...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 and blustery
conditions across the Great Lakes and Northeast on Sunday...

Precipitation associated with an approaching Pacific system will continue
to spread east across the Pacific Northwest this evening and through the
overnight, before reaching into the northern Rockies tomorrow morning.  A
Winter Storm Warning is in effect for the Olympics and Winter Weather
Advisories are in effect for portions of the northern Cascades, where
several inches of heavy wet snow can be expected by early tomorrow.  This
system is forecast to weaken, however unsettled weather is likely to
continue, with additional heavy precipitation possible through Monday as
another system approaches the region.  Heavy rain falling across the lower
elevations may cause flooding concerns across portions of western
Washington and Oregon on Monday.

Across the South, an upper level disturbance will support generally light
precipitation moving east from eastern Texas and Oklahoma through the
lower Mississippi Valley and into the Tennessee Valley overnight, before
spreading across the southern Appalachians and into the southern Mid
Atlantic tomorrow morning.  Shallow low-level cold air may support a
wintry mix from the ArkLaTex region into the Tennessee Valley.  However,
significant snow or ice accumulations are not expected.

Across the Great Lakes and Northeast, a strong cold front will sweep
across the region tomorrow afternoon and 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 developing squalls.
