.SYNOPSIS FOR THE MIDDLE TEXAS COASTAL WATERS...
Scattered to numerous showers with scattered thunderstorms will
be possible tonight through Monday night as an area of low
pressure gradually moves over the waters, then inland by Sunday
night. Weak to moderate onshore flow is expected to persist
through the period, though brief Small Craft Advisory conditions
are possible as areas of thunderstorms move across the waters
tonight through Monday night. Flow will generally be southeasterly
but may become more variable for the second half of the week.
Isolated to scattered showers and thunderstorms will be possible
each day across the offshore waters in response to multiple mid-
level disturbances.
