...Unsettled weather likely across the Pacific Northwest into early next
week including heavy mountain snow and lower elevation rain...

...A strong cold front may produce brief bursts of snow under blustery
conditions later today across the interior Northeast...

The Pacific Northwest has entered a period of unsettled weather as
multiple systems from the Pacific are forecast to direct moisture toward
the region.  Precipitation across western Washington will be the heaviest
and most sustained through the next couple of days.  In addition, heavy
wet snow is expected to accumulate in the Washington Cascades.  Heavy rain
falling across the lower elevations may cause flooding concerns across
portions of western Washington and Oregon on Monday into early Tuesday
when the precipitation is expected to be the heaviest.  The associated
moisture will spread farther inland to bring light to moderate snowfall
across the northern Rockies.  Winds are expected increase especially near
the Washington coast and on the lee side of the Rockies where very gusty
downslope winds are forecast to develop.

Across the South, an upper level disturbance will support generally light
precipitation today from the Deep South to the southern Appalachians and
through the southern Mid Atlantic.  The rain should be exiting the
southeast U.S. coast Sunday night as the associated cold front begins to
slide more quickly offshore.

Across the Great Lakes and interior Northeast, a strong arctic front will
move across the region this afternoon into the evening.  Snow squalls are
expected to move along and behind the front as it moves across northern
portions of New York and New England.  Brief, but intense snowfall, along
with gusty winds, creating hazardous conditions, can be be expected within
these squalls.  Very cold air will be ushered into New England behind the
front under blustery north to northwesterly winds.  Temperatures are
forecast to dip below zero by Tuesday morning with subsiding winds as the
center of an arctic high approaches.

Snowfall downwind from the lower Great Lakes is expected to be enhanced
today as the arctic front passes through.  Farther west, low pressure
waves forming on the arctic front over northern High Plains will bring
periods of light snow from North Dakota eastward to the Great Lakes Monday
into Tuesday.
