The episode as NWS PHI wrote it up.
An area of low pressure tracked up the east coast interacting with a cold front which lead to rapid development of a winter storm across the state. This storm quickly moved out by the 5th. However, snowfall accumulations and gusty winds occurred with the storm. Blizzard conditions occurred in Sussex county DE. A few gusts in New Castle and Sussex counties were around or over 50 mph during the afternoon and evening. A few dozen car crashes occurred. Local mail was delayed due to the storm. Severe cold continued for the next week leading to many locations going to code blue operations and closed the Cape May Lewes Ferry.

Area Forecast Discussion
National Weather Service Mount Holly NJ
443 AM EST Thu Jan 4 2018
.SYNOPSIS...
Low pressure rapidly intensifies as it quickly moves northward to
the Atlantic waters east of New Jersey this morning, then to
the Canadian Maritimes by Friday. Arctic high pressure will then
build into the East through most of the weekend. Low pressure
is forecast to track near our area early next week.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
4 AM update...
*Major winter storm to impact the region through today*
Rapidly deepening low pressure currently located east of north
Carolina and moving north. Bands of snow are pushing north into
forecast area and the snow has already been falling moderate at
times over southern Delaware and coastal NJ with lighter snow
falling farther N/W across PA. As we head into the day Thursday,
the low will continue to rapidly deepen as it moves NNE east of
the coastal waters. Expect strong forcing aloft at the jet
stream level to couple with mid level F-Gen forcing to produce
bands of moderate to heavy precipitation at times over eastern
areas which will fall mainly as heavy snow...though a little
sleet could mix in at times this morning right near the New
Jersey shore. There is still some question just how far west
the moderate to heavy precipitation will extend with the HRRR
generally being drier to the west back toward I-95 compared to
the other high res guidance. We continued to stay with a
consensus approach which is supported by the latest
mesoanalysis and trends and overall, no major changes to the
forecast with this update. Expect snow, moderate to heavy at
times from I-95 east, this morning as the storm draws closer and
bands rotate back to the west. These are the areas that remain
under Winter Storm Warnings and Blizzard Warnings and the snow
could fall at 1 to 2 inches per hour at times here this morning.
Farther west, snow will be lighter from Chester Co. PA north to
the southern Poconos and far NW New Jersey as we don't expect
the heavier bands to make it this far north and west. Again, the
main forecast challenge right now is right along the I-95
corridor itself since this area will be near the edge of the
heaviest bands. Generally expect 4 to 8 inches in this area but
it will be more if heavier bands make it farther west. Farther
east expect 8 to 12 inches with locally up to 14 inches
possible.
Heading into this afternoon, as the storm pulls north of our
latitude to a point east of Long Island the snow will taper off
west to east. However the other main story will be the winds.
Winds increase through this morning and by later this afternoon
expect NW winds generally 25 to 35 gusting 40 to 50 mph. This
will create significant blowing and drifting snow along with
poor visibilities and very poor travel conditions through this
afternoon even after the snow ends.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM FRIDAY/...
The falling snow will be done by tonight but very strong winds
and falling temperatures will be a big issue and continue to
create high impacts with blowing/drifting snow and bitter wind
chills. Most of our eastern PA zones are under a Wind Chill
Advisory with a Wind Chill Warning in effect for Carbon and
Monroe Counties. By Friday morning expect lows generally ranging
from around zero to 10 above with wind Chills ranging from 5 to
25 below zero!
&&
.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
NO CHANGE in forecast philosophy. This is a very rugged period
of cold weather for our area...not often experienced. See
climate section.
Have not changed this discussion from previously issued 330 PM
ydy.
What we changed in this forecast from the previous forecast...lowered
temps a few degrees Fri night-Monday evening per 2m temps from
the 00z/4 GFS/EC/GGEM, increased wind gusts and lowered wind
chills a bit. Therefore have issued wind chill advy and warnings
where we KNOW it will occur or be within 2F of threshold. se NJ
and Delmarva are less certain on wind chill and future
forecasts will address. Also delayed onset of the next waa
event. Note: no guarantee the temp rises above Freezing Monday
and we may be facing a winter wx advisory situation Monday
night.
We continue to advise everyone to take this upcoming Friday-Sunday
frigid outbreak very seriously. Have safety plans in place
including a stash of warm clothes in the car in case of a rural
location break down and certainly plenty of fuel for well
maintained home and facility heating systems.
Summary...Dangerous cold in the wake of the Nor'easter through
at least the first half of the weekend; a warm-up early next
week as low pressure tracks near our area.
