Aviation
MVFR ceilings are beginning to develop along the coast and will
continue to push inland over the next few hours. The main question
during the overnight hours whether how far south and east
thunderstorms will be able to progress. Kaex is the most likely
to see thunderstorms during the overnight hours. However, there
appears to be enough potential for thunderstorms to move southward
that vcts were included at all TAF sites during the most likely
time frames. Any thunder MVFR ceilings are expected to clear out
of the area during the 10z-14z time range and will give way toVFR
conditions for the rest of the day.

discussion...

currently watching two areas of convection on regional 88ds. First
area is noted passing to our north... High res guidance has had a
good handle on this activity and continues to prog it staying to
our north. Second area upstream moving out of cntl tx and into
e-cntl sern tx at the moment... This activity will bear watching as
current trajectories would carry into our nwrn zones during the
overnight hours, although high res guidance is not in agreement on
an eventual solution. Klch 00z sounding indicated a little
capping around 850 millibars which if translated forward into the
overnight hours could help spell an end to the action as it
approaches. Inherited grids zones showed chance neighborhood pops
for the nwrn zones overnight which still looks good. Elsewhere,
inherited grids zones look fine... Long story short, no evening
update is planned at this time.

prev discussion... Issued 237 pm cdt Wed jun 19 2019
discussion... High pressure aloft is centered over the west gulf
this afternoon with ridging stretched into the northwest gulf
coast. An upper disturbance is pushing into the texas panhandle
and this will spark storms later this afternoon and evening across
north texas.

At the surface the bermuda high will remain centered in the
central atlantic and into the north gulf coast. This feature will
remain in place through the period which will keep a warm and
moist south flow in place.

Tonight storms are expected to push across northeast texas and
into louisiana, however the upper ridge is expected to remain in
place as well. This will prompt storms to weaken as they move
into the local area, however enough instability and lift will be
in place that some storms may be still be strong through the lakes
and cenla. The line of showers and storms is expected to decay
through early Thursday much like this morning with the showers and
storms along the old outflow boundary.

The upper ridge is expected to become more established by Friday
and into Saturday before breaking down Sunday. Low to nonexistent
rain chances are expected Friday and Saturday. Heat index values
will also run from 102 to 107 Thursday through Saturday with a few
spotty areas maybe reaching up to 108 for an hour or two well
inland.

Marine... A light to moderate onshore flow is expected through
early Friday, however the pressure gradient is expected to tighten
between the atlantic ridge and a developing area of low pressure
over the plains this weekend. This is expected to cause winds to
increase into the 15 to 20 kt range Saturday and perhaps briefly
hit SCA criteria on the western zones.

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.
