.SYNOPSIS FOR THE MIDDLE TEXAS COASTAL WATERS...
A cold front will move into the waters this evening and push

tonight into Friday morning as high pressure builds into the area
behind the cold front. Widespread showers are expected tonight
into Friday morning as moisture increases ahead of a strong upper
level disturbance. Rain chances are expected to diminish Friday
night as drier air moves into the region behind the front. An
upper disturbance and coastal trough will bring an increased
chance of showers and thunderstorms Saturday, subsiding on Sunday.
Mainly light to moderate winds are expected this weekend and
through the first half of next week, however moderate to strong
winds will be possible in deeper waters for a time Saturday night.
