Synopsis
High pressure builds into the region today, and offshore on
Thursday. A warm front moves north of the region Thursday
night. Bermuda high pressure then dominates Friday into
Saturday before a cold front moves through Sunday into Sunday
night. The front may then linger just south of the region early
next week.

Near term through tonight
Forecast still on track this morning.

A 1024 mb high was centered over WV late this morning. The high
will drift eastward through tonight. Sct flat CU were starting
to develop in the higher elevations and should become more
widespread this afternoon.

Below normal highs are forecast, mainly in the upper 70s to near
80 degrees. Bumped up highs a couple degrees on long island
since sea breeze (if any) will be arriving late.

Short term Thursday
As the high drifts ewd over the atlantic, the winds will begin
to respond to lowering pres over SRN ontario. This flow, coupled
with the sea breeze circulation, should produce windy conditions
along the coasts by late in the day. Otherwise, all other areas
should have a sly breeze at least. The latest modeling from the
nam, GFS and ECMWF keeps any frontal systems N of the cwa, so
pcpn has been removed from the fcst. Humidity will increase due
to the increasing flow off the ocean, and temps will warm to aoa
average as a thermal ridge begins to build in. The 00z models
have around 14-16c at h85 by the end of the day. If things
unfold as currently expected, dangerous rip currents will be
possible, particularly in the late aftn and eve, requiring a
high risk fcst.

Long term Thursday night through Tuesday
The main trend in the long term is for warmer and more humid
conditions to take shape over the tri-state.

On the larger scale, a shortwave passes to the north Thursday night
followed by rising heights and western atlantic ridging taking shape
Friday into Saturday. This ridge axis moves offshore Sunday as the
next shortwave trough moves across new england through Sunday night.

Another shortwave trough may follow early next week. Models and
ensembles are in good agreement overall on the large scale through
the weekend, then diverge a bit with the handling of any shortwaves
early next week.

At the surface, a warm front moves north of the region Thursday
night. Bermuda high pressure will then influence the weather Friday
into Saturday before a cold front moves through Sunday into Sunday
night. There may be weak surface trough development to the NW of nyc
each day before the cold front moves through Sunday. This front may
then linger to the south early next week.

Shower and thunderstorm chances appear slim Thursday night and
mainly to the north and west of nyc. The same holds true on Friday
into Saturday as ridging and heights build aloft. The best chance of
any convection is mainly from the city north and west. Shower storm
chances increase a bit across the entire area on Sunday with the
passage of the cold front and approaching shortwave. Drier
conditions return on Monday with the next chance at showers and
storms on Tuesday.

Temperatures Friday and Saturday will be in the upper 80s with
increasing humidity levels. A few 90 degree readings are also
possible in the nyc metro and NE nj. MAX heat indices look to stay
in the lower 90s both days at this time at these locations, with
upper 80s elsewhere. Closer to the coast, onshore flow will keep
highs in the lower to middle 80s. Temperatures should be a bit
cooler on Sunday in the lower and middle 80s due to increasing
clouds and higher coverage of showers storms. Highs should gradually
fall back closer to normal early next week.

Aviation 16z Wednesday through Sunday
High pressure builds into the region through today and offshore
on Thursday.

Vfr conditions are expected through the TAF period.

Wnw winds will back to the s-sw through the afternoon with gusts
to 15-20 kt. Winds diminish tonight before increasing further
on Thursday.

Ny metro enhanced aviation weather support...

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.
