The front will continue moving SE across the basin. In the wake of the front, strong northerly winds are expected in the western half of the basin, with gale force winds expected west of 95W on this morning. A secondary frontal boundary will drop southward to the northern Gulf early on Fri and reach the far southwestern Gulf by Fri evening. Strong high pressure will build in behind this front.
