This is due to surface high pressure building westward across the Gulf of Mexico, but still interacting with lower pressure inland. The pressure gradient will weaken further across the western Gulf of Mexico Friday, with light to moderate southeast winds and low seas prevailing across the Lower Texas Coast for the remainder of the period.
