Area Forecast Discussion
National Weather Service Charleston WV
236 PM EDT MON AUG 15 2016

.SYNOPSIS...
Cold front nearly stationary across Western Ohio, as high
pressure lingers off East Coast. The cold front moves through
Wednesday, followed by another over the weekend.

&&

.NEAR TERM /THROUGH TUESDAY/...
As of 235 PM Monday...

Still looks like an increase in coverage of shra/tsra this afternoon
and evening as vort max tracks out of the S Appalachians and thru
the area. Some of the storms could be on the strong side given the
increase in flow aloft with a hint of low level shear. Damaging
winds would be the primary hazard. Have continued with likely pops
later this afternoon and evening to track this disturbance thru the
area. Given the high PWATS...downpours could produce localized flash
flooding but not enough coverage concerns for a flash flood watch
attm. The most vulnerable areas remain across SE OH and N WV where
1 hr guidance is lowest.

The aforementioned vort max will shift N out of the area by 03z with
clearing overnight. Patchy dense river valley fog is possible over
any locales that receive rain...however...low level flow will
picking up quite a bit to perhaps confine it to the most sheltered
valleys and hollows.

Tuesday will feature a broad strengthening SW flow ahead of the
approaching cold front. As such shra/tsra will be with us
again...most notably across SE OH...close to the better forcing. It
will be a gusty afternoon so despite temps in the low 90s...at least
a breeze will be felt.

&&

.SHORT TERM /TUESDAY NIGHT THROUGH THURSDAY NIGHT/...
As of 235 pm Monday.

A weak cold front crosses Tuesday night, with a good chance for
showers and thunderstorms. A weak upper level short wave trough
trailing behind the one that initially pushes the front through
Tuesday night, crosses Wednesday, keeping the shower/thunderstorm
going.

The shower/thunderstorm chance decreases Wednesday night as the
trailing short wave passes on to the east, with a slight chance
through Thursday mainly on heating and moisture content still
high, before a dry Thursday night ensues per weak surface high
pressure building in.

Temperatures and dew points close to previous package and latest
guidance, bias corrected at night, with just about a 2C
temperature difference in the low levels behind the front.

&&

.LONG TERM /FRIDAY THROUGH SUNDAY/...
As of 235 pm Monday...

Showers and thunderstorms Friday into Saturday will be mainly
diurnally driven, with high pressure exiting to the east, and
upper level light flow/ridging Friday.

Models remain in good agreement on a stronger upper level short
wave trough pushing a stronger cold front through the area Sunday.
This may keep the shower/thunderstorm chance going Saturday
night, with either the approach of the front and / or a wave ahead
of it. Maintained likely pops from previous package for Sunday,
followed by a trend toward drier and somewhat cooler weather early
next week.

Temperatures close to previous package and latest central guidance
and model guidance blends. Very warm weather early on gives way
to cooler weather later in the period, with highs Sunday tempered
by clouds and precipitation, and on Monday in the actual cooler
air. Looking at a comfortably cool night for sleeping at last Monday
night, day night.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
As of 235 PM Monday...

Scattered convection this afternoon and evening will result in IFR
or worse vsby at times for any terminal that gets hit. Inserted a
few hrs IFR tempo groups for KHTS/KCRW/KBKW centered on 21 to 22Z
where confidence was highest as approaching upper levels system from
the S results in a greater coverage of convection. Elsewhere...have
VCTS for the remainder of the afternoon.

Aforementioned system moves to the N this evening with some clearing
tonight. Low level flow increases out of the SW 20 to 25 kts which
will tend to mitigate dense river valley fog...even for terminals
that receive rain. Did put some MVFR in overnight with best chance
for IFR or worse fog at KEKN.

Broad moderate SW flow on Tuesday will result in gusty winds around
20 kts in the afternoon with a cold front approaching SE OH.

FORECAST CONFIDENCE AND ALTERNATE SCENARIOS THROUGH 18Z TUESDAY...

ALTERNATE SCENARIOS: Showers and storms this afternoon and evening could
