Synopsis
A warm front will slowly lift through the tri-state region
today. A cold front with a wave of low pressure passes through
the region Tuesday night. High pressure builds in for
Wednesday and Thursday, and shifts offshore Thursday night. A
low pressure system approaches from the central united states
Thursday night and impacts the region Friday and Saturday. High
pressure returns for Sunday.

Near term /until 6 pm this evening/
With the areas of light rain across the nyc metro, into
northeastern new jersey and into the lower hudson valley and
southwestern connecticut have increased probabilities to
categorical.

Drizzle will continue this morning, with increasing lift
allowing for areas of steady rain to continue through this
morning. Any clearing will be difficult this afternoon behind
the front, with significant moisture at or below 4000 ft
depicted by the models. This will keep the area from warming up
to MAX potential, and therefore limiting instability.

Regardless, there could be enough support from the upper jet to
produce some showers this afternoon into the early evening after
the frontal passage. A broad model consensus was used for
temperatures today, with an emphasis given to the raw model
output.

Short term /6 pm this evening through 6 pm Tuesday/
Convergence aloft in the dry layer does not seem conducive to
much rainfall tonight. As a result, only low chances for rain
were included in the forecast. If rain does develop, it may turn
out to be mainly sprinkles or light drizzle. Surprisingly big
differences exist between the NAM and GFS for Tuesday. The nam
holds off on the deep lift, and therefore the bulk of the rain,
for the entire day. The GFS brings in rain by morning. The ecmwf
supports the nam, by keeping the bulk of the rain with the main
shortwave. The GFS appears to be kicking off convection over
pennsylvania that brings residual energy in. The forecast sides
with the drier solutions, although there may be some showers or
pockets of light rain with weak vorticity advection and a moist
airmass. A blend of the models was used for temperatures.

Long term /Tuesday night through Sunday/
A southern stream shortwave over the oklahoma and kansas area
this Monday morning will weaken and track to the mid atlantic
coast Tuesday and offshore Tuesday night. Meanwhile, a northern
stream longwave trough moving through south central canada moves
east and passes into northern new england Tuesday night. There
is still some differences in whether or not the two systems will
phase, with consensus for the south stream to be more
progressive and remain separate, and farther south than other
models, while dampening and exiting the mid atlantic. The
southern movement will keep an associated warm front to the
south. This southern and separate solution has been the trend
the last several runs. With higher confidence in precipitation
affecting the area, mainly the southern half of the cwa, will
have likely probabilities Tuesday night.

A northwest flow will persist across the region as surface
high pressure builds to the north and the upper northern stream
trough moves slowly off the northeast coast through Thursday
night. The surface high weakens Thursday night as another
southern stream shortwave approaches, however the upper ridge is
holding with the axis shifting east of the area Friday. The
southern stream system will also be weakening as the wave tracks
east. Have brought in chances late Thursday night into Friday
and this may be too quick if the ridge holds. The weakening low
will re develop off the mid atlantic coast Saturday with chances
of precipitation remaining into Saturday night. Cold air will
be in place across the northern tier and some of the
precipitation may fall as snow or a rain snow mix.

Weak high pressure returns for Sunday into Monday.

Aviation /12z Monday through Friday/
A warm from approaches from the south for late this morning.

This front will lift slowly through during the late
morning/early afternoon hours, possibly washing out across or
just north of the area.

Lower ceilings, drizzle, and fog continue this morning with
widespread lifr at most terminals for the morning push.

Ifr conditions could last through much of the period, especially
to the north and east of the nyc terminals due to the
uncertainty with the timing and final placement of the warm
front. Low level wind shear for most terminals for the mid to
late morning. Confidence has lowered regarding improving
visibilities and ceilings from 18z to 22z across most terminals.

In any event ceilings and visibilities will be low again for
Monday night into Tuesday morning with exact timing and
magnitude in question.

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.
