What's New / NOTES
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.
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.

Synopsis
High pressure builds in from the west through tonight, then
remains over the region into Monday. A coastal low will likely
affect the region the middle of next week.

Near term until 6 am this morning
Forecast is on track with only minor changes made.

An upper longwave trough along the eastern canadian coast and
extending into the northeast remains through tonight with a
northwest cyclonic flow. Meanwhile surface low pressure along
the canadian coast tracks northeast as high pressure builds to
the west. The atmosphere will remain dry and cloud-free tonight.

Winds will be diminishing, and likely decouple late tonight.

This will allow for good radiational cooling with clear
conditions. Inland areas will likely see patchy to areas of
frost and included in the weather forecast. However, the spring
frost freeze program has not begun across these areas.

Short term 6 am this morning through 6 pm Sunday
The upper trough remains across the northeast through Saturday
night as the center of the surface high builds into the
northeast. The weather will remain quiet and cloud free.

Cyclonic flow and weak cold advection continue through Saturday
night, however, the airmass will be modifying under full sun,
and highs Saturday will be approaching normal levels. Saturday
night will be cloud-free with light winds and again there will
be ideal radiational cool conditions. So, expect areas and
patchy frost inland.

Long term Sunday night through Friday
Upper air pattern will very much resemble early springtime
as an upper low over the mississippi valley slowly works east
on the heels of a departing northern branch trough over the
northeast. Ridging both aloft and at the surface builds across
the region to start the week but then gives way to the
aforementioned southern branch close low. The system will lift
northward in response to a northern branch shortwave trough
moving into the upper midwest and great lakes, sending surface
low pressure up the eastern seaboard Tuesday into Wednesday.

Overrunning rains are forecast to develop across the area
Tuesday night and continue into Wednesday night. There are
some differences thereafter though with the global models as
the ecwmf is more progressive with this system and dries things
out for the end of week, while the GFS and ggem close off the
northern branch trough with unsettled conditions lingering until
a cold frontal passage Friday night. Thus, will maintain a
low chance of showers for the end of the week. The point to be
made here there is clearly uncertainty in the guidance for the
end of the week as northern branch shortwave energy dives
southeast across the upper midwest and great lakes region.

However, all the global models are pointing to amplification of
the ridge out west and the trough reestablishing itself across
the east by next weekend.

As for temperatures, much of the period will feature seasonable
temperatures with the exception of Wednesday, where onshore
flow will keep highs several degrees below normal.

Aviation 06z Saturday through Wednesday
High pressure will build in through the TAF period.VFR
conditions are expected. Winds will be near 10 kt or less
through much of the TAF period mainly from W to NW direction.

The winds will initially be NW going into early Saturday and
then back to a more westerly direction during the afternoon with
some SW flow as a sea breeze for some terminals. Also for this
afternoon into early evening, there will be some wind gusts to
15-20 kt. The timing and duration of any sea breezes is
uncertain with wind direction possibly varying about 20-40
degrees comparing observed to forecast for Saturday afternoon.

The timing of the SW flow could also be 2-3 hours off from
forecast.

Outlook for 06z Sunday through Wednesday
Saturday night through Tuesday Vfr.

Tuesday night through Wednesday MVFR or lower conditions
increasingly likely with rain.

Marine
High pressure continues to build into the waters from the west
with the pressure gradient force gradually weakening. Seas on
the ocean waters have subsided to below SCA levels. Also, winds
and gusts were generally below SCA levels, especially across
the open ocean waters. However, through early this evening
occasional nearshore gusts may reach 25 kt. With frequent gusts
and seas below SCA levels the SCA was cancelled.

High pressure will be across the forecast waters Saturday and
Saturday night with winds and seas remaining below SCA levels.

Tranquil conditions are forecast Sunday through Tuesday as high
pressure builds across the waters. However, low pressure moving up
the eastern seaboard Tuesday into Wednesday will result in
increasing winds and building seas with SCA conditions likely to
return by Wednesday morning.

Hydrology
Dry conditions are expected through early next week.

A widespread rainfall is expected for the middle of next week
with the possibility moderate to heavy rain. Predictability is
low on rainfall amounts and hydrologic impacts at this time.

Nyc NOAA weather radio station kwo-35 (162.55 mhz) remains off

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.
