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

High pressure will remain nearby through tonight. 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.
