...Active weather will continue across the Pacific Northwest into
the Intermountain West this weekend...

...Additional snow and ice expected for parts of the northern
Plains and Upper Midwest...

...Severe weather potential in the southern Plains by Monday...

A robust upper level low off the Pacific Northwest coast will
begin to move inland by overnight into Sunday morning.
Precipitation is expected to continue across the coastal portions
of the Pacific Northwest in addition to the Intermountain West and
Great Basin.  In addition, higher elevation snow is expected
across the Shasta and Siskiyou ranges as well as the northern
portions of the Sierra Nevada mountains into Sunday. As the upper
trough moves farther inland by Sunday, it will lead to an increase
in precipitation across the Rockies in addition to higher
elevation snow for the northern Rockies. By Monday, most of the
precipitation across the West will taper off with the exception of
a few light snow showers in the higher elevations of the northern
and central Rockies. The Pacific Northwest will maintain a period
of rain/higher elevation snow as a plume of moisture continues to
deliver precipitation throughout the weekend and into early next

The chance for wintry precipitation returns for the northern
Plains and Upper Midwest by Sunday.  A band of snow will begin to
move across the northern Plains by Sunday morning. Snowfall rates
will increase throughout the day, with the heavier band of snow
moving through central Minnesota by Monday evening. Snow will lift
to the north over the arrowhead of Minnesota by Monday night. In
addition, ice will also be an issue especially in the southern
Minnesota/Iowa border on Monday.

Farther south, showers and thunderstorms will move across the
Southeast overnight and into Sunday as a frontal boundary also
moves south across the region.  The heavier precipitation will
move offshore by Sunday night with lighter showers still lingering
near the central Gulf Coast.  By Monday, thunderstorms will fire
off along the dryline in West Texas.  Some of these storms could
be severe; as such, the Storm Prediction Center has a slight risk
of severe weather from the Big Bend region to northeastern
