A series of disturbances from the Ohio Valley will move along a
boundary near the Maryland/Pennsylvania border bringing periods of
showers and thunderstorms.  Moisture and cloudiness will continue
to increase from west to east throughout the day and showers
and thunderstorms will progress east-northeastward also.  Deep
moisture with 2.0+ PWs will bring the possibility of locally heavy
rainfall overnight into early Friday.  Forecasted basin avg rainfall
over the next 24 to 36 hours is expected to range from one quarter
/0.25/ inch across interior New York upwards to three /3.00/ inches
near the Maryland/Pennsylvania border into parts of northern
Virginia, Maryland, eastern PA and NJ.  Locally heavy rainfall
of 3 inches or more will be possible in spots, especially where
storms train across the same locations.

Based on the obersered rainfall through 12Z toiday and forecasted
rainfall over the next 48 to 72 hours, general main stem river
rises are expected to range from 1 to 4 feet.  However, very
sharp and more significant rises will be possible on smaller
streams and creeks in the vicinity of heavy downpours.  All MARFC
river and stream forecasts will be issued before 10:30am.
