Discussion
Note aviation discussion below corresponding to the 12z tafs.

Aviation
A mixture of MVFR andVFR conditions early this morning will
transition to predominateVFR by afternoon. MVFR conditions will
develop after 06z Friday. Weak onshore flow early this morning
will become moderate breezy this afternoon early evening. Weak
s SE wind near the end of the TAF period.

Prev discussion issued 423 am cdt Thu jul 18 2019
short term (today through Friday)...

no change to the semi-permanent upper pattern (ridge over the srn
conus with disturbances moving around the NRN periphery of the
ridge) during the period (gfs ECMWF nam deterministic output). Nam
and GFS deterministic runs maintain pwat values below normal
during the period. No significant pcpn expected. Expect maximum
heat index values in the 105-109f range with isolated amounts
around 110f over SRN sections.

Long term (Friday night through Wednesday)...

the 500mb sub-tropical ridge will remain in place through Saturday
before starting to break down and shift northwest late this weekend.

Above normal temperatures and generally dry conditions are expected
through the weekend as limited moisture and subsidence continues.

However, can not rule out an isolated shower or thunderstorm with
the afternoon sea breeze. Breezy conditions will be possible
Saturday afternoon as broad high pressure across the gulf of mexico
and lower pressure upstream persist. The latest GFS and ecmwf
continue to suggest a weak cold front will move south into central
texas early next week before stalling across south texas by mid to
late week. There remains some uncertainty on how far south this
frontal boundary will make it. However, rain chances should begin to
increase across the CWA by early next week. Southeast winds are
expected to shift to the east with slightly cooler temperatures
on Tuesday and Wednesday.

Marine...

anticipate small craft exercise caution conditions over the srn
bays nearshore coastal waters this afternoon owing to the expected
thermal mslp gradient. Application of local expert system
suggests a moderate risk of rip currents today Friday. Small craft
exercise caution conditions are possible Friday night into
Saturday, mainly for the southern waters. Otherwise, weak to
moderate onshore flow will prevail with seas 2 to 4 feet. Isolated
to scattered thunderstorms over the waters Sunday through
Tuesday.

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.
