Special Weather Statement, NWS Philadelphia/Mount Holly

Area Forecast Discussion
National Weather Service Mount Holly NJ
725 PM EST Mon Jan 30 2017

.SYNOPSIS...
Low pressure will move farther out to sea tonight while high
pressure builds along the Eastern Seaboard. The next clipper
low over the Great Lakes Tuesday will track eastward through the
Northeast and into the Gulf of Maine Tuesday night and
Wednesday. A cold front is expected to arrive Wednesday night,
then high pressure builds in late this weekend into Saturday. A
storm system approaching from the southwest late in the weekend
may redevelop off the Mid-Atlantic coast Sunday night and
Monday.

&&

.NEAR TERM /UNTIL 6 AM TUESDAY MORNING/...
700 pm update: Snow squalls that passed through much of the area
earlier are weakening as expected early this evening. Several
reports of a few tenths to even an inch of snow in many spots
generally a county or so north and south of the Mason-Dixon Line
this afternoon. Current grids have the downward trend in
precipitation well-handled and did not change this evening.
However, given the quick burst of snow in several spots and
subfreezing surface temperatures, icy patches may be encountered
on area roads through this evening.

Main changes to the grids were to tweak temps/dews/sky cover to
match current trends. Expect a brief period of decreasing clouds
this evening before increasing cloudiness later tonight as the
next system approaches. Rest of forecast unchanged, with
previous discussion below...

A potent upper-level trough, evident on water vapor imagery,
continues to pivot across and east of our area this afternoon.
Strong short wave energy within this trough along with steepening
low to mid level lapses rates is helping to drive some snow
showers. The forecast soundings indicate some instability,
which enhancing the snow shower development. Radar imagery shows
what appears to be a meso-low type feature moving through
portions of central Pennsylvania this afternoon. This will
continue to move east- southeastward and potentially enhance the
snow showers in its vicinity. There are some embedded squalls
as well, which will be accompanied by a rapid reduction in the
local visibility for a brief time. Some of the heavier snow
showers/squalls will produce a quick coating into early this
evening. The main targeted area is mostly from about the
southern Lehigh Valley area to Ocean County on southward.

The snow showers and squalls are expected to end early this
evening from west to east as the forcing shifts offshore and
the instability wanes. We are then between systems briefly with
some possible thinning of the clouds, then low-level warm air
advection starts to develop overnight from southwest to
northeast ahead of a vigorous clipper system. This will allow
the clouds to thicken up late especially the northern half of
the area. It appears that any overrunning snow does not arrive
until Tuesday, therefore after the snow showers end early this
evening a dry forecast is carried. Low temperatures were mostly
a MOS blend.

&&

.SHORT TERM /6 AM TUESDAY MORNING THROUGH 6 PM TUESDAY/...
A vigorous short wave exiting out of the Midwest this afternoon
will track eastward during Tuesday. This will drive a surface
low, clipper system, eastward from the Great Lakes region. This
feature may weaken some by later in the day as the short wave
shears eastward some. There will be increasing low-level warm
air advection occurring which will enhance a ribbon of lift
during the day, especially through about mid afternoon. This is
centered mostly across our northern zones where even a period of
decent lift is within the dendritic snow growth zone. As a
result, there should be a period of decent snow across the
Poconos to northern New Jersey where the air is the coldest
(higher snow ratios). While this should produce a swath of 1-3
inches of snow with the higher amounts in the Poconos, the area
of strong lift and potential for a band of heavier snow could
set up just to our north. There is enough model consensus to
keep snow amounts fairly close to continuity.

We did increase the PoPs into the categorical range for awhile
however. Farther to the south, some light snow may occur down to
about Philadelphia however we lowered the PoPs southward given
much of the lift looks to be farther to the north. Therefore the
PoP gradient from south to north was tightened up, with the
southern areas potentially seeing little to no precipitation
from this. Given the timing during the day and forecast snow
amounts, we opted to hold off on a winter weather advisory.

As the system starts to track over or just to our north during
the afternoon, the best forcing should start to exit our
northern zones. As a result, it may turn more showery with even
some showers possible farther to the south. The thermal profiles
should remain plenty cold for all snow mostly north of I-78
with some rain/snow farther south or a change to rain showers. A
low-level jet arriving across the southern areas should drive
more warming down there.

High temperatures were mostly a continuity/MOS blend. This
results in much milder air across the far southern areas, with
colder air hanging on across the northern areas.

&&

.LONG TERM /TUESDAY NIGHT THROUGH MONDAY/...
An active northern jet stream will be present through the long-term
period with a seemingly endless train of clipper systems progressing
eastward along the northern U.S and southern Canada. A stronger
storm system could impact the region late this weekend. Slightly
above normal temperatures at the start of the period (through
Wednesday) but trend colder with below normal temperatures likely
Thursday through Monday.

