Update
Updated for 12z aviation discussion

Aviation
12z TAF discussion:
winds have diminished consideraby since last evening, but will
pick up again by mid morning with sustained 10 to 15 knots and
gusts near 25 knots. By sunset, the wind will diminish and
gradually become calm.VFR conditions will prevail through the
period. 26

Discussion
Today and tonight: last bit of cloud cover has just about moved out
of the forecast area as of 19 09z. Despite the dry air and efficient
radiative heat loss, tight pressure gradient has been sufficient to
keep winds up overnight. Expect winds to strengthen once again by
mid morning as mixing layer deepens. Sustained winds of 10 to 20 mph
with gusts to around 25 mph should be common, especially over the
open areas of the arklamiss delta region.

Surface ridge axis will become situated over northern portions
tonight with lessening gradient to the south. Thus, expect boundary
layer decoupling and a rapid fall off of temperatures during the
evening as winds diminish. With the dry air supporting optimum
radiational cooling, lows from the mid 20s in the northeast to the
mid 30s south look attainable. 26
Monday through Saturday night: looks like a dry and cool extended
period for the arklamiss. The surface high will slowly begin to
shift to the east on Monday with the surface flow becoming more
southerly by the late afternoon hours. Temperatures will continue
to be on the cool side, with highs in the mid 50s to around 60
degrees across the area. Temperatures Monday night will not be
quite as cold, but will still fall into the 30s.

With southerly flow and high pressure continuing, Tuesday will be a
nice day with highs in the mid upper 60s. A deep upper trough and
associated dry cold front will move across the area Tuesday night
with cooler temps returning for Wednesday. The global models are in
pretty good agreement of a cut-off low developing over the northern
gulf on Wednesday into thanksgiving day, but this feature will be
well southeast of the area. Turkey day looks like it will be dry and
cool, with highs in the mid upper 50s. The dry conditions will
continue through the end of the week with highs in the low mid 60s
on Friday, and into the upper 60s on Saturday, before another dry
cold front swings across the area Saturday night. 15

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.
