Synopsis for the coastal waters from sandy hook nj to fenwick island de and for delaware bay.. Low pressure developing off the carolina coast will move northward tonight before shifting northeastward near or off the new england coast Wednesday. A broad area of high pressure will build into the eastern u.s. Late this week through the weekend. A strong surface low will develop in the central plains late this weekend, moving rapidly northeastward through the great lakes and southeast canada early next week, which will allow a strong cold front to swing through the mid-atlantic by next Tuesday.

area forecast discussion

1244 am est Wed jan 17 2018

Synopsis
A low pressure system and front will approach from the great
lakes region overnight. Another low will develop off the coast
and affect the weather overnight and early Wednesday. More high
pressure will build towards the area late this week and remain
for the weekend. Low pressure and a cold front will move toward
the middle atlantic region for the start of next week.

Near term until 6 am this morning
Snow was falling across most of eastern pennsylvania and
northwestern new jersey around midnight. The leading edge of the
precipitation along and approaching the interstate 95 corridor
was falling as rain.

A cold front approaching from the west will move across our
region during the balance of the night. Meanwhile low pressure
will continue to take shape off the middle atlantic coast.

The precipitation will work its way eastward. The boundary
layer is expected to begin cooling and the snow rain line will
progress eastward reaching the coast before daybreak.

It continues to appear as though the more substantial snow will
become focused in northern and central new jersey toward
daybreak. We will keep the snow total forecast going but it may
be a bit high in spots, especially in parts of southeastern
pennsylvania. We will keep an eye on trends and we may make some
minor adjustments in our next update.

Temperatures are forecast to fall about 5 degrees by daybreak.

A northwest wind around 10 mph is expected to develop in our
region.

Short term 6 am this morning through 6 am Thursday
The accumulating snow should be over by midday for just about
the entire area. However, very light snow or flurries could
linger or redevelop during the afternoon near the coast as the
upper low and associated upper-level jet streak approaches from
the southwest.

High temperatures range from the mid 20s in northeastern pa to
mid 30s in central southern nj, philadelphia, and delmarva.

Long term Thursday through Wednesday
Main focus of the long term is the warmup late this week
through this weekend and a storm system moving through the
region early next week. Most of the focus today was on the first
36 hours of the forecast, so overall made few changes from the
previous shift.

Trough axis swings through the eastern seaboard Wednesday
night, with a broad surface high building into the mid-atlantic
and southeast for the rest of the week into the weekend. After a
small- scale perturbation moves through the northeast Thursday
night (which should be dry), midlevel zonal flow will be present
Friday through the weekend, allowing the surface high to slide
eastward and promoting southwesterly surface flow to develop
east of the appalachians this weekend.

This pattern will result in a lengthy dry period and a distinct
warming trend after a chilly Thursday (when heights thicknesses
will be lowest, owing to the proximity of the trough). Forecast
highs are in the 50s for philly this weekend, based on a
consensus blend of statistical guidance... Though I leaned a
little on the higher side of consensus given the tendency for
mos to be on the low side in warming patterns.

Operational models develop a strong surface cyclone in the
central plains this weekend (with downstream ridging further
contributing to warmth Sunday and Monday in our area) before
lifting it rapidly northeastward into the great lakes and
adjacent southeast canada early next week. A strong cold front
will progress through the east Monday and Tuesday, with showery
precipitation developing near the front. Temperatures will
likely be warm enough for liquid in most locations for the
event, with the exception being the far northwest CWA during the
precip's waning stages.

Regarding timing, models generally agree on Monday afternoon
through Monday night. Given such good agreement this far out,
boosted pops to high chance or likely during this time frame.

The greater uncertainty lies with the intensity of the
precipitation (given the southern origins of the system and the
warmth it advects downstream, there is some potential for decent
precipitation totals, especially if embedded convection can
develop), extent of cold air on the upstream side of the system
(i.E., precipitation type issues as the system departs), and the
speed with which the precipitation moves out before the colder
air moves in.

As previously mentioned, did not change the details during this
time frame too much, but my initial thoughts were to go on the
warm side and on the quick side given typical model biases with
northeast- progressing inland surface lows originating from the
southern southwestern u.S.

By midweek, temperatures will be slightly cooler, and
conditions should dry out.

Aviation 06z Wednesday through Sunday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Overnight... Conditions lowering to ifr in snow. A generally
light accumulation at krdg, kabe and kttn. Little or no
accumulation at kpne, kphl, kilg, kmiv and kacy. A light and
variable wind becoming northwest around 8 to 10 knots.

Wednesday... Ifr in the morning improving toVFR for the
afternoon. The snow is forecast to end between about 1200z and
1400z at most locations. A northwest wind around 10 to 12 knots
gusting near 20 knots.

Outlook...

Wednesday night...VFR with northwest winds 5 to 15 kts. High
confidence.

Thursday through Sunday...VFR with light west or southwest
winds. High confidence.

Marine
Overnight... Seas at our nearby offshore buoys continue to
remain elevated between 4-6 ft this afternoon despite a light
onshore wind. We extended the SCA into tonight with the latest
guidance keeping seas around 5 ft through tonight.

Wednesday... Nw winds will strengthen in response to a deepening
coastal low that tracks just to the east of our waters. Expect
wind gusts to increase from S to N across the region during the
day with gusts around 25 kt. Seas will be steady state between 4
and 6 ft. The SCA continues for the coastal waters. Additional
sca was issued for the lower de bay for winds.

Outlook...

Wednesday night and Thursday: freezing spray possible near the
coast and in delaware bay. Small craft advisory conditions for
lower delaware bay and the atlantic waters, with gusty northwest
winds and seas near 5 feet slowly diminishing by Thursday
afternoon.

Thursday night through Sunday: sub-advisory conditions and fair
weather expected.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
