A broad surface high centered over the Tennessee Valley encompasses

southward, becoming centered across the northern Gulf Coast Sunday.
Local winds will respond to this by weakening and becoming more
onshore. Weaker winds will persist throughout the remainder of the
forecast period as that ridge remains nearby.
