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
Coverage for showers remains widely scattered at most late this
afternoon NW of nyc. Meanwhile, patchy drizzle continues across
parts of long island and southern ct where temp dewpoint
depressions have been lower.

Passing upper shortwave along with warm front and sfc wave of
low pressure approaching the coastal locations may result in
somewhat higher coverage of showers this evening, with chance
pop. The warm front should lift toward long island overnight,
with any showers departing late.

Lows will be in the 60s.

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 22z Saturday through Thursday
High pressure retreats to the northeast into Sunday, as waves
off low pressure pass to the south of long island. A cold front
approaches from the northwest Sunday afternoon.

MVFR to ifr ceilings this afternoon, becoming ifr throughout
by around midnight. Periods of lifr are possible outside of the
city terminals overnight. Conditions should improve to MVFR by
mid-late Sunday morning. Confidence in showers occurring at any
given terminal this evening has decreased, so have removed the
prevailing showers from the TAF and left as vcsh mainly through
this evening.

Winds become light and variable throughout by evening and
remain so into Sunday morning. Seabreezes develop at coastal
terminals towards midday on Sunday, with a SW flow at under 10
kt at inland terminals.

Outlook for 18z Sunday through Thursday
Sunday afternoon night MVFR or lower possible through
evening, with showers and possibly a thunderstorm as well. Best
chance for any thunderstorms mainly 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
An approaching warm front will allow flow to weaken tonight
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.

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.
