Severe Thunderstorm Warning 119, NWS Charleston, WV

AREA FORECAST DISCUSSION
National Weather Service Charleston WV
157 PM EDT Sun Jun 2 2019

.SYNOPSIS...
Showers and storms today, some severe, with cold front passage.
Monday and Tuesday will be dry and cooler then a warm trend and
unsettled weather returns for the second half of the work week.

&&

.NEAR TERM /THROUGH MONDAY/...
As of 135 PM Sunday...

Today, a well phased trough extends down the eastern CONUS, centered
over Ontario and Quebec. As a shortwave trough rotates around the
mean trough through today, an elongated pressure trough/frontal
boundary pushes through the Ohio Valley and across the spine of
Appalachia providing forcing for widespread showers and storms
during the afternoon into the early evening. At this hour, the
surface front rests across southeast Ohio, evident from storm
activity along it. Instability grows ahead of the surface front
with warm, moist advection, and hires guidance suggests mixed
layer CAPE on the order of 2000-2500 J/kg this afternoon, more
than enough to support strong updrafts and explosive development.
Shear coincident with the front and instability is a bit more
marginal, with 0-6km shear in the 30-35 kt range at best.

All in all, expected scattered showers and storms to continue this
afternoon tracking west to east accompanying the cold front with
a several of these storms packing damaging wind gusts. In line
with SPC's thinking, do think there will be a mainly clusters of
storms and few line segments along the front, especially toward
the north where better shear exists later this afternoon.
Storms spill into southern WV and SW VA roughly 5-7PM as the
front travels south. After this, instability declines and storm
activity outruns better shear toward the north. So, expect
storm activity to quickly decline around and especially after
sundown. Heavy downpours are expected with storms, so isolated
flash flooding is also a possibility, particularly across
central portions of WV where 1-hr flash flood guidance is
1-1.5".

Tonight, a very dry air mass invades behind the upper level
trough axis, quickly cutting post-frontal showers in the
mountains after midnight and scouring out cloud cover across the
lowlands. Skies clear out for the most part by dawn. 850 mb
temperatures manage to dip down to 4-6 deg C by dawn under
strong cold advection, leading to low temperatures overnight in
the 40's across higher elevations, to the low 50's across the
southern coal fields. Cold advection continues Monday, so
in spite of mostly clear skies, a cool NW wind will limit
afternoon high temperatures to the 50's and 60's, perhaps around
70 in the coal fields.

&&

.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/...
As of 400 AM Sunday...

Strong surface high pressure remains in control with mostly
clear skies, a gradual warming trend and dry conditions through
Tuesday. Light southwest low level flow from the southwest will
keep warming trend Tuesday night. A cold front approaches from
the north on Wednesday increasing our chances for showers and
thunderstorms.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
As of 400 AM Sunday...

The weather remains active Wednesday night through the weekend
as a cold front approaches from the north, to become stationary
oriented from west to east by early Thursday. This front is
expected oscillate south to north remain overhead over the
weekend.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
As of 145 PM Sunday...

Showers and storms today with a cold frontal passage, followed
by clearing and a wind shift later this evening. Although VFR
generally prevails early, visibility and perhaps ceilings could
quickly degrade to IFR conditions if a TAF site takes a direct
hit from a storm. Using what's on radar at this hour, storms
will impact PKB for the next hour or two; HTS within the next 3
hours ; CRW roughly 3PM to 5PM ; CKB from now through roughly
5PM ; and EKN from roughly 3 PM to 6PM.

Winds this afternoon are generally from the SW at 5-10 kts and
will turn W after frontal passage, and eventually NW tonight.
Under storms, wind gusts 30-40 kts will be probable with gusts
up to 60 kts possible. With no site immediately in danger of a
storm, decided to stick with 20-30 kt gusts but this may need to
be reevaluated as storms increase in coverage.

A brief bout of MVFR ceiling or perhaps fog is possible at
EKN/CKB/BKW tonight, roughly 07-10Z. Little confidence exists
with this however given very dry air set to rush in behind the
front, so have left prevailing conditions out for now. VFR
conditions prevail through tomorrow otherwise, with mostly sunny
skies and a northwest wind 5-10 kts.
