Synopsis
Weak high pressure builds farther offshore tonight as a cold
front approaches from the great lakes. The front moves through
the area Tuesday evening. High pressure will then briefly follow
for the middle of the week. Another frontal system approaches
for the end of the week.

Near term until 6 am Tuesday morning
A weak surface trough was across the region from the hudson
valley into eastern pennsylvania and into north central
maryland. This was the focus of a few light showers, along with
a shortwave rotating through an upper trough. Put
probabilities, slight chance, into the forecast for areas across
the far western zones initially and then slowly east through
the overnight. The hrrr was also supporting the chance of
showers overnight, just a couple of hours too quick. Lower
levels are dry and any precipitation reaching the ground is
expected to be light.

Anomalously strong upper trough across the great lakes and ohio
valley states pivots eastward the next couple of days with
gradual height falls and increasing daytime instability.

Short term 6 am Tuesday morning through Tuesday night
Airmass gradually destabilizes on Tuesday with height falls and
approaching cold front over the great lakes. However, dry low-
levels and lack of strong surface trigger will be limiting
factors for the development of showers thunderstorms. The best
chance will be across the interior during the afternoon hours.

Wind shear is also weak, limiting any organization.

Cold front works across the area in Tuesday evening with high
pressure to follow.

Daytime highs will once again be near or just below seasonable
levels.

There is a moderate risk for the development of rip currents
Tuesday.

Long term Wednesday through Monday
High pressure will be in control Wednesday through Thursday night,
bringing dry conditions and near normal temperatures across the
area. As high pressure moves offshore, warmer temperatures and
increasing chances of showers and thunderstorms will develop Friday
through Sunday. High pressure builds back on Monday, bringing more
seasonable temperatures and dry conditions across the area.

Aviation 03z Tuesday through Saturday
A weak trough of low pressure over the area will move east late
tonight... Followed by another one on Tuesday.

Vfr through the TAF period.

An area of showers over SE pa may impact kswf between 05z and
06z. Latest hi res guidance weakens this activity as it tracks
ne next few hours... So will watch and amend as needed. Also a
few showers have popped up in northern md, but is not as much
widespread as some of the earlier guidance was indicating. Thus,
have decided to hold off on adding showers to other terminals
for now.

S-sw winds 5-10kt will become light and vrb outside of nyc
terminals overnight. Winds will increase 10-15kt Tue aftn with
gusts in the upper teens to lower 20s... Becoming w-nw around 00z
as the trough pushes through.

Could be some isold showers tstms Tue aftn associated with upper
disturbance and sfc trough moving through.

Outlook for 00z Wednesday through Saturday
Tuesday night-Wednesday Vfr.

Thursday Vfr. Chance of a late day shower thunderstorm.

Friday and Saturday Sub-vfr in showers and thunderstorms.

Marine
Winds and seas forecast on track.

With an overall weak pressure gradient remaining across the
region, winds and seas are expected to remain below small craft
advisory criteria (25kt winds, 5 ft seas) through Tuesday.

Below small craft advisory conditions expected Wednesday as high
pressure moves south across the area waters. Winds and seas
increase, and small craft advisory conditions are possible later
Thursday and into Saturday.

Hydrology
No hydrologic impacts expected through the beginning of next
week.

Tides coastal flooding
Astronomical tides are still running high with a low chance of
any minor coastal flooding across the south shore back bays of
nassau county with this evening high tide cycle, approximately
between 10pm and 12am. The water levels would only be expected
to touch the minor benchmarks few just a couple of gages so no
statement has been issued.

Equipment
Observations from kfrg (farmingdale, ny) are not available.

Observations from khpn (white plains ny) and khvn (new haven ct)
are being disseminated through backup methods. All is due to
an faa communication line outage. Return to service time is
unknown.

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.
