...THE URBAN AND SMALL STREAM FLOOD ADVISORY REMAINS IN EFFECT UNTIL
330 AM EST FOR MORRIS...SUSSEX...WARREN...BERKS...LEHIGH...CARBON...
MONROE AND NORTHAMPTON COUNTIES...

At 1154 PM EST, several river and stream gauges in the advisory area 
were rising as a result of earlier heavy rainfall. Though the 
heaviest rainfall has ended, runoff will continue to produce rises 
on small creeks and streams, especially in northern New Jersey, 
where the heaviest rainfall has occurred and where antecedent 
conditions are especially wet. 

Some locations that could experience flooding include...
Allentown, Reading, Easton, Hazleton, Morristown, Port Jervis,
Newton, Lehighton, Montague, Mount Pocono, Bethlehem, Dover, Madison,
Hopatcong, Forks, Florham Park, Emmaus, East Hanover, Wyomissing and
Kinnelon.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Be especially cautious at night when it is harder to recognize the
dangers of flooding.

A Flood Advisory means river or stream flows are elevated, or ponding
of water in urban or other areas is occurring or is imminent.

Area Forecast Discussion
National Weather Service Mount Holly NJ
942 PM EST Mon Dec 31 2018

.SYNOPSIS...
Low pressure tracks across the eastern Great Lakes tonight, then
across northern New England into the Canadian Maritimes during
Tuesday. An associated cold front moves across our area Tuesday
morning. High pressure builds in later Tuesday night and Wednesday
before shifting offshore Thursday. Low pressure in the Tennessee and
Ohio Valleys Thursday into Friday moves across the Mid-Atlantic late
Friday into Saturday before moving offshore during Saturday. High
pressure then builds in from the west and south Sunday into Monday,
however a front may settle in from the north later Sunday.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
An area of low pressure will move through the eastern Great Lakes
region tonight, while high pressure offshore of New England
continues to drift out to sea. A warm front associated with the low
pressure system near the Great Lakes region has lifted north
into the southern part of our area as of this hour. A couple
more periods of rain will continue to move across the area
overnight as several short wave/vorticity impulses will move
across the area. Each of these waves will have some enhanced
lift associated with them, but there will also be a few periods
of rain- free weather in- between. Storm total rainfall amounts
area about 1.00-1.25 inches across northeast Pennsylvania and
northern New Jersey; to 0.75-1.00 inches for southeast
Pennsylvania, central/southern New Jersey, and northern Delaware
and Maryland; to 0.25-0.5 for far southern New Jersey and
central and southern Delaware and Maryland.

The rain is expected to taper off during the overnight hours through
daybreak as the moisture and lift associated with the last short
wave move east of the area.

Temperatures are well above freezing, and will actually rise through
the night, so there will be no P-type issues.

East to southeast winds this evening around 5-10 mph will shift to
the south and southwest later tonight and increase in speed to 10-20
mph, and become gusty 20-25 mph toward daybreak.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/...
A strong cold front will sweep across the area during the morning
hours Tuesday, while low pressure moves across New England. While
the front is expected to be dry with its passage, it will bring very
gusty winds with it as a tight pressure gradient will be in place.
Very strong winds aloft of 40-50 knots within the lowest 2,000 feet
will likely carry down to the surface as strong mixing develops
along and behind the front. This is expected to produce wind gusts
of 45-50 mph for a period during morning hours Tuesday, mainly
between 8-11 am. Winds will remain gusty through the day, but will
subside as the day progresses. So we ring in the New Year with a
Wind Advisory for all of our areas. Temperatures are going to
continue to be quite warm on Tuesday, 20+ degrees above normal for
the daytime high, although it will feel cooler with the gusty winds,
especially later in the day as temperatures drop.

&&

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
Summary...Another rain event for the end of the weak into the
weekend with potentially milder air, then some cooling later in the
weekend and early next week.

Synoptic Overview...Active northern and southern streams continue,
and we start with a more zonal flow across the East. This will turn
more cyclonic in the Northeast later Wednesday and Thursday as a
short wave trough amplifies some. Meanwhile, a deep closed low
across the southern Plains to start Thursday tracks east-
northeastward into the weekend. This will drive surface low pressure
into the Mid-Atlantic region. While there is still some timing
differences, there seems to be a better consensus with the evolution
of the deep closed low moving across the South which then lifts into
the Mid-Atlantic and off the Atlantic coast by this weekend. The GFS
has been shifting towards a slower/deeper solution which has
continually been depicted by both the ECMWF and UKMET the past few
days. The CMC and GFS-FV3 continues to be on the fastest side of the
guidance. Comparing the ensembles continues to show a trend towards
a slower progression, therefore the updated forecast reflects a
slightly slower system. Following the closed low, the pattern looks
to be more of an upper-level trough in eastern Canada and the
Northeast over the weekend into early next week.

