.SYNOPSIS FOR THE TIDAL POTOMAC AND MD PORTION OF THE CHESAPEAKE BAY...
A SURFACE TROUGH WILL LINGER WEST OF THE WATERS NEAR THE BLUE RIDGE

OF SHOWERS AND THUNDERSTORMS. A COLD FRONT BRINGS POTENTIAL FOR
MORE WIDESPREAD STRONG THUNDERSTORMS FRIDAY INTO FRIDAY NIGHT.
SMALL CRAFT ADVISORIES MAY BE NEEDED IN THE WAKE OF THE FRONT
FRIDAY NIGHT INTO SATURDAY MORNING. HIGH PRESSURE LOOKS TO RETURN
FOR AT LEAST THE FIRST HALF OF THIS WEEKEND RESULTING IN LOWER RAIN
