National Weather Service Charleston WV
609 AM EDT Mon Jun 22 2026

.WHAT HAS CHANGED...
A Flood Watch for flash flooding has been issued across much of
the forecast area from 8 AM today until 11 PM. In addition, the
Slight Risk for severe thunderstorms this afternoon and evening
has been expanded. Finally, updated aviation discussion.

&&

.KEY MESSAGES...
- 1) A potent system for the beginning of astronomical summer
  brings heavy rainfall which could lead to flash flooding
  concerns, as well as strong to severe storms, to the area on
  Monday.

- 2) Drier, cooler weather returns for midweek, before a more
  active weather pattern returns for late Thursday through the
  weekend, amid increasing warmth and humidity.

.DISCUSSION...
KEY MESSAGE 1...

Low pressure, currently centered across central Indiana, will be
the main area of focus over the next 24 hours, bringing
multiple hazards to the area in the form of severe thunderstorm
and flash flooding potential. At present, an associated warm
front is lifting through the northern CWA, with the cold front
off to the west across the central Ohio Valley. Scattered
showers and a few storms have moved into western portions of the
forecast area, with more activity off to the west associated
with a low-level jet. This initial activity is expected to
weaken, with rounds of showers and storms then developing
throughout the day in the open warm sector amid progged Mixed-
layer CAPE of 1,000-1,500 J/Kg, along with fairly robust
kinematic fields for late June. Strong to severe thunderstorms
are expected to develop in the afternoon/evening ahead of the cold
front as it approaches, with the SPC having most locations
south of the Ohio River under a Slight Risk for severe
thunderstorms, while a Marginal Risk further to the northwest.
The primary threat with severe storms will be damaging wind
gusts. Freezing levels of 13-14 kft should limit the hail
threat, although a few instances of marginally severe hail
cannot be ruled out. An isolated tornado or two remains possible
given progged 0-3km SRH values of 100-200 m2/s2 across portions
of the forecast area, especially northeast. Any severe threat
quickly tapers by late evening following the passage of the
aforementioned cold front.

The other aspect of today will be the potential for heavy
rainfall and flash flooding. PW values of 1.7-2.0"+ will
facilitate heavy rainfall within thunderstorms, with multiple
rounds expected in some areas. Guidance varies in terms of
the placement of heaviest rainfall, but all CAMs depict
corridors of 1-2"+ of rainfall across portions of the CWA, with
embedded higher amounts. Given recent heavy rainfall across the
CWA, and after collaborating with neighboring offices, have
issued a Flood Watch for flash flooding for much of the CWA from
8 AM this morning until 11 PM this evening. Locations that
received the higher rainfall totals last week will be most
susceptible to flooding, especially given any training of
thunderstorms today. Highs temperatures will be in the upper
70s to low 80s across the lowlands, amid breezy southwest winds.
Rainfall will quickly taper from northwest to southeast this
evening into tonight, potentially lingering to dawn in the
mountains. Patchy fog could occur in some areas later tonight.

KEY MESSAGE 2...

High pressure brings a dry, tranquil period for midweek, with below
normal temperatures and early morning dense valley fog.

The chance for showers and storms returns Thursday afternoon
onward courtesy of a meandering front that will setup (more or
less) east to west across the region. Activity will be
diurnally driven to a degree, with periodic mid/upper level
waves moving across the area at times enhancing rainfall
activity. Rain chances should begin to decrease towards the end
of the forecast period (late weekend) as a stout upper ridge
begins to build overhead.

Seasonable to slightly above normal temperatures are progged to
return Thursday onward amid gradually increasing humidity.

.AVIATION /09Z MONDAY THROUGH FRIDAY/...
Rounds of scattered showers and storms are expected across the
area throughout today, with coverage progged to be greatest
during the afternoon and evening hours, thereafter becoming more
confined to the higher terrain for the overnight. Strong, heavy
storms are expected across portions of the area during the
afternoon and evening, resulting in brief MVFR/IFR VSBY in some
areas, along with strong gusty winds. MVFR CIGs are possible
during the day across the north, primarily impacting PKB. CIGs
will quickly lower into IFR/LIFR late Monday evening into the
overnight following the passage of a cold front, with the
potential for patchy fog in some areas.

South to southeast flow currently will veer to southwest area-
wide by mid-morning, then remain as such throughout the day.
Surface flow then veers to NNW after ~00Z Tuesday following the
passage of the cold front. Gusts of 20-25 kts are possible
during the day today, higher with any thunderstorms.
