AREA FORECAST DISCUSSION
National Weather Service Charleston WV
140 PM EDT Tue Jun 17 2025

.SYNOPSIS...
Heavy downpours and flood potential continue today with another
disturbance crossing the area. Strong cold front increases the
severe potential for Thursday.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
As of 345 AM Tuesday...

Key Points:
* Flood Watch in effect from late morning through this evening.
* Isolated storms could produce damaging winds this afternoon
  or evening.

While southwest flow strengthens ahead of a shortwave trough,
warm and moisture rich air will continue to feed into the area
and support rounds of showers and thunderstorms during the day
today. Activity should then persist into the night as the
shortwave pivots overhead.

While lapse rates may be marginal, enough shear and instability
should be present to support a few strong to severe storms this
afternoon into the evening. A marginal risk of severe weather
has been highlighted for portions of northeastern West Virginia,
where isolated storms could produce locally damaging winds.

Precipitable water values will again exceed 1.5 inches, and may
even surpass 2 inches in some areas. While storms should not be
particularly slow moving, heavy downpours may prompt flooding
in locations that have already been saturated by recent heavy
rain. A Flood Watch has been issued for the entire area from
late morning through this evening.

high temperatures are expected to rise into the 80s in the
lowlands and 70s to low 80s along the mountains today. Lows for
tonight remain mild, likely ranging from 60 to 70 degrees.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/...
As of 1205 PM Tuesday...

Unsettled weather pattern, with a warm and humid air mass in place,
continues in the short term period.  Wednesday evening into
Thursday, an upper trough, will push east through the area, with the
frontal boundary that has been located to our north and west,
finally sweeping through the area. Severe weather may be possible
during this period, and spc already has parts of the area
highlighted for Wednesday night and Thursday, with a damaging wind
threat looking to be most likely. Models tend to differ a bit with
the timing of the frontal passage, and a slower timing to the
front/more into the afternoon hours would likely result in a greater
threat for severe on Thursday afternoon than is currently
highlighted. For now, SPC has much of the area in a marginal risk,
with the slight risk located to our east Thursday, with a marginal
risk Wednesday night from any lingering convection that develops to
our west on Wednesday evening and makes its way eastward into our
area. Damaging winds are the primary hazard.

Overall drier weather is expected later Thursday and Friday behind
the departing system, however, occasional light showers cannot be
completely ruled out as additional weak shortwaves cross the
area.

&&

.LONG TERM /SATURDAY THROUGH MONDAY/...
As of 1205 PM Tuesday...

Mainly dry and increasingly hot this weekend into early next week
with a building upper ridge across the eastern U.S. By early next
week, daytime high temperatures should reach the mid 90s across much
of the lowlands. This combined with dew points in the 70s, will
result in heat indices likely hitting advisory criteria Sunday
through Tuesday. An isolated shower or storm is possible during the
afternoons during this period.

&&

.AVIATION /18Z TUESDAY THROUGH SUNDAY/...
As of 130 PM Tuesday...

Mainly VFR conditions with a SCT025 deck that occasionally goes
BKN for MVFR conditions will continue initially as shower and
thunderstorm activity slowly ramps up around the CWA. Any broken
or overcast skies during shower and thunderstorm activity at a
site looks to be mainly in the 020-030 AGL range, but could see
some areas a bit lower or higher. Visibility in heavier showers
and storms could flirt with the IFR threshold, but most precip
will likely be light to moderate and not impact visibility as
much.

SW`ly winds are gusty across much of the area, gusting up to
15kts or so at times, but outside of any t-storm gusts, that
should calm down somewhat overnight for most of the area. The
ample low-level moisture will allow for some areas of mist and
perhaps a bit denser mist or fog in some valleys tonight.
