Update
Another muggy night on tap... Sounds like a broke record but we
are in that period of time. The 30 year climo though does give
some hope that things will be changing as we have passed our peak
in summer heating... Again looking at the 30 year climo records.

But this is a slow process and will require another three to four
weeks till we notice any real change.

For now IR stlt images are picking up an upper level sys over
south florida this eve. Guidance is suggesting that it will drift
acrs the central gulf and will bring increasing clouds and showers
by midweek.

For the weekend... Hot and humid with scattered afternoon showers
and a few thunderstorms... Typical SE tx and SRN la weather.

Reminder that the heat index will soar above the century mark
tomorrow. Just keep yourself hydrated and take breaks as needed...

sunscreen and a good hat are always smart choices. Forecast looks
fine at this time.

Prev discussion issued 639 pm cdt Fri aug 18 2017
discussion...

19 00z TAF issuance.

Aviation...

just a few small shra tsra seen on radar late this aftn, well away
from TAF locations. This activity should dissipate within the next
hour or two with mostly clear skiesVFR to persist overnight. Some
brief patchy fog or low clouds will be possible early Saturday
morning but expect conditions to be fairly transient at this time.

Otherwise, conditions Saturday will be similar to the past few
days withVFR prevailing amid a daytime CU field based around
3500-5000 ft. Some isolated to widely sctd aftn sh or TS will be
possible, with west to southwest winds less than 10 kt.

prev discussion... Issued 329 pm cdt Fri aug 18 2017
discussion... Limited showers shown on radar early this afternoon
along a weak seabreeze just inland of the coast, and
additionally a few over central louisiana. Surface observations
showing temperatures generally in a 90-95 range with dewpoints in
the mid 70s. Apparent temperatures not running quite as high as
yesterday and holding just under local heat advisory criteria.

Latest guidance suggesting similar numbers for Saturday and thus
will not introduce an advisory for the beginning of the weekend.

Limited changes to forecast. Will see a continuation of a typical
late august weather pattern. Hot and humid days can be expected
followed by warm and muggy nights. High pressure aloft currently
over the region and suppressing any significant convection today
will weaken moving through the weekend. This as an easterly wave
now over florida advances over the southeast CONUS and adjacent
gulf waters. A gradual uptick in pops then expected going into
the new work-week.

Marine... Surface high pressure over the northwest gulf will
maintain a light and somewhat variable flow through the weekend.

Winds will trend east to southeast and remain light moving into
the new work-week as high pressure becomes oriented across the
southeast CONUS and adjacent coastal waters.

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.
