SHORT TERM (Tonight through Thursday Night).

Rain associated with the strong low level warm advection has moved into the coastal waters this afternoon. The mid level short wave trough will be moving through the coastal region this evening. Could see showers linger over this area before drying arrives once the short wave trough departs to the east. High boundary layer moisture will reside over much of the region tonight as the dry air aloft moves in. Expect low stratus and fog to cover most of the inland areas during the overnight hours into the early morning Thursday. The frontal boundary will push into the coastal waters by late Thursday morning with northwest to north winds occurring in the wake of the front. Not much in the way of cooling as downslope flow will lead to warming on Thursday. It will be cool and dry for Thursday night as a high pressure ridge builds into the region.

Tide levels continue to be around 1.5 feet above expected with tides going above 2 feet MSL at Bob Hall Pier in the past hour. Will continue the Coastal Flood Advisory through 03Z tonight.

LONG TERM (Friday through Tuesday).

The extended period begins with high pressure moving east of the region, resuming onshore flow and moisture advection. The next in our series of disturbances in progressive flow is forecast to move through Saturday, increasing rain chances Saturday and Saturday night. Models look to favor locations close to the coast with some weak coastal enhancement over the weekend. By Sunday night high pressure will dry us back out, only for return flow to resume by late Monday out ahead of yet another system for the middle of next week.

Temperatures will remain mild through the extended period, with arctic air remaining well to the north.

MARINE.

Moderate to strong onshore flow will continue this evening across the Gulf waters. The flow will decrease to weak to moderate levels by Thursday morning as a frontal boundary moves into south Texas. Kept the SCA expiration at 07Z for the near shore waters, but winds and seas will remain elevated through the night over the offshore waters. Extended the SCA until 14Z Thursday for the offshore waters. Scattered showers will diminish during the overnight hours as the upper level disturbance moves to the east. A front will move through the coastal waters late Thursday morning with a moderate offshore flow/SCEC conditions occurring Thursday night mainly over the offshore waters.

A moderate northeast flow early Friday will turn onshore by Friday evening, then continuing onshore through Saturday night. A weak coastal trough may develop later in the weekend, lifting out of the area later Sunday and Sunday night. Onshore flow then resumes on Monday and becomes moderate on Tuesday as low pressure strengthens over the southern plains.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
