Synopsis
Low pressure will approach from the south through Thursday, and
pass through late Thursday night, then intensify as it moves
slowly northeast toward the canadian maritimes Friday into
Saturday. High pressure builds to the south and west Saturday
night through Sunday. The high will give way to a cold front on
Monday. High pressure returns Tuesday into Wednesday.

Near term until 6 pm this evening
Adjusted rain chances and amounts during the daytime hours
based on latest radar obs. Expecting rain for most of the
forecast area into early afternoon. Thereafter, just chances of
rain east of the city, and occasional rain likely elsewhere.

Rain will be mostly light to moderate. Any heavier downpour
potential would be brief, and perhaps more likely to occur
towards sunset as better lift and moisture convergence approach.

It still appears that NE nj will likely fall short of ffg
values, so no flash flood watches anticipated for now. Should
any type of flooding occur before sundown, it would more likely
be of nuisance poor drainage variety. Temperatures hold nearly
steady in the 40s.

Short term 6 pm this evening through 6 pm Friday
The storm system will get further north by late Friday night,
especially after 9z, and this is when the rain will taper off
from southwest to northeast. A tongue of drier air will wrap in
quickly behind the departing low during the mid morning on
Friday. The winds will pick up more noticeably towards the late
morning, and especially during the afternoon. Downsloping flow
may allow temperatures to hover around 50 momentarily into the
early afternoon, but then the CAA will get going and
temperatures will trail off late in the day and into Friday
evening. An strong spoke of upper level energy will dive into
the departing storm system and give it another jolt. At this
point the storm will be too far north to impact the region in
terms of any meaningful precipitation, but the storm will
intensify rapidly in the gulf of maine late on Friday and this
will lead to increasing winds due to an increasing pressure
gradient developing over the region.

Long term Friday night through Wednesday
An anomalous upper low with 500 mb height anomalies 2 to 3 standard
deviations below normal moves across the northeast Friday night. The
upper low will lift towards the canadian maritimes on Saturday. The
main surface low pressure, around 980 mb, is progged to be near
maine Friday night. The surface gets captured by the deep upper low
Saturday morning as the system slowly moves the canadian maritimes.

As the upper low moves across the region Friday night, a few showers
cannot be ruled out. Temperature profiles north and west of the city
support the possibility of a few snow showers. The other story will
be strengthening NW winds Friday night into Saturday as the pressure
gradient tightens between the departing low and building high
pressure to the west. Expect sustained winds 15 to 25 mph with gusts
30 to 40 mph late Friday night. Sustained winds may increase a bit
Saturday morning to 20-30 mph and gusts could reach 40-45 mph,
especially at the coast. Thinking the winds should stay under
advisory levels at most locations. Forecast winds in the mixed
layer per NAM and GFS bufkit profiles are strongest Saturday
morning, with weakening winds in the afternoon. This should
translate to weaker sustained winds and gusts 30-35 mph in the
afternoon.

The pressure gradient continues to weaken Saturday night into Sunday
as surface high builds to our south and west. Upper ridging attempts
to build across the ohio valley, but the height field gets suppressed
from another upper low diving south out of southeast canada. This
upper low ultimately stays well to our north and east, but will send
a shortwave and its attendant cold front towards the region on
Monday. Models have come into somewhat better agreement on a wave of
low pressure developing on the front Monday evening as it moves off
the new england coast. The front brings with it a chance of showers
Monday afternoon and evening. There is also support aloft from a
strong upper jet across northern new england. Have increased pops to
high chance for now.

The front moves offshore Monday night with the upper trough axis
following on Tuesday. There is good agreement for sprawling high
pressure to settle over the eastern states for the middle week with
ridging building aloft.

Temperatures will be below normal in the 40s on Saturday, but then
will moderate into the 50s on Sunday and Monday. Temperatures drop
back below normal Tuesday into Wednesday.

Aviation 16z Thursday through Monday
Low pressure approaches from the south today and passes overhead
late tonight.

Easterly winds increase thru this afternoon. Speeds increase to
14-20 kt late today and this evening with gusts 20-25 kt. These
easterly winds back around to the NE N overnight. Low level
wind shear is expected this evening for most coastal terminals
as a 40 to 50 kt jet moves into the area at 1-2 kft.

Ceilings could bounce between 2-4 kft today. However, kgon
could remain rain free andVFR through most of the afternoon.

Rain becomes steadier thru the day, slowly expanding east late
this aftn and eve. MVFR ceilings lower to ifr late in the day
or this evening. These lowering conditions persist tonight, with
lifr possible in spots.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
