As the front moves eastward through the Mississippi Valley, snow
will continue to develop behind it in the Northern Plains. The
storm is forecast to consolidate farther north over northern
Minnesota and remain quasi-stationary there through Saturday.
Thus, heavy snow will persist across the Northern Plains and Upper
Mississippi Valley on the backside of the storm. Additional
snowfall of over a foot is likely across northern/central North
Dakota while 6 to 10 inches are expected for parts of northwestern
Minnesota. Blowing snow is also expected, with blizzard conditions
possible. Some mixed precipitation is also possible for portions
of the Dakotas and Minnesota along the transition zone between
snow and rain. 

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