Except for a small area of showers and thunderstorms across
parts of the lower James and Appomattox river basin Thursday
afternoon and evening,dry weather prevailed across the rest
of the Mid Atlantic region.

High pressure will continue fair and dry weather today into
much of Saturday.  There could be a passing shower or
thunderstorm across our far western river basins Saturday
afternoon/evening.

Dewpoints and PW`s will be on the increase this weekend and
with the arrival of a weak cold front will come the likelihood
of showers and thunderstorms Sunday.

72 hour basin average QPF is forecast to range from a tenth
/0.10/ to one half /0.50/ inch.  However, with PWAT`s rising to
1.50 to 2.00 inches expect locally heavy downpours.  While main
stem river response is expected to be minor (2 feet or less)
sharper rises will be possible on smaller streams and creeks in
the vicinity of heavy downpours.

MARFC river and stream forecasts will be issued before 11am.
