Marine Weather and Tides
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.
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.

Strong to severe thunderstorms remain possible this afternoon
and evening ahead of a front. After a relatively quiet Friday, a
wet weekend appears likely, perhaps with more strong storms
Near term through Friday
A weak frontal boundary is moving southeastward into the area
and should gradually stall overnight. Showers and thunderstorms
are forming along this boundary as well as along outflow induced
by the ongoing thunderstorm activity. While bulk shear will
increase later in the evening, RUC rap hrrr soundings reveal
fairly pedestrian shear at the moment, and with a fairly
noticeable warm wedge at 20 kft, instability is not really
impressive. CAPE values have jumped into the 1000-2000 j kg
range, but with little positive area aloft and a high freezing
level, this should continue to preclude a hail threat. Further,
with shear generally lagging the boundary and most ongoing
activity, and wind gust potential will likely be fairly pulsey
rather than organized. Thus, while many areas will see
thunderstorms this evening, the risk of severe weather seems
largely diminished at this time.
Convective debris and a soupy boundary layer should keep
temperatures up well above climo at all sites overnight. Fries
Short term Friday night through Sunday
Will hang on to some slight chance pops on Friday across the
southern counties as there is still a touch of uncertainty just
how far south the boundary will be pushed by tonight's
activity. The models also look a touch slower with the next wave
in the northwest flow pattern, and have backed off precip
chances a bit here.
The weekend looks wet, as great lakes low pressure passes to the
north, and several shortwaves run down the northwest flow. Flow
over our area turns more zonal by Sunday, which will slow
progression of the associated frontal boundary. Kept likely pops
going through this period with several rounds of rain expected.
Rainfall totals will have to be watched for problematic areas.
Additionally, there appears to be a risk for severe storm|
Saturday, especially if some cloud breaks can form, given decent
Temperatures will start a slow fall this period, held in check
by the clouds and rain. Minimal changes were made.
Long term Sunday night through Thursday
A general great lakes northeast u.S. Trough will be carved out
by Monday, with this pattern holding into mid-week. Temperatures
will fall back to near or just below normal during this period.
After lingering precipitation Monday, Tuesday and Wednesday
appear dry at this distance. A return to northwest flow may
herald increasing rain chances Thursday.
Aviation 22z Thursday through Tuesday
High confidence forecast save for the onset and duration of
thunderstorms this afternoon and early evening. These times
could vary by 2-3 hours and flight category between 6-12z
An upper level disturbance crossing this afternoon will bring a
line of strong to severe storms moving from north to south
affecting likely all terminals if it develops like many of the
high resolution models indicate. Inserted vcts for all terminals
starting around 20z north and 0z south of the mason dixon line.
Brief restrictions to ifr vis can be expected if an airport is
impacted by a storm. In wake of the storms, last 6-9 hours of
forecast its hard to tell if MVFR fog will develop or will there
be a canopy of stratocu or justVFR? For now, rolled with an
optimistic forecast no CIGS below 030.
Additional rounds of storms are expected through the weekend,
and morning fog is possible as well.

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.
