Version 3.4
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
A warm front will remain to the south tonight while a wave of
low pressure moves along it. The front will then lift to the
north on Sunday, followed by a cold frontal passage Sunday
afternoon and evening. High pressure will then build in through
mid-week, giving way to a warm front Wednesday night. A weak
cold front will then approach on Thursday and possibly dissipate
over the region Friday into Saturday.

Near term until 6 am Sunday morning
A warm front remains to the south of the region, and a
shortwave will be shifting through overnight, and this may
result in a shower or two in spots. The warm front is expected
to lift towards long island overnight with diminishing chances
of showers and drizzle. There is some elevated instability,
however this remains mainly to our south. Perhaps some
thunderstorms pass within 40-50 miles south of eastern long
island tonight. Have also added some fog to the forecast. Dense
fog cannot be completely ruled out ahead of this warm front, so
this will need to be watched. Temperatures should remain nearly
steady this evening, and rise a couple degrees overnight in some
areas.

Short term 6 am Sunday morning through Sunday night
On Sunday, the warm front should lift north, followed by SW to
wsw flow that will slowly steer a cold front through late in
the day and at night.

Moderate instability builds NW of nyc, and showers and
thunderstorms should redevelop during the afternoon, move east
toward nyc metro, long island, and southern ct from late day
into early evening, then dissipate overnight. Given the combo of
instability and 35-40 kt unidirectional westerly deep layer
shear, storms could produce gusty winds, perhaps an isolated
damaging wind gust.

Lows tonight will remain in the 60s, and warmer temps are
anticipated Sunday as area sits temporarily in the warm sector.

Upper 80s expected for urban NE nj, and lower mid 80s
elsewhere. Lows again fall into the 60s Sunday night.

There will be a moderate rip current risk at the ocean beaches.

Long term Monday through Saturday
High pressure builds in during Monday, but with a cyclonic flow
aloft coinciding with lift from a surface trough and shortwave,
there could be a shower or two across SE ct and eastern li. Partly
cloudy otherwise with near normal temperatures. The high pressure
center moves through on Tuesday with sunny conditions and highs
slightly cooler, but still close to normal.

The high will be to our east on Wednesday, and a return SW flow
will bring warmer and more humid conditions. It appears the
daytime hours for most areas will be dry as showers ahead of an
approaching warm front remain to the west. The warm front moves
through, then a cold front slowly approaches Thursday into Friday. A
surface trough likely forms over the area ahead of the cold front.

It's beginning to look more likely that the front never makes it
through the entire region and instead dissipates nearby sometime
Friday into Saturday. Will maintain slight chance to chance pops
Wednesday night through Friday, then go with a dry forecast
thereafter.

Rising temperatures aloft will allow for highs around 90 in the city
and some inland areas Thursday. 90s then become more widespread
across the tri-state area for Friday and Saturday. A south to
southwest flow along with sufficiently high dewpoints through the
top of the mixed layer would limit the magnitude of surface
dewpoints mixing-out each afternoon. Heat advisory criteria could
therefore be met in this period, particularly Friday and Saturday.

Aviation 03z Sunday through Thursday
High pressure to the north moves through the canadian maritime
into Sunday as waves of low pressure move along a nearly
stationary front south of long island overnight. The front will
begin to move toward the terminals late. A cold front
approaches from the northwest Sunday afternoon and moves through
the terminals Sunday evening.

MVFR to ifr conditions are expected to become widespread ifr
across the region soon after midnight. Periods of lifr, and
locally vlifr, are possible outside of the city terminals
overnight. Conditions slowly improve Sunday morning, becoming
vfr by afternoon. Drizzle and brief light rain will be possible
this evening. Then with the approach of the cold front showers
will be possible late in the afternoon and into the evening.

There is also a chance of thunderstorms mainly to the west and
north of nyc metro terminals.

Winds will be light and variable overnight then become SW to s
in the morning. Sea breezes are possible, however, confidence is
low.

Outlook for 00z Monday through Thursday
Sunday night Vfr with MVFR to possibly ifr, in showers and
isolated thunderstorms early in the evening. Best chance for
any thunderstorms will be to the N W of nyc.

Monday-Wednesday Vfr. Nw-n winds g15-25kt Monday-Monday
night. S-sw winds g20-25kt possible Wednesday.

Wednesday night-Thursday MVFR or lower probable. Showers are
also probable and there is a chance of thunderstorms as well. Sw
winds g15-25kt possible.

Marine
Winds and seas forecast on track with no changes at this time.

An approaching warm front will allow for a weak flow overnight
with a subsequent decrease in seas. Ocean seas could however
briefly climb to around 5 ft daytime Sunday with a building
southerly swell.

Conditions will remain tranquil through Tuesday with building
high pressure. Thereafter, the high shifts offshore with a s-sw
strengthening and sca-level gusts possible on all waters
Wednesday afternoon through Thursday evening. Ocean seas will
increase to sca-levels in response to the strengthening and
prolonged south-southwest flow.

Hydrology
There could be a few locally heavy downpours Sunday afternoon
and evening. However, no hydrologic impacts are anticipated.

Areal average rainfall totals through Sunday evening will be
under 1 2 inch, but heavier storms on Sunday could still produce
locally up to an inch.

No hydrologic impacts are expected from Monday through the rest
of the forecast period.

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.
