Synopsis: High pressure centered in the Gulf of Mexico will slowly lift northeastward today, allowing a reinforcing cold front to sweep across the Keys waters this afternoon and evening. High pressure will then strengthen on Wednesday as it moves by to our north through the Southeast U.S.. High pressure will reach the western Atlantic on Thursday night, then stretch out into an east west ridge axis over the Florida Peninsula Thursday night through Friday night, before weakening this weekend.
