Synopsis for the long island waters and new york harbor.. High pressure over the waters tonight will be shunted southward tomorrow as a cold front approaches the area and moves through overnight. High pressure then rebuilds across the area through late week, then shifts offshore by late weekend ahead of a slowly approaching low pressure system.

406 pm edt Wed oct 18 2017

Synopsis
High pressure over the mid atlantic states will drift off the
eastern seaboard through Thursday, providing dry conditions and
above normal temperatures. A weak cool front will pass through
late Thursday, but dry conditions will prevail due to limited
moisture. Another area of high pressure will then build in from
the south and west Friday into the upcoming weekend, resulting
in continued dry and mild conditions.

Near term until 6 am Thursday morning
As of 400 pm edt... Clear blue skies and warm temperatures in
place across the region late this afternoon. Most locations have
warmed into the 65-70 degree range, which is around 10 degrees
above normal for mid october.

Clear skies will continue overnight, although with surface high
pressure shifting farther south and east there will be a light
persistent southerly breeze in some spots which will keep
temperatures milder in the mid to upper 40s. However, there will
still be favored locations where winds will decouple and
temperatures will drop into the upper 30s to lower 40s. Patchy
radiation fog will be possible in favored spots near warmer
bodies of water.

Short term 6 am Thursday morning through Saturday
Another warm day in store on Thursday, as south-southwest low
level flow increases as a weak cool front approaches from the
great lakes. Forecast soundings indicate good mixing to around
or even slightly higher than 925 mb, so breezy warm conditions
are expected. Highs should reach the upper 60s to lower 70s,
with just some patchy mid level clouds moving into the
adirondacks late in the day. Winds could gust to around 25 mph
from the late morning through afternoon hours, as the pressure
gradient increases.

The cool front will cross the region Thursday night, will
little more than just some mid level clouds, mainly north of
i-90. Very limited moisture to work with, so no precip expected.

Winds will shift to the w-nw behind the front, and will remain
somewhat persistent through much of the night, so temps will be
on the mild side.

Weak cold advection behind the front will lead to only slightly
cooler temperatures for Friday, with plenty of sunshine due to
a building ridge of high pressure both at the surface and aloft.

Temps Friday night will be a bit cooler than Thursday night due
to calm winds and clear skies resulting in good radiational
cooling. Sunny skies and well above normal temps expected again
on Saturday, as the ridge becomes firmly entrenched over the
region.

Long term Saturday night through Wednesday
High pressure builds offshore Saturday and Sunday with gradual
warming over our region. Stronger warm advection occurs Monday
into Tuesday with the development of a highly amplified phased
upper system and associated low level forcing. Good consensus
from sources of guidance for the development of this system but
as usual this far out in time, the details of timing, strength
and rainfall totals very much in question.

The increased low level forcing and deep moisture associated
with the system will result in increasing chances for rain
Monday through Tuesday. There are uncertainties as to the timing
of the deeper moisture and stronger forcing but the onset of
cold air advection and passage of the upper trough axis looks to
be generally toward Tuesday night or later. As usual, this far
out in time, changes and adjustments to the forecast are
expected periodically until we get closer to the event.

Highs Saturday in the mid 60s to around 70. Highs Sunday in the
upper 60s to lower 70s. Highs Monday with rain potentially
spreading into our region in the mid 60s to lower 70s. More
clouds and widespread rain should keep highs Tuesday in the 60s
but some upper 50s northern areas.

Aviation 20z Wednesday through Monday
Clear skies in place through the TAF period thanks to high
pressure centered over the mid-atlantic. Fog potential is a bit
unclear tonight. With the position of the high, a light
southerly breeze may persist overnight, and moisture will be
very shallow. On the other hand, localized river valley fog was
observed over the mid-atlantic last night under similar
conditions. For now, included MVFR br at kgfl and kpsf. Any fog
that forms should be very shallow and transient.

Wind directions this afternoon will vary from southerly to
westerly at around 5 kt, becoming light southerly or calm
overnight. Some possibility for llws toward 12z as winds at 2kft
increase to 20-30kt. Llws would be most likely at kgfl. Winds
will become south-southwesterly Thursday increasing to around
10 kt by the end of the TAF period.

Outlook...

Thursday night: no operational impact. No sig wx.

Friday: no operational impact. No sig wx.

Friday night: no operational impact. No sig wx.

Saturday: no operational impact. No sig wx.

Saturday night: no operational impact. No sig wx.

Sunday: no operational impact. No sig wx.

Sunday night: no operational impact. No sig wx.

Monday: moderate operational impact. Chance of shra.

Fire weather
Southwest winds will gust to around 25 mph on Thursday...

high pressure over the mid atlantic states will drift off the
eastern seaboard through Thursday, providing dry conditions and
above normal temperatures. A weak cool front will pass through
late Thursday, but dry conditions will prevail due to limited
moisture. Another area of high pressure will then build in from
the south and west Friday into the upcoming weekend, resulting
in continued dry and mild conditions.

Relative humidity values will increase to around 80 to 100
percent tonight, decreasing to minimum values of between 35 and
45 percent Thursday afternoon. Rh values will increase to around
90 to 100 percent Thursday night.

Winds will be southerly around 5 mph or less tonight, becoming
south- southwest increasing to 10 to 15 mph with gusts around 25
mph on Thursday. Winds will shift to the west at 5 to 15 mph
Thursday night.

Hydrology
No precipitation is expected through at least the weekend
thanks to persistent high pressure, with river stream flows
remaining at normal to below normal seasonal levels.

The next chance of rainfall arrives early next week, as a
widespread rainfall is possible associated with a slow-moving
frontal system. It is much too early for specific details, but
some heavy rain may occur in the Tuesday to Wednesday time
frame.

For details on specific area rivers and lakes, including
observed and forecast river stages and lake elevations, please
visit the advanced hydrologic prediction service AHPS graphs
on our website.
