At 900 PM CDT...A strong low-pressure center was analyzed in
southwestern Iowa, with a minimum pressure of 989 mb (29.21 in
Hg). 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. As a result, severe thunderstorms have been ongoing in
the system's warm sector with expansive Severe Thunderstorm and
Tornado Watches valid through late Tuesday evening across the
central Plains and lower Midwest

The low-pressure system will continue to further deepen and track
northeastward across the Midwest, producing heavy snow rates of
1-2"/hr at times. 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.
