Synopsis
Multiple weak waves of low pressure pass to the south through
Monday, as high pressure gradually builds down from southeastern
canada. This high retreats to the northeast Monday night. A
series of weak fronts or troughs of low pressure cross the area
Tuesday through Thursday. Weak high pressure then builds in
through Friday, as a front stalls to the south of long island.

Near term until 6 pm this evening
A dissipated convective complex and associated shortwave will
pass just to the SW S of the area this afternoon (consistent
with trajectory of mean 850-500 hpa flow). An isolated shower
possible across nyc metro and point N & W due to combined
shortwave forcing and weak instability. Additionally this
should result in sct-bkn CU this afternoon.

Highs today will be near normal... Generally upper 60s lower 70s
south coasts with afternoon sea breeze knocking temps back into
the 60s. Across nyc nj metro and interior lower to mid 70s.

There is a moderate risk of rip currents at the ocean beaches
today due to residual 3 ft southerly swells.

Short term 6 pm this evening through 6 pm Sunday
Northern stream 850-500 hpa ridging builds in tonight, as
onshore flow sets up below 900 hpa. Could end up seeing some
patchy drizzle late tonight into early Sunday morning as a
result. Lows tonight should be a few degrees above normal.

The aforementioned ridge axis transits over the area Sunday,
with moisture trapped under the subsidence inversion making for
a mostly cloudy day. Given expected cloud cover and onshore
flow, did cut back on highs to around 5-10 degrees below normal.

This was based on blending NAM ecwmf 2-meter temperatures in
with met ecs guidance and a mix down from 975-925 hpa per bufkit
soundings.

Long term Sunday night through Friday
The northern stream ridge slides offshore Sunday night, allowing
for light rain to overspread most of the area with some modest
isentropic ascent (could remain dry over far eastern portions).

A northern stream shortwave rotates across the area around the
base of a closed low over ontario northern great lakes Monday.

Even with onshore flow, showalter indices are progged down to -2
to -4 by afternoon in response to fairly steep mid-upper level
lapse rates, have opted for showers, with a chance of
thunderstorms by afternoon. Given showalter indices cannot rule
out some locally strong storms and cannot 100% rule out a
severe cell or two. The main threat would be large hail - with
wet bulb zero heights progged at 8-9 thousand feet late Monday
afternoon early Monday evening. The marine inversion likely will
prevent any gusts to severe levels.

The showers with embedded thunderstorms should come to an end
from SW to NE Monday night as the shortwave trough exits to the
ne.

The closed upper low and longwave trough will be slow to move
east through the middle to late part of next week as a series
of shortwaves rotate through the trough, while at the surface
weak lows, or troughs move through the area. There remains a lot
of uncertainty with the timing and placement of the systems
through the upcoming week. As a result, there could be a
prolonged period of unsettled weather. Will carry slight chance
to low chance probabilities through Thursday, highest over
northern zones, closest to the closed low any shortwaves
rotating around it. For now have gone with a dry forecast
Thursday night and Friday as the main axis of the opening
closed low is progged to lift to the northeast.

Aviation 15z Saturday through Wednesday
Weak high pressure remains over the terminals today.

Vfr. Light NW to W winds give way to sea breezes with winds
shifting S to SE at 10 kt or less.

Outlook for 12z Sunday through Wednesday
Sunday MVFR and any local ifr CIGS gradually improving toVFR
by afternoon.

Sunday night Vfr, but with chance of light rain late.

Monday MVFR conds likely and ifr conds possible. Showers
likely and chance of tstms.

Monday night Conds improving toVFR by late evening.

Tuesday-Wednesday MainlyVFR. Chance of showers tstms mainly
nw of the nyc metro terminals.

Marine
Quiet through Sunday night as ocean swells subside and winds
remain light. SE winds increasing to 15-20 kt on Mon could
lead to ocean seas reaching 5 ft again Mon afternoon evening.

Otherwise, outside of any tstms on Monday, winds seas on the
waters should remain tranquil.

Hydrology
No significant widespread hydrologic impacts are expected
through at least the middle of next week.

Tides coastal flooding
The combination of high astronomical tides and southerly swell
will keep water levels within striking distance of minor coastal
flood benchmarks for several high tide cycles into early next
week. A coastal flood advisory is in effect for the high tide
cycle tonight for the south shore bays of brooklyn queens nassau,
also for the shores of westchester fairfield along western long
island sound.

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.
