00z issuance... Storms across south central alabama and northwest
florida will begin to dwindle over the next 2 to 3 hours with the
loss of daytime heating. Light and variable winds expected overnight.

Expect much of the same on Friday afternoon with scattered showers
and storms across the area bringing frequent lightning and wind
gusts of 35 knots or greater. 07 mb

Prev discussion issued 552 pm cdt Thu jul 27 2017
discussion... See updated information for land areas below.

Update... Have updated to increase pops over much of the western
florida panhandle through the early evening hours, and also to
include small pops over much of southeast mississippi where a few
stray showers storms may occur. Made additional adjustments to
temperature trends early in the period. 29
prev discussion... Issued 410 pm cdt Thu jul 27 2017
near term now through Friday ... 27.12z upper air analysis shows
a deep layer ridge positioned from new mexico, eastward into the
mid-south. A weakness in the geo-potential height field is more
aligned over the southeast, where a weak trof cyclonic circulation
was generating cloud cover over the southeast us along the
georgia and southern south carolina coast. At the surface, weak
high pressure was analyzed over the central gulf coast. An
assessment of deep moisture has shown a continued lowering of pwat
values over the past 24 hrs with values now 1.4 to 1.7 inches
over the forecast area. Deepest moisture (pwat's 1.8 to 2.2 inches
resides over the northern florida peninsula closer to the trof
position.

Isolated to lower end scattered coverages of storms is expected
thru the remainder of the afternoon mainly along and east of the
tombigbee river. Drier conditions look to persist west of the
river which is dominated by the eastern nose of the deep layer
ridge better compressional sinking there. Considering instability,
latest mesoscale analysis shows surface based capes between 2000
to 4000 j kg and along with drier air aloft, the collapse of any
stronger afternoon thunderstorm cores will be efficient in
producing the potential of brief strong gusty surface winds up to
near 50 mph and frequent lightning. A very isolated severe storm
cannot be ruled out, with main threat in these be damaging winds
in excess of 60 mph.

Away from storms, latest observations show afternoon heat index
values on track and ranging from 102 to 107 degrees for many
areas. Review heat safety tips at the following link:

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.
