 across the northern Gulf into the coastal waters through the weekend
 into early next week providing light to modest southeast winds. Low
 to modest seas will accompany the southerly wind field. An upper
 level ridge will keep shower activity limited at best into the first
 half of the weekend. Rain chances will increase late in the weekend
 into early next week as a trough moves into the coastal waters.
