AREA FORECAST DISCUSSION
National Weather Service Charleston WV
620 AM EDT Tue Jun 17 2025

.SYNOPSIS...
Heavy downpours and flood potential continue today into
Wednesday with another upper level disturbance. Strong cold
front increases the severe potential for Thursday.

&&

.NEAR TERM /THROUGH TONIGHT/...
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 THROUGH THURSDAY NIGHT/...
As of 315 AM Tuesday...

Showers and storms will continue as an H500 shortwave lifts
northeast over our area on Wednesday. Afternoon heating will enhance
storm coverage and intensity under abundant low level moisture.
Under a moist and unstable environment with poor deep layered shear,
isolated strong to severe storms may develop. SPC maintains a
marginal risk for severe thunderstorms for Wednesday and Thursday
mainly during the afternoon and evening hours. Damaging winds will
be the main threat.

With soils across the area are saturated per previous rainfall. It
will take less rain to produce water issues. Therefore, the flash
flood threat can not be rule out if a location receives heavy or
repetitive downpours. However, storm activity should move faster
than previous days allowing to spread rainfall along their path.

A cold front arrives Thursday morning while a stronger H500 trough
pushes east. With similar unstable environment and an uptick in deep
layered shear exceeding 40 knots, better chances for severe
thunderstorms may occur mainly during the afternoon and evening
hours. SPC continues with a marginal risk for severe storms for
Thursday, with a damaging wind threat looking to be most likely.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
As of 315 AM Tuesday...

Forecast weather charts show a surface high pressure building over
the area Friday into the weekend. This high, will provide dry
weather conditions and a warming trend into the beginning of next
week. Afternoon temperatures will climb into the low to mid 90s
across the lowlands, ranging into the upper 70s northeast
mountains for the weekend.

&&

.AVIATION /10Z TUESDAY THROUGH SATURDAY/...
As of 620 AM Tuesday...

Periodic MVFR/IFR remains a possibility today, particularly as
heavier showers and storms develop for the afternoon and
evening. Additional restrictions are likely for the overnight in
fog, low clouds, and as a disturbance brings more rain.

Southwest winds may occasionally gust into the teens this
afternoon, then winds should weaken ans turn southerly for
tonight. Isolated severe storms could also produce locally
strong wind gusts during the afternoon and evening.
