A warm front should emerge off of the central waters today under overall weak, broad high pressure. The warm front will move N tonight while a cold front approaches from the NW. The cold front should sweep quickly E over the N waters by Sun afternoon and through the S waters overnight Sun and into Mon. While high pressure will then build over the S waters, around persistent, broad low pressure over SE Canada, another series of surface troughs will pass from NW to SE over the N waters Mon through Tue night. High pressure then gradually builds E over most of the waters Wed and Wed night. However, a surface front may develop off of the Carolina coast late Tue night with weak low pressure possibly moving E along the front and off of the coast Wed night.
