As the front moves slowly eastward through the Plains and into the
Mississippi Valley, snow will continue to develop behind it in the
Northern and Central Plains. The Central Rockies will see snow
continue to taper through this afternoon. The storm is forecast to
consolidate farther north in northern Minnesota tonight and remain
quasi-stationary there through Saturday. Thus, heavy snow will
persist across the Northern Plains on the backside of the storm.
Historic October snowfall totals are likely across portions of the
central and eastern Dakotas - where a swath of accumulations well
exceeding 24 inches is expected in east-central North Dakota.
Farther east, accumulations of 6 to 10 inches are expected across
northwestern Minnesota. Blowing snow is also expected, with
blizzard conditions possible. Some mixed precipitation is also
possible for portions of the Dakotas along the transition zone
between snow and rain.

The next Storm Summary will be issued by the Weather Prediction
Center at 900 PM MDT. Please refer to your local National Weather
Service office for additional information on this event.
