.SYNOPSIS FOR THE MIDDLE TEXAS COASTAL WATERS...

Gentle to moderate (BF 3-4) onshore flow with occasionally fresh
(BF 5) breezes along the southern bays and nearshore waters will
continue through most of the upcoming week. Rain chances will
become low to medium (20-70%) late today through early Tuesday

waters. The boundary passage will shift winds to the north and
bring in drier air. Onshore flow will return by Wednesday.
