Synopsis
Low pressure passes to our southeast overnight, followed by
high pressure for Sunday. The high then slides offshore through
Monday. A warm front approaches from the southwest Monday night,
then lifts to the north Tuesday, followed by a slow moving cold
front crossing the area during the middle week. High pressure
may briefly build in to close the upcoming work week, before
another frontal system approaches for the weekend.

Near term until 6 am this morning
Rain snow line, based on dual-pol, has made progress to south
coast of LI nyc as of 03z, but is also eroding as it does so.

Meanwhile, back edge of steady accumulating snow is beginning
to make progress eastward into orange county.

Widespread reports of 5 to 8" across interior NE nj and lower
hud as of 10 pm. Generally 2 to 5" across nyc metro, 3 to 6"
across SW ct, and 1 to 3 across LI SE ct as of 10 pm.

Based on low pressure deepening to the SE of buoy 44066,
expectation is that rain snow line does not much make much
progress north of belt pkwy southern state across western li,
and stalls btwn sunrise hwy and lie across suffolk county over
the next couple of hours. This is fairly consistent with
previous forecast and nam. Expectation of a significant snow
gradient across li, from around an inch across the south shore
of the south fork of LI to 4 to 7 inches for the hills of nw
suffolk and nassau county.

Heaviest total snow, 6 to 10", expected across NE nj lower hud
and southern ct based on upstream obs and most persistent
moderate to heavy snow banding continuing over the next few
hours with surface temps in the upper 20 to lower 30s.

Wsw's remain as is. Snow should begin to taper from W to e
between 6z and 10z.

Short term 6 am this morning through 6 pm Monday
Ridging at the surface and aloft occurs on Sunday, with high
pressure shifting offshore on Sunday night. Dry weather through the
period with a mostly clear sky. Sided with the colder side of
guidance for temperatures due to a fresh snow pack.

Long term Monday night through Saturday
Anomalously strong bermuda east coast ridging develops early this
week and continues into midweek, in response to deep western
troughing. The western trough will gradually shear NE in piecemeal
fashion for the late week weekend, resulting in a transition to a
bit more suppressed but active confluent SW upper flow.

At the surface, high pressure slides off the coast on Monday, and
then becomes established under the upper ridge by midweek. Meanwhile
a slow moving frontal system will cross through the mississippi
river valley the first half of the week. Its warm front likely
approaches Monday night with rain and then gets pushed north of the
region on Tuesday. An unseasonably warm SW flow is likely Tue wed
under deep layered ridging, with highs around 70 possible for nyc nj
metro and areas n&w on Tue and lower to mid 70s on wed. Meanwhile
south coastal areas may struggle to get out out of the 50s due to
the cold water temp. Coastal advection stratus fog and nocturnal
radiation fog is possible during this time as well.

Models in general agreement with the eastern ridging breaking down
enough, to allow a stream of shortwave energy to approach and push
an approaching cold front towards and through the region Wed night.

This likely brings another round of rain to the region Wed night
through Thursday.

Potential for brief ridging Friday, before next shortwave and
associated frontal system affect the region on Saturday with another
round of rain.

Temps during the period expected to average well above average, with
high temps potentially 25-30 degrees above normal Tue and Wed for
nyc nj metro and areas n&w..

Aviation 06z Sunday through Thursday
Deepening low pressure tracks southeast of montauk point
overnight, and then to the northeast and east Sunday morning as
high pressure builds to the west. The high builds over the
terminals Sunday, then moves off the northeast coast Sunday
night.

Light snow, with rain and or snow across the twin forks of long
island will be ending overnight into early Sunday morning, 08z
at kswf to 12z at kgon. Ifr to lifr will quickly improve toVFR
as the precipitation ends.

Northerly winds less than 10 kt back to the northwest as the
low tracks southeast of montauk point overnight into early
Sunday morning. NW winds will increase to 10-15 kt, with gusts
18 to 25 kt during the day Sunday. Gusts and winds diminish
during the afternoon, 18z to 19z, and then become light and
variable by 00z Monday.

Outlook for 06z Monday through Thursday
Late Sunday night-Monday Vfr. Becoming MVFR to ifr in rain
and possibly fog Monday afternoon.

Tuesday MVFR or ifr possible in the morning and again at night,
otherwiseVFR with SW wind g20kt possible.

Wednesday Vfr. Chance of showers with MVFR.

Thursday MVFR in rain.

Marine
Sca for the ocean waters for Sunday morning into early
afternoon with increasing winds and seas. There could be some
gusts to 25 kt Sunday morning over the eastern sound and eastern
bays, but coverage didn't warrant an advisory. Sub-sca conds
otherwise tonight and from late Sunday afternoon through Sunday
night.

Generally sub-advsy winds expected Mon through wed, but a persistent
15 to 20 kt SW flow may have sea building to SCA levels Tue wed.

Seas should subside Wed night into Thu as a weak cold front passes
through and winds become offshore.

Hydrology
Around 1 2 to 3 4 an inch of liquid equivalent is expected Saturday
night with locally higher amounts. With most, if not all of this
falling in the form of snow, no hydrologic impacts are expected.

No significant hydrologic impacts are expected from Sunday through
the end of next week.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
