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 weak cold front will move south and east of long island early
this morning. Meanwhile, high pressure will build toward the
region through Thursday, then remain through Saturday. Another
frontal system will impact the area early next week.

Near term until 6 pm this evening
Forecast update to reflect latest observations. Just a few
isolated showers across long island for another hour or so,
then drier weather returns for the afternoon.

A cold front will move across portions of the region this
morning. A northern stream trough will remain across eastern
canada and into the northeast once the cold front passes.

Clearing will take place late this morning through the afternoon
as the trough begins to move slowly east, with slowly rising
heights.

Short term 6 pm this evening through 6 pm Thursday
A trough continues to exit the northeast as heights rise across
the region tonight as a strong ridge from the gulf of mexico to
the southern central canadian plains shifts east. The ridge axis
builds toward the area Thursday with a surface high over the
region. A dry NW flow will continue tonight through Thursday.

Despite plenty of incoming solar radiation Thursday,
temperatures are expected to be slightly cooler than Wednesday
as the NW flow brings in a cooler and drier airmass from central
canada.

Long term Thursday night through Tuesday
Vortexes over the labrador sea and northern greenland, and an
upper level trough moving into south central canada at the start
of the period will result in the flattening of the upper level
ridge extending from the upper midwest as it shifts eastward
into sat. This will result in a continuation of the warm and
increasingly humid weather through the first half of the
weekend. Fri will be a bit breezy as the pressure gradient
tightens between low pres to the north and high pres sliding off
the mid atlantic coast. Sat will be the hottest and most humid
day with an established SW flow as a result of the offshore high
remaining anchored over the western atlantic. Temps are
expected to be in the mid to upper 80s under a sunny sky across
much of the local area, possibly even hit the 90 degree mark in
some locations of metro ny nj. The southerly flow off the cooler
waters will result in highs 5-10 degrees cooler along the south
shore of long island and coastal ct.

A cold front will be dropping down from the north on Sat and
while the upper level dynamics appear to remain well to the
north during peak heating, there is the possibility of a few
airmass tstms during the aftn and early eve. A trigger will be
needed and any thermal trough or seabreeze boundary would
suffice. The GFS appears to be overdone with its pcpn field sat
night as sheared energy tracks towards the region from the west
and the front to the north continues to sag southward. Have
maintained schc pops Sat night with the boundary moving into the
local area if not passing through completely by Sun morning.

Global models start to diverge significantly on the details
through the remainder of the period, although the general signal
is for unsettled weather Sun and Mon with the boundary
remaining nearby and a series of shortwaves passing through.

Timing of pcpn will need to be refined in later forecasts once a
there is better agreement.

Another cold front approaches from the west early next week,
although timing is once again in question.

Aviation 14z Wednesday through Sunday
A cold front moves across the area this morning.

A brief period of ifr MVFR conditions this morning, otherwise
becomingVFR.

A light W SW flow at 5 kt or less this morning becomes NW and
increase to around 10 kt. A few gusts into the teens will be
possible this afternoon. Kgon will be in close proximity to a
surface trough today which may keep winds w-sw.

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.
