Synopsis
Strong high pressure will build in from the west through
Wednesday night. The high will then retreat northeast from new
england into the canadian maritimes Thursday into Thursday night
as intensifying low pressure moves up the coast. The low will
pass through on Friday, and then head northeast past the
canadian maritimes on Saturday as high pressure builds to the
south and west. A cold front will pass through on Sunday,
followed by another frontal system Sunday night into Monday
night.

Near term until 6 am Wednesday morning
The forecast remains on track this evening with only minor
changes to account for the latest trends in temperatures and dew
points.

There could be some sprinkles into the early evening hours as weak
lift pushes through and interacts with remnant moisture. High
pressure otherwise builds in from the west tonight with a fairly
tight pressure gradient in place over the region as low pressure
deepens over the canadian maritimes. Breezy conditions will result,
and with a strong jet streak not too far to our north, plenty
of cirrus should remain into the late night hours after lower
and mid clouds scour out in the evening. The combination of
clouds and winds will prevent frost formation, so no frost
advisories are planned at this time. Lows in the low to mid 30s
across coastal sections and 25-30 inland.

Short term 6 am Wednesday morning through Wednesday night
Deep-layered ridging occurs on Wednesday with high pressure building
in, then the high shifts towards new england Wednesday night with a
continuation of dry weather and primarily cirrus streaming through
from time to time. Temperatures will continue to be seasonably cold
with both high and low temperatures averaging 10-15 colder than
normal. Wind chills will still be as low as the upper 20s to lower
30s even during the warmest part of the day. Most guidance shows
lows in nyc in the upper 20s or around 30, so will issue a freeze
watch for the remaining boroughs where the growing season has not
yet ended. Lows otherwise range downward into the teens across the
northern suburbs and the pine barrens region.

Long term Thursday through Tuesday
Main focus remains with the retreating high and approaching
coastal storm Thursday into Friday. Big picture remains much the
same as with the previous forecast, as a mid 1030s high retreats
ne, and as an upper low moving across the oh tn valleys spins up
sfc low pressure along the SE coast, which then heads up the
coast to a position along the jersey shore by 12z fri. The front
end of the storm holds the greatest concern as far as wintry wx,
as cad via the retreating high continues to supply cold air,
with snow likely all the way down to the coast on thu, perhaps
an inch or two for western long island, nyc metro, and coastal
ct before precip changes to rain by Thu evening. A more complex
scenario likely farther inland, as sfc temp remain AOB freezing
while warmer air moves in aloft on SE h8 flow, with primarily
an advy level snowfall of 2-3 inches, changing to sleet and then
freezing rain of less than 1 10 inch accretion during thu
night. ATTM probabilistic guidance indicates only a 10-20
percent chance of higher snow ice amts than currently fcst,
with MAX potential for 5-7 inches of snow and 1-2 tenths of an
inch of ice across the i-84 corridor in the lower hudson valley
and ct, also extending down into W passaic, and northern
rockland westchester.

Temps should warm enough during Fri morning to change precip to
all rain except perhaps in the highest elevations north west
of nyc.

This storm is still a couple of days away, so track and timing
changes are possible and could result in further changes to the
fcst.

For the weekend, a cooling trend as another shot of cold air comes
in for sun. Another frontal system should pass through with chances
for rain snow showers from Sunday night into Mon night. &&

Aviation 00z Wednesday through Sunday
Canadian high pressure builds into the region through early
Wednesday evening.

Vfr through the TAF period, except for a brief period of MVFR
possible at kisp through around 1z.

Nw winds through the TAF period. Winds become gusty throughout
at all terminals by mid evening, with g20-25kt. Gusts should
abate by around 8-9z with sustained winds around 10-15kt. Gusts
resume around 13z with g around 20-25kt. Gusts should abate
around 22z with speeds around 10kt.

Ny metro enhanced aviation weather support...

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.
