Synopsis
Weak low pressure passes to the north today bringing a cold
front south of the region. High pressure builds in for tonight
and Sunday. Then a series of lows will pass through the area
through mid week.

Near term until 6 pm this evening
Increasing clouds are expected through the remainder of the day
as the next vorticity maximum passes across new england and a
weak cold front approach from the nw. The cold front will pass
through from north to south into the evening.

Some snow showers are possible this afternoon across the
interior. Drier low levels across the region should prevent any
widespread activity, but some of these snow showers could
translate towards to the coast by early this evening as the cold
front moves through. Do not anticipate any accumulation other
than possible a dusting if a snow shower does occur.

Breezy westerly winds are forecast today with gusts 20-25 mph at
times. High temperatures will range from the lower and middle
30s inland to the upper 30s near the coast.

Short term 6 pm this evening through 6 pm Sunday
A few flurries may be lingering into the early evening hours if
the cold front is slower to push through. At this time will keep
the evening dry. Height rise tonight through Sunday as the flow
becomes more zonal. A dampening shortwave will be moving into
the weak upper ridge late Sunday and Sunday night, and pass
through Sunday night.

Long term Sunday night through Saturday
A weakening shortwave passes through Sunday night into Monday.

Have lowered the probabilities slightly as the shortwave is
weakening and flat, with little moisture. Warmer air will be
pushing into the region, and as the warm air lifts north of the
cold surface air a period of freezing rain, some ice pellets and
snow will be possible. Too early for specific details on this
light precip event.

Thereafter, models in fairly good agreement with the broad bu
shallow northern stream trough approaching the region on
Tuesday and sliding through during the midweek. At the surface,
the primary low pressure system rides through quebec ontario
with trailing cold front approaching the region Tuesday night.

Overall, appears to be mainly a light QPF event for the Monday
night into Tuesday evening period, due to limited interaction
between northern and southern stream. Thermal profile suggests
precip would be mainly liquid, but could be dealing with
freezing rain across interior Monday night as cold air
typically has a tough time scouring our in this setup.

Upper trough swings through the NE Tue night into Wed with a
glancing shot of modifying arctic air in the wake of the cold
front for Wed thu.

Upper flow flattens and even becomes a bit ridged for Thursday
ahead of the next northern stream trough digging into the upper
plains, which should allow for a moderation in temps ahead of
next potential frontal system.

Aviation 18z Saturday through Thursday
A cold frontal passage occurs this evening.

Ceilings around 3500 ft can generally be expected through the
taf period for the city terminals, coastal connecticut and long
island. To the north however, there is a higher probability for
ceilings to settle around 3000 ft for this afternoon and
evening. MVFR has therefore been forecast for those areas.

There is a chance for snow showers through approximately 00z.

Vcsh have been included in the tafs, with coverage expected to
be mainly isolated at this time.

Winds in the 250-270 true range will veer to the northwest
behind the cold front tonight. The winds will continue to veer
to the north on Sunday.

Outlook for 18z Sunday through Thursday
Rest of Sunday Ifr possible overnight with snow or a light
wintry mix possible. Variable wind direction with speeds below
10 kt.

Monday Light rain possible along the coast in the morning,
with a light wintry mix possible elsewhere. BecomingVFR.

Westerly flow developing.

Tuesday Areas of MVFR possible with southwest flow.

Wednesday Vfr with northwest flow 20-25 kt.

Thursday Vfr with light winds becoming southerly.

Marine
Gusty small craft winds are likely across all the forecast
waters today into early this evening as a rather tight pressure
gradient moves through the waters as low pressure moves into the
atlantic and high pressure builds to the west. Gusty winds may
linger into this evening on the ocean waters. Ocean seas may
remain around small craft levels into the first part of tonight.

So, the advisory remains into this evening on the ocean.

The next chance for SCA conditions will be late Tuesday Tue eve
ahead of approaching cold front, but higher likelihood of
widespread SCA Tuesday night through Wednesday night with tight
pressure gradient and strong CAA in wake of cold front. Gales
are possible during this time frame.

Hydrology
No significant hydrologic impacts expected.

Nyc NOAA weather radio station kwo-35 (162.55 mhz) is off the

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.
