Aviation
12z TAF discussion:
a cold front will move southeast across the area today. In advance
of the front, MVFR ceilings and isolated showers will develop this
morning, but skies will becomeVFR by noon. Isolated thunderstorms
will be possible this afternoon and early evening between hbg and
pib. As the front passes each TAF site, winds will switch from the
southwest to the north at 10 to 15 knots with higher gusts. Ceilings
will lower to MVFR with isolated showers continuing through the
end of the period. 26

Discussion
Today and tonight: the forecast area remains in the warm sector this
morning with a stalled frontal boundary just to the northwest. To
the north of the front, areas of showers and a few thunderstorms
continue as moist mid level southwest flow is lifted overtop the
cool airmass in the lower levels.

Meanwhile well to the north, a mid level trough moving through the
plains and upper ms valley looks to help nudge the local frontal
boundary southeastward today. The boundary will begin moving into
northwest portions by mid to late morning with mostly light showers
breaking out along and ahead of it. Capping inversion just above the
boundary layer should keep convection shallow, at least until it
moves into southeast portions later this afternoon. In those areas,
a weaker cap and better instability will allow for deeper
convection, especially over the far southeast where mlcapes
approaching 1500 j kg and 30 knots of deep layer shear may help
produce a few strong storms.

The deeper convection will continue into the evening a bit, but
diminish with the frontal passage. Light showers will, however,
continue as isentropic ascent continues aloft. 26
Tuesday through Sunday: a rather weak cold front will be in the
process of dropping south through southern portions of the
forecast area, as day breaks on the period Tuesday. A cool drier
airmass at the surface will be advecting into the region during
the course of the day, in the front's wake. However aloft,
continued moist southwest flow will persist. This will result in
ongoing cloud cover across the region, with good chances for rain
throughout Tuesday afternoon. Temperatures meanwhile will range
from the mid 50s in the delta behind the front, to the upper 70s
along and just ahead of the front.

Although clouds currently look to linger much of the day Wednesday,
rain chances will come to an end during the morning hours. High
pressure though will continue to settle over the region, where
noticeably cooler drier conditions will exist. Highs Wednesday
afternoon will range from the lower 60s to middle 70s, and lows
Wednesday night will range from the upper 40s north to middle 50s
south.

High pressure at the surface shifts east of the CWA Thursday through
Friday, gradually causing winds to come back around from the south.

Conditions will begin to warm during this time, with more breaks in
the clouds being observed as well. However, this will all be brief
as a broad trough aloft swings southeast into and through the region
late Friday and through the weekend. Currently, this is progged to
send yet another cold front south into and through the cwa. As a
result, rain chances begin increasing late Friday through Saturday,
while coming to an end early Sunday morning. 19

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.
