.DISCUSSION...
Weather map shows moderate pressure gradient over the NW Gulf as
high pressure builds eastward across the eastern Gulf. Low
pressure trof axis aloft over SE Texas/Louisiana coast this
morning. The trof axis is providing focus for numerous showers &
isolated thunderstorms (not a lot of lightning strikes so far with
this activity) over the coastal waters, gradually moving inland
across S Louisiana.

The best chances for showers and thunderstorms will remain over
the coastal waters into lower Acadiana thru sunrise, and spread
inland later this morning into the afternoon hours. HRRR guidance
mostly in agreement but lagging a couple of hours behind. Like
the last few days, chances will diminish by evening with the loss
of daytime heating.

For Thursday, expecting less coverage over the coastal waters,
with the focus further inland and later in the late morning/early
afternoon hours as the upper level trof fills and drifts northward
with the sea breeze the primary focus for convection.

For the remainder of the forecast period, mainly sea-breeze late
morning and afternoon showers and thunderstorms, with possibly
better chances for the weekend. Temperatures near normal.

.MARINE...
SW winds ~15 kts early this morning will diminish to 10-15 kts
later today and become more south to southeast for the remainder
of the period as high pressure becomes re-established over the
northern Gulf of Mexico. Scattered to numerous showers and
thunderstorms will continue today as low pressure aloft remains
over the northwest Gulf of Mexico. Shower and thunderstorm chances
expected to gradually diminish later this week into the weekend.
