Area Forecast Discussion
National Weather Service Mount Holly NJ
327 AM EST Thu Nov 14 2019

.SYNOPSIS...
Strong high pressure centered across New England this morning
extends down into the Mid-Atlantic, will then shift eastward through
tonight. A cold front will move through late Friday, then high
pressure builds into our area from the northwest and north later
Saturday and Sunday before shifting into the Canadian Maritimes. An
ocean storm develops off the Southeast coast Friday night and slowly
moves northeastward over the weekend and remaining well off of our
coasts, then another storm may develop off the Carolina coast
Tuesday and take a similar track through Wednesday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Elongated high pressure extending from New England down to the Mid-
Atlantic will continue to lift to the northeast and move offshore
today. Meanwhile, H5 trough with several embedded shortwaves moves
through the Great Lakes and Ohio Valley.

With the high lifting away, light south to southwest flow develops.
Surface dewpoints will creep up into the teens and 20s, However, it
remains quite dry across the region, so only expected SCT-BKN cirrus
throughout the day with the approach of those shortwaves.

For the morning commute, still cold, but with not much wind, the
wind chill will not be as low as it was Wednesday morning. There are
some high clouds building in from the west, and this should help
hold temps steady generally in the 20s, but there may be some spots
where there is no cloud cover where temps will fall into the teens.

WAA on tap for today, and highs will be about 10 degrees higher than
Wednesday, topping off in the mid 30s in the southern Poconos, and
in the lower 40s north and west of the Fall Line. Highs will be in
the upper 40s to around 50 elsewhere.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM FRIDAY/...
Upper trough digging through the Midwest and moving into the Eastern
Seaboard will begin to cut off a closed upper low over the
Mississippi and Tennessee Valleys. Out ahead of that upper low,
surface low pressure begins to develop off the Southeast U.S. coast.
A frontal boundary develops along the Eastern Seaboard, and the low
will begin to lift along that boundary well after midnight tonight.

In terms of sensible weather, conditions should be dry for most of
the night, but clouds across the northern zones will move offshore,
and clouds will move into the southern portions of the forecast area
associated with the approach of the surface low approaching the Mid-
Atlantic.

After midnight and into the pre-dawn hours of Friday, some precip
will develop off the southeast New Jersey coast and into Delmarva.
Precip should be mostly rain mainly south and east of the Garden
State Parkway and across most of southern Delaware and the southern
portion of the eastern shore of Maryland. Going a bit inland,
however, it may be hard for the cold air at the surface to scour
out, so precip may fall as a period of snow or a wintry mix west of
the Garden State Parkway to the I-95 corridor. Minimal amounts of
QPF expected, and PoPs will be capped at slight chance to maybe low
chance. Not expecting accumulating snow, so no products will be
issued.

&&

.LONG TERM /FRIDAY THROUGH WEDNESDAY/...
Summary...The air mass moderates some Friday ahead of a cold front,
then colder again Saturday into Sunday. Milder air should overtake
our area early next week, however strengthening onshore flow may
temper or delay the warming at least some.

Synoptic Overview...A closed low slides across eastern Canada and
the Northeast Friday into Saturday, while a southern stream closed
low reaches the Southeast coast Saturday morning. The latter shifts
eastward during Saturday and Sunday taking surface low pressure with
it. A strong surface high moving across New England should wedge
southwestward into the Mid-Atlantic slowing the initial forward
motion of the ocean storm. The storm tracks northeastward through
early next week and makes its way well off the Mid-Atlantic coast.
Lots of energy dropping into the Plains and Gulf coast regions
should carve out a large trough during early next week. Strong short
wave energy into the base of this trough may develop another ocean
storm off the Carolina coast near Tuesday before it also takes a
similar track to the northeast. The surface high may be more removed
for this second storm, therefore if the overall trough amplifies
fast enough the surface low could be pulled closer to the coast.
This becomes less certain especially the details this far out,
however some model guidance is showing a potentially strong surface
low off our coasts in the later Tuesday through Wednesday time
frame.

