Synopsis
High pressure will build into the region today, and then
settle to the south and east Monday through Tuesday. A frontal
system approaches Tuesday night and crosses the region
Wednesday. Canadian high pressure then builds in through
Saturday.

Near term until 6 pm this evening
Vigorous shortwave pivots northeast of the region early this
morning with associated cold front pushing well offshore. In its
wake, zonal upper flow develops with high pressure building in
from the west.

Deep NW flow and subsidence will result in a sunny, comfortably dry,
and seasonably warm day today. Highs generally in the lower to
mid 80s. Late day sea breeze possible along the immediate south
coasts.

There is a moderate risk for rip current development for E li
beaches due to lingering 3 ft @ 6-7 sec swells.

Short term 6 pm this evening through Tuesday
Zonal upper flow continues into mon, and then begins to back a bit
Tuesday ahead of a longwave trough digging into the great lakes.

At the surface... High pressure gradually translates to the south and
southeast tonight into Monday morning. Good radiational cooling
conds tonight, with lows in the 50s across far outlying areas. 60s
to around 70 elsewhere.

As the high builds south and east, heat and humidity will build into
the region Monday into Tuesday. Highs will generally be well into
the 80s to around 90 on Monday, and upper 80s to lower 90s for
Tuesday. Low prob of heat advisory for portions of the nyc nj metro
on Tuesday as humidity levels climb.

Models are indicating potential for isolated diurnal convection
(along sea breeze boundary or hills) on Tuesday as instability
increases and convectively induced vort energy rotates around the
upper ridge. Low predictability on convective details at this
point.

Long term Tuesday night through Saturday
Longwave trough digs into the great lakes Tue into Tue night and
then slides into the NE us for the mid to late week. An associated
frontal system interacting with a sub-tropical airmass will bring
the next chance for organized shower and TSTM activity Tue night
into wed. Low predictability on the convective details at this
point... Contingent on timing of front forcing with diurnal
instability.

Then a significant cool down expected for the end of the week as the
long wave trough settles into the NE us, and canadian high pressure
slowly builds SE from central canada through the midweek. This
will provide mostly sunny, dry and unseasonably cool conditions to
end the week into the weekend.

Aviation 12z Sunday through Thursday
Following a weak cold frontal passage, high pressure will build
in for the remainder of the TAF period.

Vfr through the TAF period. Winds will be near 10 kt or less.

Flow becomes more NW into this morning and then w-sw in the
afternoon with the more SW flow at coastal terminals,
particularly kjfk. Flow generally becomes more NW tonight.

Outlook for 06z Monday through Thursday
Late tonight-Tuesday morning Vfr. SW gusts to near 20kt
Monday late afternoon to early evening.

Tuesday afternoon-Wednesday A chance of showers and
thunderstorms with MVFR or lower conditions possible. SW gusts
20-25kt Tuesday afternoon through Tuesday night.

Wednesday night-Thursday Vfr.

Marine
Sub-sca conditions expected through Tuesday afternoon as high
pressure traverses southeast through the waters.

Winds and seas will increase ahead of a cold frontal Tuesday
into Tuesday night. Marginal SCA gusts possible Tue aft tue
night with ocean seas building to SCA levels Tue night wed.

In the wake of the front, winds and seas are expected to fall
below SCA levels for late week as high pressure slowly builds
towards the area.

Hydrology
Dry conditions through Monday.

Hydrologic impacts from potential showers and thunderstorms
Tuesday into Wednesday are uncertain at this point.

Ny... None.

Nj... None.

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.
