A well-defined warm front extended east of the low into the lower Midwest and Ohio Valley, while a cold front extended southwestward into the central and southern Plains. Latest RADAR and surface observations indicated a band of moderate to heavy snow situated along an axis extending from northern South Dakota into eastern North Dakota and Minnesota. Blizzard conditions were ongoing in this region with maximum sustained winds of 25-35 mph and visibilities dropping below a mile. Furthermore, a large temperature gradient along the warm front was observed with temperatures in the central Plains ranging from the upper 40s to the teens from south to north, to 70s and 80s south of the boundary.

Additional snowfall totals of 8-12" across eastern North Dakota and northern Minnesota will be possible through Wednesday night, including localized areas of 12-18". The combination of strong winds and heavy snow will create whiteout conditions and significant drifting snow through Wednesday, causing dangerous to impossible driving conditoins and considerable disruption to daily life. In addition to snowfall impacts, freezing rain will also be a concern for portions of Wisconsin and the Upper Peninsula of Michigan, where 0.10 - 0.25" of ice accretion will be possible over the next 24 hours causing isolated power outages and slippery travel. High winds following the event will continue to create dangerous travel conditions due to significant blowing snow, even if snow is not falling. Furthermore, as the system tracks northeastward, there is increasing confidence of significant freezing rain impacts spreading into portions of New England, especially in New Hampshire and Maine on Wednesday and Thursday. The next Storm Summary will be issued by the Weather Prediction Center at 1000 AM CDT. Please refer to your local National Weather Service office for additional information on this event. Russell $$
