Synopsis
High pressure remains over the region through Tuesday with only
a couple of weak troughs of low pressure moving in. A cold front
approaches Wednesday and moves through Wednesday night. High
pressure then builds in through next weekend.

Near term until 6 am Monday morning
Shortwave lift pushes through this evening with the strongest lift
over the northernmost zones. At the same time, capes diminish, but
still unstable enough for a chance of strong thunderstorms. Severe
storms not out of the question given marginally strong enough winds
aloft with a weakly veering shear profile. This would be for mainly
the NW half of the forecast area. Still a chance of additional
showers and tstms late at night, but probably with less coverage as
we continue to stabilize. Patchy fog is anticipated as well.

Muggy conditions into this evening expected. A heat advisory has
been issued for portions of the tri-state area. See the short term
section below for more details.

There is a low risk for the development of rip currents at atlantic
ocean beaches into this evening.

Short term 6 am Monday morning through Tuesday
The overall pattern doesn't change all that much for Monday
through Tuesday night with a somewhat flat flow aloft
interrupted by late-day early evening shortwaves. Showers tstms
are possible both days, and again, best chances highest
coverage in the afternoons and evenings as lift and instability
are maximized. Marginal speed and directional shear would appear
to bring at least a low chance of strong to severe storms both
days.

Regarding temperatures and heat indices, Monday's 850mb temps are
forecast to be 18-19c and slightly cooler on Tuesday. Full mix down
potential both days will be limited by somewhat high dewpoints at the
top of the mixed layer, and for areas nearby the water, a southerly
flow. Uncertainty of cloud cover also complicates the high
temperature forecast, but thinking it should be at least partly
sunny rather than mostly cloudy both days. Surface dewpoints won't
have a great opportunity to mix out both days given the wind
direction and dewpoints aloft. So with highs generally in the upper
80s to lower 90s and dewpoints in the lower 70s, heat index values
are expected to reach at least 95 for most of the forecast area on
Monday, but with less overall coverage on Tuesday. Will go with
advisories where the criteria is expected to be met for the Sunday-
Monday period, and let subsequent shifts assess the need to add
Tuesday as appropriate.

There is a moderate risk of rip current development at atlantic
beaches on Monday.

Long term Tuesday night through Sunday
Hot, humid and unsettled weather continues through wed, possibly
into Thu depending on the progression of a closed low traversing
eastern canada and its associated cold front. 12z nwp model
suite is in good agreement with the overall upper pattern
across north america during the long term period, although there
are some slight timing differences and amplitude differences,
especially with the eastern canadian low.

Heights begin to fall Tue night as the closed low over hudson
bay drops into southern quebec and ontario. There will be
shortwaves moving around the trough that extends into the lakes
and northeast, but the details on the timing of these are still
in question. Thus, have chc pops Tue night into Wed morning.

Better chances for showers tstms will come Wed aftn night with
the development of a pre frontal trough west of nyc and an
approaching cold front. Too early to say whether there will be
severe weather, but it is a possibility if things align right.

Front may only be about halfway through the forecast area by thu
morning so could have additional convective activity across
eastern locations on Thu before it clears the area.

A cooler and more comfortable airmass filters in behind the
front for Fri into the weekend. Upper troughing will linger into
sat with another shortwave progged to move through, although
there may not be enough available moisture for any pcpn. Have
kept forecast dry for now. Temps are expected to be near to
slightly below normal levels during this time.

Aviation 20z Sunday through Friday
Low pressure passes to the south and east through tonight.

Vfr late this afternoon into the evening, outside of an isolated
shower or thunderstorm which could briefly cause a reduction in
visibilities and ceilings. For tonight, expect stratus fog once
again, mainly east of the nyc terminals, and possible patchy fog at
hpn and swf. Once the stratus and fog burn off,VFR once again
Monday morning.

Winds will be southerly around 10 kt. Speeds diminish after
sunset.

Outlook for 18z Monday through Friday
Monday afternoon-Monday night MainlyVFR, but MVFR is
possible in any showers or thunderstorms.

Tuesday-Thursday MainlyVFR, but sub-vfr possible in showers or
thunderstorms.

Thursday night-Friday Vfr.

Marine
A light pressure gradient will maintain relatively tranquil
conditions on all waters through Tuesday night.

Sub advsy conds are expected to prevail through the period,
outside of tstms. Wind gusts and seas on the ocean could
approach 25 kt Wed night and 5 ft Wed night into thu, although
feel that guidance was overdoing the seas on SW flow so have
knocked them down a foot for now.

Hydrology
No hydrologic impacts are expected at this time through the forecast
period.

Equipment
Nyc NOAA weather radio station kwo35 (162.55 mhz) remains off
the air.

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.
