the waters Sat night and Sun. High pressure will build SE across

the waters later Sun into Mon, then shift SE Mon night. A cold

front will clip the eastern portions late Mon night. Weak low

pressure developing inland over the Mid-Atlantic on Tue will

slowly push a warm front NE across the waters Tue night through
