Synopsis
Weak high pressure north of the region tonight will slides east
early Friday morning. Another wave of low pressure moves across
the region Friday and Friday night. A warm front moves north
Saturday night into Sunday, and a cold front passes late Sunday.

High pressure builds early next week.

Near term until 6 am Friday morning
A weak shortwave slides east tonight, with precipitation coming
to an end. The majority of the precipitation remains rain,
however thermal profiles continue to indicate the potential for
some sleet snow as the precipitation comes to an end, mainly
north of nyc. Across nyc and long island, all rain is expected.

All precipitation end by midnight with the remainder of the
night dry. It will remain mostly cloudy with lows falling into
the upper 20s and lower to mid 30s.

Short term 6 am Friday morning through Friday night
Next focus of attention is another wave of low pressure which
moves across the region Friday afternoon and Friday evening.

Precipitation spreads from west to east Friday morning, with
all areas seeing pcpn during the afternoon. 12z thermal profiles
support rain for the most part, however there is a chance that
western orange county can pick up a couple hours of freezing
rain. A lot of this will depend on the timing of the
precipitation moving into the area. If the precip moves in
slightly faster than forecast, there will be a greater threat
for freezing rain. If the precipitation holds off til mid to
late morning, there is a chance that surface temperatures could
reach freezing, lowering the threat of freezing rain. Right now
do not have the confidence and coverage to go with an advisory,
and will let subsequent shifts assess trends and issue any as
needed.

Temperatures are then forecast to warm enough for all rain by
afternoon. Rain continues in the evening, with drier weather
expected for Friday night. With a frontal boundary remaining
near the region Friday night, will leave at least a slight
chance of rain showers in the forecast, along with the potential
for some patchy fog.

Highs on Friday climb into the upper 30s and lower to mid 40s,
with temperatures only falling a few degrees for Friday nights
lows.

Long term Saturday through Thursday
A warm front moves north toward the area Saturday night into Sunday.

Showers are possible during the day on Saturday with temperatures in
the low 50s. Low pressure will track northeastward across the upper
great lakes on Sunday while its associated cold front is expected to
move through the area on Sunday. This will result in rain chances
across the entire region with less than three quarters of an inch of
precipitation. Temperatures on Sunday will be in the upper 40s to
lower 50s.

High pressure then builds Monday through Wednesday, with dry
conditions expected through the middle of the week. A low pressure
system approaches the area Thursday.

Temperatures will remain in the upper 40s to lower 50s with lows in
the low to mid 30s Monday through Thursday.

Aviation 22z Thursday through Tuesday
A weak wave of low pressure tracks well south of the terminals into
early this evening as high pressure builds to the north.

High pressure moves off the northeast coast Friday as another
wave of low pressure approaches from the west.

MVFR conditions as periods of light rain continue into early this
evening. Light rain is expected to transition to rain and sleet late
in the day into the evening from the north and west to the south.

There is now more uncertainty as to how much sleet will mix with
the rain toward the coast, before the precipitation ends. Confidence
in ice pellets sleet occurring is lowering.

MVFR ceilings remain tonight, with ifr ceilings east of the nyc
terminals. Ifr develops across all the terminals by late Friday
morning as light rain moves back into the region, with light
freezing rain beginning at kswf.

Ne wind 10 to 15 kt diminishes after 00z. Winds then become E to
ne Friday.

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.
