What forecasters said that day

The local office's own words before this wind chill warning 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 wind chill warning went out at Jan 4, 1:37 AM EST, 2 hours 9 minutes earlier.

Area forecast discussion, Jan 4, 1:37 AM EST, 2 hours 9 minutes before
Area Forecast Discussion
National Weather Service State College PA
137 AM EST Thu Jan 4 2018

.SYNOPSIS...
A deep and cold upper trough will dominate our weather through
early Sunday. A strong coastal storm will lift northward along
the eastern seaboard over the next 24 hours and will bring some
light snow to southeastern areas overnight and Thursday. The
low will also produce strong winds over the region. An arctic
air mass moves in Thursday and will likely produce some of the
coldest weather of the season to date. Moderating temperatures
by late weekend and early next week could bring a wintry mix to
much of the region.

&&

.NEAR TERM /UNTIL 6 AM THURSDAY MORNING/...
Clouds increasing from the south early this morning with light
snow breaking out over eastern Lancaster/York counties as strong
storm moves up the East Coast, and short-wave and arctic front
apoproach from the NW.

Significant (Advisory) snow will impact my southeast counties,
but heavy snow is still expected to remain to our east. Winter
weather advisory for 1 to 4 inches of snow expected for our
southeastern counties remains in effect with no changes planned.

The arctic air comes into the west with snow showers and
increasing winds. Windchill issue increase Thursday AM and this
cold surge should eventually produce some LES but not in this
time period.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM FRIDAY/...
Any light snow in the east diminishes as the storm lifts to our
north and east. The deep low to our east and the high to our
west will increase the winds across the commonwealth.

The 850 hPa temperatures should fall to -20C Thursday afternoon
as the arctic air continues to move over the region. Our 850 hPa
temperatures should bottom out Fri-Sat in the -24 to -26F range!

The 850 hPa winds with this system will be NNW which will favor
the development of LES and orographic snows. Some of the best
flow for western PA LES this winter. The last event had more
westerly flow favoring single large bands. This event should get
more snow in Warren and McKean Counties and into Clearfield,
Cambria and Somerset Counties. Event the coarse GEFS shows the
potential for an enduring northwest flow LES/orographic snow
event developing Thursday afternoon and evening.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Powerful winter storm moving up the east coast will be barreling
into New England to start the period, with biggest impacts to
our east and northeast. In its wake, dangerously cold wind
chills and the lake effect snow machine will be the main story
for Thursday night into Saturday as the most brutal shot of
arctic air thus far sweeps across the region. Models are in good
agreement with a strong northwest gradient producing brisk
winds as well. 850mb winds Friday morning and afternoon are
upwards of 50kts. That will mean 20 to 25 mph gusts at the
surface across central PA.

High temperatures Friday and Saturday will only manage the
single digits...with wind chills of 20 below to potentially up
to 30 below zero across western and northern areas late Thursday
night through Saturday. The Wind Chill Watch continues there,
with that likely transitioning to a Warning (at least for
portions of the northern mountains and Laurels) as event nears.
A Wind Chill Advisory is a near certainty for much of remainder
of the area.

Will also need to address lake effect snow potential for that
same time frame with the NW mtns impacted the most, though looks
like a connection with Lake Huron could push potentially
advisory snows into the Laurels as well.

After that, focus turns to potential for a significant mixed
precip event centered around Monday/Mon night. QPF looks to be
around 0.25", but mixed precip/potential for freezing rain
(especially with very cold ground temps) could make this a
higher impact event.

&&

.AVIATION /07Z THURSDAY THROUGH MONDAY/...
As of Midnight, still VFR at LNS. Watching stronger radar
returns over the far southeast on the LWX radar, but low
levels are still quite dry, so no snow reported at LNS or MDT
yet.

Earlier discussion below.

Light wind and VFR flying expected through late this evening,
as central Pa remains under high pressure ridge between
approaching arctic cold front and developing coastal storm.

Snow from the coastal storm will overspread eastern Pa Thursday
morning. Latest model data indicates KMDT will be very close to
the western edge of the snow, so broadbrushed MVFR vis
reductions between 09Z-18Z. However, a period of IFR conditions
are possible during this time frame. Confidence in snow/vis
reductions is much higher at KLNS, where at least occasional IFR
conditions appear likely between 09Z-18Z. Further west, can not
rule out a period of light snow/reduced vis at KIPT Thursday
morning, but the odds are less than 50 pct. Elsewhere, the main
concern will be increasingly gusty northwest winds Thursday, as
the coastal storm strengthens rapidly off the New Jersey coast.
Bufkit soundings support frequent gusts between 30-40kts by
afternoon.

Outlook...

Fri-Sat...Gusty WNW winds. MVFR cigs/Scattered snow showers
western 1/3.

Sun...No sig wx expected.

Mon...Wintry mix possible.

&&

.CLIMATE...
December 2017 for Harrisburg was the 10th driest.
The 1.18 inches of precipitation was lower than the
1.27 inches that fell in December 1989. The driest
December on record was .23 inches in 1955.

December 2017 for Williamsport was just short of
being the 10th driest on record. The 1.19 inches of
precipitation that fell was just above the 1.17
inches that fell in 1947. The driest December on
record was .63 inches in 1928.
