.SYNOPSIS FOR THE MIDDLE TEXAS COASTAL WATERS...

 

Winds will increase to moderate to fresh (BF 4-5) levels today and persist through Sunday ahead of and behind our next cold front.

 

Brief instances of gusts to strong (BF 6) levels can be expected Saturday afternoon and evening during the height of the frontal passage.

 

The increase of wind coupled with wave heights between 4-7 feet will likely lead to the issuance of a Small Craft Advisory closer to time.

 

Precipitation is also anticipated with this front, with medium to high (50-70%) chances over area waters through the day Saturday.

 

Winds will be more northerly post-front before returning to an onshore direction with gentle to moderate (BF 3-4) conditions by the start of next week.

 

Patchy to areas of fog can be expected through Friday morning with more limited chances late tonight into Saturday as cloud cover and precipitation increase ahead of the front.
