AREA FORECAST DISCUSSION

.SYNOPSIS...
Quieter weather returns for Friday and into the weekend outside
of a few afternoon showers/storms along the mountains. Turning
hotter this weekend as high pressure builds surface and aloft.

&&

.NEAR TERM /THROUGH FRIDAY/...
As of 446 PM Thursday...

Went with a blend of the NBM and RAP13 for PoPs this afternoon,
which accented higher probabilities for showers and thunderstorms
across the Tri-State Area and portions of the southern coalfields.
CAMs show most of this activity moving out by sunset with the
exodus of the cold front.

As of 230 PM Thursday...

Satellite and radar trends this afternoon depict a line of
towering cumulus, embedded with a few developing showers, draped
across the I-64 corridor as a cold front sinks southward today.
Steering flow out of the north will encourage these showers, and
any additional showers and storms that develop, to move down
into the coalfields and eventually out of the area altogether by
this evening. The risk for severe weather and flash flooding
will be low with today`s activity.

The frontal boundary is progged to drift down and settle into
the Carolinas overnight and through the end of the forecast
period. Nearby high pressure will promote mostly quiet weather
for the rest of the work week in the wake of the frontal
passage. This will advertise favorable conditions for river
valley fog late tonight into Friday morning, followed by fair
weather cumulus fields for the afternoon timeframe.

Slightly warmer temperatures are anticipated for Friday
afternoon, with highs in the lowlands ranging between the upper
80s to low 90s and around the mid 70s along the mountains.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
As of 230 PM Thursday...

The weekend is anticipated to feature mostly dry weather and
warming temperatures as a strengthening ridge over the heart of
the country begins its multi-day reign over the region. Nearby
high pressure will supply mid to upper level dry air that will
mitigate development of showers and storms across the area, outside
of terrain-induced influences over the mountains that may pop a
few afternoon showers and thunderstorms for both Saturday and
Sunday.

The evolution of the upper ridge will yield building heat each
day in the short term period. Optimal diurnal heating, coupled
with increasing humidity, will produce readings in the lowlands
each afternoon spanning the low to mid 90s, but feeling closer
to 100 degrees or warming in response to increasing dew points.
Relief from the heat is not progged to occur until later in the
long term forecast period.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
As of 230 PM Thursday...

A shift in the weather pattern begins to arise for the new work
week as ripples of shortwave energy skirting around the
northern periphery of the upper ridge drifts down into the
Central Appalachians. This opens the door for increased
potential for showers and storms within the forecast period, but
global consensus remains uncertain on timing and extent of
passing shortwaves in addition to the strength and positioning
of the ridge aloft. A surface cold front is slated to slip down
into the area early next week, which will also encourage better
probabilities for precipitation as it festers over the region in
the midst of tropical activity in the Atlantic disrupting the
boundary`s forward progression.

Other main parameter of note will be the continuing heat wave
aforementioned within the short term period. Daily afternoon
temperatures spanning the mid 90s for many locations in the
Tri-State area will feel closer to the triple digits in response
to higher moisture content and resulting humidity prevailing
over the area. Central guidance hints at the robust ridge
breaking down around midweek, which will aid in alleviating the
oppressive heat.

.AVIATION /21Z THURSDAY THROUGH TUESDAY/...
As of 230 PM Thursday

Shower and storm activity is expected to be lesser in coverage
today in the wake of a cold front slipping southward. At the
time of writing, a few cells were beginning to develop along the
I-64 corridor between HTS and CRW, with anticipated additional
activity drifting down into the southern coalfields. North of
this demarcation line, northern terminals have branched out of
the lingering stratus from last night and now morphing into an
afternoon cumulus field.

Convection will depart the area by late this afternoon with
further progression of the frontal boundary. Excessive low level
moisture festering overhead will work in tandem with clearing
skies to produce river valley fog late tonight into Friday
morning. All sites are anticipated to have favorable conditions
for fog shortly after 09Z tonight, which will then scatter out
after sunrise. Quiet weather is then on tap for Friday as the
front drapes across the Carolinas and high pressure can slither
down into the Central Appalachians.

Winds will remain generally calm throughout the period, with an
occasional puff of wind out of the north in the wake of the
front.

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

FORECAST CONFIDENCE: Medium.

ALTERNATE SCENARIOS: Brief restrictions from isolated storms may
pass near central and southern terminals this afternoon. Timing
and extent of fog overnight may vary from the forecast.
