Rapidly deepening low pressure lifts north across the area this
evening and then tracks slowly across new england late tonight
through Thursday. High pressure will build into the region Friday,
remaining through the weekend. Another frontal system affects
the area Monday night through Tuesday, followed by high
pressure for the mid week.
Near term through Thursday
A very dynamic system will feature a coupling upper jet structure,
as a frontal wave undergoes explosive coastal development this
evening into the overnight. Models are in good agreement with
the overall evolution and track with subtle timing and intensity
issues. The southern branch jet energy pivoting off the mid
atlantic coast this evening takes the upper trough negative and
eventually closes off a new upper low across new england by
Moderate to heavy frontal band rains will work across the area
this evening and then transition to comma head rains as the low
wraps up. This will result in widespread rainfall amounts
of 2 to 3 inches, but possibly as high as 3 to 4 inches in
banded rain to the north and west of the low track. The low has
continued to trend north and west the last couple of days, with
the operational suite now in close agreement of a track across
western sections of long island and connecticut. This would keep
the axis of heaviest rainfall across the lower hudson valley,
sw ct, and northeast nj. Still though, the frontal band,
subtrop moisture, and anomalous upper jet (3 to 4 sd), all point
to heavy rain both with the warm conveyor belt ahead of the
deepening low and in the wraparound.
Gridded FFG values for NE nj are 2 to 2 1 2 inches. Thus, a
flash flood watch remains in effect for NE nj. Elsewhere, there
is a lower probability of flash flooding for urban, poor
drainage, and low lying areas.
Much of the rain falls in 6 to 8 hour window and then wraps up
between 10 pm and midnight western sections, to as late 2 am
far east. Comma head rains may linger across northern portions
of the lower hudson valley and interior southwest ct several
Additionally, a robust LLJ on the front end and back side of
the low this evening may briefly produce 40 to 50 kt gusts. The
best chance may be on the back side of the low with a sting jet
signature. A prolonged wind advisory level event then follows
for the remainder of the night into Thursday with frequent gusts
up to 40 kt. Thus, a wind advisory is in effect for the entire
Cold advection and cyclonic flow will keep plenty of clouds
around on Thursday. There will also be some scattered low-top
showers with steep low-level lapse rates.
Overnight lows will range from the upper 40s to lower 50s,
generally a few degrees above normal. Highs on Thursday will
below normal behind the low with the cold advection, ranging
from the mid 50s to around 60.|
Short term Thursday night
Low pressure over northern new england will gradually weaken as
it lifts up into the canadian maritimes. As a result, winds
will gradually subside through the night, but still gusting 20
to 30 mph. Lows will generally be in the 40s, fairly homogeneous
with the airmass remaining well mixed.
Long term Friday through Wednesday
Low pressure continues to move away from the area, moving into the
canadian maritimes, while high pressure builds into the area on
Friday. There will continue be a strong pressure gradient between
the low and incoming high, so conditions will still be rather
breezy, with winds diminishing in the afternoon. Gusts of 25 to 30
mph are possible.
A northwest flow will keep temperatures near or just below normal
across the area on Friday, with highs in the upper 50s to around 60.
Similar temperatures are expected on Saturday.
Mainly dry conditions expected with high pressure moving overhead
and offshore over the weekend. The one concern is that the GFS is
developing an area of low pressure off the coast of the carolinas,
then heading northeast. Although this is an outlier, there is enough
uncertainty to have low end slight chance pops across most of the
tri-state. The forecast area will be on the northern fringe of this
possible storm, also warranting slight chance pops.
This coastal low is reflected in the ECMWF and canadian, however, it
makes little headway over the southeast u.S., but the retreating
high noses back into the area, keeping the area mostly dry through
Sunday night. The ECMWF does bring in some precipitation on the
northern fringe Sunday night, so although dry right now, slight
chance pops are possible Sunday night.
A more potent system may impact the area Monday into Tuesday, with a
period of moderate to briefly heavy rain. It is too far out to pin
down any details at this time.
Aviation 20z Wednesday through Monday
***high impact rain and wind event into Thursday***
an intensifying low pressure system will approach the west this
evening and move across the region tonight.
Clouds will continue to lower and thicken with MVFR CIGS at many of
the terminals. Rain has begun to overspread the region, mainly in
the form of showers west of nyc. Steadier rain will move in through
22-23z. The rain will be heavy at times, before tapering off around
04-06z but MVFR CIGS around 3000 ft may remain through the remainder
of the TAF period. There is a low chance of thunder this evening,
however chances are too low to include in the tafs at this time.
Se winds continue to increase this evening, with gusts at or above
30 kt likely by late evening tonight. Direction will vary as the low
tracks over and through the area. Winds become westerly behind the
system late tonight, and remain so through Thursday. Gusts 35-40 kt
will be possible on Thursday.

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.
