AREA FORECAST DISCUSSION
National Weather Service Charleston WV
536 AM EDT Thu Jul 10 2025
.SYNOPSIS...
Daily chances for mainly diurnally driven showers and
thunderstorms continue as a warm and moist airmass remains in
place.
&&
.NEAR TERM /THROUGH TONIGHT/...
As of 535 AM Thursday...
Fog coverage has remained patchy enough to forgo a special
weather statement this morning.
As of 200 AM Thursday...
Mid-level cloud cover may assist in impeding formation of
widespread fog this morning, but at least patchy instances are
expected. Think any coverage will be too limited to warrant a
special weather statement for ths morning commute, but will
continue to monitor trends.
Ascent associated with the right entrance region of a H250 jet
stream that extends from northern West Virginia to the Canadian
Maritimes this morning will continue to yield elevated showers and
perhaps an isolated rumble of thunder through late morning. This
ascent should slowly creep southeast out of the forecast area by
this afternoon. This should leave the northwestern half of the
forecast area in weakly convergent upper level flow, while the
southeast half remains more or less neutral. Columnar moisture will
be a little less than in preceding days with PWAT values generally
1.5 to 1.8 inches across the region but warm cloud depths remain
rather deep, 10kft+. In the absence of synoptic forcing, convection
will be primarily diurnally driven with isolated to low end
scattered coverage this afternoon. The best instability is progged
to be across the Middle Ohio Valley where PWATs are slightly higher,
but this will be in the aforementioned weakly convergent flow aloft
which may serve to somewhat suppress convection. Inversely, the
mountains are expected to less unstable, but with parcels not
impeded by convergent flow aloft. Overall, think this largely
balances out coverage wise. Flow through the column will be
substantially weaker than yesterday with deep layer shear around 10-
15KTs, so not expecting much in way of updraft organization. The
main threats with any convection that develops will be locally heavy
downpours (potentially over locally compromised soils) and locally
gusty winds with any core collapses/wet microbursts.
Activity should quickly settle down this evening with the loss of
surface heating with a dry overnight. Clearing skies, light winds,
and wet ground conditions should set the stage for a good fog night,
likely more widespread than just in the typical valleys.
&&
.SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/...
As of 200 AM Thursday...
Weak ridging aloft is expected to be in place Friday through
Saturday with PWATs sitting a little closer to mean to 75th
percentile values based on proximity soundings. Subsidence aloft
does not appear strong enough to completely suppress diurnally driven
convection, but coverage should be rather limited. Deep layer shear
remains fairly weak, so not expecting much of a threat from this
activity outside of some locally gusty winds or perhaps some storm
scale interaction. A weak shortwave undercutting the ridge Saturday
evening may offer a little better convective coverage than Friday.
Afternoon highs through the period remain a little warmer than
normal for this time of the year with values across the lowlands
generally in the upper 80s to lower 90s. Heat indices are expected
to remain below advisory criteria with afternoon mixed dew point
values generally in the upper 60s to lower 70s.
&&
.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
As of 200 AM Thursday...
Weak ridging starts to break down on Sunday as troughing approaches
the Upper Great Lakes. This should yield a little better diurnally
driven convective coverage on Sunday. Models to differ slightly with
the timing of this troughing, and it is conceivable, although at
this point not likely that it arrives early enough Sunday evening to
support some better organized convection as deep layer shear
increases to around 35KTs across our north.
In the wake of this feature, we should see a brief return to a drier
column for the balance of the forecast before Gulf influenced
moisture once again invades the region toward mid to late in the
week.
&&
.AVIATION /10Z THURSDAY THROUGH MONDAY/...
As of 535 AM Thursday...
Upper level clouds clearing out across SE OH and pockets
elsewhere has allowed patchy fog and/or low stratus to develop
this morning. Should see this, along with residual low level
moisture lift into a ~009-015 stratocumulus deck this morning
transitioning into cumulus/moderate cumulus/towering cumulus by
early this afternoon. Isolated thunderstorms will be possible
after 17Z, but confidence of thunder at any given field is too
low for anything other than VCTS in the TAFs at this time. If a
thunderstorm does make it over a field, it will be capable of
producing some locally heavy rain that may yield IFR conditions.
Storms will also be fairly slow moving, with a single cell
taking 30 to 60 minutes to cross an aerodrome.
Any convective activity settles down with loss of heating this
evening. With light winds, mostly clear skies and plenty of residual
moisture, widespread fog, some dense, is expected to develop after
06Z.
Winds generally light except gusty and erratic near convection.
FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 12Z FRIDAY...
FORECAST CONFIDENCE: Medium.
ALTERNATE SCENARIOS: Timing of improvement to VFR this morning
may vary. Isolated convection this afternoon may affect any
given terminal.
