NWS Philadelphia/Mount Holly wrote its last area forecast discussion before this areal flood warning went out at Dec 21, 4:15 PM EST, 52 minutes earlier.

Area forecast discussion, Dec 21, 4:15 PM EST, 52 minutes before
Area Forecast Discussion
National Weather Service Mount Holly NJ
415 PM EST Fri Dec 21 2018

.SYNOPSIS...
Low pressure over the Appalachians will lift to the north and east
and into eastern Canada tonight. A cold front will cross the region
Saturday morning, then high pressure builds south of the region
through Sunday. A weak clipper system passes through the region
Sunday night, followed by a weaker system Tuesday night. High
pressure returns for the middle of next week. Another storm system
looks to affect the East Coast by the end of next week.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...
As of mid to late afternoon a large amplitude upper trof
remains to our west, with a 120+ kt upper jet streaking up the
east side of the trof and gradually shifting east across the mid
Atlantic region. Also, more or less coincident with the jet, a
pronounced mid/upper- level dry slot is noted on the water vapor
imagery across our area, which has effectively ended our precip
for now. However an axis of surface based instability has
developed from central NC/VA northward across central PA, and
this axis is supporting scattered convection with lightning
noted along the west edge of the dry slot. The axis of surface
low pressure extends from roughly SW VA to eastern lake Ontario,
with SE winds continuing this afternoon over the PA/NJ and
Delmarva regions.

For tonight, the surface low and upper trof will lift NE across
NY state and into Canada. Behind the low, an associated and
fairly sharp cold front will sweep across the forecast area
between 06Z and 12Z Saturday morning. Some scattered showers may
occur overnight ahead of the frontal passage, most likely over
NW NJ, the Lehigh VLY and the Poconos. Our flood watch is
maintained for those areas, but has been cancelled elsewhere,
was no widespread heavy rain is expected. Temperatures will fall
rather sharply in the early morning hours behind the front, as
winds shift to the NW.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH 6 PM SATURDAY/...
On Saturday, the low pressure over Canada will continue to move
northeast and away from our region as a ridge of surface high
pressure begins to build in from the west. No precip is
expected, and altho some clouds may linger in the morning, a
general clearing trend is expected by afternoon. With cold
advection behind the front, temperatures will struggle to rise
more than a couple of degrees during the day. A fairly strong
pressure gradient and downward mixing of momentum will result in
gusty NW winds during the day.

&&

.LONG TERM /SATURDAY NIGHT THROUGH FRIDAY/...
Low pressure over eastern Canada continues to lift to the north
and east Saturday night. Meanwhile, high pressure centered
south of the region will slowly build east. Winds diminish in
the evening, and become nearly light and variable late, and
skies clear out. This sets up decent radiational cooling
conditions, and lows will drop into the 20s in outlying areas,
and in the low 30s in the urban corridor and in Delmarva. Quiet
conditions continue into Sunday with highs in the 40s.

Weak clipper system passes through the region Sunday
night/early Monday morning. Moisture will be limited, so
expecting less than 1/10" liquid QPF with this system. There may
be some ptype issues with it, depending on when the system
passes through. For now, looks like all snow for southern
Poconos and far NW NJ, and a rain/snow mix moving south from
northern NJ/Lehigh Valley down into the Delaware Valley and much
of southern NJ as night progresses and temperatures fall off.
Not much snow accumulation, generally less than an inch in
higher elevations of the southern Poconos, and not much
elsewhere. Lingering Lake Effect snow bands will develop over
western NY and western PA and light snow associated with these
bands may continue into Carbon and Monroe counties through
Monday afternoon. Otherwise, high pressure builds in from the
west behind the departing clipper for the rest of Christmas Eve
and Christmas Day. Highs generally in the 30s to low 40s on
Monday, and a few degrees cooler than that on Tuesday as CAA
filters into the region.

Another weak clipper system passes through Tuesday night.
Latest 12z guidance seems to have minimal QPF associated with
it. GFS is dry, and the ECMWF has only a few hundredths of an
inch of liquid QPF. CMC-GDPS also dry. Will not carry PoPs
Tuesday night, but will have scattered flurries with its
passage.

Elongated high pressure builds into the Northeast for the
midweek period. Conditions will be dry through Wednesday and
likely into much of the day Thursday. High pressure moves
offshore on Thursday.

The next storm system digs through the nation during this time.
Warm front lifts north through the region sometime Thursday
night. There are some model differences. 12z operational GFS is
faster than the 12z ECMWF and the 12z CMC-GDPS. Will cut back on
PoPs from model guidance, generally running with slight
chance/low chance late Thursday. PoPs then ramp up for Thursday
and Friday as low pressure passes north of the region.

Based on latest temperature guidance, think snow or a rain/snow
mix for the northern half of the forecast area, gradually
becoming all rain throughout as the day progresses on Friday.
Stay tuned.

&&

.AVIATION /21Z FRIDAY THROUGH WEDNESDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.

This afternoon and this evening...Very low-confidence forecast
with widely varying CIGs across the area. Low stratus is moving
in from the ocean/Delaware Bay to ILG/MIV/ACY this afternoon
and will likely affect the Philly terminals for a lengthy period
this afternoon. VSBYs near/below a quarter mile are possible at
ILG/ACY/MIV as well. Otherwise, variations from VFR to IFR
probable through the evening. Showers possible, but coverage
will be scattered and duration brief. South to southwest winds
around 10 kts.

Tonight...Gradual improvement to VFR may occur, although exact
timing is very uncertain. Winds becoming west around 10 kts,
perhaps gusting by dawn. Very low confidence.

Saturday...Mainly VFR with west to northwest winds 10 to 20 kts
with gusts to 30 kts. Moderate confidence.

OUTLOOK...

Saturday night...VFR. W-NW winds diminishing to less than 5 kt.

Sunday...VFR. SW winds 5-10 kt.

Sunday night through Monday morning...Scattered rain and/or
snow showers with brief sub-VFR conditions. SW winds 5-10 kt.

Monday afternoon through Wednesday...Generally VFR. NW winds
15-20 kt with gusts up to 30 kt on Monday, becoming NW 5-10 kt.
Scattered flurries possible Tuesday night.

&&

.MARINE...
Southeast winds are running around 15 kt this afternoon, but
seas remain elevated and a SCA continues in effect for all
forecast waters. Winds tonight will shift gradually to SSW and
then sharply to the west early Saturday morning. Gale force
gusts are expected to develop over the waters for several hours
during the day and thus a gale warning has been issued for
Saturday. Seas will also remain elevated in the 5 to 10 ft
range over the coastal waters.

OUTLOOK...

Saturday night through Sunday...SCA conditions continue. 25-30
kt gusts diminish Saturday night, then elevated seas continue
through Sunday.

Sunday night...Sub-SCA conditions.

Monday through Monday night...SCA conditions.

Tuesday through Wednesday...Sub-SCA conditions.

&&

.HYDROLOGY...

The steady rain has ended over and no further widespread heavy
rain is expected. Total amounts were generally in the 1 to 2
inch range, with some higher amounts noted is a few places,
mainly northern NJ and the Poconos. Some additional rainfall
from scattered showers is possible tonight, especially over the
Poconos, Lehigh Vly and NW NJ. Considering all this, the flood
watch has been cancelled for most of our forecast area, but it
continues until 100 am Saturday for our NW zones where
additional rain is more likely, as described above. All precip
should be over by around sunrise tomorrow morning.
