AREA FORECAST DISCUSSION
National Weather Service Charleston WV
222 PM EDT Mon Jul 1 2024

.SYNOPSIS...
Cooler and dry to start the work week, then temperatures warm
for Tuesday. Next chance for rain arrives late Wednesday. Semi-
stationary cold front expected on Thursday.

&&

.NEAR TERM /THROUGH TUESDAY/...
As of 1100 AM Monday...

BKN/OVC stratocu has broken up across the higher terrain, with
just a FEW/SCT field across portions of the lowlands. With a
significant dry layer aloft and progged mixing heights up to
~ 4-5 kft, did lower dew points across the region through this
evening. The rest of the forecast remains on track.

As of 757 AM Monday...

Updated cloud cover in/near the mountains over the next few
hours given BKN/OVC skies at present in some areas courtesy of
stratocu. Stratocu will gradually breakup throughout the morning
across the aforementioned areas, leading to a beautiful day
ahead across the region. The rest of the forecast remains on track.

As of 257 AM Monday...

Fresher and drier north to northeast flow provides stable conditions
through tonight, courtesy of a broad high pressure centered over the
Great Lakes. Expect mostly clear skies and comfortable temperatures
with dewpoints lowering into the upper 40s, and afternoon
temperatures ranging from the upper 70s across the lowlands, into
the mid 60s higher elevations. Lows tonight will be below normal as
well with temperatures mainly in the 50s.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY/...
As of 155 PM Monday...

Key Point:
* Chances for rain and storms return Wednesday into Thursday.

An upper level ridge will be present over the southeastern US while
a low traverses central Canada. High pressure should allow dry
weather to persist into Wednesday morning before ridging
compresses south and a shortwave pivoting around the outskirts
of the upper low steers a cold front towards the Middle Ohio
Valley.

Chances of rain and storms are expected to spread northwest to
southeast across the area Wednesday afternoon into Thursday as
the front stalls in the vicinity of the northern CWA border.
Isolated strong to severe storms could be possible mainly along
and west of the Ohio River Wednesday evening. With precipitable
water values climbing to 2 or more inches, heavy downpours are
also likely to accompany storms and could eventually lead to
localized flash flooding in poor drainage areas or locations
that are impacted by multiple storms late Wednesday or Thursday.

Temperatures warm above normal on Wednesday, with mid 70s to upper
80s expected for the mountains and 90s in the lowlands. While
still rather warm, clouds and precipitation should keep
Thursday`s highs a few degrees lower than the previous day.

&&

.LONG TERM /THURSDAY NIGHT THROUGH SUNDAY/...
As of 155 PM Monday...

Key Points:
* Unsettled late week into the weekend.
* Temperatures remain near to above normal through early next week.

The long term forecast period starts out with a frontal boundary
lingering just north of the CWA while a low and upper shortwave
trough depart the Central Plains. This system tracks into the Great
Lakes region on Friday, lifts the stalled boundary to the north as a
warm front, and then ushers a cold front across the area this
weekend. High pressure may slide in at the surface early next week,
however, daytime heating and shortwave energy passing overhead could
still support some afternoon showers and storms.

Temperatures are expected to be near to above normal through early
next week, with highs ranging from 80s to 90s in the lowlands and
mid 70s to upper 80s along the mountains.

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
As of 210 PM Monday...

VFR conditions will prevail throughout the TAF period across
much of the area. The one exception will be with patchy valley
fog tonight, primarily across the river valleys, with the potential
for MVFR/IFR restrictions late tonight at EKN. VCFG fog has been
coded into CRW/PKB for steam fog from associated nearby rivers.
Any fog that develops overnight lifts/dissipates by ~ 12Z on
Tuesday, with a bit of fair weather Cu developing by late morning.

North or northeast surface flow is expected today, with gusts
of 15-20 kts possible through early this evening. Calm or light
southeast flow is expected tonight, with southeast flow
continuing on Tuesday. Gusts of 15-20 kts are possible late
tonight into Tuesday in/near the mountains.
