Discussion
For the 08 18 17 1800 utc TAF package.

Aviation
Deep layer ridging prevails across the region today, which
should act to keep convection fairly isolated in nature. Already
seeing some shower activity along the coast and over east central
la. Maintained vcts all sites for the rest of the afternoon amid
an otherwiseVFR forecast with west winds under 12kt. Calm winds
and a clear sky expected tonight. Could see some light and brief
vsby restrictions toward morning, but will omit from forecasts at
this time owing to low confidence in temporal spatial details.

update... Minor westward expansion of low end pops across
the area for this afternoon. Otherwise all looks good.

Prev discussion... Issued 707 am cdt Fri aug 18 2017

for 12z TAF issuance.

Aviation...

not many changes to previous TAF thinking this morning. Seeing a
little bit of light fog this morning but that should burn off
shortly. OtherwiseVFR conditions should prevail through the
period. Hard to rule out at least widespread convection today
given the moist unstable airmass in place across the region and
lack of good capping per forecast soundings... Thus have retained
the inherited vcts mention all sites other than kbpt. Will let
later shifts better refine low cloud light fog threat for late
tonight.

area remains under a flat ridge along the northern gulf coast
today. Thus making for another tricky convective forecast. At this
time expect bulk of the convection will remain to the north of the
forecast area, however with moist unstable air will can not rule
out some activity along any outflow boundaries from the north.

This would mainly be during or shortly after peak heating and
along the northern and eastern portions of the forecast area.

Also inherited a heat advisory. This mornings guidance is not a
bullish on heat index values getting up to criteria, especially in
the potential convection and it appears to show drier air mixing
down at the other locations. However the past few days dewpoints
have stayed up a little more than expected and thus will continue
the heat advisory for now most areas. Did add tyler county and
removed the eastern fringe.

Otherwise the ridge weakens just a bit for the weekend and thus
will increase pops just a bit but not as high as the previous
forecast.

Then late weekend into early next week still see and inverted
trof moving across the gulf will cause an uptick in clouds and
showers early next week. This may hinder eclipse viewing for our
area especially along the coastal zone.

This trof will move inland around mid week, however daily rain
chances will continue.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data.

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.
