holly River State, Womelsdorf (Coalton), Alexander, Eden,
Helvetia, Pickens, Cleveland, Alton, Hacker Valley, Ellamore, Kanawha
Head, Ireland, Tallmansville, Centralia and French Creek.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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

In hilly terrain there are hundreds of low water crossings which are
potentially dangerous in heavy rain. Do not attempt to cross flooded
roads. Find an alternate route.

Flooding is occurring or is imminent. It is important to know where
you are relative to streams, rivers, or creeks which can become
killers in heavy rains. Campers and hikers should avoid streams or
creeks.

Please report Severe Weather to the National Weather Service by
calling toll free, 800 401 9535, when you can do so safely.

You may also report severe weather by posting your report to the

AREA FORECAST DISCUSSION
National Weather Service Charleston WV
229 PM EDT Thu Jul 11 2019

.SYNOPSIS...
Cold front moves through on later today with strong storms.
Another high pressure builds for the beginning of the weekend.
Unsettled weather returns next week.

&&

.NEAR TERM /THROUGH FRIDAY/...
As of 940 AM Thursday...

Performed a refresh on PoPs this morning to better correlate
with radar and satellite trends. Do expect to be somewhat
chasing PoPs today, as synoptic forcing lends to scattered
convection along subtle mesoscale waves in the uncapped
environment. At this hour, a broken prefrontal wave crosses the
64/79 corridors with another wave forming behind it over
southern Ohio. Will have to carefully monitor these storm
clusters as they intensify this afternoon, and as they modify
the environment the eventual cold front enters this evening.

As of 530 AM Thursday...

A cold front will approach from the west tonight. Ahead of the
front, expect an increase in clouds and showers mainly across
the southern half of the area this morning. Shower and storm
activity could intensity this afternoon aided by afternoon heat
and CAPE and some deep layered shear. In fact, there is a slight
risk for severe thunderstorms over portions of southeast OH and
northern half of WV through this evening. The main threat will
be damaging winds. PWATs around 2.25 inches suggest heavy
downpours could result in very heavy instantaneous pcpn rates
leading to flash flooding.

The actual cold front arrives along the OH River by 06Z tonight,
to promote additional showers or storms over the area. The front
moves east late tonight, exiting the eastern mountains by early
Friday morning.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY NIGHT/...
As of 225 PM Thursday...

Drier air, at least off the surface, will continue to advect
into the area Friday night with PWATs dropping below an inch.
Some dense river valley fog looks to develop overnight as lows
settle down below readings from recent days values.

Saturday looks to mainly sunny with just enough mixing to bring
down drier air aloft for dewpoints to drop into the lower to mid
60s. High temperatures look to be very close to normal.

A warm front develops across portions of the OH Valley on Sunday
which will provide for a change of diurnally driven convection,
in addition to an uptick in humidity/temperature.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
As of 225 PM Thursday...

Upper level riding tries to build in early next week with
attention turning to where the remnants of Barry track. It may
take until Wednesday or Thursday to see the effects from this
system.

&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
As of 200 PM Thursday...

VFR prevails at all sites this afternoon with IFR or worse
conditions likely in waves of heavy-raining thunderstorms. Winds
prevail from the SW today, turning gusty and variable in storms.
In general storms will produce variable gusts in the 20-30 kt
range, although the strongest storms will be capable of
producing 40+ kt winds. High moisture content is leading to very
heavy downpours with brief drops in visibility, commonly to IFR, to
LIFR in heaviest storms. Larger clusters of shower activity are
capable of bringing ceilings down to MVFR as well.

Most sites are seeing impacts at this time, spare for PKB, who
is enjoying a break in the action. This break is likely area-
wide late this afternoon, before another wave of storms comes in
later this evening. Though, the weakly capped environment will
still be conducive for isolated to scattered showers. After the
cold front crosses tonight from W to E, winds shift to
northwesterly. Tomorrow morning during the pre- dawn hours, a
low stratus deck is likely to form near and south of the slow-
moving front. GLAMP guidance suggest reduced ceilings at all
sites, however do think it'll be a bit tougher to attain at PKB
and HTS. At any rate expect stratus deck to lift and scatter
through the morning. Low confidence exists in this portion of
the forecast with widely varying model solutions. Low level flow
ought to stave off fog development, though if these should
calm, quick VSBY degradations are likely overnight with high
humidity.

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

FORECAST CONFIDENCE: Medium/high today, low tonight.

ALTERNATE SCENARIOS: Timing of convection may vary; timing and
occurrence of LL stratus may vary; patchy fog is possible though
unlikely.
