1253 am est Mon dec 11 2017

Synopsis
Weak low pressure will pass by well to our north tonight,
followed by high pressure on Monday. A stronger low will also
pass by to the north on Tuesday. The associated cold front will
usher in very cold air for Tuesday night and Wednesday. Another
weak low may cross the area on Thursday or Friday, followed by
high pressure and more moderate temperatures heading into next
weekend.

Near term until 6 am this morning
12:30 am update: made a few minor tweaks to winds and sky cover
overnight and generally increased temperatures by a degree or so
across the area. Otherwise, the forecast is doing fine. Starting
to see a couple of light snow observations in the far
northwestern cwa, but anything more than flurries or a dusting
looks highly unlikely. No changes to pops wx grids at this time.

Previous discussion...

cloudiness will increase tonight ahead of a stout mid-level
shortwave and accompanying surface trough. Deeper columnar
moisture should be confined from the lehigh valley and southern
poconos in pa eastward into northern nj. There will be
sufficient lift for the development of precip, but it's expected
to be spotty and light. A few snow showers have already
developed in the berks and western chester area, but no
accumulation is expected with these showers, only flurries. With
the mid and upper levels saturated with respect to ice, and the
atmosphere at or below freezing, snow will be the primary
precip type. The fast movement of this system gives the
aforementioned area a 3-5 hour window for some spotty, light
snowfall. Snow ratios are 10-12:1 and only expecting up to
several hundredths of an inch of qpf, so a dusting to a half
inch is possible, generally from sussex county nj southwestward
into berks county pa. Cannot rule out isolated one inch amount
amounts, especially the southern poconos.

Given the expectation of a potentially bigger event (see long term
section below), the snowfall map on our website remains centered on
that event, and does not reflect any accumulation whatsoever for
tonight. Tonight's snowfall expectations are far short of advisory
criteria. Therefore it will be highlighted in the hwo, and if need
be, handled with a special weather statement (sps). We held off on
issuing a sps for now, given some uncertainty in the temporal and
spatial extent of the event.

Short term 6 am this morning through 6 pm today
Any snow showers are expected to wrap up by sunrise. Gradual
clearing will take place from west to east during the morning,
with additional stratocumulus cloud development during the
afternoon, especially northwest of the fall line. Temperatures
will be a few degrees warmer compared to Sunday, but still below
average. In addition, the airmass will be more stable, so
westerly wind gusts will be capped around 15 mph.

Long term tonight through Sunday
The extended forecast period features a continuing large- scale
trof over the eastern us, although the trof is forecast to
become much flatter toward the end of the week and into next
weekend. There will be a number of shortwv trofs rotating more
or less rapidly through the main trof, with associated surface
lows and frontal systems. Timing of the shortwaves becomes more
doubtful at longer ranges. Also, their rapid movement means
limited access to moisture and precip production.

One of the more potent systems is forecast to approach the mid-
atlantic Monday night and then move through the area on Tuesday. Low
pressure is forecast to intensify as it moves past to the north into
new england, and its associated very strong cold front will cross
the area on Tuesday afternoon. Ahead of the front Monday night into
Tuesday morning, a broad area of UVV is forecast to develop, likely
leading to some light precip. P-type is an issue, with mostly snow
over the poconos and lehigh valley, but a mixed bag or just rain
farther S e. 2 to 3 inches of snow could accumulate in the poconos.

All precip will change to snow by late Tuesday as cold air blasts in.

Tuesday night through Wednesday night will be dominated by very
gusty NW winds and strong caa, as the deepening surface low moves
slowly NE through new england and into canada. Wind chills in the
teens and single digits are likely.

A clipper type system is expected to pass near the mid_atlantic
sometime thu-fri, although the timing and track are rather uncertain
at this time. This system could bring some light snow to the area,
as temperatures are forecast to remain quite cold.

Current guidance suggests a moderating temperature trend for next
weekend with temps perhaps returning to near normal.

Aviation 06z Monday through Friday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Tonight... GenerallyVFR with CIGS around above 5000 feet
(sitting around 10 kft currently but a slight lowering is likely
before clouds scatter out near after daybreak). Some flurries
are possible, especially at rdg abe ttn, but little in the way
of impacts is expected. Winds generally light southwest. High
confidence.

Monday...VFR with west winds 5 to 15 kts. High confidence.

Outlook...

Monday night... Sub-vfr conditions possible, especially north of
phl, with a wintry mix of precipitation possible. Winds
generally light and predominantly southerly. Low confidence.

Tuesday... Sub-vfr conditions possible, especially early in the
day, with wintry mix possible generally north of phl. Winds
becoming west and increasing to 15 to 25 kts with higher gusts
after cold frontal passage. Confidence medium in general
evolution but low on timing.

Tuesday night and Wednesday... GenerallyVFR with very strong
west to northwest winds likely. Speeds 15 to 25 kts with gusts
to 40 kts possible. Medium confidence.

Thursday and Friday... GenerallyVFR but local MVFR possible in
rain or snow showers. West to southwest winds 5 to 15 kts with
potentially higher gusts. Medium confidence.

Marine
Winds remain near or just above advisory criteria on the
atlantic waters, so the small craft advisory was not changed
with this update. Gusts are near criteria on lower delaware bay,
but given the overall downward trend expected for the rest of
tonight, decided not to issue anything here for now.

Another advisory will be needed after midnight Monday
night Tuesday morning for all of the waters, but will let the
current advisory play out before issuing another one.

Outlook...

Monday night and Tuesday... Generally sub-sca conditions Monday
night, but advisory conditions likely by Tuesday as southwest
winds increase and seas build. After cold frontal passage late
on Tuesday, winds will switch to west or northwest and become
quite strong.

Tuesday night and Wednesday... Gale-force west or northwest winds
quite probable.

Wednesday night... Residual gale conditions becoming advisory-
level conditions during this period.

Thursday and Friday... Sub-advisory conditions are forecast at
this time.

Phi watches warnings advisories
Pa... None.

Nj... None.

De... None.

Md... None.

Marine... Small craft advisory until 6 am est early this morning for
anz450>455.
