...Rain and higher elevation snow are expected over parts of the Pacific
Northwest and Northern Rockies...

...There is a Marginal Risk of excessive rainfall over parts of Northern
California on Monday into Tuesday morning...

...Temperatures will be 10 to 30 degrees above average over the
Northern/Central High Plains into the Upper Midwest...

Weak onshore flow and upper-level troughing will aid in producing rain and
higher elevation snow over the Pacific Northwest/Northern California into
the Northern Rockies through Tuesday. Moisture will surge onshore ahead of
the next system which will be moving across the Eastern Pacific overnight
Monday. An associated atmospheric river will be directed toward
Northern/Central California bringing periods of heavy rain and higher
elevation snow to the region Monday afternoon through Tuesday. As a
result, the WPC has issued a Marginal Risk of excessive rainfall Monday
into Tuesday morning over parts of Northern California.

A front draped from the Upper Midwest to the Great Basin will move
eastward extending from the Great Lakes into the Southern Plains by
Tuesday.  Today, ahead of the front, temperatures will surge 10 to 30
degrees above average over the Northern/Central High Plains into the Upper
Midwest.

Meanwhile, low pressure off the Southeast Coast will continue to move
eastward out over the Atlantic. As a result, rain and gusty winds will
diminish through the day.
