What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
Low pressure will track southeast of the region today, allowing
high pressure to build in from the north on Friday. A warm
front passes early this weekend, then is followed by a cold
front later this weekend. High pressure builds next week.

Near term until 6 pm this evening
Low pres was analyzed just N of acy at 7z. The low will slowly
track ewd today. This will bring an end to the rain from W to e,
with the heaviest pcpn over LI where it appears the best mid
lvl frogen is located based on radar. The cloud shield extends
out to cntrl pa, so it will take some time to clear things out
completely. Timing for mostly sunny looks to be about 15z port
jervis area, to as late as 20z montauk. The NE flow is progged
to be blw 10kt, and with h85 flow falling blw 15kt at 18z, a sea
breeze is possible. The model consensus is for the flow to veer
to around 100 degrees, but it would not be surprising to see
spots along the immediate S coasts to go closer to true sea
breeze direction. The nbm was used for temps.

Short term 6 pm this evening through 6 pm Friday
High pres builds into NRN new england tngt, and there is a
suggestion that some marine stratus flows in from the e. The
nam is much more aggressive than the gfs, which is typical, but
the GFS has a significant amount of cirrus as well, which is
supported by the current water vapor imagery. As a result, the
fcst is ptcloudy, with room for upward adjustment based on the
evolution of the marine stratus and eventual thickness of the
cirrus. Increasing clouds from the S then on Fri as SW flow
aloft develops. Increasing thetae could support a few shwrs,
particularly late in the day across the swrn portion of the cwa.

Pops have been limited to slight chc however in line with the
model consensus data. The NAM holds firm with the high resulting
in dry wx. The nbm was used for temps, with cooler highs due to
onshore ely flow.

Long term Friday night through Wednesday
Closed upper low opens as it traverses across the great lakes region
and into new england this weekend. Models are in overall agreement
on main features, with details still differing somewhat.

In general, warm front approaches Friday night, with a wave of low
pressure riding along the front, passing south and east by Saturday.

Ridging from the northeast could result in drier conditions,
providing subsidence and stability, with persistent onshore flow
prevailing north of the front, and wave.

However, the upper low and trough are progged to open up as
mentioned and broaden as the system lifts towards the great lakes.

The main upper trough axis swings through Saturday evening and
Saturday night leaving behind a westerly flow on Sunday. Another
upper trough should cross the region Sunday night into Monday,
finally taking the frontal system offshore.

Will maintain previous forecast of gradually increasing pops on
Friday night into Saturday morning. Chance coverage to
likely numerous coverage for showers. Meager instability noted, so
thunder chances remain quite low Saturday.

It appears at this time the best forcing will be with the upper
shortwave axis and passage of the warm front Saturday evening into
Saturday night, so showers thunder possible during that time frame.

Conditions should dry out Sunday with the region fully in the warm
sector. Westerly flow aloft and a much drier middle and upper
atmosphere prevents anything more than a chance for showers and
thunderstorms with a cold front nearby. The chance for showers and
thunderstorms continues into Monday morning with the upper trough
axis passing across the area eastern new england. Drier weather
returns Monday per 00z model suite.

While the weekend certainly does not look like a washout, there will
be periods of showers and possible storms Saturday night into
Sunday. Locally heavy rainfall is possible in any convection.

High pressure returns behind the upper trough and frontal
system moving offshore on Monday. The high will be in control
through the middle of the week.

Temperatures average below normal Saturday and then above normal on
Sunday. Temperatures should then average near normal for next
week.

Aviation 08z Thursday through Monday
A wave of low pressure approaches from western pennsylvania,
passing near or just south of the terminals during the overnight
hours. A backdoor cold front moves into the terminals toward
00z Friday.

MVFR conditions in rain expected through the early morning
hours. Periods of ifr conditions are possible in any heavier
pockets of rain, primarily across the nyc and coastal terminals.

Rain then tapers off from west to east between 09z and 12z, with
conditions improving toVFR thereafter.

Light and variable winds overnight return out of the N to ne
around daybreak as the low passes to the south and east. NE to
at times E winds then continue through the day at around 10 kt
before diminishing tonight.

Outlook for 06z Friday through Monday
Thursday night and Friday Vfr.

Saturday Sub-vfr. Showers likely, possibly a thunderstorm
during the evening and nighttime hours.

Sunday Chance of sub-vfr conditions in showers and
thunderstorms.

Monday Chance of showers early, becomingVFR.

Marine
Light NE winds will develop today behind a departing low. Winds
and seas will remain blw SCA lvls thru tngt. Increasing ely flow
will build seas to near SCA lvls on the ocean fri. Elsewhere,
winds will remain blw 25kt.

A frontal system is expected to impact the waters this weekend.

While gusts to 20 kt are possible, generally expect wind gusts to
remain below 25 kt through the weekend.

Easterly winds shift to the sw, then west as the weekend progresses.

By Monday, winds turn to the NW behind a cold front.

Ocean seas may build to 5 ft this weekend as a warm front moves
north and SW flow increases further. Otherwise, seas remain generally
in the 3 to 5 ft range, with 1 ft or less on the non ocean waters
this weekend into early next week, except extreme eastern LI sound
and the entrance of the ny harbor.

Hydrology
Around a half inch of additional rainfall is expected this mrng
across ERN li. Otherwise, rainfall of a quarter inch or less is
expected elsewhere. Locally heavy rainfall is possible this
weekend, especially late Saturday into Saturday night. However,
no significant widespread hydrologic impacts are currently
expected.

Equipment
Nyc NOAA weather radio station kwo-35 (162.55 mhz) remains off
the air for an extended period of time.

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.
