.SYNOPSIS FOR THE MIDDLE TEXAS COASTAL WATERS...

Small Craft Advisory conditions are expected to continue across 
the nearshore waters through midnight and the offshore waters 
through mid morning Wednesday, mostly due to seas. A weak to 
moderate offshore flow early Wednesday morning will become light 
from the east and southeast by Wednesday afternoon. A weak to 
moderate northerly flow redevelops Wednesday night due to another 
cold front. Moderate to strong northeast flow will return Thursday
in the wake of our next front with a chance for cold rain 
Thursday and Thursday Night. Winds will weaken and shift back to 
the southeast Friday afternoon as temperatures warm back into the 
70s. Just as fast as the winds weaken, they will pick back up with
strong southerly flow expected to develop this weekend which 
could lead to our next Small Craft Advisory period.