The clipper low will eventually pull away from the Gulf of Maine
Tuesday night and out to sea Wednesday into Thursday. This will
allow a cold front to move through the region late Wednesday. We
will continue to indicate a dry fropa based on overwhelming model
support. However, there are a few GEFS members and GGEM that shows
lee cyclogenesis to the east of the southern Appalachians. This weak
surface low would then track northeastward along the front and off
the southern Mid-Atlantic coast, but potentially close enough to
provide a quick shot of light snow to Delmarva/S NJ sometime
Wednesday late afternoon or night.

Yet another clipper low will be quick on its heel, tracking eastward
across southeastern Canada into northern New England. It will bring
another cold front through the region Thursday that provides a
reinforcing shot of cold air. We do not anticipate much impact on
our sensible weather with the forcing for ascent and precipitation
remaining well to our north. However, forecast soundings show steep
lapse rates in the boundary layer, which could support lake-effect
snow streamers at least as far downstream as the southern Poconos.

High pressure builds in behind the front Thursday night and Friday.
Similar to the scenario for late Wednesday, models develop a
secondary wave along the cold front to the lee of the southern
Appalachians on Friday. Currently, the track of the low looks to be
suppressed far enough south to spare our area from snow. This will
have to be watched though for northward trends that would increase
chances for light snow across our far southern forecast zones late
Friday.

The center of the high will progress eastward from the Midwest to
the Mid Atlantic on Saturday-Saturday night. Seasonably cold and dry
conditions can be expected for the first half of the weekend. The
high will then retreat offshore on Sunday as a storm system
approaches from the southwest. As noted over the past few days,
there is a potential for this system to phase with some northern
stream energy as it heads toward the east coast. There is increasing
support for secondary cyclogenesis somewhere near the Mid-Atlantic
coast, but the strength and track of the coastal low will be
dependent on how much and when the phasing of both streams occurs.
Still too early to discuss specific impacts from this storm with
such a wide range of plausible scenarios on the table. Nonetheless,
there should be enough cold air for snow at least at the onset. PoPs
were raised for Sunday afternoon-night.

&&

.AVIATION /00Z TUESDAY THROUGH SATURDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY and surrounding areas.

00Z TAF update: Not much change to the TAFs this evening. Although
an isolated snow shower cannot be ruled out early this evening,
think these are done at the TAF sites. Expecting VFR conditions
through 09Z with conditions deteriorating to MVFR from west to
east across the area 09Z-13Z. Light snow is likely at KABE,
KRDG, and KTTN for a few hours during the morning and at least
possible at KPNE, KPHL, and KILG, though confidence remains too
low for inclusion at this time. Ceilings/visibilities will
likely lower to IFR for a time during the snow. Expect
transition of any snow to rain or rain showers south of KRDG and
KTTN by late morning. Winds will transition to south or
southeast by morning, then veer to southwest by afternoon with
improving ceilings/visibilities, especially late in the day.

OUTLOOK...

Tuesday night through Saturday...Predominately VFR. W-NW winds will
become breezy each day with gusts 20-25 kt generally expected during
the daytime hours.

&&

.MARINE...
As an upper-level features moves through this afternoon and early
this evening, northwesterly winds may increase for a time. There
then should be a lull into Tuesday before a low-level jet arrives
especially across our southern waters. This is within a warm air
advection regime therefore mixing should become less efficient with
time. Still appears to be a period of gusts up to 30 knots during
Tuesday especially on the Atlantic coastal waters, therefore
extended the Small Craft Advisory through the day Tuesday. If some
gale force gusts occur mainly across the southern Atlantic waters
Tuesday, they should be short in duration and therefore the Gale
Watch has been dropped.

OUTLOOK...

Tuesday night and Wednesday...Winds veer from the west but weaken
briefly during the evening.
Winds then increase with SCA likely in the Atlantic coastal waters
late Tuesday night and Wednesday. A pressure surge behind a cold
front could produce gusts to near gale force early Wednesday morning
but confidence too low to issue a headline at this point.

Wednesday night through Saturday...An extended period of SCA
continue through the end of the week with W-NW winds gusting to
around 25 kt.

&&

.CLIMATE...
432 PM CLI preliminary snow amounts basically are unknown today
due to ongoing snow. Our midnight climate issued around 135 AM
Tuesday January 31 will have the final amounts for Philadelphia,
Atlantic City, Wilmington and Allentown.

We'll try to have some preliminary values in an evening PNS issued
around 730 PM.

Also...later tonight we'll have an update on the monthly average
temperatures and ranking for PHL ABE and ACY.
