Area Forecast Discussion
National Weather Service Mount Holly NJ
1020 AM EDT Mon Mar 20 2017

.SYNOPSIS...
High pressure located along the Appalachians early this morning
will sink to the south and it should begin to lose its
influence over our weather today. Weak low pressure approaching
from the west is forecast to pass off the Middle Atlantic Coast
on Tuesday. A cold front from the north is expected to arrive
late on Tuesday night followed by strong high pressure. The
center of the high is anticipated to pass nearby on Thursday
before moving slowly out to sea. A warm front is forecast to
lift through our region on Friday. Low pressure is expected to
approach from the west over the weekend.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
A nice day for the first day of Astronomical Spring, although
there remains some snow on the ground for many areas and
temperatures are expected to be a few degrees below normal. The
recent visible satellite pictures clearly show the snow on the
ground N/W of the fall line (roughly KBLM-KTTN-KPHL).

Sunny skies will prevail into the early afternoon before high
and mid level clouds arrive from the N/W. High pressure builds
to our south through the day and weakens its grip on our area.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 AM TUESDAY/...
Tonight, a weak surface trough will approach the area
overnight, while a weak low pressure approaches our southern
areas as well. The low will stay south of the area, though the
trough may make its way into the area. At the same time, a mid-
level vorticity impulse will be sliding across the area as well.
There is not a much deep moisture associated with these
features, but there could be enough lift with the disturbance
aloft to interact with the moisture across the area to create
some light precipitation overnight. The most likely areas are
across southeastern Pennsylvania, the Delmarva, and southern New
Jersey. Temperatures across these areas where the precipitation
is most likely are expected to be above freezing and be a cold
rain. Areas across the Poconos and northwestern New Jersey may
drop below freezing for a period overnight, but they are less
likely to see any precipitation. We will still keep a chance of
a wintry mix of rain, sleet, or snow. Thermal profiles don't
show a significant melting potential, so anything snow that
melts may only partially melt and fall as snow or ice pellets
where temperatures are cold enough. If rain does occur and
temperatures are below freezing, a brief period of freezing rain
may occur; but since the potential is small and confidence is
low, so we've kept it out of the forecast for now.

&&

.LONG TERM /TUESDAY THROUGH SUNDAY/...
The mid level pattern is forecast to remain rather progressive
during the period from Tuesday through Sunday, keeping the
weather systems moving along in the flow.

Weak low pressure is expected to be located over Virginia on
Tuesday morning. The feature should pass off the coast on
Tuesday. We are anticipating a fair amount of cloud cover in the
morning, with a decrease in clouds as the day progresses,
especially over eastern Pennsylvania and northern and central
New Jersey. There is a slight chance of morning rain showers in
parts of eastern Maryland and central and southern Delaware.

A cold front is forecast to drop through our region late on
Tuesday night with a robust shot of cold advection in its wake
from late Tuesday night into Wednesday morning. No precipitation
is expected with the front in eastern Pennsylvania and northern
and central New Jersey. However, we will maintain the mention
of a slight or low chance of rain showers in northeastern
Maryland, Delaware and southern New Jersey at that time.

A 1040 HPa high is anticipated to build down from the northwest
on Wednesday with its center passing over or near our region on
Thursday. We are forecasting chilly dry weather for both days.
Wednesday should have a brisk northwest wind with a relatively
light wind expected for Thursday.

The center of the high is forecast to move out to sea on Friday
allowing a warm front to lift through our region in the return
flow. Some spotty rain is possible. Also, there could be some
localized freezing rain in our northern counties on Friday
morning if the precipitation arrives before the temperatures
have time to recover from their morning lows.

A very mild southwesterly flow is forecast to develop for
Saturday as a cold front drops toward our region from the north
and as low pressure approaches from the west.

We will mention a chance of rain for Saturday night and Sunday.
The forecast looks to get complicated for late Sunday into the
early part of the new week. The center of another 1040 HPa high
is expected to build into Quebec with cold air pushing southward
into the northeastern state. We could see some wintry
precipitation at that time in parts of our region.

As is often the case during this time of the year, temperatures
will be all over the place. Daytime highs should be about 10 to
15 degrees below normal on Wednesday and about 10 to 15 degrees
above normal on Saturday with the other days falling somewhere
between the two.

&&

.AVIATION /14Z MONDAY THROUGH FRIDAY/...
The following discussion is for KPHL, KPNE, KTTN, KABE, KRDG,
KILG, KMIV, KACY and surrounding areas.

VFR conditions prevail across the TAF sites and will remain VFR
through the day. Clouds will increase and thicken through the
day, and especially tonight. An area of light rain may affect
the TAF sites overnight, which could temporarily lower
conditions.

Northwest winds 5-10 knots through most of the day will become
more westerly later this evening. Many locations may become
light and variable at times overnight.

OUTLOOK...

Tuesday through Thursday night...Mainly VFR.

Friday...Mainly VFR. A a chance of light rain and localized
MVFR conditions mainly from KRDG, KABE and KTTN northward.

&&

.MARINE...
Winds remain below 25 knots, but seas on the Atlantic Ocean
remain elevated this morning. Seas are expected to subside below
5 feet later in the day, so we've extended the Small Craft
Advisory through the afternoon. Conditions are then expected to
remain below advisory levels through tonight.

OUTLOOK...

Tuesday and Tuesday night...No marine headlines are
anticipated.

Wednesday and Wednesday night...Northwest to north winds may
gust to 25 or 30 knots. Localized gale force gusts are possible.

Thursday through Friday...No marine headlines are anticipated.
