Synopsis
Weak high pressure will build in for today. A warm front
approaching late tonight into Tuesday will briefly stall across
the area as weak low pressure moves along the front. A cold
front moves through Tuesday night. Weak high pressure is then
expected for Wednesday with a surface trough on Thursday, then a
cold front moving through Thursday night into Friday morning.

Weak high pressure then dominates through Saturday morning with
a couple of systems potentially affecting Saturday afternoon
through Sunday.

Near term until 6 pm this evening
Minor update to clear clouds faster per recent satellite
imagery. Otherwise forecast remains on track.

Brief deep layer ridging will build into the region, with
subsidence allowing for mostly sunny skies. Although
temperatures will continue to be above normal, the post-frontal
air mass will be about 5 to 10 degrees cooler than Sunday's
highs, generally reaching the 70s to lower 80s. Expect sea
breezes to develop along coastal areas later in the day as
northwest flow slackens.

Short term 6 pm this evening through Tuesday night
Warm advection steadily begins to increase into tonight with the
approach of a short wave trough and attendant surface low.

Increasing cloud cover will maintain above normal lows in the
50s across outlying areas, to lower 60s in the more metropolitan
areas.

Thereafter, a first round of showers is expected as a weak
vorticity maximum moves through. A brief lull into the early
evening may occur. There is then significant uncertainty as to
where the warm front will progress during the evening, though
recent deterministic runs have trended slightly farther north,
placing northeastern nj and potentially portions of nyc and the
lower hudson valley into the warm sector. Hi-resolution
scenarios have been hinting at more significant convection
developing on the cold front, which may be enhanced if a decent
amount of clearing can occur in the wake of the initial shower
activity. Flow will be backed in the vicinity of the warm
frontal boundary, and with northwest flow aloft remaining
strong, will lead to SRH values not often seen here, and deep
layer bulk shear values around 50-60 kt. Additionally, mid level
lapse rates should be around 6.0-6.5 c km. The progression of
the warm front will need to be closely monitored, as there is
certainly potential for supercells in the vicinity of and to the
south of the warm front. Otherwise, a brief period of heavy
rainfall is possible as the cold front moves through, with
everything then quickly clearing after about midnight. Lingering
cloud cover will once again lead to overnight lows that will be
above climatological normals.

There will be a moderate risk for rip currents at the atlantic
beaches for Tuesday.

Long term Wednesday through Sunday
Weak high pressure replaces a weak low exiting east on Wednesday.

Models seem to agree that it's fairly dry above 850mb and with nva
dominating through most of the day. Shortwave energy and a surface
trough approach late in the day and may be enough to trigger a
shower or thunderstorm mainly over the western half of the tri-state
area. Chances increase and spread east Wednesday night with these
features moving in along with deepening moisture. The temperature
forecast is a little tricky, but it appears there's building
convergence towards the warmer side of guidance during this period.

For Thursday the trough exits east in the morning, but thermal
troughing appears to gain strength inland ahead of the next cold
front. Showers tstms possible, but mainly in the afternoon and more
so at night. Still too early to be certain, but potential shear and
cape values could aid in strong storms should tstms occur.

Timing for the cold front appears to be either late Thursday night
or Friday morning. Will leave in low pops Friday morning to cover
this uncertainty, but will then go with a dry weather in the
afternoon. A zonal flow and a weak surface high then probably
maintains dry weather Friday night into Saturday morning. A wave of
low pressure may then form along a stalled boundary to our south and
bring chances of showers and storms Saturday afternoon and night.

The next cold front then brings more chances of showers and storms
on Sunday.

High temperatures from Thursday on are expected to be above
normal.

Aviation 10z Monday through Friday
High pressure builds today behind a cold front.

Vfr forecast through the the TAF period.

Winds have shifted to the NW behind the cold front, with speeds
remaining under 10 kt. Some outlying terminals could go light
and variable early this morning. Winds veer to the N and ne
this morning and then remain northerly into the afternoon around
10 kt. S-se seabreezes are expected for south coastal terminals
in the afternoon. Winds diminish this evening.

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.
