Synopsis
High pressure will remain over new england through tonight and
then drift offshore on Tuesday. A cold front gradually approaches
Tuesday night into Wednesday and passes through the region
Wednesday night into early Thursday. High pressure returns
briefly Friday before another cold front passes through Friday
night into Saturday. High pressure builds towards the northeast
Saturday with a wave of low pressure possibly impacting the area
on Sunday.

Near term until 6 pm this evening
Pockets of stratus are likely early this morning. The stratus
may be most widespread across portions of the nyc metro and long
island and more scattered across southern connecticut. Model
time heights in bufkit seem to have a decent handle on this
moisture associated with the stratus and indicate that it will
begin diminishing 12z to 15z.

Otherwise, high pressure will remain over new england as an upper
low moves towards the canadian maritimes. The interior will likely
have mostly sunny skies through the day with scattered stratocumulus
further south near the coast.

Highs today will be several degrees below normal under a NE flow and
850 mb temperatures averaging around 11c. Highs will be in the lower
to middle 70s.

There is a high risk of rip current development at the atlantic
ocean beaches through this evening.

Short term 6 pm this evening through 6 pm Tuesday
Heights aloft rise tonight as the upper low continues to track over
the canadian maritimes. Surface high pressure will remain in place
over new england. Low level moisture appears less than the last
several nights. There could still be some scattered clouds early
Tuesday morning, but overall decent radiational cooling conditions
are anticipated. Lows will be in the lower 50s inland and across the
long island pine barrens and the middle and upper 50s most
elsewhere. Lows in the nyc metro will be in the lower 60s.

Upper ridge axis moves over the northeast on Tuesday with the
surface high pressure drifting off the new england coast. The ridge
axis should be east of the area late in the day and as this occurs
middle and upper level moisture should start to increase. Mostly
sunny conditions in the morning will become partly to mostly cloudy
late. Highs will continue below normal in the middle and upper 70s.

There is a moderate risk of rip current development at the atlantic
ocean beaches through this evening.

Long term Tuesday night through Sunday
Upper level ridge axis shifts east of the area Tue night but blocks
a closed low over ontario canada from progressing eastward, forcing
it north into hudson bay and then consolidating with another piece
of upper level energy from western canada. Troughiness will remain
in place over the northeastern quarter of the country for the
remainder of the long term period, although with the parent low
lifting further north into canada much of the associated energy will
also remain north of the area. In fact, by Saturday the local area
is expected to be on the southern edge of the westerlies.

This will provide mostly benign weather through next weekend.

However, shortwave energy and its associated sfc cold front will
approach from the ohio valley Tue night and wed, moving through
the tri state area Wed night into early thu. Best chance for
pcpn is in areas N and W of nyc as all meso and global models
are indicating a weakening trend as it moves through. There is
some elevated instability present after 00z Thu so have
maintained schc thunder in the forecast until the cold FROPA thu
morning. Humidity levels will increase ahead of the front with
muggy conditions briefly returning.

High pres then builds to the south through Fri although another
cold front will be approaching from the west. This front appears
to pass through dry with all of the upper level energy passing
to the north. Depending on how far south of long island this
boundary pushes will determine whether we are impacted by a
weak wave of low pres on sun. Have introduced chc pops for now,
but this is highly uncertain.

Aviation 08z Monday through Friday
High pressure will remain over new england through Monday night
before departing to the east on Tuesday.

MVFR ceilings have developed over the north shore of long
island and spread west into klga, kteb, and spread south into
kisp, so have added tempo group to these terminals for MVFR
ceilings. MVFR ceilings also spreading northward from new
jersey coastline. Thinking this will spread into the rest of the
city terminals, so added tempo group here as well. Winds have
become more northerly for many of the terminals.

This pattern will keep the area under a ne-e flow during the
time period with backing to the NE tonight and then veering more
to the E as the day progresses on Monday. Outside of a few
gusts into the teens this evening winds will be 10-15 kt at the
coastal terminals and 5-10 kt at the inland terminals.

Outlook for 06z Tuesday through Friday
Mon night-tue Vfr.

Wed MVFR or lower possible in showers and thunderstorms.

Thu MainlyVFR. Morning showers possible.

Fri Vfr.

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.
