Synopsis
High pressure builds into the region tonight and weakens
Tuesday. A cold front moves across the area Tuesday night through
Wednesday morning. This will be followed by a weak upper level
disturbance on Thursday. A frontal system and associated low
pressure will then impact the area over the weekend.

Near term until 6 am Tuesday morning
The forecast is mainly on track. Made some adjustments to hourly
temperatures to capture the latest trends. Also adjusted low
temperature forecast for spots adjacent or close to the pine
barrens region in eastern long island.

The main upper level jet remains south of the region tonight
into early Tuesday.

For tonight, continued subsidence will allow for clear sky
conditions to continue. The winds will continue to decrease in
response to a decreasing pressure gradient. High pressure will
continue to build in from the west. A series of lows will be
moving along a cold front well out into the atlantic. Lower
teens for pine barrens and interior locations to near 30 for nyc
will be the range for the low temperatures.

The conditions will be ideal for radiational cooling with the light
winds and clear sky conditions. Used a blend of met and ecs for low
temperatures, favoring relatively colder guidance.

Short term 6 am Tuesday morning through Tuesday night
The main upper level jet remains south of the area Tuesday
through Tuesday night.

For Tuesday, high pressure weakens with surface winds becoming light
and variable. The winds will eventually settle to a SW direction by
mid to late Tuesday afternoon. Weakening low pressure approaches
from the great lakes late in the day with an associated cold front.

This cold front moves across Tuesday night with winds becoming more
nw behind it. Temperatures Tuesday will be near to slightly colder
than the previous day with limited vertical mixing and some
more clouds contributing to the decreasing trend.

The weather remains dry Tuesday through Tuesday night with just an
increase in clouds Tuesday afternoon into Tuesday night. Mostly
westerly flow in the atmosphere will limit the amount of moisture
available to the low pressure moving across. A shortwave will be
moving across from northwest to southeast. The low pressure and
front will move across with the pressure gradient remaining weak.

Forecast lows Tuesday night were a blend of mav met ecs,
ranging from the lower 20s to lower 30s.

Long term Wednesday through Monday
Complex interaction between multiple streams and pacific energy
will make for a challenging forecast with respect to the timing
and intensity of a frontal system that will impact the area for
the upcoming weekend. Thermally, guidance is all in good
agreement that whatever scenario pans out it should be an all
rain event. Differences arise amongst the global models due to
wavelength spacing between pacific energy moving into the west
coast at the end of the week and an upper low over the lower
mississippi valley. In addition, a northern stream shortwave
passing to the north across eastern canada poses some influence
as well. Rain from this system will work into the area late
Friday and continue into Saturday. The overall evolution and
timing of this system will also dictate how much of a player it
could be on Sunday, but emphasis at this time is on the first
half of the weekend.

Prior to that, an exiting northern branch shortwave will send a
reinforcing cold front through the area Wednesday morning. On
its heels, warm advection ahead of another shortwave trough may
produce flurries on Thursday. This feature though dampens out
in the building ridge ahead of the aforementioned storm system.

Temperatures remain below normal through Thursday. Warm
advection then ensues Thursday night through Saturday as
temperature return to above normal values. Cold advection on the
backside of the departing low Sunday into Monday will bring
temperatures back to seasonable.

Aviation 00z Tuesday through Saturday
MainlyVFR conditions through the TAF period. Some sct-bkn
clouds around 3000 ft are possible aft 00z wed.

Winds becoming lgt and vrb tngt. Around 16z on Tuesday, winds
shift to SW and increase to near 10kt.

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.
