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 cold front crosses the area this afternoon and evening
followed by high pressure building in through mid-week. A warm
front then approaches from the southwest Wednesday, then slowly
lifts to the northeast into Thursday. A weak cold front will
then approach on Thursday and possibly dissipate over the region
Friday into Saturday.

Near term until 6 pm this evening
Northern stream shortwave ridging will exit to the east by
around midday, as a stronger 700-500 hpa shortwave trough approaches
late in the day. This feature will interact with an atmosphere
that should destabilize fairly rapidly this afternoon,
especially to the N W of nyc. CAPE is progged to reach 1000-1500
j kg by late afternoon over NE nj lower hudson valley interior
sw ct, so should have sufficient dynamics and thermodynamics to
produce mainly scattered showers and thunderstorms this
afternoon. In addition with 40-45 kt of bulk 0-6km shear progged
over this region by late afternoon, plus the region being
progged in the left front quadrant of an 85 kt 300 hpa jet
streak, could see some strong to possibly severe thunderstorms
as well.

The question then becomes for areas outside of the
lower hudson valley NE nj SW ct is how well do the storms hold
together as they head east into areas under a marine influence.

This will determine impacts elsewhere. Storms moving into nyc or
coastal ct by 21-22z have a greater likelihood to be strong or
severe than those moving in around 0z or later.

Still appear on track for highs mainly from around 80 to the mid
80s, except mainly mid-upper 70s near the immediate coast.

There is a high rip current risk at the eastern suffolk county
beaches, and a moderate rip current risk elsewhere.

Short term 6 pm this evening through 6 pm Monday
A cold front passes across the area from west to east early tonight.

Weakening showers and thunderstorms will accompany this front
and h5 shortwave. Along the coast, patchy fog is possible in
the evening ahead of the front, but should scour out overnight
as drier air filters in behind the front.

Lows tonight will range from the lower 60s to the upper 60s per mos
blend.

On Monday, sunshine returns, with perhaps a few more clouds across
eastern locations (se ct and eastern li). A few showers are
possible over these eastern locations, but the bulk of the
shower activity should pass from NW to SE over eastern new
england. This activity will be associated with cyclonic flow as
trough axis pushes east.

Temperatures will rise to the upper 70s to lower 80s.

Long term Monday night through Saturday
High pressure builds Monday night, and NW winds will diminish. With
clear skies and lighter winds, some radiational cooling will take
place across the usual locations.

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 16z Sunday through Thursday
A warm front will slowly move through the terminals this morning,
followed by a cold front this evening.

Gradual improvement occurring mostly as anticipated, except out
east at kisp kgon whereVFR not expect until afternoon.

Scattered showers tstms should accompany the cold frontal
passage late this afternoon into early this evening. Most likely
time frame appears to be 20z-23z kswf, 21z-01z khpn and most of
the nyc metros, 22z-02z kjfk kbdr. Confidence level has
increased enough to mention vicinity impact and cb, but not
enough to get specific in terms of flight cat reductions or wind
gusts. Reasonable worst case direct impact would be brief ifr
vsby and w-nw winds g35-40kt.

Sw to S winds will strengthen through the afternoon, then
become NW following the cold frontal passage tonight. Gusts will
be possible by Monday morning, with flow gradually decreasing
through the day.

Outlook for 12z Monday through Thursday
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
Sub-small craft advisory (sca) conditions are expected on the
waters this afternoon. Isolated gusts to near sca-levels are
possible tonight (outside of any thunderstorms).

Conditions are then expected to remain tranquil Monday through
Tuesday with a relaxed pressure gradient developing over the
waters. Thereafter, the pressure gradient tightens resulting in
a strengthening s-sw flow 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 this afternoon and
evening. However, no hydrologic impacts are anticipated. Areal
average rainfall totals will be under 1 2 inch, but heavier storms
could still produce locally up to an inch.

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

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.
