A secondary, reinforcing cold front will then quickly push E to NE across the region early today. A high pressure ridge will pass quickly E across the area later today and tonight. Another strengthening cold front will move across the N portions Wed, clearing E of the waters Wed night, and followed by a series of low pressure troughs or weak cold fronts Thu and Thu night. Another cold front will approach from the N Fri, move into the N portions Fri night, then continue S across the remainder of the waters Sat and Sat night. High pressure will build over the S waters later today and tonight, then shift E Wed. High pressure will rebuild across the S waters Thu into Sat, then shift S and dissipate ahead of the passing cold front. High pressure will build offshore across the S waters following the cold front Sat night.
