Area Forecast Discussion
National Weather Service State College PA
214 AM EST Sat Nov 19 2016

.SYNOPSIS...
Strengthening low pressure will track north of Pennsylvania
Saturday, pushing a strong cold front through the state. Gusty
northwest winds, well below normal temperatures, and frequent
mountain snow showers are expected over the rest of the weekend.
High pressure will build in by Tuesday.

&&

.NEAR TERM /UNTIL 8 AM THIS MORNING/...
Clear skies and a calm wind allowing temps to fall through the 30s
early this morning in the valleys of Eastern Pa, resulting in
patchy valley fog. The mildest readings overnight will be over
the Allegheny Plateau, where a light southerly breeze should hold
temps to the 45-50F range. A weaker gradient and calm wind should
allow for more radiational cooling across the eastern half of the
state with min temps in the 30s to low 40s.

&&

.SHORT TERM /8 AM THIS MORNING THROUGH 6 PM SUNDAY/...
Big transition day Saturday with respect to clouds, precip (and
type), wind and temps as a strong cold front plows east across the
region.

The timing of the cfropa is about 15-16Z across the NW mtns and
Laurel Highlands...17-19Z through the central zones...and 20-22Z
across the Susq Valley and Wrn Poconos. Expect a few areas of
light to moderate showers...and perhaps even a NCFRB with brief
heavy rain and strong westerly wind gusts of 45-50 mph right along
the cold front.

Although Thunder is a low possibility as the system is vigorous,
dewpoints are rather paltry, and only result in sfc-based and ML
capes of just 100 j/kg or less. Therefore, it's still not worth
highlighting in the forecast, considering the other higher
profile weather elements such as the wind, falling temps and then
snow showers.

Rainfall amts should be 1-3 tenths of an inch...and POPs were
boosted 10-30 percent higher than the NBM guidance (especially
across the NW mtns and Laurel Highlands.

Bufkit soundings suggest a very sharp drop in temps of 20-25 deg F
within the first 3-4 hours of the frontal passage. 925 mb temps
fall below 0C along and to the west of Route 219 in wrn PA by 21Z
changing any showers quickly to some SHSN. A flash freeze of wet
pavement is possible around dusk Saturday...with scattered snow
showers across the central and western zones...and rain showers
departing the eastern zones.

Lake Effect Snow Watch, Lake Effect Snow Advisory, and a Winter
Weather Advisory were posted for 21Z Sat through at least 00Z
Monday for the NW mtns and Laurels.

Considering the nose of very deep cold air with -7 to -9C 850
temps spreading across the region (and still warm Lower Glakes
with temps of 10-13C), there will be very steep low-mid level
lapse rates and an excellent setup for an early season significant
Lake Effect and Orographic moderate to heavy snow event across the
NW Mtns and Laurels.

Very tight llvl p-gradient will also result in strong, gusty west
to NW winds AOA 40 kts. This wind was covered so far in the
Hazardous Weather Outlook (and winter weather products across the
western mtns). Later shifts/forecast updates will need to consider
posting a Wind Advisory for the rest of the Central Mtns and Susq
Valley.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Accumulating lake effect snow is likely Saturday night into
Monday. Coldest air of the season builds over northern PA with 850
mb temps of -10C to -12C with well-aligned moderate to strong WNW
llvl flow. Post frontal northwesterlies should be quite robust on
Sunday as this cold air blasts southeastward across the lakes.

Likelihood exists for several inches or more of lake effect
snowfall in the preferred locations between Saturday night through
Sunday and into Monday morning. The other primary weather concern
will be the strong NW winds, which could potentially reach
advisory criteria later Sat night through Sun night based on
latest Bufkit soundings that tap 50-60 kts of wind at 4-5 kft agl.

Northwest flow will persist into Monday with lingering snow
showers downstream of LE but dry and cold in the S/E. All med
range guidance indicating fair wx Tuesday with passage of high
pressure ridge. Latest GEFS and EC guidance tracks a weakening
1010mb sfc low from Mich to New York State Wed night/Thu,
suggesting that a period of slightly milder/showery weather is
likely at that time. Since secondary sfc low development is
possible near the Delmarva or Mid Atl coast Thursday afternoon and
evening, it may be tough to scour out the cold air, and some
higher elevation mixed precip is possible.

A chilly...mainly dry airmass will follow for late next week into
Saturday. Gusty NW possible Friday as the aforementioned coastal
low winds up south of Cape Cod.

&&

.AVIATION /07Z SATURDAY THROUGH WEDNESDAY/...
Overall, VFR conditions with light winds will prevail across the
region through Saturday morning. Could see MVFR vsby in fog Sat
morn in the Susq Valley. Also, winds aloft begin to increase ahead
of an approaching strong cold front - so mentioned LLWS arriving
at KBFD after 06z Sat. Some LLWS out ahead of the front expected
however the strongest shear should remain above 3KFT. The biggest
issue with the wind shear will be directional with winds at the
SFC out of the south and winds aloft out of the northwest.

Big changes arrive later Sat behind the cold front. A period of
strong gusty WNW winds expected to develop - peaking Sun into Sun
night. Rain showers impact much of central PA later Sat, then a
period of snow showers with reduced cigs/vsby likely at KBFD/KJST
Sat night into Mon. Some snow showers could reach into KUNV Sun
night into Mon.

Outlook...

Sat...Patchy AM fog possible. Snow showers/low vsbys possible Sat
night KBFD/KJST.

Sat night-Mon...Strong/gusty NW winds. Gusts frequently between
35-45 mph later Sat night through Sunday night. Snow
showers/reduced vsby likely at KBFD/KJST. Ocnl MVFR cigs with
flurries and brief snow showers across the Central Mtn airfields -
KAOO, KUNV and KIPT with mainly VFR invof KMDT, KLNS and KTHV.

Tues...Morning MVFR cigs possible across the northern and western
mtns of PA...otherwise decreasing wind and improving conditions to
mainly VFR.

Wed...No significant weather expected.
