Sat night. The cold front will reach the S portion Sun, then
clear S of the area Sun night. Another low pressure will approach
the N waters late Sun, then move E and SE over the northern and
central portions Sun night into early Mon. Another cold front
will approach the N waters Mon, cross into the region Mon night,
then dissipate over the central area Tue. High pressure will
