Synopsis
A trough of low pressure will be in the area this evening. A
cold front will then slowly approach through Thursday. The
front moves across and southeast of the region Thursday night.

The cold 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 until 6 am Thursday morning
Showers and thunderstorms will be moving through the area as we
head into the early evening hours. Mid level shortwave lift will
shift through and interact with capes of 2000-3000 j kg with
the best lift exiting east by midnight. The biggest threat with
severe storms would be with wind gusts. There is also at least
a chance of flash flooding where the heaviest storms
concentrate.

The precipitation is expected to wind down from west to east
later this evening and there could be some patchy fog late with
a residual moist environment. Muggy overnight with low
temperatures above normal.

A moderate risk of rip current development remains into this
evening for the ocean beaches.

Short term 6 am Thursday morning through Thursday night
A cold front approaches on Thursday and passes through Thursday
evening. A pre-frontal trough probably sets up in the afternoon
across part of the tri-state area ahead of the cold front. This
along with shortwave lift and sufficient CAPE will bring shower and
thunderstorm chances mainly during the afternoon and evening hours.

Shear profiles support the potential of at least strong storms.

Regarding temperatures and heat indices, 850mb temps are forecast to
be around 17c afternoon. Surface winds will be mostly sw, and
perhaps even more westerly away from the coast. This would normally
allow surface dewpoints to lower a few degrees in the afternoon,
however with the presence of a pre-frontal trough and approaching
cold front, this could be offset somewhat.

There is a moderate rip current risk for Thursday.

Long term Friday through Wednesday
An upper level trough lifts north of the region on Friday. Upper
level ridging moves into the region this weekend and continue into
early next week. This is fairly 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, a cold front will continue moving southeast of
long island Friday and 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, other than some left over early morning showers on
Friday, dry conditions are forecast for Friday and 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 21z Wednesday through Monday
A trough of low pressure develops this afternoon ahead of an
approaching cold front with a chance of showers and
thunderstorms. Coverage of showers and thunderstorms will
increase late this afternoon, with MVFR or ifr possible in any
thunderstorm. Thunderstorm chances diminish later this evening
and overnight. Confidence in timing, placement and coverage
remains low.

Southerly winds increase to 10-15 kt with gusts to around 20 kt
possible at the nyc terminals during the afternoon. Winds
lighten from the SW this evening and overnight.

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.
