18z issuance... Scattered shra tsra will continue to develop over
the region through the afternoon before a decreasing trend is
expected into early this evening. The strongest storms will be
capable of producing localized strong wind gusts over 35 knots,
frequent lightning, heavy rain and associated localized MVFR to
ifr conditions. Patchy MVFR fog will once again be possible again
late tonight into early Wednesday morning and have added mention
of br in the local tafs after 10z.VFR otherwise prevails around
the region through the period. 21

Marine... An updated forecast for the marine area was sent to
increase coverage of showers and thunderstorms this morning from
mobile bay southward to the coastal waters from pascagoula to
pensacola out to just beyond 20 nm. Scattered thunderstorms have
developed across this portion in the marine environment.

Conditions have favored waterspout formation and have already
received a report of one over lower mobile bay. Frequent
lightning, brief gusty winds, and locally heavy rain will also
accompany the stronger storms this morning. 21

Aviation...

12z issuance... Patchy early morning fog potential restricting
visibility to MVFR levels (3-5sm) will burn off quickly after
sunrise, followed by increasing low clouds between 1800 to 3000
feet through 17z. Kept vicinity thunderstorms at all TAF sites
beginning at 17z as strong surface heating deepens convection
along the north central gulf coast, and added a tempo group from
18z to 21z for mainly MVFR visibility restrictions due to rain as
a line of thunderstorms pushes inland from the coast. Much of the
rain should move inland away from the TAF sites after 21z. Calm
to light and variable winds this morning will become light
southerly by mid afternoon, but remain variable in and around
thunderstorms. 22
prev discussion... Issued 406 am cdt Tue sep 18 2018
near term now through Tuesday night ... A large portion of an upper
level trough extending down the appalachian mountains to alabama and
eastern mississippi will shift east over the western atlantic as an
upper high pressure system centered over the southern plains moves
over arkansas. The southern portion of the trough however will lag
in its departure as it shifts slowly southeastward over southeast
alabama, the florida panhandle and the northeast gulf of mexico by
late tonight. Weak surface high pressure will remain across the
region, while a east-west surface boundary stalled across the
forecast area is expected to remain.

Strong insolation this morning will allow surface temperatures to
quickly rise into the low to mid 90s by noon resulting in decreasing
stability with surface based capes climbing to between 800 and 1200
j kg inland areas and 1200 to 2000 j kg along the coast. This low
level instability combined with the presence of the upper level
trough and stalled surface boundary will result in mainly scattered
showers and thunderstorms from late morning through the afternoon
hours. A few areas along the i-10 corridor could see numerous
showers and storms early in the afternoon. The combination of
temperatures topping out in the low to mid 90s and high humidity
will result in heat index values ranging from 100 to 105 degrees,
with some localized spots up to 108 degrees mainly along the
immediate coast. Isolated early evening showers and thunderstorms
will dissipate by midnight, but may linger along the coast through
the overnight hours while inland areas see dry conditions. 22
short term Wednesday through Thursday night ... A broad upper
level ridge pushes east across the eastern CONUS through the short
term period. At the surface, high pressure builds into the western
atlantic and northeastern gulf, maintaining a generally light east
to southeasterly flow. Stronger subsidence beneath the passing
upper ridge should keep thunderstorm coverage more isolated and
focused along the sea breeze both Wednesday and Thursday. High
temperatures continue to resemble july rather than mid september,
reaching the mid 90s each afternoon with heat indices surpassing
100 degrees. Low temps stay in the low to mid 70s each night. 49
long term Friday through Monday ... The upper level pattern
becomes a more zonal over the mid-latitudes as we head into the
weekend. A weak inverted trough then develops over the florida
peninsula and retrogrades westward across the eastern and central
gulf. Weakening subsidence due to mid and upper height falls
should support a more scattered coverage of showers and
thunderstorms Friday through the weekend. Storms are still
expected to follow a diurnal pattern, however, and develop
offshore during overnight hours then spread inland each afternoon
and evening. The increase in clouds and rain will keep daytime
temperatures a few degrees cooler, with highs in the upper 80s to
around 90 degrees. 49
marine... Light onshore flow should persist across the coastal
waters and bays throughout the week. Little change in seas is
expected. Isolated to scattered showers and thunderstorms are
possible each day. 22

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.
