Discussion
A generally unsettled pattern will prevail through most of the
forecast period. Weak front currently stretching from the great
lakes into central texas will continue to move toward the area
tonight. The front is expected to stall near the coast Monday and
into Tuesday, serving as a focus for showers and thunderstorms.

Thus am carrying likely pops for both days. QPF associated with
this front should be manageable - in the 1 to 3 inch range over
the course of the two days, though local amounts could be higher
if heavier storms move over the same areas. Overall cloudiness
should help keep highs in check, with afternoon temps forecast in
the low to mid 80s.

By Wednesday, the lingering boundary will be almost completely
dissipated, but should still provide just enough of a focus to
fire off a decent number of showers and thunderstorms. Am carrying
high end chance pops for most locations based on this thinking,
but with lower QPF compared to the previous two days. Highs may
climb a couple degrees higher than Monday Tuesday, but should
still top out in the mid 80s.

Thursday looks like the quietest day with respect to convective
coverage. The old frontal boundary is expected to be completely
dissipated and the next system will still be too far removed to
have a significant impact on the local weather.

By Friday and Saturday, a plume of deep gulf moisture will begin
to move into the area, and will interact with a weak upper trough
moving through the middle mississippi valley. This should be
enough to fire off scattered showers and thunderstorms and am
carrying solid chance pops both days.

During the second half of the work week, temperatures look fairly
steady in the upper 60s and lower 70s for morning lows and in the
mid to upper 80s for afternoon highs.

Aviation
PrimarilyVFR conditions will prevail at the TAF sites through the
evening hours. A few showers and thunderstorms will be possible for
the next couple of hours or so in the vicinity of an outflow
boundary now pushing south of interstate 10. MVFR ceilings will
dominate after 06z Monday with some light fog possible at the more
fog prone TAF sites. Scattered to numerous convection is expected to
impact the terminals on Monday.

Marine
Light to occasionally moderate onshore flow will prevail across the
coastal waters through the upcoming week as a ridge of high pressure
remains over the eastern gulf of mexico and florida. A weak cold
front will approach the coastal waters Monday into Tuesday, but will
stall near the coast before dissipating by Wednesday.

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.
