Port Chester, NY

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
High pressure builds across the region today and moves off the
southern new england coast tonight. A warm front will lift
through Tuesday afternoon followed by a cold front late Tuesday
night into Wednesday morning. High pressure returns behind the
frontal passage and remains through Saturday. Another frontal
system impacts the area on Sunday.

Near term until 6 pm this evening
Current forecast is on track, with only minor changes made to
reflect current conditions.

Ridging builds into the area today providing mostly sunny and
warm weather. Light northerly winds will give way an afternoon
seabreezes at the coast. Highs will generally range between mid
and upper 70s, although a few 80 degree readings will be
possible in metro ny nj. Humidity levels will be much lower than
yesterday, making it more comfortable.

Short term 6 pm this evening through Wednesday
Upper ridge axis shifts to the east tonight as a shortwave
trough over the midwest approaches. Guidance is in good
agreement that pcpn hold off until aft 12z Tue except perhaps in
orange county. Overrunning pattern strengthens as the day
progresses and a warm front lifts into the area. Model soundings
are indicating some weak elevated instability late Tue aftn
through Tue eve, in addition to increasing pwats (maxing out
between 1.50 and 1.75 inches). Any tstms that develop have the
potential to produce a period of moderate to heavy rainfall.

Warm front should lift through the area during the aftn and
early eve as parent low tracks through new england, followed by
a cold front Tue night into Wed morning. High temps are tricky
on Tue and will depend on timing of the warm fropa.

High pres returns behind the cold front with dry weather and a
return to above normal temps on wed.

Long term Wednesday night through Sunday
High pressure builds across the area Wednesday night and
remains through Saturday, resulting in dry weather with above
normal temperatures. A frontal system is then forecast to impact
the region Saturday night into Sunday. Highs on Sunday will be
in the low to mid 70s.

Aviation 15z Monday through Friday
High pressure builds in from the great lakes into this evening,
then moves off the nj coast tonight. A warm front approaches
from the southwest toward Tuesday morning as low pressure moves
into the eastern great lakes.

Vfr through the TAF period. Showers will be approaching kswf
toward 12z Tuesday.

N-ne flow 5-10 kt will become light and variable early this
afternoon, with sea breezes developing shortly thereafter and
into this afternoon at all terminals, except at kswf, where a
light W flow is forecast. Winds become light and variable again
tonight.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
