.SYNOPSIS FOR THE MIDDLE TEXAS COASTAL WATERS...
A cold front pushing through South Texas this afternoon will
continue moving into the coastal waters this evening. The front is
expected to stall over the offshore waters by Thursday morning and
remain nearly stationary through the day. The front is expected to
move back toward the coast Thursday night. Scattered to numerous
showers and isolated thunderstorms will be possible tonight, with
isolated to scattered showers expected Thursday into Thursday

with southeast flow developing and continuing on Saturday. Another
cold front is expected to push across area waters for the second
half of the weekend.
