AREA FORECAST DISCUSSION
National Weather Service Charleston WV
854 PM EDT Sun Aug 21 2022

.SYNOPSIS...
Showers and storms begin the work week along an advancing cold
front. Drier and warmer conditions are then expected for the
remainder of the work week.

&&

.NEAR TERM /THROUGH MONDAY/...
As of 210 PM Sunday...

Convection has little to no trouble blossoming this afternoon
and will continue to be the case going into this evening. The
atmosphere over the Central Appalachians has gradually
destabilized today with ample sunshine, eating away at any
capping inversion that transpired this morning. Looking
upstream, an eastward propagating upper trough and coincident
surface cold front are crossing through the Ohio Valley, denoted
with a line of quickly developing thunderstorms. Additional
support from shortwaves aloft will yield further development out
ahead of the front and will be the primary concentration of
strong to severe storms for the late afternoon and evening.

Decently strong westerlies aloft will send this line of storms
into the western extent of the forecast area a few hours after
this discussion is published. Simulated reflectivity then
suggests merging precip coverage with diurnally driven activity
along the mountains that will then engulf much of the Central
Appalachians heading into this evening. Jet enhancement will
aid in some storms to reach strong to potentially severe levels,
posing a threat for damaging wind gusts. Cloud tops extending
higher up into the atmosphere may also tap into cold
temperatures aloft that could support instances of hail in the
strongest of storms today.

As the trough and cold front surge into the area overnight, the
potential for showers and storms will be sustained. A gradual
decrease in precip coverage takes shape for the start of the
work week as the frontal boundary completes its passage. The
northern fringes of the forecast area could see the best
potential for showers and storms Monday morning, most likely an
extension of prolonged convection from overnight, but then
finally trailing off at the near/short term forecast break
point.

Temperatures today will struggle to reach their anticipated
highs in the Middle Ohio Valley in response to the inundation of
afternoon cumulus and oncoming convection. Slightly cooler
weather remains in place on Monday in the wake of the frontal
passage.

&&

.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY NIGHT/...
As of 230 PM Sunday...

Monday night the upper level trough will be weakening while tracking
eastward over New York. Widespread showers taper from west to east
by Tuesday morning as low pressure system weakens. A few showers
will be possible Tuesday afternoon as mid level moisture remains and
weak shortwave moves toward the mountains out of Ohio. A surface
ridge builds from the west Tuesday night which will allow patchy
valley fog to develop.

&&

.LONG TERM /WEDNESDAY THROUGH SUNDAY/...
As of 230 PM Sunday...

A broad upper level trough pattern remains overhead through the
end of the week keeping chances of afternoon and evening showers
in the forecast. Afternoon temperatures will trend warmer
through the end of the weak as a ridge builds from the
southwest. There is uncertainty on how much of a hold the ridge
will take heading into the weekend. For now, have continued to
allow the broad brushed mountain showers through the end of the
extended.

&&

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
As of 850 PM Sunday...

Scattered clouds and TCU across the region with a cluster of
showers and thunderstorms in the northern part of our forecast
region. Expecting these to make contact with CKB around 0100Z.
Monitoring the formation of these thunderstorms as models are
indicating there will be scattered thunderstorms this evening
across the region. Timing and location is the main disagreement
for the models. EKN is currently experiencing a round of showers
and there is a cluster of thunderstorms approaching from the
south. These will likely dissipate around 0400Z and usher in a
brief period of fog. Not expecting long lasting fog.
Visibilities will be in the IFR or LIFR range. Expecting this to
lift as a stratus deck moves in. Low stratus deck will form
tonight around 0800-0900Z and then start to lift off around
1700Z. SCT CU will set in afterwards for our afternoon hours.
Once again watching the potential for thunderstorms tomorrow
afternoon and evening. Timing and location will be the
discrepancy but conditions are favorable for scattered storms.

Brief IFR is possible with any thunderstorms. Generally light winds
outside of thunderstorms.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 00Z TUESDAY...

FORECAST CONFIDENCE: Medium to Low.

ALTERNATE SCENARIOS: Timing and location of thunderstorms may
vary. Timing, location, and height of stratus deck may vary.