Synoptic Overview...A deep upper-level trough in the East weakens
and shifts offshore Saturday night and Sunday. The flow then backs
ahead of the next trough sliding across the Midwest to the Southern
Plains. This combined with a return flow on the backside of
departing cold high pressure will allow the arctic air to start
eroding. Warming takes place early next week as a low pressure
system tracks near our area, however a more southern track may keep
colder low-level air in longer especially north and west of I-95.
For Thursday night through Sunday...Intense low pressure will be
moving into the Canadian Maritimes Thursday night into Friday. This
time frame will be dominated by arctic air and dangerous cold. Some
moderation is expected Sunday though as the major upper-level trough
lifts out. Until then, gusty northwesterly winds will combine with
very cold air temperatures leading to dangerously low wind chills
across the entire area. The gusty winds may continue blowing and
drifting snow into Friday. There is a Wind Chill Watch for the
southern Poconos for Thursday night into Friday. Some areas in this
region are forecast to experience wind chills right around -25F at
times. For now, we will keep the Watch going. Elsewhere, a Wind
Chill Advisory looks to be needed for Thursday night and Friday
morning with wind chills down around -10F. Additional Wind Chill
Advisories will probably be needed for Friday night and Saturday
night. The extent of this will depend on how much the winds stay up,
although it will be so cold just light winds will have an impact on
the wind chill. Overall, a very very cold time frame followed by
some improvement on Sunday as the arctic high starts to shift
offshore.
For Monday through Wednesday...As the flow initially backs ahead of
the next system, warm air advection occurs as high pressure is to
our east. Low pressure is forecast to track near our area with a
cold front moving through Monday night. Some guidance however is
farther south with the primary surface low development, and if this
occurs the warming would be slowed especially in the low levels.
This could result in a period of some mixed/icy precipitation to
then even some rain as enough warming should take place. More
specifics as we get closer. It then look to turn colder for
Wednesday.
&&
.AVIATION /10Z THURSDAY THROUGH MONDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.
Today...Snow with IFR conditions (LIFR at times within heavier
snow where hourly rates could be 1-2 inches) to nearly all
terminals. The snow will end from southwest to northeast during
the afternoon. North to northwest winds increase to 15-25 knots
with gusts 30-40 knots resulting in considerable blowing and
drifting snow. The ceilings/visibilities should improve by later
in the afternoon. Moderate confidence.
Tonight...VFR but strong winds will continue to create areas of
blowing snow.
OUTLOOK...
Friday through Saturday...VFR with northwest winds 10-20 knots
with gusts 25-35 knots. Isolated 40-45 kt gusts possible
Friday afternoon! High confidence.
Sunday...VFR with west to southwest winds less than 10 knots. High
confidence.
Monday...MVFR conditions possible with a chance for some mixed
precipitation at night. Southwesterly winds 5-10 knots. Moderate
confidence.
&&
.MARINE...
Winds and seas continue to ramp up as the storm approaches.
Expect Storm Force Winds over the ocean waters and the southern
Delaware Bay today with seas building to 10 to 14 feet over the
ocean and up to 7 feet over the Bay. In addition, visibilities
will be reduced in heavy snow and rain.
The snow and rain will have moved out by tonight but very strong
NW winds at at least Gale Force persist along with falling
temperatures so freezing spray will be a big issue once again.
Outlook... Friday through Saturday...Gale conditions through
the period, with moderate to heavy freezing spray (especially
near the coast) developing and advisories and warnings are now
issued for same. Gale warnings will be needed after the Storm
Warning expires for the Atlantic Delaware waters and is already
in effect for Delaware Bay and the New Jersey coastal waters
through Friday night. Low end gales may occur for a time
Saturday. There is high confidence in gales through at least
Saturday and in freezing spray being an increasingly hazardous
threat.
Saturday night...Small craft advisory conditions are forecast, with
light to moderate freezing spray.
Sunday and Monday...Sub-advisory conditions area anticipated.
&&
.TIDES/COASTAL FLOODING...
Coastal Flood Advisories are in place for the NJ and DE
coastlines for this mornings high tide.
The rapidly intensifying cyclone off the coast and the recent
full moon, has increased the potential for coastal flooding for
this mornings high tide. This mornings forecasts continue to
show widespread minor tidal flooding along the NJ and DE coasts
with a couple locations on the upper end of minor. Current
guidance keeps flooding below moderate thresholds but we will
continue to monitor this as we head towards this mornings high
tide.
Reports from the Manasquan area on Wednesday indicated water
reaching portions of low-water crossings and subsequently
freezing. Any stagnant water at high tide has the potential to
freeze, creating an additional impact to the potential for
flooding.