For Friday...A potent closed low dropping southeastward from Hudson
Bay Canada Friday will carve out a trough into the Northeast. This
will drive a mainly dry cold front across our area late Friday,
however some warm air advection ahead of it will help boost
afternoon temperatures to around 50 for many. Meanwhile, energy
diving across the southern states closes off as is nears the
Southeast coast. This will induce surface low pressure development
along a lingering baroclinic zone just off the Southeast coast. As
this occurs, strong high pressure is forecast to build eastward from
near the Great Lakes region and should help to keep a developing
area of rain well to our south. In addition, the low-level flow
turns north to northeast Friday night and increases some and given
the aforementioned surface high much drier air should be advecting
southward into our area.

For Saturday and Sunday...The model guidance remains in good overall
agreement with the large scale features. Southern stream energy
results in an ocean storm off the Southeast coast, which then tracks
northeastward through Sunday night. While the bulk of this system
should remain far enough offshore to keep much of the precipitation
out of our area, some mainly light rain cannot be ruled out
especially later Sunday closer to the coast. Given strong surface
high pressure slowly shifting away from New England, it may provide
enough subsidence to keep the associated ocean storm rain shield
just south and east of our area. However, the presence of the
surface high and the offshore surface low will result in a tight
pressure gradient, and therefore a gusty northeasterly wind is
expected especially closer to the coast. Following a cold front
Friday night, the surface high initially building by to our north
will result in a north to northeast surface wind and bring in colder
and noticeably drier air. Saturday should feature more sunshine due
to the greater influence from the surface high, then clouds increase
Sunday as the storm tracks east of the Carolinas. The PoPs start to
increase up the coast during Sunday and expand inland some Sunday
night, however this is less certain given the offshore track of the
storm and much drier air still holding on especially inland (PoPs no
higher than low end chance). The low-level dry air will eventually
start to erode some late Sunday especially closer to the coast.

For Monday through Wednesday...The evolution of the upper air
pattern is an amplified one, however the details are less certain.
As one low pressure slides by well offshore to start Monday, the
flow aloft amplifies to our west with a potentially significant
trough shifting eastward through mid week. The timing of the
embedded short waves will be crucial as at least the 00z ECMWF looks
to phase things which results in a stronger trough in the East and
therefore a much stronger surface low off the northern Mid-Atlantic
coast Wednesday. Some other guidance however keeps things separate
and therefore a weaker surface low that tracks farther offshore.
There is some potential given the scope of the incoming trough, and
given the details are less certain this far out in time we therefore
generally blended the 00z WPC guidance in with continuity.

.AVIATION /09Z THURSDAY THROUGH MONDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.

Today...VFR. SCT-BKN cirrus possible throughout the day. SW winds
less than 10 kt. High confidence.

Tonight...Mostly VFR. Winds become LGT/VRB. After 06Z, sub-VFR
conditions possible in rain at KACY, and a rain/snow mix at KMIV.
Moderate confidence.

Outlook...
Friday and Saturday...VFR. Light and variable winds becoming west-
northwest 5-10 knots during Friday then turning north Friday night
10-15 knots before shifting from the northeast with gusts to around
25 knots Saturday (strongest mainly at ACY). Moderate confidence.

Sunday and Monday...VFR ceilings, with MVFR ceilings possible
especially closer to the coast with a chance of some rain. Northeast
winds 10-15 knots with gusts to around 25 knots (strongest mainly at
ACY and MIV). The winds should diminish some Monday. Low
confidence.

&&

.MARINE...
Sub-SCA conditions on tap for today and tonight. SW winds around 10
kt, becoming W late tonight. Seas 2-3 feet.

Outlook...
Friday and Saturday...The conditions are anticipated to be below
Small Craft Advisory criteria during the day Friday, then winds
become northerly Friday night and increase. Gale force gusts are
quite possible later Friday night through Saturday night. Seas will
become rough. A Gale Watch has been issued for all areas except for
Upper Delaware Bay late Friday night through Saturday night.

Sunday and Monday...Periods of northeast gale force wind gusts are
quite possible along with rough seas. The winds however should
diminish some on Monday.
