NWS Charleston, WV wrote its last area forecast discussion before this severe thunderstorm warning went out at May 19, 3:53 PM EDT, 1 hour 55 minutes earlier.

Area forecast discussion, May 19, 3:53 PM EDT, 1 hour 55 minutes before

AREA FORECAST DISCUSSION
National Weather Service Charleston WV
353 PM EDT Sun May 19 2019

.SYNOPSIS...
Cold front Monday. Then, high pressure builds to provide plenty
of sunshine and a gradually warming through Friday along with
chances for showers and thunderstorms.

&&

.NEAR TERM /THROUGH MONDAY/...
As of 150 PM Sunday...

Isolated to scattered convection has indeed developed along the
mountain ridges as of 18Z. The lift for these storms is
primarily due to orographics from strengthening southerly flow,
though not an ideal direction. Latest run of RAP indicates ML
CAPE values are in the 1200 to 1400 J/kg range. The approach of
a mid level trof and associated increase in mid level flow
should allow coverage to increase a bit across these locations
in the thru 21Z. Outside of the high terrain, convection chances
diminish rapidly for the remainder of the afternoon with no
real forcing to lift parcels. Some of the mountain convection
may spill over into the adjacent lowland counties, however
steering flow should motion storms to NNE. Confidence is not
high on this occurring ATTM. Having said that, the best
adjacent lowland locations to see any convection later this
afternoon would be say from Sutton to Clarksburg.

SPC continues to highlight the northern mountains with a slight
risk this afternoon. Shear values are marginal for overall
organization, however surface to mid level delta theta e values
and DCAPE do support a damaging wind potential...primarily with
the stronger collapsing cores.

Mountain/adjacent convective activity will diminish in intensity
and coverage with sunset. The upper trof and associated cold
front will move thru the area tonight. However, with little in
the way instability, I have only low chances for a prefrontal
band of showers moving thru.

A secondary front looks to cross on Monday, however with
moisture confined to the low levels, thinking any precip would
be in the afternoon across the mountains and void of thunder.
CAA and lower dewpoints will arrive across SE OH late in the
afternoon on a refreshing breeze, taking until the evening to
arrive east of the OH River.

&&

.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/...
As of 244 PM Sunday...

A surface high pressure system builds from the northwest to
provide dry and about normal temperatures under light northerly
flow Monday night into Tuesday night. Lows will range from the
lower 50s lowlands to the low 40s highest elevations. Highs
Tuesday will stay a around 70 degrees lowlands ranging into the
upper 50s northeast mountains.

&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
As of 300 PM Sunday...

On Wednesday morning, a warm front develops south of the area
and should gradually lift north under increasing southwest
flow into early Thursday. Then, the area will remain in the warm
sector of an approaching low pressure system. Model's consensus
indicate warm air and moisture advection will gradually
increase through the end of the week. Temperatures will increase
from the mid 80s Wednesday, to around 90 degrees Thursday and
Friday.

Showers and storms will be possible, mainly during the afternoon
and evening hours.

&&

.AVIATION /20Z SUNDAY THROUGH FRIDAY/...
As of 210 PM Sunday...

Mainly scattered mountain shra/tsra thru 00Z with some tempo
MVFR TS groups for EKN/BKN with a SCT to BKN 4-6kft CU field
elsewhere. Some convection my sneak close to CRW and CKB after
21Z such that VCTS was inserted in the TAF, but confidence is
not particularly high on direct impacts. Gusty SW winds 20 to
25 kts will prevail thru the remainder of the afternoon.

After 00Z, a cold front will approach and cross overnight. A few
shra are possible along and ahead of the boundary, though
predominate VFR should be maintained.

A secondary front crosses Monday and with little in the way of
moisture depth, only thinking isolated shra in the afternoon for
the mountains and dry elsewhere. Some morning MVFR stratus is
possible across SE OH but should stay clear of PKB/HTS. Winds
will become gusty in the afternoon 20 to 25 kts and veering to
the W and eventually WNW with any BKN CU becoming SCT.

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