.SYNOPSIS FOR THE TIDAL POTOMAC AND MD PORTION OF THE CHESAPEAKE BAY...

High pressure will wedge into the region for the end of the week,
then move offshore over the weekend. Small Craft Advisories will
likely be needed for portions of the waters both Friday and Saturday
 afternoons. Extensions may be needed due to southerly channeling
Sunday into early next week. Next substantial front to cross the
waters looks to arrive by Tuesday bringing renewed chances for
showers and thunderstorms.
