Severe Thunderstorm Warning 32, NWS Charleston, WV

AREA FORECAST DISCUSSION
National Weather Service Charleston WV
326 PM EDT Thu May 19 2022

.SYNOPSIS...
A boundary lifts northward across the region tonight with
shower/storm chances. Hot weather Friday/Saturday. A cold front
crosses late Sunday, with a cooler start to the new work week.

&&

.NEAR TERM /THROUGH FRIDAY/...
As of 300 PM Thursday...

Lingering stratus deck across portions of the region has broken
into stratocumulus, providing for a warm, pleasant afternoon
across the region with high temperatures topping out in the
upper 70s to low 80s for the lowlands. Shower and thunderstorm
activity is beginning to develop just to the south of the region
along a lingering frontal boundary. This boundary will gradually
lift northwards across the area late this evening through the
overnight period, serving as a focusing mechanism for shower and
thunderstorm development. Portions of the southern/western CWA
have been upgraded into a slight risk for severe weather as a
result, with the main threats being damaging wind gusts, large
hail, and heavy downpours. A few water issues and an isolated
tornado are also possible. Greatest threat for severe weather
will be confined to southern WV, southwest VA, and the Mid-Ohio
Valley. Overnight low temperatures will generally be in the low
to mid 60s for much of the CWA, with 50s across the eastern
mountains.

The aforementioned surface boundary is progged to lift north of
the area by mid morning on Friday. This provides the area with
a hot and dry Friday. High temperatures are progged to reach
the low to mid 90s across the lowlands, translating into the
warmest day of the year thus far. Dew points in the low to mid
60s help to keep heat indices below that of heat advisory
criteria. Sensitive groups should however limit time outside
tomorrow and take precautions if outdoors, given that it will
be the warmest day of the year thus far.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SUNDAY/...
As of 140 PM Thursday...

Continued hot and humid across the forecast area on Saturday, with
strengthening ridge along eastern U.S. A disturbance moving through
the area on Saturday afternoon/evening will help to kick off showers
and storms across the area, particularly across the far eastern
zones. Overnight low temperatures Saturday night will be quite
muggy, with lows most areas expected to remain in the 60s.

&&

.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
As of 1230 PM Thursday...

Cold front will move into the area late Sunday
afternoon/evening, with showers and thunderstorms increasing
across the area as it does so. Still some uncertainty in terms
of any severe, but overall threat is looking to be rather low
owing to lack of significant shear or upper dynamics. Period
still bears watching however. In addition, brief heavy downpours
can be expected from any convection that develops with
anomalously high PW air taking hold across the region.

Frontal boundary will clear the area late Sunday night into
Monday, with additional showers lingering across the region.

Weather pattern becomes more uncertain from Tuesday onward, but
general consensus is for an active pattern to continue, along
with a gradual warming trend.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
As of 215 PM Thursday...

Mainly VFR conditions persist this afternoon across the area
with brief MVFR CIG restrictions at times courtesy of
stratocumulus. Brief MVFR CIG restrictions will continue to be
possible through early this evening.

VFR conditions will then continue through much of the overnight
across the region as a frontal boundary lifts northwards across
the area. Some showers and isolated thunderstorms will be
possible, but given low confidence in location of activity, kept
mention of showers and thunderstorms out of most of the TAFs
for now. Precipitation chances should generally end across the
region by dawn tomorrow morning as the front exits north, with
VFR conditions continuing through the end of the TAF period.

A general S/SW flow will continue through much of the TAF
period. Gusty winds at times this afternoon become lighter
tonight. Winds become gusty again near dawn tomorrow morning and
remain as such through the end of the TAF period.

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

FORECAST CONFIDENCE: Medium to high.

ALTERNATE SCENARIOS: Very brief MVFR CIG restrictions possible
through mid evening. Coverage and timing of shower/storms
tonight could vary from what is progged in the TAFs.
