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

High pressure will build in from the Tennessee River Valley through
the middle of the week. A reinforcing cold front will cross the Mid-
Atlantic Thursday afternoon and evening. Low pressure will likely
track offshore of the Carolinas into the Atlantic Ocean Friday into
Saturday, but there is considerable uncertainty as to how far north
the low and its associated precipitation gets. A couple of clipper-
like systems may affect the area heading into early next week. Small
 Craft Advisories will likely be needed Thursday afternoon through
Thursday night.
