.DISCUSSION...
For 12z TAF issuance.

.AVIATION...
Local 88Ds already show the beginnings of today`s convection
firing up over the coastal waters and the swrn zones thanks to an
apparent shear axis over the nrn Gulf. Expect this activity to
spread farther inland and expand with daytime heating...still
looking at best coverage across the ern terminals. Otherwise VFR
conditions will prevail through the period for the most
part...currently seeing some low clouds across cntl LA which could
persist next couple of hours.

.PREV DISCUSSION... /issued 303 AM CDT Wed Aug 16 2017/

DISCUSSION...The sub-tropical ridge remains stretched from the
Atlantic into the northern gulf coast this morning which is
keeping the warm south fetch in place. Aloft the region is between
a ridge over Texas and a ridge over Florida. An upper low is over
the central gulf.

With no ridge in place aloft, the area under the northern edge of
an upper low, and a hot and humid air mass in place another day
of showers and storms can be expected. Temperatures will be near
climo values.

Beyond today weak ridging aloft is expected to build over the
area. This will decrease rain chances a bit, however scattered
afternoon storms are still expected through the weekend.
High temperatures may rise a degree or two with the slight
decrease in pops, however remain below heat adv criteria.

MARINE...Isolated to scattered thunderstorms are expected through
the period, however the winds are expected to remain light and
onshore outside of storms.
