Marine Weather and Tides
Springs, 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 tonight and into Monday.

A weak frontal system affects the area from late Monday night
into Wednesday. High pressure returns Thursday and remains
through Saturday. The next weather system will move across the
region on Sunday.

Near term until 6 am Monday morning
Scattered showers have pushed offshore. Forecast remains on
track with just minor updates to temperatures and dewpoints to
reflect current observations. Otherwise, clearing conditions
expected tonight as high pressure builds across the region.

Temperatures tonight will be in the low to mid 50s.

Short term 6 am Monday morning through Monday night
Sunny conditions Monday as high pressure builds across the region
with a weak frontal system impacting the area late Monday night.

This will result in some precipitation across the region with
light QPF values. Highs on Monday will generally be in the mid
to upper 70s, except lower 70s across south coasts with
afternoon seabreeze development. Temperatures Monday night will
be in the mid to upper 50s.

Long term Tuesday through Sunday
A weak frontal system will impacting the area Tuesday through
early Wednesday. There are some small timing differences with
the global models with both the onset of warm advection rain and
the possibility of scattered convection lingering into
Wednesday as the airmass change behind a cold front is subtle.

This does not look to be a significant rainfall event.

Additionally, while the westerlies and an upper trough will
remain across the area through midweek, the instability at this
time looks to be only marginal.

High pressure builds across the area on Thursday 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 00z Monday through Friday

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.
