12z TAF discussion:
lifr category stratus has managed to expand from the pine belt
region up into the jan hks-gtr area. Expect this to remain for the
next few hours until heating helps to mix and break up ceilings.

It does seem fog is not as much of a concern this morning with
surface winds picking up just a bit. Otherwise, a significant
concern this forecast period will be late morning aftn scattered
to numerous shra tsra, which still look most likely for
southern eastern sites. Ec

Discussion
Today through tonight...

a heat advisory was necessary again for today over the arklamiss
delta region where heat indices are expected to peak just above
the advisory threshold. Otherwise, the subtropical ridge will
begin breaking down today and tonight as westerlies begin to
shift southward. This should mean that today's heat advisory will
be the last for a while, and that we will see increased diurnally
driven convective rainfall, especially for locations along south
of the i-20 corridor where precipitable water is expected to
increase to above two inches. With the slightly cooler mid level
air, vertical totals (near 25) are forecast to be a little more
conducive to stronger microburst potential this afternoon. Expect
storms to diminish this evening, although outflow from a
convective system to our north could move far enough south to
maintain the storm threat going well into the evening for
locations along north of the highway 82 corridor. Otherwise,
mostly quiet conditions can be expected for the overnight. Ec
Thursday through Tuesday night... A very wet extended period is
setting up for the arklamiss. Deep southerly moist flow will
increase moisture across the area on Thursday, with pwats climbing
above 2.0 inches over most of the area. Scattered to numerous
showers and thunderstorms are likely on Thursday with high
temperatures around 90 degrees. Little will change on Friday with
abundant moisture expect another round of showers and storms. Upper
troughing will move in over the weekend and this combined with pwats
above 2.0 inches, will make for a daily dose of scattered to
numerous showers and storms each day. This pattern will continue
into Monday before the upper trough finally shifts to the east, as
upper ridging and drier conditions build in Tuesday. With all of the
clouds and convection high temperatures will be below normal,
ranging from the upper 80s to lows 90s through the weekend. 15

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
