Synopsis
A weak frontal boundary stalls south of the area today while
high pressure builds to the north. By tonight, a wave of low
pressure will move along the frontal boundary south of the
region. Weak high pressure builds in on Wednesday, followed by low
pressure Thursday into Friday. High pressure returns for the
beginning half of the upcoming holiday weekend, but low pressure
may again bring some unsettled weather during the latter half.

Near term /until 6 pm this evening/
The weak frontal boundary and associated rain has moved well
east of the area. Northwest flow behind the boundary will advect
in drier air that will gradually erode any remaining fog by
early morning. Mainly mid and high-level cloud cover is
expected for the remainder of the day in broad southwest flow
ahead of a larger scale upper low and a series of short waves
that will bring episodic rain to the region this week.

High temperatures will be closer to climatological normals,
generally in the 70s.

Short term /6 pm this evening through 6 pm Wednesday/
Mid and high-level clouds will continue to increase ahead of a
short-wave that will contribute to a deepening area of low
pressure of the coast. With the system passing to the south, the
best chance of any rainfall will be closer to the coast,
particularly across eastern long island and connecticut
overnight. Cloud cover and somewhat stronger northeast flow will
keep low temperatures close to normal. By afternoon, the low
departs giving way to south flow and near normal temperatures
that will be slightly cooler near the coast in onshore flow.

Long term /Wednesday night through Monday/
An unsettled weather pattern continues through the long term period.

Another round of rainfall arrives late Wednesday night, with
rainfall being most likely Thursday into Thursday night. Some
elevated instability should be present, so will keep isolated
thunder for Thursday and Thursday night. There could also be some
fog for late Wednesday night into Thursday morning with a warm
front not too far off to the south. The low exits to the NE on
Friday, but the threat of showers will remain in the forecast.

Temperatures will be slightly below normal on Thursday, then
return to more seasonable levels on Friday.

Weak high pressure then returns Friday night and Saturday. Will go
with a dry forecast and slightly above normal temperatures for now.

Another low pressure system is then expected for Sunday and Monday,
brining yet another round of unsettled weather to the region.

Aviation /07z Tuesday through Saturday/
Weak high pressure will build across the area this morning and
then offshore this afternoon.

Improving toVFR this morning with mid and high level clouds
increasing through the day. There is a low chance of light rain
at late this afternoon.Eavening, mainly at the coastal
terminals.

N-ne at 5-10kt this morning. An afternoon seabreeze is probable
at all but kswf/khpn.

Outlook for 06z Wednesday through Saturday
Tuesday night-Wednesday evening Vfr.

Wednesday night-Friday night MVFR or lower possible. Slight
chance of thunderstorms Thursday. E winds g20kt with llws
possible.

Saturday Vfr.

Marine
Winds and seas are expected to remain below small craft levels
through tonight. Overnight, an initially weak pressure gradient
will tighten as an area of low pressure moves up the coast. As
such, winds will increase allowing seas to gradually build to
sca levels by tomorrow afternoon/evening. Seas may remain
elevated on the ocean through Wednesday night. Low pressure will
approach the waters Thursday night through Friday night,
bringing the next chance if advisory level conditions. Seas will
increase again to 5-6 ft late Thursday night and continue
through Friday. Seas finally diminish Friday night to below 5
ft. Wind gust through this time will primarily remain between
20-25 kt. Conditions fall back below SCA levels for the weekend.

Hydrology
No hydrologic impacts are anticipated tonight through the end of
the week.

Tides/coastal flooding
Minor coastal flooding thresholds may be reached with Wednesday
night's high tide cycle for southern sections of ny harbor, the
south shore back bays of western li/queens/brooklyn, and western
long island. A better chance of minor flooding arrives for Thursday
night, with northern ny harbor and parts of central LI sound also
included. Chances then lower on Friday night as winds likely shift
offshore.

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.
