Synopsis
High pressure remains over the region through Monday.

Strengthening low pressure heads northward into southeast
canada Monday night into Tuesday with its associated cold front
approaching the region. The cold front will slowly move into the
region Tuesday into Tuesday night. The front will become nearly
stationary Wednesday before gaining more eastward movement
Wednesday night, moving east of the region by early Thursday.

An upper level disturbance follows for Thursday before weak
high pressure settles in late next week.

Near term until 6 am this morning
130 am edt update - minor update for recent trends in temps and
dew point, otherwise fcst is on track.

Patchy localized radiation fog is likely in the valleys and
pine barrens, but believe is will not be extensive enough to
included in the forecast grids - at least at this time.

Short term 6 am this morning through 6 pm Monday
High pressure will be situated just offshore with another dry and
mostly sunny day as some cirrus filters the sunshine at times.

High temperatures will be above normal, but likely a couple of
degrees cooler than yesterday in most cases.

Low level moisture increases tonight with a light SE flow.

Models suggest stratus moving in with better chances of at least
a broken deck occurring west of eastern LI and ct. This leads
to a partly to mostly cloudy Monday. There appears to be enough
isentropic and low level lift for a chance of showers in the
afternoon. Showers would be light as mid levels remain dry.

Better chances are once again west of eastern LI and ct. In
spite of the clouds and onshore flow, highs will still range
mostly 70-75.

Long term Monday night through Saturday
Deep upper level trough with strong meridional flow will be
approaching the region Monday night as the jet dives into the
southeast. The trough will stretch from florida through southeast
canada Tuesday into Wednesday. At the surface, the parent low
pressure area moves from the great lakes Monday night into northern
quebec by early Wednesday. With all the southerly steering flow,
the cold front will have little eastward movement, coming to
almost a halt Wednesday before gaining more eastward movement
Wednesday night. This will be in response to another upstream
diving shortwave that is forecast to move NW to SE from the
north central us into the carolinas. Thereafter, the upper level
trough axis moves across Thursday while the surface cold front
moves farther east into the atlantic. Ridging and high pressure
return but will be of lesser magnitude late next week.

In terms of weather, rain showers will become more widespread Monday
night into Tuesday, lingering into Tuesday night. Bulk of rain
expected Tuesday afternoon through Tuesday night. The front nearly
coming to a halt Wednesday will keep showers in the forecast
Wednesday before tapering off Wednesday night. The region could even
still see some showers Thursday with the upper level cold pool
associated with the trough axis moving across. Models are
hinting at this with their small QPF as the flow becomes more
westerly. Then, mainly dry weather is expected Thursday night
through next Saturday.

Winds could potentially be an issue Tuesday through Tuesday
evening. There is a low level jet ahead of the cold front and
the models have pretty good agreement with the magnitude being
near 50kt Tuesday into Tuesday night. With the deep trough and
high precipitable waters forecast, near 1.75 to 1.8 inches, very
high (above 90th percentile) for this time of year according to
okx sounding climatology, heavy rain will be possible at times,
especially in any thunderstorms. The thunderstorm chances will
be there with strong omega and low level instability present
within the model guidance. Low level instability is diagnosed
from model CAPE fields between 100 and 300 j kg. S-se winds of
20-25 mph with gusts 30 to 40 mph are looking more probable
especially along the coast with locally higher winds possible
with any heavier showers or thunderstorms that could potentially
bring down higher winds with downward momentum transport.

Temperatures forecast of lower 70s for highs Tuesday and upper
60s to 70 for highs Wednesday. Highs more in the 60s for the
rest of the days in the long term.

Aviation 06z Sunday through Thursday
Vfr expected through at least 03z Mon with high pres ohd gradually
moving east through tonight.

There is a low chance of MVFR-ifr fog through 12z at
kswf khpn kgon kisp.

Light and variable winds through the remainder of the night.

S SE winds 8-12 kt develop later this morning and afternoon with
seabreeze enhancement at coastal terminals.

Aft 03z tonight, the second night of onshore flow, may start
seeing indications of fog and or stratus development, however
timing and extent of MVFR ifr conds is uncertain attm.

Outlook for 06z Monday through Thursday
Late Sun night-mon MVFR ifr possible in stratus and fog into
mon morning, thenVFR. S SE g20 kt Mon aftn.

Mon night-tue Potential a period of S SE g30-40 kt with llws
ssw 45-55kt@2kft for coastal terminals. Could occur during
morning push. MVFR ifr developing in -radz Monday night,
continuing with shra and low prob sparse tsra Tuesday.

Tue night-wed Ifr possibly continues in showers tue
night... Improving to MVFR wed.

Wed night-thu Vfr, with iso-sct MVFR in shra. W NW wind.

Marine
Tranquil conditions on the waters overnight through Sunday
night as high pressure ridge with a weak pressure gradient
shifts offshore and slowly drifts out to sea. Onshore winds pick
up through the day on Monday, but conditions will remain below
advisory criteria.

Sca conditions become more probable Monday night on the ocean and
likely Tuesday through Thursday on the ocean. Gales will be
possible Tuesday and Tuesday night, mainly across the ocean with
sca conditions being likely on non-ocean waters. For Wednesday
through Thursday, the ocean SCA conditions are mainly due to
lingering high seas.

Hydrology
Localized minor urban flooding will be possible Tuesday into
Tuesday night but otherwise no other hydrologic problems are
expected with the storm total rain of 1.5 to 2.5 inches mostly
falling Monday night through Wednesday. Locally higher amounts
will be possible.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
