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

High pressure over the Carolinas will drift offshore through Saturday as low pressure moves from the Upper Great Lakes to northern New England. The area of low pressure will send a trailing cold front southward into the Mid-Atlantic Saturday night into Sunday. The front will drop further south the first half of next week, likely reaching as far south as Florida by Tuesday night as strong high pressure builds in from the Northeast. Small Craft Advisories may be needed Saturday in west to southwest flow ahead of the cold front, then in northeast to east flow Monday behind it.