For Tuesday night and Wednesday...The flow starts out more zonal in
the East, however a short wave trough amplifying some across the
Great Lakes will shift eastward and move into the Northeast later
Wednesday night. Meanwhile, a strong closed low ejects into the
southern Plains late Wednesday with plenty of moisture advecting
north and east well ahead of it. Surface high pressure across the
area will shift east during Wednesday, and this should supply plenty
of dry low-level air. The forecast challenge is the interaction
between front-runner short wave energy and moisture with the
southern stream and the short wave trough moving into the Northeast.
Some guidance is more robust with this while others indicate less
(drier solutions). There appears to be a short window of opportunity
for the southern moisture to get pulled north into at least part of
our region as the energy quickly shifts to our east, however enough
dry low-level air may prevent much from occurring. Precipitation
types favor snow showers across the north, rain/snow showers
southward with just rain farther south. Given the uncertainty with
how much precipitation will occur, kept the PoPs at slight chance
starting later Wednesday night.

For Thursday and Friday...The aformentioned northern and southern
stream interaction will determine how much precipitation occurs
Thursday morning, however there should be a break as weak high
pressure arrives while a strong closed low lifts east-northeast
during this time frame. The consensus of the guidance is for a
slower eastward progression, especially given the depth of the
closed low. Plenty of moisture surging northward will allow rain to
overspread the area during Friday, however the timing of this will
be key as dry enough low-level air could result in a wintry mix
across the northern areas at the onset. The surface low looks to
move right across our area Friday night with periods of rain
continuing, the extent of the warming at the surface will depend on
the exact track of the surface low as this will determine how far
north the warm sector gets. The deeper moisture plume may shift
offshore later Friday, potentially resulting in a lessening of the
rain intensity.

For Saturday through Monday night...Low pressure continues to
move across our area during the day Saturday. Any mixed precipitation
across the northern portions of the area should changeover to
all rain through the day Saturday. Highs range from near 40 across
the higher terrain to the north to low 50s across southern Delaware.
Rain should move out of the area to our northeast Saturday night,
leading to a quieter, yet short- lived remainder of the weekend.
Lows look to sit in the mid 20s to upper 30s from north to south
across the area Saturday night.

Dry weather settles into the region as high pressure moves across
the area Sunday into Monday. Highs in the mid 30s across the Poconos
to near 50 across southern Delmarva. The quiet weather quickly comes
to a close as the next storm system looks to move into the region
Tuesday. Significant model disagreement exits in terms of timing, so
went with a middle-of-the-road approach, taking a blend. At this
point some snow showers are possible across the northern portions of
the area, but will need to monitor the system as time progresses.

&&

.AVIATION /03Z TUESDAY THROUGH SATURDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Tonight...All sites have fallen to IFR as of this hour and will
remain at these conditions through the overnight hours before
possible improvement to MVFR toward daybreak.

Winds will remain out of the east to southeast through for a few
more hours north of an approaching warm front, then shift to
the south to southwest once the warm front lifts across the
area. This southerly shift has already occurred at MIV and ACY.
Speeds will be 5-10 knots early, before becoming 10-15 knots
overnight. Gusts of 15-20 knots will begin late in the night and
toward daybreak.

Low-level Wind shear will develop tonight as strong winds aloft
move across the area, and will continue through much of the
overnight period until wind gusts develop.

Tuesday...MVFR conditions will begin the day across the area, before
an improvement to VFR later in the morning into the afternoon. With
the west to northwest flow developing behind a cold front, a layer
of stratocumulus clouds may remain across the area through the day.

Winds will increase with the passage of the cold front and become
quite gusty. Winds are expected to gust 30-35 knots, with some peak
gusts expected around 40 knots. The wind gusts will diminish as the
day progresses.

OUTLOOK...
Tuesday night...VFR. Northwest winds diminishing to 10 knots or less.

Wednesday and Thursday...VFR with possibly some MVFR conditions
developing Wednesday night into Thursday along with some showers.
Some improvement may occur Thursday afternoon, however conditions
should lower again later Thursday night with the potential for some
rain arriving. The timing is less certain. Northwest winds 5-10
knots, becoming light and variable Wednesday afternoon through
Thursday.

Friday and Saturday...Periods of rain probable with conditions
lowering to MVFR and IFR. Southerly winds mainly 10 knots or
less.

&&

.MARINE...
Tonight...Winds across the waters will increase this evening to 25-
30 knots north of a lifting warm front. However, once the warm front
lifts northward, strong winds are expected to develop across the
waters and likely reach gale force everywhere. So the Gale Warning
continues for the waters adjacent to New Jersey, and has been
expanded for the remainder of the area during the overnight hours.
Winds are especially likely to begin gusting as a cold front sweeps
across the area Tuesday morning and reach 35-40 knots. The wind
gusts will diminish through the day Tuesday, so we keep the end time
of noon for all areas.

OUTLOOK...
Tuesday night through Friday...Winds and seas drop below Small Craft
Advisory to start Tuesday evening, otherwise the conditions are
expected to be below advisory criteria.

Saturday...Sub-Small Craft Advisory conditions are anticipated.
