.DISCUSSION...
Patchy fog has begun to settle in across portions of the area this
morning with a couple of streamer showers right along the coast.
Expect another round of showers and isolated thunderstorms today,
particularly right along the seabreeze this afternoon. Coverage
should generally be a touch lower than yesterday as available moisture
is slightly lower. Inverted V soundings suggest that gusty winds
will be possible with any stronger cells that are able to develop
this afternoon. Shower and thunderstorm activity should quickly
taper off after sunset with the loss of heating.

Wednesday should see even less coverage of showers and storms and
warmer temperatures as upper ridging to the west tries to nudge
closer. For the latter half of the week we end up sandwiched
between upper ridging over West Texas and an upper trof over the
north central Gulf. Most of the rainfall should remain off to the
east over the central Gulf Coast states, but we can`t rule out
some shower and thunderstorm activity over the eastern portions of
our area depending where the upper low is positioned. Upper
ridging nudges closer from the west to start out next week,
helping dry things out a bit to close out the forecast period.

.MARINE...
Surface analysis at 08Z shows a rather weak pressure gradient across
the NW Gulf, but enough of one to maintain onshore winds. The
pressure gradient may tighten some on Wednesday but then relax
through the end of the week. This means light to moderate winds will
continue and support generally low seas through Saturday.

At this time, forecast models are keeping any type of tropical
cyclone formation over the eastern Gulf for the weekend. We will
continue to monitor forecast data and updates from NHC, but most
likely if there are any impacts it will be higher seas.
