Synopsis
High pressure builds to the north through the weekend, and across
the canadian maritimes early next week. Low pressure may pass
south and east of the local area during the middle of next week,
followed by a slow moving cold front late in the week.

Near term until 6 am Saturday morning
High pressure builds in from the north. Higher-level clouds this
evening will shift south and east and leave us with a mostly clear
sky for the overnight hours. Dewpoints will continue to fall, and
low temperatures are expected to end up in the 50s for a good
portion of the inland suburbs and the pine barrens region. 60 to 65
for most of the other locations.

There is a moderate risk of rip currents at the ocean beaches
into this evening.

Short term 6 am Saturday morning through Saturday night
High pressure continues to build in on Saturday. Mostly sunny
conditions with highs mostly 75-80 which is a few degrees below
normal. Winds shift to the east Saturday night as the center of high
pressure moves through maine. Low level moisture increases with
clouds probably increasing along the coast late at night. Thinking
is that it remains dry through the night and any potential light
rain or drizzle would hold off until Sunday.

There is a low risk of rip currents at the ocean beaches on
Saturday.

Long term Sunday through Friday
This period starts off with high pressure over northeast
u.S. Southeastern canada at the surface, with a weak upper level low
over southern new england.

A northeasterly flow will allow for abundant low level moisture on
Sunday into Monday morning. This will mean more clouds than Sun with
stratus and drizzle or light rain showers during the period. This
will also mean below normal temperatures thanks to clouds.

Temperatures will only rise to the lower to middle 70s.

Mainly dry conditions are expected Monday afternoon, with the center
of high pressure pushing into the canadian maritimes.

Of some concern is the potential for mainly indirect impacts from a
tropical cyclone that may develop during the mid-week period. This
system is currently over near the florida panhandle, with the
national hurricane center showing a 90% chance of tropical cyclone
development in the next 5 days. Global models agree in this system
developing, and passing well south and east of the area. However,
indirect impacts of coastal flooding and dangerous rip currents are
possible during this time frame, depending on how strong it becomes
and the exact track. There are significant timing differences, and
therefore, uncertainty is fairly high.

A cold front approaches late Wednesday, moving slowly on Thursday.

High pressure builds in for Thursday night into Friday.

Aviation 20z Friday through Wednesday
A cold front settles just south of the region as high pressure
builds to the north.

Vfr through the TAF period. Mid and high clouds are also expected to
move south and skies will become clear tonight.

North to northeast winds around 10 kt through a good part of the taf
period becoming mostly northeast near 10 kt Saturday.

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.
