Area Forecast Discussion
National Weather Service Mount Holly NJ
1239 PM EST Sun Jan 7 2018

.SYNOPSIS...
Arctic high pressure centered over the Mid-Atlantic region today
will move offshore tonight. Low pressure will track eastward across
eastern Canada early in the week. A cold front accompanying this
system will move through the region Monday night into Tuesday
morning. Another area of high pressure will build in from the west
Tuesday afternoon and night before progressing off the eastern
seaboard on Wednesday. A cold front will slowly approach from the
west late in the week into early next weekend. Meanwhile, an area of
low pressure may develop along this front and track near or just
west of the region either Friday or Saturday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

The surface high will move across the Mid-Atlantic today and then
slide to our south through this evening. The strong upper trough
will finally exit the region and take the bulk of the arctic air
with it.

Behind this trough, we should see some moderating of the temperatures
across the region as the flow turns more to the west and southwest
through the day. Sunshine will start to fade late as high clouds
filter into the region. While temperatures will still be cold
(on avg 10-20 degrees below normal), it should feel a bit warmer
outside.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM MONDAY/...
Increasing cloud cover across the region as the next system
approaches the area. Conditions are expected to remain dry through
tonight.

Winds will go light overnight and usually we would expect
temperatures to tank rapidly, especially in areas with substantial
snow on the ground. However, the increased cloud cover will limit
efficient radiational cooling and we will end up being more moderate
(compared to recent nights) in temperatures overnight. With little
wind, the wind chills will not be nearly as brutal as they have been
but it will still feel pretty cold outside.

&&

.LONG TERM /MONDAY THROUGH SATURDAY/...
Monday and Monday night...Low pressure will pass well north of our
region across central portions of Ontario-Quebec provinces. The cold
front accompanying this system will progress eastward across the
Great Lakes region on Monday and eventually through the Mid Atlantic
late Monday night. Southwesterly flow ahead of the front and on the
backside of the offshore high will advect warmer air into the region
on Monday. Despite the warming trend, temperatures may not rise
above freezing on Monday, especially for inland areas (N/W of I-95).

Models generally show a band of precip moving from W-NW to E-SE
across the region Monday afternoon and evening when isentropic lift
is maximized with the arrival of a SWly low-level jet prior to the
arrival of the cold front. Analysis of thermal profiles show models
are in decent agreement regarding precipitation type and have been
fairly consistent run to run despite a rather complex setup with
multiple ptypes expected with this event. Mainly snow is expected
north of I-80 and west of I-287. Farther south across E PA and C/S
NJ (roughly along and south of I-78 corridor)as well as northern
Delmarva, thermal profiles indicate enough warming aloft for a
wintry mix (snow, sleet, freezing rain). The biggest concern with
this event will be freezing rain as snow/sleet accumulations will be
light (an inch or less). Ice amounts are currently projected to
be under one-tenth inch. Despite the light icing, factors that
could potentially heighten travel impacts is the timing of the
freezing rain coinciding with the late afternoon-evening commute
and the antecedent cold ground. Regarding the latter factor:
Even if temperatures briefly rise above freezing prior to the
arrival of the precip, skin temperatures will be much slower to
respond and likely remain sub freezing. This will allow for ice
to accrete on untreated roads. The area at greatest risk for
icing impacts still appears to be in SE PA, C and S NJ, NE MD
and N DE. Barring a significant shift in the forecast, a Winter
Weather Advisory may be needed for the aforementioned areas.

Tuesday and Wednesday...The cold front will move offshore during the
morning. High pressure builds overhead Tuesday night before moving
offshore on Wednesday. With the post-frontal CAA pattern short-lived
Tuesday morning, a drastic cool down is not expected. Relative to
how cold it's been lately, Tuesday and Wednesday will feel rather
mild with highs ranging from the mid 30s in NE PA and NW NJ to the
mid 40s toward the mid Delmarva.

