Synopsis
High pressure will build to the south through Saturday, while
low pressure passes well to the north on Saturday. A back door
cold front will pass through Sunday night, then return north as
a warm front on Monday ahead of a strong frontal system for
Monday night into Tuesday. High pressure will return for mid
week.

Near term until 6 pm this evening
High level clouds a bit more opaque than earlier anticipated due
jet energy rounding a departing upper trough across new england.

This may impact high temperatures slightly on the lower side of
the guidance.

Skies should become partly sunny this afternoon. Temps will be
5-10 degrees warmer than those of yesterday, with highs mostly
in the upper 30s and lower 40s.

Short term 6 pm this evening through 6 pm Saturday
Zonal flow will prevail aloft between a flat trough passing to
the north and ridging along the SE coast. After one more cold
night inland with lows in the teens 20s, and lower 30s for nyc
metro and most of long island, downslope flow WAA will result in
a mild day, with high temps in the upper 40s and lower 50s. It
will however be brisk, as a tightening pressure gradient between
low pressure passing E across quebec and high pressure along
the SE coast generates W to wsw winds gusting up to 35 mph in
nyc and across long island, and 25-30 mph most elsewhere to the
north west.

Long term Saturday night through Thursday
Zonal upper flow through the weekend, with confluence of pacific
and polar jet to the north of the region, and southern stream
energy tracking through the deep south. Continued return flow
around southern high pressure Sat night into Sunday will allow
for dry and unseasonably mild conditions under a pacific air
mass, with high temps in the lower and mid 40s on Sunday.

A vigorous polar shortwave moving through southeastern canada
Sunday night will likely have a back door cold front pushing
through the region, bringing in a more seasonable canadian
maritime air mass for Monday.

Meanwhile, models in good agreement with the relatively tranquil
pattern being interrupted early next week by the pacific
energy coming into the western states today. This pacific
shortwave will amplify through the SW states, and eventually
phase with subtropical jet energy. The resultant deep closed
low is then expected to gradually track NE across the central
plains and mid mississippi valley Sunday into mon, before
approaching the northeast by Tuesday as it begins phasing with
northern stream energy. There are still some timing amplitude
differences with this energy, which is manifesting in
timing track differences of a resultant frontal system as it
tracks toward the region Monday night into Tuesday. This model
spread should decrease over the next 24 hrs as pacific energy
comes onshore, but subtle model differences may continue
through Sunday until the subtropical and pacific energy phase.

Regardless, there has a been consistent model-to-model and run-
to-run signal for a quick moving moderate to heavy rain event
for Monday night into Tuesday, in response to strong deep
layer lift (region under of nose of 65-70 kt LLJ and left front
quad of a 100+ kt jet streak in difluent upper flow) of a
subtropical moisture plume with pw +2 to + 3 standard deviations
above normal over the region, focused ahead of the cold front
and a surface wave. Before that, still appears there is
potential for a light wintry mix N NW of nyc metro Monday
morning as a warm front moves north with increasing theta-e
advection.

The frontal system pushes through on Tuesday, with breezy
conditions and CAA in its wake, returning dry and more
seasonable temps for Wed thu.

Aviation 16z Friday through Tuesday
High pressure remains centered to the southwest of the region
through tonight.

Vfr through the TAF period.

Winds may briefly strengthen to 10-14 kt this afternoon with an
occasional gust to 18 kt. Otherwise, W flow gradually backs to SW by
this evening.

Ny metro enhanced aviation weather support...

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.
