Synopsis: High pressure centered over our region will slowly shift southeastward on Wednesday and will gradually weaken as weak low pressure moves across Deep South Texas. Southerly winds will strengthen on Thursday evening in advance of a cold front that will be progressing eastward across the southeastern states. Showers and a few embedded thunderstorms will reach our waters on Friday, with activity decreasing on Friday night as the front crosses our region. Onshore winds will briefly strengthen in the wake of this front by late Friday night and Saturday morning as high pressure builds into the southeastern states, with winds and seas diminishing by Saturday night as high pressure weakens just north of our waters.
