Synopsis
Low pressure will move southeast of long island tonight followed
by high pressure Wednesday through the day Thursday. Low
pressure approaching from the central states will impact the
region Thursday night into Saturday. High pressure will build in
on Sunday and Monday. Another disturbance may affect the area
next Tuesday.

Near term /until 6 am Wednesday morning/
The combination of both a weak upper level short wave and low
pressure just southeast of atlantic city is producing widespread
rain and mainly light fog across the entire local area.

Pops were increased to reflect near term trends until 03z.

Radar estimated hourly rainfall rates up to .3 caused
significant within bank rises across streams in western union
county with ewr measuring .34 inches in 1 hour.

Otherwise, the latest animated satellite imagery shows the back
edge of the enhanced clouds across eastern pa, where light rain
is still occurring.

Still holding with rain tapering off aft 04z w-e, ending by 10z
extreme east sections.

Used a guidance blend for lows tonight, with lower 40s invof
nyc, upper 30s most elsewhere, and isolated mid 30s well inland.

Short term /6 am Wednesday morning through Wednesday night/
Dry weather with a northwesterly breeze. Despite a cooler deep
layer air mass in place, sfc temperatures will actually be
warmer than Tuesday because of deep mixing. Mostly sunny skies
are progged, with some fair weather CU especially NW of nyc.

Took the high side of guidance for temps, with mid/upper 50s
most places, and upper 40s/lower 50s in the higher elevations.

Guidance may be underdone by quite a bit on winds for wed
evening as low pressure off to the east intensifies. Model
soundings out east show winds 35-40 kt atop the mixed layer.

Trended forecast higher, with gusts up to 25 lasting until about
midnight.

Lows should be in the mid 30s INVOF nyc, lower 30s along the
coastlines and in the nyc suburbs, and 25-30 elsewhere.

Long term /Thursday through Tuesday/
High pressure builds in for Thursday, then moves offshore Thursday
night. High temperatures on Thursday will be in the low to mid 50s.

Clouds will increase Thursday night as warm advection begins to move
in ahead of an approaching low pressure system. Expect periods of
rain starting Thursday night into Saturday. Some lingering cold air
across the northern portions of our CWA Thursday night may result in
a mix of snow and rain before warm advection increases. So have kept
the mix of snow and rain inland. High temperatures on Friday and
Saturday will be in the mid 40s to around 50.

Canadian high pressure builds in for late Saturday night into
Monday. Another disturbance may approach for Tuesday. Temperatures
during this period will be in the mid to upper 50s which is near
normal for this time of year.

Aviation /00z Wednesday through Sunday/
Low pressure along a frontal boundary moves east of the region
overnight, with winds backing from NE to NW at near 10 kt or
less. High pressure builds in thereafter through Wednesday.

Expecting mainly ifr and locally below conditions tonight. The
rain this evening will taper off late but the low stratus
will remain. As winds become more NW early Wednesday, conditions
will eventually improve toVFR.VFR for Wednesday overall but
with NW gusts near 20 kt during the day.

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.
