Synopsis
Jose will meander well southeast of the twin forks of long island
through tonight, then move slowly west on Friday. By the
weekend, high pressure builds over the area and remains in place
through next week as jose meanders offshore and slowly weakens.

Meanwhile, hurricane maria is expected to move off the
southeast coast and is being monitored closely for any potential
impacts to the northeast later next week. Please refer to
national hurricane center products for more details on tropical
systems jose and maria.

Near term until 6 pm this evening
Only minor updates this morning to reflect current temperature
and wind trends. Warmer temperatures this morning have led to
deeper mixing in the boroughs, with stronger winds being
reported at the nyc airports. Otherwise forecast remains on
track.

High pressure will continue to build into the region from the north
as upper ridging is enhanced from deep troughing over the western
states. Jose will meander well south and east of the twin forks of
long island today. Please refer to national hurricane center
products for more details on jose.

The tightest pressure gradient will reside across the twin forks of
long island and southeast connecticut today, and this is where gusts
30-35 mph will be possible. Cloud shield associated with jose will
continue to bring mostly cloudy skies to at least the eastern half
of the region with a better chance at seeing partly cloudy skies
from the city north and west. Subsidence on the backside of jose
will keep rain bands just to the east of the forecast area through
this evening.

High temperatures will vary across the area with middle to upper 70s
across eastern connecticut and long island due to more extensive
cloud cover. Further west, highs will warm into the lower and middle
80s.

Dangerous rip currents will continue at atlantic ocean beaches
today.

Short term 6 pm this evening through 6 pm Friday
Jose will begin to slowly move westward and weaken late tonight into
Friday as the system gets caught in weak steering flow. The deep
ridging to the west is progged to be highly anomalous so the
westward motion will only bring a weakening jose a bit closer to the
southeast coast of long island. This could bring a few rain bands
back towards the twin forks and southeast connecticut. Will carry
slight chance pops tonight through Friday afternoon, with a higher
chance of these rain bands remaining offshore due to dry air and
subsidence. Thickest cloud cover and strongest wind gusts, 30-35
mph, will continue across eastern sections tonight into Friday.

Again, please refer to national hurricane center products for more
details on jose.

Otherwise, upper ridging and high pressure will remain to the north
and west. Dry conditions are forecast for the western two thirds of
the region. Temperatures will be above normal for much of the area,
except for eastern long island and southeast connecticut where highs
on Friday will only reach the upper 60s and lower 70s due to
extensive cloud cover. Elsewhere, highs will reach the upper 70s and
lower 80s.

Dangerous rip currents are likely to continue at atlantic ocean
beaches on Friday.

Long term Friday night through Wednesday
With tropical cyclone jose lingering about 200-300 miles offshore of
montauk, gusty winds and showers may be possible across eastern long
island and connecticut through the weekend. Apart from eastern areas
where clouds may prevail, temperatures will be closer to normal
while humidity will be at comfortable levels as dry air advects
southward around the west side of jose. By early next week, the
system weakens significantly and high pressure settles across the
area, leading to above normal temperatures. Thereafter less
confidence exists in the forecast, as the national hurricane center
has hurricane maria continuing northward off the southeast coast.

Given the forecast path, beach hazards will likely increase once
again with building surf and the possibility of dangerous rip
currents well ahead of the system. What is less certain is how much
precipitation will be possible between the approaching tropical
system and a trough to the west, or how strong winds will be across
the area by mid to late week. Please continue to monitor national
hurricane center forecasts regarding the track and intensity of
maria.

Aviation 14z Thursday through Monday
Tropical cyclone jose will meander off the southern new england
coast through Friday. It will push mid and upper level moisture
from east to west across the eastern half of the terminal area.

Vfr all terminals. Kgon may be in and out of MVFR for a few
hours.

Gusts increase today, generally 20-30 kt, with the highest
across the eastern terminals.

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.
