A cold front will move off the east coast today as
high pressure briefly returns to the Mid Atlantic
region.  Low pressure will pass North and West of
our hydrologic service area Tuesday.  The associated
warm front and eventual cold front will bring a
wintry mix of snow, sleet, freezing rain and rain
to the Mid Atlantic.  A cold front will begin to
push across New York state early Wednesday then
creep southward into Virginia before stalling out
across the Mid Atlantic.  Waves of low pressure
will ripple east-northeast along this stalled out
boundary and bring more rain and rain changing
to sleet and snow to the Mid Atlantic region
Wednesday, Wednesday night into early Thursday.

72 hour basin average QPF (water equivalents) are
expected to range from four tenths /0.40/ of an
inch to just under one and one half /1.50/ inches.
The combination of expected precipitation and
some snowmelt will produce several foot rises
throughout our Virginia river basins into parts
of the Potomac.  Please refer to MARFC`s river
and stream forecasts for the latest stage and
forecast information.

Ice effects continue across rivers and Streams,
especially across New York, Pennsylvania into New
Jersey.  Abrupt fluctuations of several feet are
quite possible.

All MARFC guidance will be issued before 11am.  If
any WFO`s have any questions or concerns, just call
MARFC.
