...A BAND OF HEAVY SNOW WILL AFFECT PARTS OF CENTRE... 
CLEARFIELD...BLAIR...AND HUNTINGDON COUNTIES...

HAZARDS...A band of heavy snow accompanied by winds of 20 MPH which
can rapidly reduce visibility to less than a quarter of a mile.

LOCATION AND MOVEMENT...At 346 AM EST, a band of heavy snow was along
a line extending from near Karthaus to Park Forest Village and moving
west at 20 MPH.

For those driving on Interstate 80, this includes areas between the
Dubois Route 255 and Milesburg exits, specifically from mile markers
108 to 149.

This includes Interstate 99 from mile markers 37 to 73.

This includes the following highways...
 Route 322 from east of Rockton to State College.
 State Road 153 from near S.B. Elliot State Park to Penfield.
 State Road 350 from Philipsburg to Bald Eagle.
 State Road 453 from Tyrone to east of Tyrone.

SAFETY INFO...
Use extra caution if you must travel into or through this band of
heavy snow. Rapid changes in visibility and potentially slick roads
are likely to lead to accidents. Consider delaying travel until this
band of heavy snow passes your location.

Conditions can deteriorate rapidly in winter weather situations. Be
prepared for snow or ice covered roads. Slow down and allow extra
time to reach your destination.

What forecasters said that day

The local office's own words before this special weather statement went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS State College, PA wrote its last area forecast discussion before this special weather statement went out at Feb 2, 1:51 AM EST, 1 hour 56 minutes earlier.

Area forecast discussion, Feb 2, 1:51 AM EST, 1 hour 56 minutes before
Area Forecast Discussion
National Weather Service State College PA
151 AM EST Tue Feb 2 2021

.SYNOPSIS...
Snow will taper off this Groundhog Day with drier air moving in
from the north. Gusty winds will continue today and Wed until
the Nor'Easter makes it into the Maritimes. The next weather
system is forecast to arrive late Thursda or Friday. Another
potent winter storm system is possible late in the weekend and
may be followed by an arctic outbreak into early next week.

&&

.NEAR TERM /THROUGH TODAY/...
Still watching the snow fall outside and over most of Central PA
at this hour. Meso models keep the highest additional totals up
in Sullivan Co through the morning. They could pick up an
additional 3-4 while the lighter intensity elsewhere will likely
only add another 1-2" at most through sunset. The sfc low will
still be deepening ver very slightly off NJ, and will be close
enough to continue the blustery, gustery wind all day. Gusts may
get into the m30s (mph) over the srn half and far NE/Poconos.

Prev...
Measurable snow still falling over much of central PA late this
evening, although intensity has been dropping off steadily while
vsbys slowly increase as well. Steadiest snowfall occurring in
cold conveyor belt/remnant deformation/frontogentical bands
streaming from the Pocono Plateau through my eastern, central
and south central zones. Most places west of SR 15 are looking
at an additional coating to locally 1"+ of accumulation through
early Tuesday morning, while the east and northeast are likely
to see an additional 2-4". Drier air is bleeding southward in
the low levels as evidenced by KN38 and KIPT, and likely is the
result of thermally direct ageostrophic circulation in response
to those earlier/now weakening fgen bands.

We'll be in the northeast residual snowfall for several more
hours with generally light accums persisting into early Tuesday
morning. Additional light amounts are expected although the
bulk of heavy accums have already occurred. Some localized
reports of 18" plus being received in Northumberland and
Schuylkill Counties. Much of the areas saw between 8 and 14
inches. Check the latest PITPNSCTP online or on social media for
these reports. A preliminary snow accum map has been posted to
our Facebook page, also soliciting additional public reports.
THANKS TO ALL who've measured and submitted storm totals!

&&

.SHORT TERM /TONIGHT THROUGH 6 PM WEDNESDAY/...
Slow moving upper low pivoting over the northern Mid Atlantic
states toward New England will keep light snow going over most
of CPA for Groundhog Day. Additional amounts should generally
range from 0.5" up to 2 inches.

A tightening pressure gradient west of intensifying low over
eastern New England will result in increasingly gusty northwest
winds across central Pa by Tuesday. Bufkit soundings support
gusts of 25-30kts by afternoon, which could produce some
blowing/drifting in open/exposed locations.

Not much change in maxT for tomorrow, but it will feel colder
with a blustery NNW wind. Combo of gusty NW flow and cloud
cover should tilt Tue night minT toward the warm side of
guidance in areas downwind of the Alleghenies.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH MONDAY/...
The upper low is progged to finally pull away from the region
by Wednesday, causing clearing skies, especially downwind (east)
of the Alleghenies. Model soundings vertically mix to around 900mb
Wednesday afternoon, supporting near seasonable highs and still
gusty northwest winds around 25 kts at times.

Dry weather is expected Thursday with a decent amount of
sunshine, as a ridge of high pressure ridge slides east across
the region with temperatures rising to several degrees warmer
than average Thursday and Friday.

By late in the week, operational model and EFS guidance comes
into some better agreement with the amplitude and speed of an
upper level trough moving in from the west. Trough dropping
across the midwest with developing surface low over the Great
Lakes will lift a warm front through Thursday night followed by
a cold front on Friday, brushing mainly western areas with
precipitation. Generally light snow for the NW and light rain
for the SE, though steadiest precip remains confined to NW half
of CWA into the weekend. Models are also in better agreement
that precipitation will exit by Friday night, with clearing
skies in the southeast for Saturday.

By Sunday, some significant differences emerge between the
global models. The EC and GFS both agree that a deep mid-level
trough will dig into the midwest Sunday afternoon and evening,
with a surface low racing up the east coast ahead of it. At this
point, both the GEFS and ECENS don't sync up these systems,
keeping significant winter impacts at bay. However, the 12Z
operational EC run shows a robust nor'easter with significant
winter impacts for parts of PA Sunday and Sunday night. At this
point, it's way too early to make much of next weekend's
systems, but have kept chance PoPs throughout the day Sunday.

The bigger story at this point looks to be a sure bet for the
coldest air of the season to settle in behind the aforementioned
system. 850mb temps near -20C Monday could result in below zero
MinTs Monday and Tuesday mornings, with wind chills plunging
into the -10s. Cold air is likely to stay in place through at
least mid-February, providing some of the coldest temperatures
in at least a couple years across Central PA.

&&

.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
Long duration IFR continues with broad field of -SN and <=2SM
visibility across most of Central PA. Hi-resolution model
guidance indicates snow showers should weaken after midnight,
but have maintained fairly pessimistic cigs at central/SW
airfields through daybreak.

The big story Tuesday will be the quick increase in NW winds
and gusts conservatively between 25 and 30kts at many airfields
from the late morning through the afternoon hours. Scattered
snow showers will persist through much of the day, bringing
brief reductions into the MVFR range for cigs and vsbys, mainly
across the northern mtns.

Expect additional reductions at BFD and JST by afternoon thanks
to northwesterly flow building in with continued gustiness into
the overnight hours.

Outlook...

Wed...Breezy with 20-25kt wind gusts from 280-310 degrees.

Thu...No sig wx.

Thu night-Fri...Reductions possible in mixed pcpn.

Sat...VFR as a weak ridge of high pres slides east across PA.

Harrisburg:   4.6 Sun + 7.9 Mon = 12.5
