Synopsis
High pressure to our east gives way to an approaching warm front
tonight which likely moves through by Sunday morning. A trailing
cold front passes through Sunday night. High pressure will briefly
follow on Monday. Another warm front will then move through on
Tuesday, with a cold front following for Thursday into Thursday
night.

Near term until 6 pm this evening
The forecast is on track with minor adjustments made to some
hourly forecast elements.

Upper ridge axis becomes centered over us today with surface high
pressure not too far offshore. More clouds overall in the afternoon,
and ridging should be strong enough to hold off on any showers
trying to move in from the west through the day. Highs around 70 at
the coast with an onshore flow, and low to mid 70s elsewhere.

There is a low risk for the development of rip currents today.Rents
today.

Short term 6 pm this evening through Sunday night
A warm front approaches tonight. Isentropic and shortwave lift
combine with deepening moisture for a chance of showers with
generally better overall chances after midnight. The best overall
combination of moisture and lift will be across ct and eastern li,
where likely pops have been maintained. Will also keep isolated
thunderstorms in the forecast as elevated CAPE shifts in.

The warm front likely passes through most, if not all, of the
forecast area tonight. It otherwise should clear the area during
Sunday morning. This leads to a warmer and more humid day with high
temperatures mostly 10-15 degree above normal. Enough dry air aloft
will help mix out surface dewpoints a little out ahead of any
potential moisture pooling along an approaching cold front. Heat
index values will therefore be near ambient temperatures.

The cold front approaches from the NW and moves through during the
late afternoon evening hours. Capping and a relatively drier profile
look to keep us dry in the morning. Increasing lift, moisture and
cape along with steeper lapse rates then bring isolated scattered
showers and thunderstorms in the afternoon and evening. Some storms
could have strong gusts given modeled shear values and a somewhat
dry sub-cloud layer inverted-v profile. Dry weather then follows for
the overnight hours behind the front.

There is a low risk of rip current development on Sunday.

Long term Monday through Friday
Weak high pressure builds in for Monday with a continuation of dry
weather and less humid than Sunday. Highs still above normal, but
not a warm as Sunday. High pressure then moves offshore Tuesday,
allowing a return to warm advection with a front slowly moving
northeastward through the region, which may spark a few
thunderstorms.

We then stay solidly in the warm sector for Wednesday and Thursday,
with temperatures well above climatological normals and an
increasing chance for diurnal thunderstorms. Once again although
forcing for ascent is weak and confined to a subtle short wave and
surface trough for Wednesday, steep low and mid level lapse rates
may contribute to a few stronger cells. Chances of strong
thunderstorms then increase into late Thursday with the approach of
a cold front, especially with the increasing wind field as the upper
trough nears. The front then passes through overnight, marking a
return to more seasonable conditions.

Aviation 11z Saturday through Wednesday
High pressure moves offshore today. A warm front approaches
from the west tonight.

Vfr today. Light S SE winds are expected initially. Winds then
become southerly 10-15 kt, strongest at the coast through the
day. A few gusts to 15-20 kt are possible in the afternoon,
especially near the coast.

Showers and isolated thunderstorms are possible tonight, but
coverage will be scattered. Timing would be late evening into
the overnight hours. MVFR, local ifr conditions, are expected
mainly after midnight.

Outlook for 12z Sunday through Wednesday
Sunday MostlyVFR. Chance of MVFR or ifr early, and again in
a late day shower tstm.

Monday Vfr.

Tuesday-Wednesday Chance of MVFR or lower with
showers thunderstorms, mainly in the afternoon and evening each
day.

Marine
Sub-sca conditions today with a southerly flow increasing in the
afternoon. Winds continue to increase tonight with near-advisory
conditions, but should prevail below it. Winds then weaken a little
on Sunday with the continuation of sub-sca conds, which will last
through Wednesday, although thunderstorms will be capable of
producing locally hazardous conditions at times.

Hydrology
Rain amounts with showers tonight will most likely range up to
around a quarter of an inch. No hydrologic impacts are anticipated
with this, and are not anticipated into next week as well.

Nyc NOAA weather radio station kwo35 (162.55 mhz) remains off

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.