Wednesday night...Cannot rule out an area of light precip
overspreading our far northwestern zones (mainly along and north of
I-80) owing to stronger isentropic lift along a northward moving
warm front. However, with the deeper forcing for ascent ahead of a
mid-level shortwave trough expected to pass to our north, the
likelihood of organized precip this far south is low. PoPs were
capped at 20 percent. If precip does materialize, a shallow layer of
colder air trapped at the surface could result in freezing rain.
Therefore, we will continue to monitor this closely.

Thursday through Saturday...The latter portion of the long-term
period looks to be wet and mild. The region will be situated in
broad S-SW return flow around the offshore high and ahead of a
slow-moving cold front to our west. Temperatures both Thursday
and Friday will likely climb into the 50s for most of the
forecast area except maybe the higher terrain north of I-78.
Temperatures on Saturday are much more uncertain and will depend
on the timing/location of the cold front relative to our CWA. A
large spread in QPF amounts for this three-day period exist
among the operational models and their ensembles but there is
increasing support for 1-2 inches of rainfall. Given the
majority of the existing snow pack will melt prior to the
arrival of the potentially heavier rains and since the present
snow pack is located in the coastal plain (downstream of the
larger river basins), do not anticipate significant hydro
problems unless the forecast trends wetter.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

Today...VFR conditions expected. West to northwest winds becoming
more southwest through the day. Wind speeds around 5 to 10 knots.
Increasing mid/high level clouds this afternoon. Confidence: High

Tonight...VFR conditions expected. Southwest winds will become light
overnight. Broken to overcast skies with bases above 5000 feet.
Confidence: High

Outlook...

Monday and Monday night...Sub-VFR possible for a 3-6 hour period
between 18-00Z for RDG/ABE and 21-03Z for I-95 and coastal
terminals. During this time, a light wintry mix is likely.
Predominant ptype looks to be SN/IP at RDG/ABE and IP/ZR for
I-95 the other TAF sites including PHL. S-SW winds 10 kt or
less, becoming W-NW late Monday night behind a cold front.
Moderate to high confidence.

Tuesday through Wednesday night...VFR. Winds 10 kt or less.
High confidence.

Thursday...Sub-VFR conditions possible with increasing chances
for rain. Low confidence.

&&

.MARINE...
Low water advisory dropped for northern Delaware Bay.

West to northwest winds will become Southwest late. Winds speeds
mostly under 10 knots. Fair weather today.

Ice continues to develop in the Delaware Bay. With temperatures
remaining below freezing, additional ice is likely to form. Wave
forecast on the Delaware Bay is for ice free waters.

OUTLOOK...

Monday and Monday night...A SCA will likely be issued for the
coastal marine zones. W-SW winds increase ahead of a cold front
with the setup for 25+ kt speeds more favorable as you travel
southward along the coastline and away from the nearshore
waters. Seas are forecast to peak to near 5 ft in the outer part
of the coastal water zones.

Tuesday...Winds veer out of the W-NW behind a cold fropa early. A
brief surge behind the cold front could extend SCA-level gusts into
at least the morning.

Tuesday night through Thursday...Winds and seas below SCA
criteria.

&&

.TIDES/COASTAL FLOODING...
Low water SPS continues for the tidal Delaware River through the
early afternoon. Tidal departures are improving (getting closer
to -1.5 instead of -2.0 as earlier).

There is an low possibility that low water conditions may occur
again tonight in the tidal Delaware River. Current total water
level forecasts keep levels just shy of the 2 ft below MLLW
criteria. We take a look later this afternoon.

&&

.CLIMATE...
Today marks the last day of this bitter cold that has affect
the area for much of the past two weeks with a gradual warm up
on Monday.

One daily minimum temperature record was tied yesterday
(January 6th)...7 degrees at Wilmington, DE (ILG) tied the
previous record set in 1924 and 1942. Daily record low maximum
temperature records were also set yesterday at Wilmington,
Philadelphia, Reading and Atlantic City.
