Aviation
Mostly clear skies and excellent vsbys are expected through Monday
night, except for some broken high level clouds late in the
period. Stronger north to northeast winds of 15 to 20 knots
sustained at knew and some 15 to 20 knot gusts at kmsy will start
to ease by or shortly after sunrise, then lighter winds will
prevail the remainder of the TAF forecast. 22 td

update...

updated for stronger winds tonight in the coastal waters forecast.

Marine...

north to northeast winds are expected to remain up in the 15 to 20
knots range for much of the night tonight across the tidal lakes,
sounds and coastal waters, so updated the forecast to add "small
craft exercise caution in effect until 3 am cst Monday" headline.

22 td
prev discussion... Issued 337 pm cst Sun nov 19 2017
short term...

strong surface high pressure has built in today with a dry, cool
airmass. Northern and inland areas will be close to freezing
before sunrise Monday so patchy frost is possible in sheltered, low
lying spots. However, light northerly winds will likely act to
keep temperatures from getting too low. Guidance does not have
temperatures getting colder than 33 or 32 degrees across southwest
mississippi and that should only be for a brief period of time.

Monday expect much calmer winds than today, sunny skies, and
daytime highs near 60.

Long term...

more of an easterly flow Monday night and Tuesday will help to
warm temperatures a bit, though clouds will increase from an
approaching trough. Tuesday night the upper trough digs south
across the central gulf coast and another cold front will move
through at the surface. Wednesday will be cool and breezy behind
the front. Dry air and building surface high pressure centered
over eastern kansas and missouri should again provide clearing
skies. In fact, that high pressure will be expansive and result in
favorable travel conditions across much of the country.

Cool and clear conditions continue across the central gulf coast
for thanksgiving with breezy northern winds still near the coast
and over water. Expect temperatures about 5 to 10 degrees below
normal for the holiday. Temperatures will moderate some as winds
calm into the weekend, but still no real chance of rain through
the forecast period.

Krautmann
aviation...

vfr cavu conditions all terminals next 24-30 hours.

Marine...

high pressure moderating over the gulf states with cold air
advection neutralized at this time. This will allow for winds to
lessen overnight while the high moves eastward through Monday. Next
surge comes through mid-week with re-enforcing cold air advection to
maintain moderate northerly winds and high seas. 24 rr

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.
