.SYNOPSIS FOR THE TIDAL POTOMAC AND MD PORTION OF THE CHESAPEAKE BAY...
HIGH PRESSURE WILL MOVE FURTHER OFFSHORE TODAY AS A WARM FRONT LIFTS
AWAY FROM THE REGION. A SURFACE TROUGH WILL LINGER WEST OF THE
WATERS NEAR THE BLUE RIDGE MOUNTAINS THIS AFTERNOON BEFORE DRIFTING
SOUTHEASTWARD ACROSS THE WATERS TONIGHT INTO THURSDAY. THIS TROUGH
MAY IGNITE MULTIPLE ROUNDS 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 CHANCES BEFORE ANOTHER FRONTAL SYSTEM
APPROACHES EARLY NEXT WEEK. SMALL CRAFT ADVISORIES MAY BE NEEDED IN
SOUTHERLY CHANNELING SUNDAY, THOUGH THERE IS UNCERTAINTY IN THE
TIMING OF THE ARRIVAL OF THE NEXT FRONT.
