Scattered to numerous strong rainshowers cover the areas from the western sections of Louisiana, to the coastal plains and the coastal waters of Texas and NE Mexico. High pressure will remain across the region through Monday. A weak cold front will enter the far NW Gulf this weekend, accompanied by scattered showers and thunderstorms. A trough will develop each night in the Yucatan Peninsula, and support pulses of fresh to locally strong winds in the south central Gulf of Mexico at night and into the morning.
