A 1030 mb high pressure is centered over Arkansas near 35N91W producing 10-20 kt NE to E winds over the Gulf of Mexico. The cold front over the SW Gulf waters will dissipate tonight. Fresh to strong N to NE winds will prevail over the eastern Gulf through Thu. The next cold front will move into the NW Gulf Sun followed by fresh to strong NE winds and building seas.
