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

High pressure will move offshore today as a cold front approaches
from the Great Lakes and Upper Midwest. The cold front will cross
the region tonight as low pressure develops over northern Florida. A
 secondary cold front will surge southward from the eastern Great
Lakes and northeastern U.S. Friday night into Saturday as high
pressure builds to the north and low pressure meanders off the
Carolinas. Small Craft Advisories will likely be needed Friday night
 through the weekend. A Gale Warning may be needed for portions of
the waters late Friday night into Saturday, and possibly Sunday.
