Synopsis
A cold front will move across tonight. Weak high pressure will
then build in for memorial day. A warm front approaching late
Monday night into Tuesday will remain just south into Wednesday
night as weak low pressure moves along the front just south of
long island. The front may lift through on Thursday, followed by
a cold frontal approach Thursday night. This front may linger
into Friday, then weak high pressure may build in later Friday
into Saturday before a series of weak disturbances approach and
pass through later in the weekend.

Near term until 6 am Monday morning
Cold front draped across the mid hudson valley into northern pa
will move through tonight. Before it does, so, showers and
possibly a stray TSTM over NE pa will move in from the west. As
far as near term mesoscale models, the fv3-nssl had a good
handle on this if a touch slow too far north, so brought this
activity across tonight. Severe wx not expected as occurred with
isolated storms in parts of orange county, and from eastern
passaic SE through bergen into the upper reaches of nyc.

Short term 6 am Monday morning through Monday night
A nearly steady height trend in the mid levels will be
accompanied by weak high pressure building in from the north
and west.

For Monday, the drying trend continues with dewpoints about 5-10
degrees lower than the previous day. The northerly flow will help
promote these drier conditions. The winds will be weak so eventual
sea breeze circulations will likely occur during the afternoon hours.

Expecting a cooler day Monday with backing of winds from low to mid
levels and the several degrees cooler 850mb temperatures which
will be mixed down with daytime heating. A consensus of MOS was
utilized for the high temperature forecast, ranging mostly in
the mid to upper 70s.

The weak high will be moving northeast of the region Monday
night with a slight decrease in the height field in the mid
levels. There will be a warm front that will approach the region
late Monday night. Winds will be light and variable and clouds
for the first half of the night will be few to scattered
coverage before becoming more broken coverage overnight into
early Tuesday. There will be enough radiational cooling to make
for a relatively cooler night than the previous night, with
forecast lows ranging from mostly 50 to 60 degrees.

Long term Tuesday through Sunday
Have made only minor changes to the previous forecast based on
model trends over the past 24 hours. Much of this week should
feature quasi-zonal flow aloft, with flat ridging to the south,
and a series of passing shortwave troughs along with a nearby
sfc warm front bringing inclement wx at times. The first of
these, with an approaching warm front on tue, will feature cool
conditions with highs only from the mid 50s to mid 60s, and
periods of showers, possibly elevated thunder as well Tue night.

This front should remain to the south through at least wed
night, and there are signs it may only lift through part of the
area on Thu per gfs, making the temperature forecast east of nyc
rather uncertain (60s vs 70s). A cold front should follow late
thu, and the trend calls for slower timing, which if it pans out
could limit potential for strong to severe tstms.

Forecast details become murkier going forward from Fri into the
weekend. GFS continues to lag the cold front behind on fri, so have
mentioned chance of showers and possibly a TSTM for the daytime hrs.

Dry wx seems likely to follow for Fri night into at most of Sat via
weak passing high pressure, but then with a broad upper longwave
trough setting up over eastern north america and continued train of
shortwave disturbances passing through it, have slight chance pop
for late day Sat int Sunday morning, and higher chances late Sunday
into Sunday night. Above normal temps appear to be the rule in this
time frame per MOS guidance.

Aviation 02z Monday through Friday
A cold front passes tonight with high pressure returning on
Monday.

A few light showers are possible around the city terminals
through 04z with otherwiseVFR conditions through the taf
period.

W-sw winds 10 kt or less will continue until the cold front
passage at around 04z with NW winds expected overnight. Some
outlying terminals could go light and variable overnight. Winds
veer to the N and NE early Monday morning and then remain
northerly into Monday afternoon under 10 kt. S-se seabreezes are
expected for south coastal terminals in the afternoon. Winds
diminish Monday evening.

Outlook for 00z Tuesday through Friday
Monday night Vfr.

Tuesday MVFR or lower in likely showers. E gusts to 20 kt
possible near the coast.

Wednesday-Friday Chance of MVFR or lower in
showers thunderstorms, mainly in the afternoon and evening each
day.

Marine
The pressure gradient is expected to remain relatively weak
through Monday night with conditions staying below SCA criteria.

Wind gusts are expected to remain near or below 20 kt. Ocean
seas are forecast to stay between 2 to 4 ft through tonight and
then between 2 to 3 ft Monday through Monday night. Non-ocean
waters are forecast to be around 1 ft or less through the short
term through Monday night.

Still expecting quiet conds with respect to prevailing
winds seas through the longer term. Tstms may also pose a hazard
at times during mid week, especially on thu.

Hydrology
Rainfall from late Mon night into Tue night should average from
1 2 to 3 4 inch. Up to another half inch may be possible late
day Thu into Fri morning.

Equipment
Nyc NOAA weather radio station kwo35 (162.55 mhz) remains off
the air.

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.

In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
