Area Forecast Discussion
National Weather Service Charleston WV
551 PM EDT Wed Jun 27 2018

.SYNOPSIS...
A cold front will affect the area tonight. High pressure
arrives Thursday. Heat wave Friday through at least Tuesday.

&&

.NEAR TERM /THROUGH THURSDAY/...
As of 550 PM Wednesday...

Based on latest radar mosaic and model guidance, have made some
tweaks to the pops. Looks like there will be a minimum in storms
across portions of the southern coalfields for the next few
hours. So have low chance to slight chance pops across that
location for the next few hours.

Pops will then ramp up as the cold front approaches from the
northwest. SPC has dropped marginal risk across our entire area.

As of 215 PM Wednesday...
Warm front looks to be draped across northeast Ohio and
northeastern WV as of 18Z. This front will continue to move
northeast through the afternoon. Clouds will scatter some in
warm sector per say, allowing insolation to destabilized the
boundary layer. This will lead to popup shra/tsra for the late
afternoon in broad upper level diffluence amid a strengthening
low level southwesterly wind profile. With lack of a well
defined forcing mechanism, coverage should remain scattered at
best. The cold front, currently across northwest OH, will
progress toward southeast OH early this evening. This will serve
as the main focus for organized convection heading. SPC
maintains a marginal risk for severe today, though it appears
the greatest threat would be tied closer to the front and upper
level s/w trof. Hence, southeast OH would be in line early this
evening for an isolated damaging wind threat. While the front
will likely stall across southeast OH and extreme northern WV
late this evening, it appears the activity from earlier in the
evening will progress off the front and deep into the CWA before
waning late across southern counties. Expect low stratus to
develop late tonight and linger through at least mid morning,
before lifting into a healthy cu field for the afternoon.

Temperatures were derived from the hires wrf and NBM for lows as
well as highs tomorrow.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY NIGHT/...
As of 320 PM Wednesday...

A surface high pressure system and upper level ridge will
remain for Thursday night through Saturday night, allowing for
heat and humidity to start increasing. With dry air in the low
levels on Friday, will lower afternoon dew points a bit.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
As of 320 PM Wednesday...

The upper level ridge will remain through the weekend allowing
heat and humidity to continue building. Enough moisture may
build toward the end of the weekend to allow for a couple of
afternoon thunderstorms.

The combination of hot temperatures and high humidity could
produce heat indices in the lower 100s Saturday and Sunday
afternoon.

An approaching cold front will then increase precipitation
chances for the beginning of the work week. Models differ on the
handling of this front, with some pushing it further south than
others. Fronts generally have a hard time pushing south of the
area this time of year, so think that the models that keep the
front over the region are probably handling it better.

&&

.AVIATION /22Z WEDNESDAY THROUGH MONDAY/...
As of 220 PM Wednesday...

Isolated to scattered shra/tsra through 00Z in a warm moist
boundary layer within the warm sector. This was handled with
VCTS at the various terminals. A cold front will approach this
evening, but likely stall across southeast OH and northern WV.
A broken line of shra/tsra along and ahead of the front will
continue to move through the area though, likely affecting all
terminals. VCTS was coded up once again to account for this,
especially given the uncertainty of the extent of any
convection this evening.

There is good agreement amongst the guidance on low stratus
forming at most sites overnight, with IFR or worse CIGs
developing. Boundary layer winds around 20 kts will likely
mitigate dense fog, save for EKN perhaps. Low stratus will
slowly lift and scatter into a health cu field by mid to later
morning.

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

FORECAST CONFIDENCE: Medium.

ALTERNATE SCENARIOS:  Timing and coverage of showers and
thunderstorms may vary tonight. Timing of low stratus
development may vary during the early morning hours Thursday.
