...Modest atmospheric river activity to bring multiple rounds of
beneficial precipitation across the Pacific Northwest and the Northern
Rockies for the rest of the weekend into early next week...

...A round of mixed light rain and snow may brush the northern borders of
the northern Plains to the upper Great Lakes Sunday to Monday...

...Fair and mild weather expected to continue from the southwestern U.S.
to much of the eastern U.S....

Unsettled weather is expected to prevail across the northwestern portion
of the country as a series of frontal systems associated with multiple
Pacific cyclones push toward the Pacific Northwest.  Rounds of moderate to
locally heavy precipitation can be expected through Monday as these
systems move onshore.  The current round of mostly rain across Washington
and Oregon is forecast to push farther inland tonight and bring
high-elevation snow and low-elevation rain across the northern Rockies on
Sunday.  As a low pressure center develops over the northern High Plains
on Sunday and tracks toward the upper Midwest Sunday night, a round of
mixed rain and snow may brush the northern borders of the northern Plains
to possibly the upper Great Lakes starting Sunday to Monday.  Rain is
expected to spread from the upper Midwest later on Sunday to much of the
Great Lakes Sunday night, reaching into western New England on Monday. 
Meanwhile, the next surge of moisture from the Pacific will reach the
Pacific Northwest later on Sunday and will persist into Monday.  The
leading edge of the moisture will then penetrate further inland and bring
the next round of elevation-dependent rain/snow across the northern
Rockies on Monday.

As the unsettled weather continues over the Pacific Northwest, fair and
mild weather will continue from the southwestern U.S. through the central
and southern Plains as well as much of the eastern U.S. for the next few
days thanks to a relatively zonal upper-level flow across the southern
tier of the country.  Shortwave energy behind a front over the Southeast
will lead to average to below average temperatures.  Slightly milder than
normal temperatures are expected to continue over the Pacific Northwest
amid the unsettled weather.
