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



A weakening area of high pressure will maintain its influence over 

the region through this evening. As this dome of high pressure 

further weakens, a front will slowly approach from the north through

 tonight before stalling nearby on Friday. This frontal system

should  slowly lift northward as a warm front into southern New

England this  weekend. A stronger cold front may impact the waters

sometime early  next week.
