.Synopsis for Massachusetts and Rhode Island coastal waters...
A cold front approaches today bringing a period of small craft
southerly wind gusts out ahead of it. Brief sfc ridging early Sun
gives way to low pressure that will track near or just S of the
coastal waters later Sun into Sun night. This low will continue to
intensify Mon as it lifts north through the Canadian Maritimes. This
will result in an arctic airmass moving across the waters in the Mon
through Wed time frame. Areas of moderate freezing spray are also
expected over some of our waters too.
