Brief high pressure will return to the waters today with a warm front set to cross late tonight into Wednesday morning. A cold front will cross the waters Wednesday into Thursday with an area of low pressure passing to the south Thursday night into early Friday. High pressure returns for the weekend with a stronger front early next week. Additional Small Craft Advisories may be needed at times for portions of the waters during this period.
