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.

GMZ600 Synopsis For Destin Fl To Pascagoula Ms Out 60 Nm Including Mobile Bay- 407 Pm Cdt Tue Aug 22 2017
Synopsis..High pressure will continue over the north central gulf through mid week then weaken from west to east in response to a developing area of low pressure or the remnants of harvey tracking northward over the western gulf. As a result increased swell from the developing low center will begin to propagate east and north over the north central gulf and marine area late in the week and over the weekend. All marine interests should stay tuned to the national hurricane center and their local forecast office in mobile for further updates on this area of low pressure moving into the western gulf later in the week.

Discussion Updated for latest aviation discussion below.

Aviation
00z issuance... MainlyVFR conditions expected overnight with
isolated showers developing near the coast during the early
morning hours. Scattered showers and thunderstorms will develop
late Wednesday morning and continue through the afternoon. MVFR to
ifr conditions will be possible in and around showers and
thunderstorms. 13

Prev discussion issued 400 pm cdt Tue aug 22 2017
near term now through Wednesday ... Latest satellite loops
continue to show a broad upper low centered over the western gulf
with deep moisture on the eastern side advecting northward, which
is mostly associated with the remnants of harvey over the western
caribbean. To the north along the northern gulf coast deep
moisture will continue to remain in place for the next 24 hours
possibly enhanced overnight through Wed from the better moisture
advection moving northward well offshore. Unfortunately, this
pattern doesn't reflect well with the latest high res data though
we currently have plenty of high cloudiness over the lower half of
the forecast area. For the remainder of today with the high
cloudiness over much of the lower half of the forecast area
afternoon temps have not rebounded as much in these areas likely
leading to better coverage of showers and thunderstorms generally
over the northern half of the forecast area late this afternoon
through early this evening. Aloft broad upper ridge stretching
from east to west will continue over the northern gulf states and
adjacent gulf waters through Wed afternoon resulting in mostly
isolated to scattered coverage of showers and thunderstorms
through early this evening, continuing along the immediate coast
and offshore overnight and early wed, then spreading inland with
slightly better coverage over northern sections of the forecast
area late Wed morning through Wed afternoon. Latest model
soundings continue to show the deep moisture through Wed afternoon
with moderate instability and lapse rates noted in the boundary
layer both this afternoon and late wed. With this a few strong
thunderstorms still could be possible this afternoon and late wed
afternoon with gusty straight line winds, very heavy rainfall and
frequent cloud to ground lightning being the main concerns.

As for temps had to make a few adjustments to this afternoons temps
due to more cloud than expected. For tonight lows will be a tad
higher than previous nights ranging from the mid 70s inland and the
mid to upper 70s along the immediate coast. Highs Wed will be
similar to today ranging from the upper 80s to lower 90s to the
south and the lower 90s to the north. 32 ee
short term Wednesday night through Friday night ... High pressure
builds over the central gulf as the upper trough over the western
gulf finally merges with a passing shortwave in the broad eastern
conus trough. At the surface, a weak front approaches from the
north and stalls across the local area, providing additional
focus for more scattered to numerous showers and thunderstorms
each afternoon in the persisting moist and unstable summertime
environment. Temperatures continue to run in the upper 80's to
low 90's each afternoon and low to mid 70's each night.

Another feature to note in the reorganization of invest harvey
into a tropical system in the bay of campeche. Latest model
guidance has become more consistent in tracking any future
tropical system northwest into the western gulf, reaching
somewhere along the northeastern mexico or texas coastline
Friday. This system could play a big role in weather over our
local area heading into the long term. 49
long term Saturday through Tuesday ... The wet pattern continues
through the weekend as the weak boundary stalled across the area
washes out and a series of weak impulses in the northwest flow
aloft continue to act on a typical hot and humid summertime
airmass below. Well to our west, whatever future system invest
harvey becomes will likely be impacting the western gulf and
northeast mexico texas coast through the weekend. As we head into
the early part of next week, models are beginning to more
consistently suggest that the system gets snagged by the upper
longwave trough over the eastern CONUS and swings northeast across
louisiana. The biggest impact this solution would present to our
area is heavy rainfall, given its track and long fetch of tropical
moisture over the western and central gulf. As the system tracks
northeast into the lower mississippi river valley, it begins to
take on more sub-tropical characteristics, with the ensuing setup
potentially supportive of severe weather over our area as well
during the middle of next week.

That all said, these model solutions are all based off the
assumption of invest harvey's redevelopment into a tropical
cyclone, as well as a particular positioning of mid- and upper-
level steering mechanisms in the mid-latitudes (read: ridges and
troughs). On top of that, model guidance can be notoriously bad
at handling tropical systems that have not yet formed, so these
solutions still remain a bit uncertain at this time. However,
enough model consistency has been introduced run-to-run over the
past few days to warrant a close watch, especially as things begin
to materialize in the bay of campeche through the near and short
terms. 49
marine... Broad upper ridge will continue over much of the northern
gulf through early Thu then begin to break down from west to east
later in the week and over the weekend as the remnants of harvey
move over the western gulf. At the surface weak high pressure will
continue to stretch west over the eastern and north central gulf
through late Thu morning then break down from west to east through
the remainder of the forecast period. From late in the week and over
the weekend the forecast will depend on the track of the remnants of
harvey which now have a 100 percent chance of regenerating into a
tropical system late in the week or over the weekend. For now we
will gradually increase winds and wave heights, generally from the
southeast and south, over the weekend and into next week with
possible swell heights reaching 4 to 5 feet by early next week. All
marine interests along the coast should keep abreast on the current
forecast from the national hurricane center and your local forecast
office in mobile al. 32 ee

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.
