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
Afternoon seabreeze has made good northward progress along the
connecticut and long island coasts, and has pushed well inland.

Due to mid level capping and dry low-levels, convection is not
expected the remainder of this afternoon early evening, outside
of any scattered cumulus.

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. In
addition, the 12z guidance does show some mid level forcing late
tonight, but the airmass is likely too dry to support rain. The
gfs is being discounted at this time. However, there is likely
going to be an increase in clouds overnight.

Overnight lows will be just below normal, ranging from the mid
50s inland pine barrens region of long island to the mid 60s
nyc metro.

There remains a moderate risk for the development of rip
currents into this early evening.

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.

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 20z Monday through Saturday
Vfr through the TAF period with high pressure south and east of
the terminals.

Winds will gradually back to the s-sw into this afternoon with
speeds increasing to around 10 kt. Afternoon sea breezes have
developed across the at coastal terminals with speeds 10 to 15
kt. Winds will gradually diminish overnight.

There is a low chance for a shower or storm NW of nyc metro
terminals this afternoon evening.

A trough will push across the region on Tuesday. Despite an
increase in cloud cover, conditions will remainVFR. Winds will
be from the southwest, with afternoon gusts into the upper teens
to near 20kt.

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.
