...There is a Moderate to Heavy snow over parts of the Upper/Middle
Mississippi Valley on Saturday night...

...There is a Slight Risk of excessive rainfall over parts of the Pacific
Northwest on Monday...

...Light to Moderate snow over parts of the Northern Intermountain Region
and Northern Rockies...

On Saturday, a wave of low pressure over the Middle Mississippi Valley
will move northeastward to the Canadian Maritimes by Monday. The storm
will produce moderate to heavy snow over parts of the Upper/Middle
Mississippi Valley overnight Saturday and light to moderate snow over the
Lower Great Lakes moving into the Northeast Saturday night into Sunday.
Additionally, as low pressure moves through the Southeast, light to
moderate snow will develop over parts of West Virginia and
Central/Southern Virginia on Sunday night into Monday. Also, on Sunday
into Monday, rain will develop over parts of the Southeast with showers
and thunderstorms over the Florida peninsula.

Meanwhile, onshore flow from the Pacific will bring coastal rain to parts
of the Pacific Northwest through Monday. In addition, upper-level energy
will produce light to moderate snow over parts of the Northern Cascades,
Northern Intermountain Region, and Northern Rockies through Monday. On
Monday, moisture will bring heavy rain to parts of the Pacific Northwest.
Therefore, the WPC has issued a Slight Risk (level 2/4) of excessive
rainfall over parts of the Pacific Northwest on Monday. The associated
heavy rain will mainly cause localized flash flooding, with urban areas,
roads, small streams, and low-lying areas most vulnerable.

Lastly, low pressure moving out of the Northern Plains will move to the
Upper Midwest, producing light to moderate snow over the Upper Midwest and
Upper Great Lakes Sunday night into Monday.
