Synopsis
A nearly stationary front will sink to the south tonight, and
remain just south through Tuesday. Weak low pressure will also
approach on Tuesday, and pass south Tuesday night. High pressure
will build in for Wednesday and Thursday, and shifts offshore
Thursday night. A low pressure system will approach from the
central states Thursday night, and impact the region Friday and
Saturday. High pressure will return for Sunday.

Near term /until 6 am Tuesday morning/
The front at 20z bisected the area, running from the lower half
of nyc to near groton ct. As a wave of low pressure develops
east of new england this evening, the front should sink to the
south, with winds becoming variable and then settling in from
the east late. This may bring somewhat drier air in initially,
but then with light winds and nearly saturated low levels, dense
fog is likely to develop, especially across southern ct and long
island where a dense fog advy has been issued. Rain approaching
from the west ahead of the next weak wave of low pressure may
prevent the fog from becoming dense farther west, but this
remain uncertain.

Lows tonight should range from the mid 40s INVOF nyc, to the
lower 40s most elsewhere, to the upper 30s across most of
southern ct.

Short term /6 am Tuesday morning through Tuesday night/
Rain is likely over the area in the morning as a mid level
impulse moves across. There is some elevated instability, enough
to enhance rainfall rates but not quite enough for a mention of
thunder. Then we should see a relative lull in precip until
a weak low moves off the mid atlantic coast Tue evening and its
associated upper trough move across. Once again there could be
enough elevated instability to enhance rainfall rates in the
evening, especially per the NAM which may be too unstable aloft,
so once again did not mention thunder. Also expect fog to
redevelop Tue night, though with the air mass not quite as
saturated and more of an offshore wind component, dense fog
appears less likely.

Highs on Tue should be 50-55 from nyc west, and in the upper
40s to near 50s most elsewhere. Lows Tue night should range from
40-45 nyc metro and long island, to the upper 30s inland.

Long term /Wednesday through Monday/
Typical spring pattern during this period with a deep closed low
emerging into the central us for the midweek... And then slowly
translating to the east coast by late week/weekend. The pattern then
repeats itself with another deep closed low emerging into the
southern plains by early next week.

Locally a northern stream trough over the region Wednesday slides
east Thursday... With model sensitivity and forecast challenge in the
interaction of the central plains closed low with a northern stream
shortwave over the ohio valley/great lakes Friday before it slide to
the east coast Saturday. Appears to be increasing agreement in
gefs/eps and operational gfs/ecmwf/gem on the opening shortwave
staying detached/far enough south for associated low pressure to
approach the mid atlantic and track over or just south of the region
fri/sat. Since this is still 4-5 days away will have to monitor this
interaction... As the low track could trend north if the interaction
w/ northern stream increases.

A low pressure system tracking to the south of the region would
spell potential for a period of wintry precip to start... A wind
swept rain... And at least minor coastal flood concerns fri/sat.

Farther north development/intensification would spell lesser
potential and duration of wintry precip, rain or coastal flooding.

Before then dry and seasonably mild conditions expected Wed and thu
as canadian high pressure builds into the region. In the wake of low
pressure... Generally dry and mild conditions expected sun/mon with a
generally zonal upper flow and pac airmass overspreading the area.

Aviation /20z Monday through Saturday/
A warm front will remain in the vicinity of the terminals this
afternoon.

Expect low stratus with periods of fog through the forecast period.

Cigs may improve to MVFR for a period this afternoon/evening,
however overnight, they are expected to fall back to ifr or
lower. Visibilities have improved toVFR in most spots. This
too should only last through the afternoon/evening, then vsbys
fall back below ifr or less as fog re-develops. There is a
chance that vsbys fall to 1/4 mile or less, however will leave
out of the tafs for now and will monitor through the evening.

Winds will remain less than 10 kt through the afternoon and
evening, before falling to light and variable overnight. Some
locations may even become calm.

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.
