A much colder air mass will continue to move south today through
most of the upcoming week, with strong and gusty northerly winds
to continue. Small Craft Advisories in effect for all coastal
waters through Midnight, with a Gale Warning issued thereafter
through Midnight Tuesday night for the 0-60 nautical mile marine
zones. A surface low is expected to develop today across the
