Synopsis
A low pressure and a trailing cold front will move across the
region tonight. The low and cold front move offshore Friday
with high pressure returning for the weekend. High pressure moves
off into the atlantic Monday into Monday night. The next frontal
system approaches Tuesday with an associated cold front moving
across during midweek.

Near term until 6 am Friday morning
An area of low pressure will move north of the area, bringing a
cold front across the region late tonight and into early Friday
morning. This will result in several rounds of showers and
thunderstorms to develop across the area through the overnight
hours. Some storms could become severe, potentially producing
strong gusty winds and heavy rain.

Temperatures tonight will be in the mid to upper 60s.

Short term 6 am Friday morning through Friday night
Showers gradually end Friday morning with a return to dry
conditions for much of the area by afternoon. Lingering clouds
and possible shower could hang on across new london county in
the afternoon.

Nw flow behind the departing low and ahead of building high pressure
to the west supports gusty winds on Friday with gust between 25
to 30 mph. Temperatures on Friday will be in the upper 70s to
near 80 across the nyc metro area and mid to upper 70s
elsewhere.

There is a moderate risk of rip current development at atlantic
ocean beaches on Friday.

Long term Saturday through Thursday
High pressure builds in through the weekend with dry weather and a
good amount of sunshine for both days. Saturday could be on the
breezy side with lighter winds on Sunday. High temperatures near
average for Saturday, then a few degrees warmer for Sunday.

An upper ridge axis approaches from the west on Monday and should
help offset any rainfall trying to sneak in from the west well ahead
of the next low pressure system. Will leave in just a slight chance
of a shower thunderstorm for the afternoon in the city, nearby
suburbs, and points west. High temperatures again above normal.

A warm front out ahead of the low is progged to moves through
sometime either Monday night or Tuesday. Chance pops for this
period. Behind the warm front, a trough sets up INVOF the forecast
area on Wednesday, maintaining the threat of a shower or
thunderstorm. The system's trailing cold front is progged to pass
through late Wednesday night or Thursday. Will maintain slight
chance pop for this period.

Aviation 20z Thursday through Tuesday
A warm front continues to slowly lift north across portions of the
area this evening. Low pressure approaches from the west this
evening and tonight. A cold front moves across the area early Friday.

A warm front will continue to slowly lift north across the terminals
this evening. Showers and thunderstorms have started to move across
the nyc terminals allowing conditions to improve. However, away from
the rain, most terminals remain ifr or less, improvement to MVFR
thenVFR is likely with the rainfall.

The best chance of convection in the nyc metro lower hudson valley
is through 24z-01z. Some of these storms could produce brief ifr
conditions and gusty winds. Mainly MVFR conditions are expected
thereafter with any lingering showers or stray tstms. A return to
lifr lifr CIGS at kisp kgon kbdr khpn remains very possible
overnight.

Improvement back toVFR is expected on Friday behind a cold
frontal passage. Expected improvement around the 15z.

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.
