...Stormy weather for the Pacific Northwest and Intermountain

...Snow expected in the Upper Midwest and Great Lakes..

...Cold weather for the northern tier states...

Snow showers continue to fall across the Ohio Valley and into the
Northeast as the nor'easter moves further east into the Atlantic. 
Snow can still be expected in the Mid-West, Great Lakes, and
northern Appalachians regions through the remainder of
Thanksgiving night.  In addition, colder than normal temperatures
will persist for the the eastern half of the country through the
first half of the weekend. 

There is quite the impressive frontal system moving through the
Pacific Northwest and the Intermountain West. This boundary will
slowly make its way south, and behind it very cold Arctic air will
follow. Higher elevation snow and moderate rainfall can be
expected throughout these regions along with strong winds.
Currently, the precipitation is mostly light to moderate along the
Cascades.  However, by Friday and into Saturday it will become
more widespread across the Intermountain West and into the
northern Plains.  By Friday night, the heavier snow amounts will
begin to approach the northern Rockies in Idaho and northwest
Montana.  On Saturday, as the Arctic front dips across the
northern Plains, the heavier snowfall will begin to advance across
northern Montana and into North Dakota. 

Snow begins to move into the Upper Midwest by late Thanksgiving
night and Friday morning.  There is already lake effect snow on
the lee side of the lakes.  However once the surface boundary
associated with the Pacific Northwest system begins approaching
the Upper Midwest, snow will be more widespread.  By Saturday,
snow will begin to taper off in this region and will be confined
to the Upper Great Lakes. 

Cold weather will continue for the northern Plains and Upper
Midwest as a Canadian surface high governs the weather pattern. 
Quiet weather is expected from the Southwest through the Gulf
Coast during the short term period.
