Synopsis
High pressure gradually retreats to the northeast as a series of
weak lows track to the south of long island through Tuesday. A
weak cold front approaches from the west Tuesday night, then
crosses the area Wednesday. High pressure then builds in to the
south and southwest through Thursday night. A cold front
approaches on Friday then slowly crosses the area Friday night
and Saturday.

Near term until 6 pm this evening
A deep layered northern stream ridge builds over the area today.

However, with abundant low level moisture being trapped under
the associated subsidence inversion, should see more clouds than
sun over the area. This coupled with onshore flow, should
result in temperatures being towards the cooler end of guidance.

This is consistent with a blend of ecs met guidance, NAM and
ecmwf 2-meter temperatures and a mix down from 975-925 hpa per
bufkit soundings. Highs should be around 5-10 degrees below
normal.

Short term 6 pm this evening through 6 pm Monday
The northern stream ridging slides offshore tonight, delaying
the onset of light rain (in response to increasing isentropic
lift) until mainly after midnight.

A northern stream shortwave pushes through the area Monday.

Along with it are some fairly steep mid level lapse rates,
reflected with showalters progged down to around -2 and possibly
as low as -4. This should be sufficient to turn the character of
the precipitation to more convective driven, so have gone with
showers with embedded thunderstorms. Noting showalters of -2 to
-4, cannot rule out some locally strong storms. With wetbulb
zero heights of 8000-9000 ft, small hail is a possibility.

There is also a very small chance of an isolated sever storm,
with the main threat hail of 1+" in diameter.

Precipitation should taper off from SW to NE this
afternoon early this evening as the shortwave trough lifts to
the ne.

Lows tonight should be near normal and highs Monday around 10
degrees below normal.

Long term Monday night through Saturday
A closed low will slowly track from SW ontario N great lakes
Monday night to pres over southern ontario will slowly track to
near the quebec ontario boarder by Thursday morning. There will
be shortwaves rotating around this rather broad closed low, that
could trigger some isolated to scattered showers from time to
time through Wednesday night, with the best chance over
northern zones.

The models then differ on how fast far the closed low works to
the east Thursday-Saturday, in part because they differ on how
it is re-enforced from the west. As a result, the forecast from
Thursday on is of at best low-moderate confidence in the
details.

For now it appears that Thursday and Thursday night should be
dry, with the region potentially in between main spokes of the
closed low. The next spoke then influences our weather Friday
or Saturday, so have just slight chance pops for now until the
timing of the system can be better refined.

Temperatures start out near normal Monday night and Tuesday,
should be above normal Wednesday, then near normal again
Thursday-Saturday.

Aviation 07z Sunday through Thursday
High pressure will remain fairly stationary to the east through
tonight. A frontal system will begin to approach late Sunday
night.

While bkn-ovc higher-based clouds cover most of the area,
satellite shows no sign of low cloud development south of long
island or east of the jersey shore, so for the most part have
omitted mention of lower CIGS through the morning, except at
kbdr kisp, where even the most optimistic of forecast guidance
still insists on MVFR CIGS anywhere from 09z-15z. Confidence
here is medium at best, and will still have to closely monitor
for any low cloud development. Confidence should be higher
with the 09z amd's.

Light se-s flow should become SE 8-12 kt by afternoon, then
diminish again tonight.

Some light rain with MVFR conds could reach the nyc metro
terminals just before 06z mon.

Outlook for 06z Monday through Thursday
Late Sunday night MVFR conds developing from west to east,
with light rain especially from nyc metro on west.

Monday Showers likely and chance of tstms. Ifr conds
possible.

Monday night Still a chance of showers tstms early from
kbdr kisp east with MVFR or lower conds, otherwiseVFR.

Tuesday Chance of showers and possibly a TSTM with brief with
MVFR or lower conds in the afternoon evening.

Wednesday MainlyVFR. Chance of showers tstms mainly NW of
the nyc metro terminals.

Thursday Vfr.

Marine
In the near term, will be watching the ocean waters mainly west of
moriches inlet for development of any fog before daybreak and
lasting into the morning. So far nothing has developed, but given
the moist onshore low level flow, cannot rule out the possibility.

An SCA may be needed for the ocean waters late tonight into the
daytime hours on Monday. Increasing SE flow looks to peak at
20g25kt Monday morning, with MAX seas per wavewatch and buoy
wind wave climatology 5, maybe 6 ft, with the higher conditions
and longer duration more likely to be out east during the
daytime hours on Monday.

Otherwise, sub-small craft advisory conditions are expected
through Thu night.

Hydrology
Dry today.

Total rainfall amounts tonight and Monday could range from
around 1 3 to 1 2 of an inch, with locally higher amounts
possible in areas experiencing strong convection Monday. In
areas that do experience strong convection, there is the
potential for at least localized ponding of water on roadways.

No significant widespread hydrologic impacts are then expected
at this time from Monday night through at least Thursday night.

Tides coastal flooding
Widespread minor coastal flooding is expected for the high tide
cycle tonight along the south shore bays of brooklyn, queens,
and nassau, also for the shores of westchester fairfield along
western long island sound. A coastal flood advisory continues
for these areas. Brief localized minor flooding possible
elsewhere along western long island sound and lower ny harbor.

While astronomical tides are lower for the Sunday night high
tide, surge will likely increase a bit with strengthening se
flow. The net result looks to be additional widespread minor
coastal flooding for the south shore bays of western long
island, with localized brief minor flooding possible for the
rest of the areas that have been affected over the last
several days.

Okx watches warnings advisories
Ct... None.

Ny... Coastal flood advisory from 10 pm this evening to 3 am edt
Monday for nyz179.

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.
