.SYNOPSIS FOR THE MIDDLE TEXAS COASTAL WATERS...
A coastal trough will be over the Gulf waters today through this
evening, then gradually weaken by Saturday morning. A moderate
flow is expected over the offshore waters closer to the trough.
The flow may briefly increase to moderate to strong levels over
the offshore waters north of Port Aransas tonight. Scattered to
numerous showers along with isolated to scattered thunderstorms
today through tonight. Rain chances are expected to decrease on
Saturday. Patchy to areas of sea fog are expected across the bays
and near shore waters late tonight into Saturday morning. Weak
to moderate onshore flow will occur Sunday ahead of the next cold
front. This front will move through the Middle Texas Coastal
Waters Sunday night into Monday morning. This will result in a
chance for showers and isolated thunderstorms ahead of the
boundary, and a moderate offshore flow in the wake of the front on
Monday. The offshore flow will diminish Monday night, as high
pressure builds into Texas. Onshore flow will resume on Tuesday as
the high moves east.
