Synopsis for the long island waters and new york harbor.. High pressure builds in from the north today, however a weak low pressure trough will be passing to the south at the same time. High pressure then weakens on Friday as it moves offshore and another weak area of low pressure shifts through near us. A cold front moves through Friday night as high pressure builds to the north. A warm front approaches Sunday, and a cold front passes late Sunday. High pressure builds early next week.

523 am est Thu feb 22 2018

Synopsis
High pressure builds to our north today into tonight as a
frontal boundary becomes stationary to our south. The high will
build offshore of new england Friday as an area of low pressure
moves out of the great lakes region Friday, and across southeast
canada Friday night. This will pull a cold front across the
area, which may get hung up across our southern areas Saturday.

This front may begin lifting back northward slightly Saturday
night into Sunday as an area of low pressure lifts through the
great lakes region Sunday. This will pull a cold front across
the area by late Sunday into Sunday night. High pressure begins
to build into the region Monday and Tuesday.

Near term until 6 pm this evening
Cold front has pushed south of our forecast area as evidenced
by winds shifting to the north through de. Temps have fallen
into the 40s north but still 60s south. Skies are cloudy
everywhere but for the moment only light spotty showers are
moving across northern nj with no precip elsewhere.

For today... With cloudy skies and continued low-level cold
advection behind the front, temperatures will just hold steady
or perhaps fall a few degrees during the day. Afternoon temps
will range in the 30s and 40s over nj and east pa, and in the
50s over northern delmarva.

The regional radar loop shows an area of rain from west pa
southwest through the oh valley, which is forecast to overspread
the region today. By late afternoon, temps may fall to around
freezing in the poconos and far northwest nj, so there is the
threat for some freezing rain. Hence a winter weather advisory
has been issued for carbon and monroe cos in pa and sussex co in
nj.

This is a rather low-confidence advisory as there are mixed
signals from the model guidance as to precip type (rain,
freezing rain or sleet) and whether precip will end before temps
fall below freezing late this afternoon or evening. The advisory
might need to be extended or re-issued for late tonight or early
Friday morning, as another batch of precip is forecast to move
in around that time.

Short term 6 pm this evening through 6 am Friday
Rain is forecast to taper off this evening but we are maintain
chance pops through the night. Temps will continue to fall into
the evening and sub-freezing temps will be more widespread over
nw nj and adjacent pa. There may be some lingering freezing rain
over these areas so the winter weather advisory extends through
the evening hours.

Long term Friday through Wednesday
The first half of the long term period is forecast to be a bit
unsettled with several rounds of precipitations late this week
into this weekend. Then dry weather returns again for the early
to middle of next week.

On Friday, high pressure will build offshore of new england,
while the frontal boundary to our south may begin to lift
slightly northward. Meanwhile, a cold front will be moving
toward the area from the west as an area of low pressure lifts
out of the great lakes region and across southeast canada
through Friday night. North of this warm front, and in advance
of the approaching cold front, there will be several short
wave vorticity impulses move across the area. This will lead to
enhanced lift across the area, which will combine with enhanced
moisture aloft to create a period of precipitation from Friday
morning through Friday evening. The rainfall will likely begin
to taper off Friday evening, although some patchy drizzle may
linger into the overnight hours. Temperatures will likely be
below freezing for portions of northeastern pennsylvania and
northwestern new jersey Friday morning into early afternoon
Friday. This will likely lead to a period of freezing rain.

Since there will be likely be a break in freezing precipitation
this evening and overnight, we will not extend the advisory
through Friday morning at this time.

The frontal boundary is then expected to become nearly
stationary across our southern areas, or just to our south for
Saturday into Saturday night. A couple of short wave vorticity
impulses are forecast to move across the area Saturday into
Saturday night, which will lead to enhanced lift across the area
and a couple of rounds of precipitation. Then on Sunday, a cold
front is forecast to move across the area, which will bring
another period of rainfall to the area.

We expect three separate periods of enhanced rainfall from
Friday through Sunday, with a chance of light rain or drizzle
possible in between each. Each period of rainfall could bring up
to a half inch to three quarters of an inch at a time,
especially Sunday. Right now it looks like much of northeast
pennsylvania and northern new jersey could see the bulk of the
rainfall Friday through Saturday night, with everyone seeing
enhance rainfall Sunday. Even with a break between each period
of rainfall, some rivers and creek could see some rises through
the weekend.

After this extended period of rainfall, dry weather is forecast
to return to the area for the early to middle of next week.

High pressure is forecast to begin approaching the area from the
west on Monday, then fully build across the east coast Tuesday,
before moving offshore Wednesday.

Aviation 10z Thursday through Monday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Today... Current conditions areVFR except at acy and miv with
cigs around ovc025. Rain will be moving into the area from west
to east later the morning and conditions will deteriorate to
MVFR and eventually ifr this afternoon. Winds should be fairly
steady from the northeast at around 10 kt.

Tonight... Rain should taper off during the evening and
visibility should improve. However CIGS are forecast to remain
in the ifr range. This is due in part to continued low-level
flow off the ocean, with surface winds continuing from the NE at
5 to 10 kt.

Outlook...

Friday-Friday night... Ifr conditions expected with period of
rain during the day. Patchy drizzle may develop later in the day
into the evening. East to southeast wind during the day, become
southwest then west during the evening and overnight. Moderate
confidence.

Saturday-Saturday night... Conditions may improve toVFR briefly
by midday, before diminishing again to ifr by the afternoon and
evening as rainfall moves back into the area. Winds shift back
to the northeast then east during the day and continue into the
night. Moderate confidence.

Sunday... Ifr conditions for the first half of the day as a cold
front moves across the area with a period of rainfall. East to
southeast winds become southwest and west behind the front.

Moderate confidence.

Sunday night...VFR conditions return. High confidence.

Monday...VFR. Gusty west to northwest winds 15-20 knots. High
confidence.

Marine
The cold front has passed north to south across the forecast
waters and winds have shifted to the north behind the front.

Winds should veer some to the NE today and increase to around 20
kt, with gusts 25 to 30 kt. Seas will also build in response to
the increasing NE winds. A small craft advisory is in effect
starting midday. Wind should begin to diminish tonight but seas
will remain elevated.

Outlook...

Friday... Small craft advisory extended into Friday as seas
likely to remain elevated, although winds drop off below
advisory levels.

Friday night-Saturday night... Conditions expected to remain
below advisory levels.

Sunday-Sunday night... Small craft advisory level seas may
return to the waters Sunday, before lowering overnight Sunday
night.

Monday... Conditions expected to remain below advisory levels.

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.
