Area Forecast Discussion
National Weather Service State College PA
233 PM EDT THU JUN 16 2016

.SYNOPSIS...

A storm system will move down through western Pa later today and
move off the Mid Atlantic coast Friday leaving weather conditions
to improve from north to south in the wake of the storm. A dry
and increasingly warm pattern is expected through Father's Day
weekend and into early next week.

&&

.NEAR TERM /THROUGH TONIGHT/...

Severe Thunderstorm Watch is in effect for much of southern Pa
until 10PM.

An active morning had a line of locally severe storms move
through portions of the northern Laurel Highlands and Central
Mountains. The line is petering out as it moves into more stable
air over the lower Susq Valley.

Western portions of the forecast area will remain the focus of
activity as the airmass destabilizes in the vicinity of a slow
moving warm front.

A cluster of thunderstorm cells extends from just north of
Pittsburgh down to the area west of Johnstown. The main activity
however is expected to continue forming over Ohio in an area of
deep moisture convergence and increasing Cape. These storms are
expected to grow in coverage and intensity and swing trough the
area between about 4 and 9PM.

The focus will likely shift toward potential heavy to excessive
rain event after 17/00z, as low level inflow backs to the
southeast and taps reservoir of 1.75-2.00 inch PWs residing over
the southern Mid Atlantic region. Slowing storm motions and
backbuilding becomes more likely in this scenario, increasing the
risk for flash flooding. There is a consistent, multi-model signal
for locally heavy amounts from the Laurel Highlands and South-
Central Alleghenies down into the WV/MD panhandles. The 16/00z
NCAR HIRES ensemble neighborhood probs show a 'likelihood' of
localized 3+ inch amounts while mean QPF from the SSEO is in the
2-4 inch range. Final QPF was constructed using a blend of WPC and
available HIRES guidance which paints broad area of 1-2 inches
over the aforementioned area. However, given the availability of
high moisture content air feel that the higher amounts in the CAM
guidance is plausible.

Will highlight the duel severe/flash flood risks in the HWO. A
flash flood watch may be needed at shorter ranges and will allow
the next shift to asses the situation as it unfolds.

&&

.SHORT TERM /FRIDAY/...

Friday may dawn cloudy and damp with lingering easterly flow and
a few showers over the southern counties associated with
the departing sfc low. However, all model data indicate we will
see steady improvement and breaking clouds with near seasonal
temps later in the day. Ens mean 8h temps between 12-14c should
translate to max temps in the u70s to around 80F.

&&

.LONG TERM /FRIDAY NIGHT THROUGH THURSDAY/...

Anomalous upper level ridge to our west will begin building into
the region this weekend. Large scale subsidence associated with
this feature should ensure mainly sunny skies,light wind and
seasonable temps Sat.

Medium range model and ensemble guidance continues to show
anomalous upper ridge over the northeast conus into early next
week, which should bring fair weather with increasing warmth. The
next risk for rain returns by Monday night/Tuesday, as a cold
front sinks southward from the Lower Lakes.

Based on latest NAEFS and ECENS a turn toward cooler wx appears
likely by Wed, as upper lvl trof swings thru the Grt Lks and
northeast states. However, too far out to tell if sfc cold front
will completely clear the area, so will maintain chc of showers in
the Wed fcst.

&&

.AVIATION /19Z THURSDAY THROUGH TUESDAY/...
VFR and MVFR conditions early this afternoon will lower to IFR
conditions occasionally during +TSRA this afternoon. The first
round is entering the lower Susquehanna Valley and will exit by
20Z. Popcorn thunderstorms are developing behind this first line.
These will precede another line developing over Ohio. This line
will move over JST and AOO by 22Z. The line will evolve into an
MCS overnight with widespread IFR conditions after 02Z. This new
round of +TSRA will move across the southwest 1/4 to 1/3 of the
airspace with strong to locally svr wind gusts and heavy rainfall
possible. Rain and IFR conditions shift south of the PA/MD line
by midday Friday.

OUTLOOK...

Fri...Morning low cigs/shra possible southern PA. Then VFR.

Sat...No sig wx expected.

Sun...No sig wx expected.

Mon...No sig wx expected.

Tue...Brief MVFR in TSRA