Additionally, as the storm pulls away we will see very strong
westerly winds across the region and there will be the
potential for blowout tides to occur between Friday and Sunday.
&&
.CLIMATE...
Record snowfall for today January 4 and most locations should
exceed this daily record!
ACY...2.5-1905
PHL...4.5-1942
ILG...3.5-1952
ABE...6.5-1942
Arctic cold will continue its hold on the region through Monday
morning with what we think will be increasing adverse impact on the
infrastructure as one of the most persistent cold outbreaks in
recent memory extends through Sunday January 7.
This outbreak has already been associated with several daily cold
(both maximum and minimum) temperature records over the past week,
including a record low at Georgetown, DE (GED) and Reading, PA (RDG)
and a record cold maximum at Allentown (ABE) on New Years Day. On
the 3rd...we had a record low at GED and a record equaling low at
RDG.
Additional record lows and record cold maximum temperatures should
be set Friday, Saturday and Sunday.
The following list includes records, many of which will be
rewritten.
Record Low Temps for Friday 1/5: also Record low Max
Allentown (ABE).....not likely 15F (1968)
Reading (RDG).......not likely 12F (1904)
Atlantic City (ACY).not likely 18F (1968)
Philadelphia (PHL)..not likely 14F (1904)
Wilmington (ILG)....not likely 16F (1904)
Trenton (TTN).......not likely no rer avbl
Georgetown (GED)....9F (1958) no rer avbl
Mount Pocono (MPO)..not likely no rer avbl
Record Low Temps for Saturday 1/6: also Record low Max
Allentown (ABE).......not likely 13F (1942)
Reading (RDG).........not likely 15F (1912)
Atlantic City (ACY)...4F (1981) 17F (1912)

Wilmington (ILG)...7F (1924 and 1946) 20F (1988)
Trenton (TTN)...5F (1896 and 1904) no rer avbl
Georgetown (GED)...6F (1969) no rer avbl
Mount Pocono (MPO).....not likely no rer avbl
Record Low Temperatures for Sunday 1/7:
Allentown (ABE)....-4F (1942)
Atlantic City (ACY).4F (1884)
Philadelphia (PHL)..4F (2014)
Wilmington (ILG)....3F (2014)
Reading (RDG).......0F (2014)
Trenton (TTN).......2F (2014)
Georgetown (GED)....8F (2014)
Mount Pocono (MPO)..-8F (2014)
Some uncertainty exists as to when the temperature will exceed 32F
early next week but for now our forecast is that this will occur
Monday.
So, since odds strongly favor temps maintaining aob 32F through
Sunday Jan 7...here is a perspective on how this will rank in our
official records.
Leading with the following: In a short 20 year period of accessible
history...Mount Pocono has never recorded a complete single day of
subzero temps. It has only 2 consecutive days of max temps sub 10F.
There is a good chance Mount Pocono will remain at or below zero
from about 7 PM Friday through about 10 AM Sunday. That will also
include some wind chill of 30 below.
At or below freezing consecutive days listing below with no change
from yesterday except PHL listed last.
ABE 13 consecutive days would be ranking 4th longest (tied) and
coldest since February 1979. The last time ABE was above freezing
was 1835z/25th=135PM EST.
RDG 13 consecutive days would be ranking 7th longest and coldest
since December 2000. the last time RDG was above freezing was
1855z/25th=155PM EST. (This data is from our XMACIS; Our climate
binder has this as 8th longest).
TTN 13 consecutive days would be ranking 4th longest and coldest
since February 1979. The last time TTN was above freezing was
2120z/25=420PM EST.
ILG 12 consecutive days would be ranking 3rd longest (tied) and
coldest since February 1979. The last time ILG was above freezing
was 2051z/26=351PM EST.
ACY (shaky and uncertain based on what happens this afternoon and
tonight) 12 consecutive days would be ranking 5th longest and
coldest since February 1979. The last time ACY was above freezing
was 2125z/26=425PM EST.
Max temps at all locations listed for 12-13 consecutive day 32F or
less max temps made it through Wednesday January 3 except PHL which
rose to 33F for a couple of minutes at 337 PM January 3rd. That
particular couple of minutes above freezing officially makes it a
discontinuous 12-13 day string of 32F or less, but for all intents
and purposes...it marginally affects the ranking of coldest periods.
PHL recalculated below for 33F or lower.
PHL 12 consecutive days (33F or lower) would be ranking 8th longest
(tied) and coldest such period since January 1982.
