.SYNOPSIS FOR THE MIDDLE TEXAS COASTAL WATERS...
A generally gentle to moderate (BF 3-4) onshore flow will persist across the coastal waters through late in the week.
A cold front Sunday morning will result in winds being more out of the northeast at a strong to near-gale strength (BF 6-7) with seas increasing to 5-7 ft by Monday morning.
Aside from some streamer showers today (10-20% chance of rain), the next best chance comes with the cold front though confidence is low on exact chances.
