Area forecast discussion, Aug 16, 2:38 PM EDT, 4 hours 2 minutes before
Area Forecast Discussion
National Weather Service Charleston WV
238 PM EDT TUE AUG 16 2016

.SYNOPSIS...
Diurnal heating and abundant moisture will combine to produce
showers and storms today. Approaching cold front will move through
the forecast area Wednesday, followed by another over the weekend.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
As of 155 PM Tuesday...
Cold front crosses the area overnight tonight. Convection in the
warm sector already occurring aided by the diurnal heating.
Tonight though, there will be some deep layered shear of around 35
knots that could keep pcpn activity going along the front.

Any organized storm can produce heavy rain along their path. Minor
water problems could happen.
An h500 short wave will enhance PCPN activity Wednesday into
Wednesday night.

The front will remain in the vicinity...draped across the
Southern Forecast area on Thursday. Have kept the greatest, likely PoPs
across our Southern zones.

Used the super blend guidance for temperatures through the period.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY NIGHT/...
As of 220 pm Tuesday...
Cold front and upper level short wave support will continue to
move slowly through the region on Wednesday night and exit on
Thursday. This will keep a chance of scattered showers and
thunderstorms in the forecast into Thursday morning. Showers and
thunderstorms will end from west to east Thursday...as the front
slowly exits the area by Thursday evening and stalls just south of
the region. Somewhat cooler and drier air This will keep the area
dry...at least through much of Friday and Friday night.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
As of 230 pm Tuesday...

Models remain in good agreement on a stronger upper level short
wave trough pushing a stronger cold front through the area Sunday.
The front stalled to our south will lift northward on Saturday.
Plainty of moisture out ahead of this system will increase the
chances of showers and thunderstorms. Sunday the front pushes
through and exits on Monday. Cooler and drier air works into the
area late Monday night into Tuesday...as high pressure builds in
across the region. Pretty much stuck with a blend of guidance
temps throughout.

&&

.AVIATION /19Z TUESDAY THROUGH SUNDAY/...
As of 145 PM Tuesday...
A cold front approaches from the northwest tonight increasing
chance for showers and storms. The front should be along the OH
river by 06Z Wednesday, exiting the area by 12Z Wednesday morning.

VFR conditions will prevail at most sites through the period. The
exceptions will be if a site gets hit by a heavy showers or
storms which can produce brief IFR conditions this afternoon and
evening. Coded VCTS at most sites during the same time frame.

Abundant clouds are expected ahead of the front, perhaps to
prevent dense fog formation overnight. However, areas that receive
rainfall today will be more prom to fog tonight.
