Area Forecast Discussion
National Weather Service State College PA
148 AM EST Sat Jan 7 2017

.SYNOPSIS...
A cold weather pattern with below normal temperatures and lake
effect snow will stay locked in through the weekend before
moderating next week.

&&

.NEAR TERM /UNTIL NOON TODAY/...
Lake effect still huggingn the LE shoreline and keeping away from
the CWA at this point. More interestingly, the storm deepening
along the SE coast is already making radar returns into PA as it
throws decent moisture over the cold dome. The ol' dendritic snow
growth zone (DGZ) is rather deep over KLNS per RUC and HRRR
soundings. It is also poised to get a good/deep influx of
moisture over the SErn tip of the CWA. The tight gradient of snow-
no snow advertised well thus far may push NW a little more than
earlier thought. So, a fluffy 1-2 inches is possible across the
southern third of York and Lancaster counties, and a dusting is
possible over most of those two counties and Adams county, as
well. Hardly anything to worry about. It is January after all. The
wave will pull the snow away late this morning and very early in
the afternoon. The lake effect clouds should slide south a bit
this morning, but should stay mainly N of the area. Expect them to
make better in roads later in the day.

&&

.SHORT TERM /NOON TODAY THROUGH 6 PM SUNDAY/...
An upper trough over the lower Great Lakes/Ohio will keep the
mention of lake effect snow showers in the far NW mountains, but
with accums generally an inch or less. Any light snow that might
creep into York or Lancaster counties late tonight will move east
of the area by mid morning with improving skies thereafter.

Highs will range from the mid teens to mid 20s from NW to SE.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Surface low is well off the east coast with high pressure
centered over Iowa. NW flow continues with cold air advection.The
cold bottoms out on Sunday with passage of -20C air at 850mb. Max
temps are projected to average 10 to 20 degrees below normal for
early January. Gusty winds should drop wind chills below zero
across the Alleghenies and into the single digits over the Lower
Susq Valley. A Short-wave moves southeast across the Eastern Great
Lakes Saturday night bringing some snow to the northern zones and
then the lake effect fetch becoming more favorable into Sunday -
bringing an enhanced period for potential lake effect snows over
the NW. During the day on Sunday, we could also see these bands
snake into the central mountains and a quick accumulation is poss.

Center of the high passes to the south on Monday with return flow
kicking in and expected to moderate temperatures through early
next week. High clouds over western PA with warm air advection.
The next shot of precip will arrive on Tuesday with high prob of
ptype issues as strong SW flow directs warm air into retreating
cold dome. Without getting too detailed, latest runs still showing
colder air trapped for much of Tue into Tue night, so continued to
mention a wintry mix. By Wed, precip should change to all rain
ahead and along a cold front with a soggy day in store.

Models now trending a little milder for the end of the week.

&&

.AVIATION /06Z SATURDAY THROUGH WEDNESDAY/...
High pressure ridge over Pa will ensure VFR conditions overnight
across most of Central Pa. Only exception could be some MVFR
stratocu currently observed in the vicinity of BFD and JST.

The northern edge of a snow shield associated with a coastal
storm will graze Southeast Pa later today, likely resulting in a
brief period of IFR vsby at LNS sometime between 13Z-17Z.
Otherwise, widespread VFR conditions expected late this morning.
An increasing NW flow this afternoon will likely yield MVFR
stratocu and flurries at BFD and JST after 18Z, with a high
confidence of VFR conditions further east (downwind) of the
mountains. Deepening moisture downwind of the lakes indicated by
model soundings tonight, indicating the potential of IFR vis
reductions in light snow at BFD after about 03Z.

Outlook...

Sun...Snow showers with IFR/MVFR vsby lkly BFD and JST.

Mon...No sig wx expected.

Tue...Low CIGS/mixed precipitation possible, esp NW Pa. LLWS.

Wed...AM rain showers/reduced CIGS possible.

&&

.CTP WATCHES/WARNINGS/ADVISORIES...
None.
