.SYNOPSIS FOR THE TIDAL POTOMAC AND MD PORTION OF THE CHESAPEAKE BAY...
A stationary frontal boundary will remain off to the south near the
Virginia-North Carolina border into Thursday. This system returns
northward as a warm front by Friday which increases thunderstorm
chances. High pressure builds across the northeastern U.S on
Saturday before another frontal system approaches from the west on
Sunday into early next week. Small Craft Advisories may be needed on
Sunday evening into the night due to southerly channeling.
