209 pm edt Thu apr 27 2017
Weak low pressure passes to the east today, while a dissipating
cold front approaches from the ohio valley. The front washes
out across the area on Friday. A cold front approaches Saturday
and pushes south of the area Saturday night. This front then
moves back toward the area as a warm front Sunday night into
Monday with the associated cold front moving through Monday
night into Tuesday morning.
Near term /until 6 pm this evening/
Some gradual improvement continues across the region with fog
becoming more patchy and less dense over the waters but still
across most of the eastern waters. Temperatures are warming into
well into the 60s for most locations except extreme eastern long
island and SE connecticut as clouds lift higher and low levels
dry out. Temperatures and dewpoints remain within a few degrees
comparing forecast and observed values.
The 12z okx sounding confirms the low level subsidence inversion
and with the southerly flow, is helping to keep low level
moisture in place.
Some more breaks in the clouds is forecast this afternoon. It
will be considerably warmer today, with highs in the lower 60s
along the immediate coast, to the lower 70s from nyc north and
west with more of a south to southwest flow.
Short term /6 pm this evening through 6 pm Friday/
Upper level ridge passes to the east this evening as a short
wave trough pivots NE across the ohio valley. The latter of
which will send a dissipating cold front into the area toward
daybreak. Frontal forcing is weak with the mid level short wave
the main source of lift as the front moves into the area. There
is also weak elevated instability with a small chance of a
thunderstorm late tonight into Friday morning. Rainfall amounts
will generally be less than a tenth of inch, but isolated
higher amounts are possible with any stronger convection.
In addition, low-level warm advection and a s/se flow tonight
will likely result in low clouds, drizzle, and fog ahead of the
Conditions clear out from west to east by late Friday morning
with temperatures rising into the 70s just inland from the
coast, and a warm as the lower 80s north and west of nyc. Winds
become SW in the morning with seabreeze development possible in
the afternoon. Temperatures will be about 10 degrees above
Long term /Friday night through Wednesday/
Bermuda type high pressure will set up over the north central
atlantic Friday night into Saturday. This will set up a favorable
flow for warm temperatures, even across coastal areas, as winds
shift to the southwest. High temperatures on Saturday will reach the|
lower to middle 80s away from the coast, lower to middle 70s along
the coast, and upper 60s at the immediate coast. This will also mean
a noticeable increase in the humidity levels as dew points rise into
the upper 50s to lower 60s across the area.
Surface cold front approaches the area from the northwest on
Saturday, pushing south of the region Saturday night. This will mean
temperatures and dew points drop under cold air advection as winds
shift to the north after the cold frontal passage. Zonal flow aloft
will be replaced by upper level which moves in from the great lakes
region Saturday night.
There may be some showers and isolated thunderstorms with the
passage of the cold front, mainly for inland areas as the marine air
over the coastal areas keeps the atmosphere more stable here.
Inland, higher temperatures and higher dew points will mean the
possibility of a shower or thunderstorm before the cold frontal
passage, however, weak ascent will limit activity.
Much of Saturday night through much of the day Sunday will remain
dry as high pressure noses in from southern canada. The cold front
then moves north as a warm front late in the day Sunday into Sunday
night, showers are then once again possible, until the warm front
moves north of the area Monday, then showers with slight chance of
thunderstorms will be possible, until the associated cold front
moves through Monday night into early Tuesday morning. Thereafter,
conditions should remain dry through mid-week as the associated low
pressure heads away from the area.
Aviation /18z Thursday through Tuesday/
A weakening cold front approaches from the west through tonight and
moves into the nyc area around 12z Friday. The front moves slowly
east of the nyc terminals and dissipates Friday morning. High
pressure over the western atlantic builds toward the southeast coast
Variability with ceilings remains through this afternoon, with
mostly MVFR ceilings and unrestricted visibilities. The exception
of kgon where ifr prevails. A brief period ofVFR is possible at
many of the terminals this afternoon before ceilings and
visibilities lower back to MVFR and ifr 22z and later.
Widespread ifr to lifr with drizzle and fog after 02z and then
remaining through tonight. An isolated thunderstorm is possible late
tonight from the nyc terminals and west. Conditions improve Friday
morning as the cold front moves into the terminals. Timing of the
cold front and dissipation remains uncertain.
Winds S to sse 10 kt or less this afternoon into this evening, then
becoming light and variable. Winds shift to west with the passage of
the cold front then come back around to southwest as the front
dissipates. Sea breezes are likely Friday afternoon.

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.
