Marine Weather and Tides
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

Low pressure departs the new england coast tonight as weak high
pressure settles over the region. A weak wave of low pressure
passes to the south Saturday into Saturday night. A series a weak
waves of low pressure or troughs will move through the northeast
Sunday through Thursday. A cold front is expected to move
through the region Friday.
Near term until 6 am Saturday morning
Only real change to the forecast this eve was to track the area
of showers moving across SE ct and eastern li. Have increased
pops to cat as a result. Once these move out between 01z and
02z... Things will dry out due to the loss of heating and a
defined source for lift. Otherwise... Only minor adjustments to
winds t TD and sky were needed.
Heights aloft will continue to rise tonight as low pressure
continues to depart the new england coast. Clouds will dissipate
somewhat, but there is enough low level moisture for at least partly
cloudy skies overnight.
Lows will range from the lower 50s inland to the middle and upper
50s near the coast.
Short term 6 am Saturday morning through Saturday night
Main concern for Saturday is with a convectively induced shortwave
that is currently located over the upper mississippi river valley.
Models have not been handling this energy very well as depicted with
dprog dt at h5. However, it appears they are beginning to handle
this feature better with just some timing differences overall. The
shortwave is forecast to quickly traverse through the ohio valley
tonight and then towards the region on Saturday. Prefer to follow a
blend of the nam, 3-km NAM and ecmwf, which brings the shortwave
offshore late afternoon and early evening. The gfs, gefs, and cmc
are a bit slower and do not bring it offshore until overnight
Saturday. Have elected to go with slight chance pops, mainly
for the western half of the area, as better lift and moisture
appears to pass to the south of the region.
Otherwise, mostly cloudy skies are expected with high temperatures
around 70 in nyc and middle and upper 60s elsewhere.
Clouds gradually decrease Saturday night as ridging builds aloft.
Lows will be near normal.
Long term Sunday through Friday
With a delay in the timing of the northern stream longwave
trough and the shortwave rotating through the base of the trough
have delayed the probabilities of showers until late in the day
Sunday; and mainly across the far west and southwest zones.
Aloft, an upper ridge axis will still be west of the region at
12z Sunday with heights rising until the afternoon. At the
surface a weak high will be moving off the coast. Then as the
shortwave moves into the region probabilities increase Sunday
night into Monday. At the surface the will be weak forcing as a
weak cold front moves into the region. A thermal ridge also
moves into the area Monday afternoon. Monday may be one of the
warmer days of next week. With weak surface based instability,
and increasing aloft along with increasing CAPE will have
thunderstorms Monday afternoon into the evening. There is still
some uncertainty with the timing of the upper trough and
shortwave for Sunday and Monday.
The closed upper low and longwave trough will be slow to move
east through the week as a series of shortwaves rotate through
the trough, while at the surface weak lows, or troughs move
through the area. There remains a lot of uncertainty with the
timing and placement of the systems through the upcoming week.
And, there will be a prolonged period of unsettled weather. Will
carry slight chance to low chance probabilities through the
week, although there may be periods of dry weather.
Aviation 20z Friday through Wednesday
Low pressure near nova scotia will move slowly east tonight through
Saturday. Weak high pressure builds into the terminals Saturday.
Vfr. A few isolated showers are possible Saturday afternoon from the
nyc terminals and west and south, withVFR conditions.
Nw wind diminish late tonight and remain less than 10 kt into
Saturday morning. Sea breezes develop Saturday afternoon.

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.
