Synopsis
A cold front will slowly approach through Thursday. The front
moves across and southeast of the region Thursday night. The
front will move farther southeast of the region Friday into the
weekend as high pressure builds in from the north. Weak low
pressure areas and a frontal system approach early into the
middle next week.

Near term through tonight
Several hazards today. The first is the severe threat, which right
now looks to be focused on the afternoon and evening. Heat and
humidity will result in an unstable airmass, with surface based cape
approaching 3000 j kg at times. Gently falling heights could trigger
activity at any time, but the best focus is after 18z when a
shortwave approaches. This will enhance both lift and shear,
allowing for better organization of cells. The primary threat will
be damaging winds, but 0-1 km EHI in the 1-3 range and veering low
level winds supports an isolated tornado threat. There is also a
hail threat is the best organized storms.

Limiting factors for convection will be any activity prior to the
peak threat time working over the atmosphere or limiting
instability. This is entirely possible with CIN eroding quickly this
morning and falling heights.

The second hazard is heat. Dewpoints are already overperforming,
with islip at 76 this morning. In addition, it does not seem likely
that conditions will improve before the cold front comes through,
which is not until Thu night. Based on this, a heat advisory was
issued for nyc and the adjacent portions of nj and long island. It
is possible that this advisory will need to be expanded based on
what happens today what is expected on thu, as many areas are just
forecast to remain below the 95 degree heat index threshold.

There is the potential that areas in the advisory fall short today
and therefore need to be canceled for thu. Widespread convection
could impact MAX heat indices today.

The third hazard is a high rip current risk. It will primarily be
moderate today, but late this afternoon and evening southerly flow
builds seas to around 5 ft, requiring the issuance of a high risk.

Finally, there is an isolated flash flood risk where the heaviest
storms concentrate. This will likely be near boundaries with storm
motion otherwise east around 10 kt.

The precipitation is expected to wind down from west to east
late this evening as the upper support exits. There could be
some patchy fog late with a residual moist environment.

Short term Thursday
The models have backed off on thunderstorm chances for the bulk of
thu, but with the cold front still on the doorstep, at least slight
chances have been retained, particularly in the afternoon. Dewpoints
are modeled to be a bit lower with more of a westerly component to
the wind. However, the models have been a bit low in general, so as
previously mentioned a more humid forecast has been issued.

There is a moderate rip current risk for thu.

Long term Thursday night through Tuesday
Upper trough moves near and eventually northeast of the region
Thursday night into start of weekend. Upper level ridging moves
across for the weekend into early next week. Solution consistent
between GFS and canadian models but ECMWF model breaks off a piece
of the trough and keeps it near region as weak upper level low for
the weekend. For next week, the ridge eventually moves east of the
region with a weak trough approaching from the west.

At the surface, the cold front will be within the region to start
Thursday night and by Friday morning should be southeast of long
island. The front will continue moving southeast of long island
going into the weekend. GFS and canadian models likewise show a more
steady front movement southeast of long island while ECMWF shows a
little slower movement and closer proximity of low pressure to the
region along the front.

For weather, a continued chance of showers and thunderstorms
Thursday evening but would expect thunder chances to decrease with
the more northerly flow developing behind the front and overall
instability trending downward. Showers chances linger into Friday
morning. Then, dry conditions are forecast for the much of the
weekend. Depending on how low pressure trends along the front to the
south and a frontal system approaching from the west going into
early to middle of next week, there could be a return to rain in the
forecast. Currently, it seems this scenario is more of a low end
possibility, so limited rain to slight chance, with mainly dry
conditions anticipated.

Temperatures overall forecast to be slightly below normal.

Aviation 09z Wednesday through Sunday
A warm front passes this morning. A trough of low pressure develops
this afternoon ahead of an approaching cold front, with showers and
thunderstorms becoming likely.

MainlyVFR this morning, except MVFR or even ifr in patchy stratus,
or an isolated shower or thunderstorm. Coverage of showers and
thunderstorms will increase this afternoon, with MVFR or ifr
possible in any thunderstorm. Thunderstorm chances diminish later
this evening.

Southerly winds will be less than 10 kt early this morning,
with winds light and variable at the outlying terminals. Winds
increase to 10 to around 15 kt late this morning, with gusts to
around 20 kt possible at the nyc terminals during the
afternoon. Winds lighten from the SW this evening.

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.
