Synopsis
High pressure over the canadian maritimes will move into the
open atlantic waters today as a cold front moves through the
great lakes region. The front will move through the local area
late tonight and into early Saturday morning and stall to the
south, with canadian high pressure building in this weekend and
into Monday. A warm front will then pass through Monday night
into Tuesday, followed by a cold front on Wednesday, the front
should stall to out south on Wednesday while high pressure
builds to its north.

Near term until 6 pm this evening
Another night of moisture remaining trapped beneath a subsidence
inversion resulting in stratus. Not expecting much in the way of
clearing today, perhaps partly sunny across portions of LI and
se ct this aftn, otherwise mostly cloudy.

The local area will remain warm sectored today as high pressure
near nova scotia shifts into the atlantic and strengthening low
pressure over the western great lakes tracks NE through southern
canada. A tightening pressure gradient will result in increasing
southerly winds with gusts 20 to 25 mph, highest at the coast.

Outside of a few showers across NW areas late, it should be dry
today.

High will be near normal today ranging from the upper 60s into
the lower 70s, mid 70s in the metro area.

There is a moderate risk for the development of rip currents at
the ocean beaches of new york city, nassau and southwestern
suffolk counties, and a high risk at the southeastern suffolk
atlantic beaches today.

Short term 6 pm this evening through 6 pm Saturday
As the cold front approaches this evening, the chances for
showers and possibly some tstms will increase. For the past 3
nights model guidance has been consistently indicating that the
severe threat would remain N and W of the local forecast area
due to the lack of instability from limited height falls aloft.

Additionally, with the low passing so far to the north, the
majority of the shortwave energy also remains to the north.

There is some elevated instability present with showalters
between 0 and -1 c so have maintained the schc tstms, but severe
weather is not expected. The line of showers and tstms is
expected to weaken as it approaches and moves through as it
enters a more stable environment. Any lingering pcpn should be
south of long island by Sat morning.

Canadian high pressure builds to the N behind the front
providing a dry and seasonable day on sat.

There is a moderate risk for the development of rip currents at
the ocean beaches on sat.

Long term Saturday night through Thursday
Wx should remain dry Sat night through Mon with weak high pressure
over the area, though we should see some clouds from the stalled
cold front to the south, especially across nyc metro and long
island. As mid level confluence in the wake of a departing nrn
stream trough passes across the canadian maritimes early next week,
associated strong sfc high pressure will move across new england,
with a back door cold front dropping into the area from the north on
mon and dissipating. An upper level ridge axis should slide quickly
across Mon int Mon evening, then return flow on the back side of the
sfc high and an approaching warm front should bring increasing
chances for precip beginning late Mon night and going into the mid
week period. Could see a few heavier showers with the warm front on
tue as it lifts through, then showers tstms with a cold front moving
through. If latest ECMWF is right Thu could be dry, but with the
front aligning with the flow aloft and models often too
progressive at longer time ranges, still could see at least
slight chance pop for post-frontal showers, especially nyc
metro and long island.

Temps Sat night into Mon should range slightly below avg, with highs
in the upper 60s and lower 70s. Temps should them warm to above avg,
by wed, with highs 75-80, and a return of 70+ dewpoints as well.

Temps on Thu after cold FROPA should then trend back closer to avg.

Aviation 12z Friday through Tuesday
High pressure shifts offshore on Friday as a cold front
approaches late Friday night.

PredominantlyVFR today, however a period of MVFR may linger
for the next few hours. Southeast winds becoming
south southwesterly this morning. Gusts 20-25kt, with the higher
gusts along the coast.

Showers will approach the region overnight into Saturday
morning but are forecast to weaken and dissipate as they
approach. Have kept a prob30 for chance showers. CIGS should
remainVFR but could briefly drop to MVFR in any heavier shower.

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.
