.KEY MESSAGES...
1) Diurnally driven showers and storms are anticipated to spawn
over the next few hours across the eastern half of the forecast
area today.

2) Active weather extends into the start of the weekend as a
cold front drives through the Central Appalachians by Saturday
night. Thunderstorm development preceding the frontal passage
may foster damaging wind gusts and hail.

3) High pressure building in for the start of the new work week
will yield a stretch of dry weather and below normal
temperatures across parts of the Ohio Valley.

.DISCUSSION...
KEY MESSAGE 1...

Radar trends thus far today have kept the bulk of activity
associated with a southern stream disturbance east of the
Appalachians. However, additional development in Kentucky at the
time of writing within blossoming cumulus signals
destabilization that bears a similar environment to parts of the
central lowlands. Hi-res modeling fires up a line of diurnally
driven storms along the foothills and mountains for this
afternoon and fading off after sunset. Leftover moisture will
once again promote locally dense fog and low level stratus late
tonight into Saturday morning.


KEY MESSAGE 2...

Amplification of an upper level trough, coupled with shortwave
energy, will drive a cold front through the Ohio Valley for the
start of the weekend. Daytime heating will lead to typical
summertime destabilization ahead of the front, prompting
blossoming cumulus fields and scattered shower and storm
development. Storm initiation preceding FROPA may begin as early
as 2 PM across the Ohio River Valley and also along the higher
terrain with assistance from upslope lift.

Radar will then remain active through the course of the
afternoon and evening with the eastward push of the front,
currently aiming for an arrival time into the forecast area by
late Saturday night. One last line of showers and storms aligned
along the boundary presses through overnight into Sunday
morning, lingering longest along the higher terrain for the end
of the weekend.


KEY MESSAGE 3...

While some lingering precipitation along the northeast WV
mountains may be ongoing for the start of the day Sunday, a
multi-day dry weather pattern is progged to arrive for the end
of the weekend/start of next week under the guise of building
high pressure. This stretch of dry weather will aid in soil
recovery in the wake of what has been a very wet month across
the bulk of the forecast area.

Temperatures are also anticipated to fall below climatological
norms in the wake of the frontal passage, with daytime highs
reaching the 60s along the mountains and 70s to low 80s across
the lowlands. Overnight lows will also cool down into the 40s
and 50s during this time.

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
More dense valley fog is expected this morning except for
HTS/BKW who should have enough surface flow to deter fog
formation. HTS obs are not updating therefore AMD NOT SKED.
Outside the valley fog VFR conditions will prevail after 13Z
except for tonight when lower CIGs takeover due to post frontal
stratus. Some shower activity is anticipated this afternoon
along with possible thunderstorms, however no restrictions are
expected unless a site is directly hit. Winds will be out of
the southwest and light except may increase some for the
afternoon and change out of the west as frontal passage takes
place tonight.
