Synopsis
Low pressure will slowly move up along the eastern seaboard
through Wednesday night, then head northeast into the canadian
maritimes by the end of the week. A weakening frontal boundary
will dissipate across the area on Friday. Another weak frontal
boundary moving into the area Saturday into Saturday night will
stall nearby early next week.

Near term /until 6 pm this evening/
High pressure to the north and low pressure along the carolina
coast has set up a maritime easterly flow. Warm front associated
with the low will gradually work northward today. As the upper
level low moves north along the eastern seaboard, moisture and
lift will increase through the day.

Stronger isentropic lift and deeper moisture work up the east
coast ahead of the low late this morning and into the afternoon.

Rain and drizzle will be periodic in nature, with some
occasional lulls in activity, but model soundings do show
pockets of elevated h6-9 instability with MUCAPE 200-400 j/kg,
enough for some bands of brief locally heavy showers the first
lifting up into southern ct early this afternoon, then another
developing to the south and west mainly late. Mid level cap
should prevent thunder.

A fairly strong pressure gradient between the approaching low
and the high to the north has brought breezy easterly flow
through the day with gusts 20-25 mph. Temperatures will be in
the 50s.

Short term /6 pm this evening through Wednesday night/
Low level jet and a stacked coastal low will provide good lift
tonight for widespread moderate to locally heavy rainfall.

Pw increases to near 200% of normal with values 1.50 inches.

Models have come into a little better agreement with placement
of heaviest qpf, but it is well known that QPF in models can be
erratic. A very moist air mass, slow moving stacked low, low
level jet, and elevated mid level instability as noted above
support around 0.50-0.75 inches of rain on average across the
area for the first half of the night. The low level jet will
shift to the east after 06z, which will focus the heaviest rain
across eastern long island and southern connecticut.

On Wednesday, the stacked low will be slowly moving south and
east of long island. Rain will continue across eastern long
island and southeastern connecticut, tapering off into the
afternoon. Due to moisture wrapping around the low, cannot rule
out light rain farther west as well.

The close proximity of the stacked low should keep low clouds
around through the day and possibly some patchy fog, so have
gone with the cooler high temperatures in the lower 60s.

It still appears that the entire CWA will fall short of flash flood
and headwater guidance flooding for this event. See the hydrology
section below for more details.

Long term /Thursday through Tuesday/
A dissipating upper low lifts NE along the new england coast at
the onset of the period, otherwise a high amplitude upper ridge
will prevail along the east coast through early next week.

A series of weak frontal systems will converge upon the area,
the first on Friday, which likely dissipates across the area. A
backdoor cold front then may briefly drop south across the area
Saturday night with a confluent flow aloft and shortwave trough
moving over top the ridge across eastern canada. 00z ecmwf
support GFS with the backdoor cold front making it through, even
faster than the GFS on Saturday afternoon. Rain chances in both
cases are low with ridging aloft and a capping inversion in
place. Expect mainly showers, but an isolated thunderstorm is
not out of the question. Strong and/or severe convection is not
forecast at this time.

Front returns north as a warm front Sunday night into Monday
morning with a cold frontal passage Monday evening. There is the
potential for stronger convection along and ahead of the cold
front Monday.

Anomalous upper ridge off the east coast over the the weekend
into early next week will result in above normal temperatures
and muggy conditions, with readings generally in the 70s and
possibly the lower 80s, warmest across the interior. Conditions
will be cooler along the immediate coast. Sunday and Monday may
cool down a bit behind the backdoor cold front.

Aviation /16z Tuesday through Saturday/
Low pressure slowly moves up along the mid-atlantic coastline today
and tonight.

Generally expect ifr conditions, with lifr possible at times
through tonight. Intermittent rain will be locally moderate to
heavy at times today into tonight.

East/northeast winds prevail, with speeds in the 15 to 20 kt range.

Gusts will range 25 to 30 kt this afternoon with some decrease
tonight. Gusts should become less frequent overnight.

Llws is possible this evening with SE winds 45-50 kt at 2kft, mainly
east of nyc terminals.

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.
