The low pressure system will continue to weaken as it pushes
eastward toward the Southern Plains. As the upper level energy
associated with this low pressure system continues moving
eastward, it will lift up into the Northern Plains and Upper
Midwest tonight and into tomorrow. An Arctic cold front will also
drop southward across these states, bringing frigid air to these
regions. This will lead to heavy snowfall across northeastern
Montana, northern North Dakota and into northern Minnesota. Expect
snowfall amounts in these regions to range 6 to 12 inches with
locally heavier amounts. Light freezing rain mixing with sleet and
snow can also be expected for parts of the Upper Midwest and
portions of the Great Lakes. Meanwhile, another digging trough off
the West Coast will continue to bring heavy snowfall for the next
few days across the higher elevations of the western states,
including the Sierra Nevada, the Oregon Cascades, and higher
elevations of the northern and central Rockies in addition to the
higher elevations of the Central Great Basin. Overall, the Sierra
Nevada can expect snow totals of up to 6 feet through Monday
evening. 

The next storm summary will be issued by the Weather Prediction
Center at 100 PM PST. Please refer to your local National Weather
Service office for additional information on this event.
