What forecasters said that day

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

NWS Philadelphia/Mount Holly wrote its last area forecast discussion before this winter weather advisory went out at Feb 11, 12:16 AM EST, 3 hours 42 minutes earlier.

Area forecast discussion, Feb 11, 12:16 AM EST, 3 hours 42 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
1216 AM EST Sat Feb 11 2017

.SYNOPSIS...
A warm front will lift north of the area tonight into early
Saturday, while a clipper low will move across the Northeast
Saturday and push a frontal boundary just south of the area. A
stronger low will move across our area Sunday, pulling a frontal
boundary across the East Coast. This low will strengthen
significantly as it moves to our northeast and into the Gulf of
Maine Sunday night into Monday. As high pressure builds to our
south Tuesday, another low pressure system is expected to move
across the Northeast Tuesday night into Wednesday, then
strengthen as it moves into the Canadian Maritimes through
Thursday.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
High pressure will continue to move further off shore overnight
while a warm front will lift through our region overnight.

Snow showers are sliding northeast and are just about to exit
our region. However, did not make any adjustments to the PoPs at
this time as there could be additional snow shower development
across the northern half of our area as a mid level jet slides
closer.

The cloud cover and the warm front should prevent temperatures
from falling much tonight. Minimum temperatures are forecast to
occur this evening. Readings should begin to rise slowly with
the arrival of the warm front.

A light southwest wind early this evening should become south
to southeast for a time overnight before shifting back to the
southwest in the wake of the warm front.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/...
The warm front may drop back into parts of eastern Pennsylvania
and northern New Jersey as a cold front on Saturday. We are
anticipating a fair amount of cloud cover but no precipitation.

The wind should favor the southwest to west at 5 to 10 MPH to
the south of the frontal boundary. The wind may become somewhat
variable to the north of the front.

Maximum temperatures are forecast to range from around 40
degrees in the elevated terrain of the Poconos and northwestern
New Jersey to near 60 in southern Delaware.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
On Saturday night, an area of low pressure will be moving
through the Ohio River Valley as it moves along the frontal
boundary that sinks across the area during the day Saturday. The
low is expected to move across our area during the day Sunday,
which will be the most likely period for precipitation. However,
there will be enhanced moisture and lift associated with a lead
short wave/vorticity impulse increasing Saturday night, so
precipitation could start during the pre-dawn hours Sunday.
Temperatures are expected to cool some overnight Saturday,
especially for portions of northern New Jersey and northwest
Pennsylvania where temperatures are likely to drop below
freezing by the time the precipitation begins. This is expected
to lead to a period of sleet and freezing rain across areas
along and north of the I-80 corridor. Once the cold air sets in,
it may be hard to scour out for the higher elevation of Monroe,
PA and Sussex, NJ. These icy conditions could lead to slippery
travel conditions Sunday. The remainder of the forecast area is
expected to remain all rain. The precipitation could change over
to snow late in the afternoon and evening as cold air through
the column moves in as the low passes to our northeast.

As the low passes to our northeast Sunday night and Monday, it
will strengthen quite significantly, especially as it moves into
the Gulf of Maine. Winds are expected to increase and become
quite gusty late Sunday night and during the day Monday. Winds
gusts could reach 40-50 mph. A Wind Advisory may be needed for
portions of the area as we move through the weekend. With the
strong northwest flow, it will not be surprising to see some
flurries or snow showers across the Poconos during the day
Monday.

High pressure builds to our south late Monday night into early
Tuesday, but our area will be on the far northern edge. Still we
expect quiet weather Monday night into Tuesday.

For Tuesday night into Wednesday, another clipper system is
forecast to be moving out of the Great Lakes region and
approaching our area. The 12z GFS and ECMWF differ in how they
react to the low as it moves offshore with the GFS absorbing it
into the low already located across the Canadian Maritimes. The
ECMWF brings another low northward from the southeast coast and
strengthens the two as they combine off the coast then move
northeastward into the Canadian Maritimes. The GFS actually has
this low off the southeast coast, but not until 12 hours later.
Regardless, there will be a chance of showers Tuesday night into
Wednesday as the clipper low approaches and moves across the
area. If the precipitation starts early enough, it will begin as
snow for most places, then possibly mix with or change to rain
during the day Wednesday. Not much changed with the model
guidance since yesterday, so with the uncertainty and
disagreement between the two, we will follow closely to WPC
during this period.

&&

.AVIATION /05Z SATURDAY THROUGH WEDNESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.

For the 06Z TAFs...VFR conditions expected today with a BKN-OVC
midlevel cloud deck waffling between 8-15 kft through the day.
May see a SCT to possibly BKN lower-level stratocumulus deck
around 3000-5000 ft late this morning and afternoon, but latest
model guidance has come fairly dry in this layer. Light
southwest to west winds should develop across the region. By
this evening, lower cloud deck more likely to become
established, with ceilings approaching MVFR by 06Z Sunday. Some
indications a front will move in from the north, which would
switch (light) winds to northeast and promote a much more rapid
deterioration of ceilings/visibility. Confidence is low
regarding timing/occurrence.

OUTLOOK...

Saturday night...VFR possible early, lowering to MVFR and IFR
overnight. Rain possibly moving in late overnight. Freezing
rain/sleet expected to remain north of TAF sites.

Sunday...IFR conditions with periods of rain. Freezing
rain/sleet expected to remain north of TAF sites.

Sunday night...Conditions improving overnight. Rain may change
to snow during the evening before ending. Winds becoming gusty
northwest 30-35 knots.

Monday-Monday night...Generally VFR. Strong gusty northwest
winds 30- 40 knots. Wind gusts diminishing overnight.

Tuesday-Wednesday...Generally VFR. Chance of rain or snow
showers which may periodically lower conditions. Northwest winds
could become gusty 25-30 knots on Wednesday.

&&

.MARINE...
Increasing southwest flow tonight should result in wind gusts
building back into the 25 to 30 knot range on our ocean waters
late this evening. Thus the small craft advisory continues
through 1 PM Saturday.

OUTLOOK...

Saturday night-Sunday...Sub-Small Craft Advisory conditions expected.

Sunday night-Monday night...Return to Small Craft Advisory
conditions likely in the evening, increasing to gale force
overnight Sunday through Monday. Conditions may fall back to
Small Craft Advisory levels Monday night.

Tuesday...Conditions expected to fall below Small Craft Advisory
levels during the day Tuesday.

Tuesday night-Wednesday...Conditions may increase back to Small
Craft Advisory levels overnight Tuesday into Wednesday.
