   SUMMARY...Blizzard conditions are expected to gradually increase   
   through the evening across portions of the Upper Midwest. 30-40 mph   
   sustained westerly winds will coincide with increasing snowfall   
   rates, resulting in reduced visibility, perhaps below a quarter   
   mile, in some instances.   
      
   DISCUSSION...Mesoanalysis indicates that the surface low, currently   
   at 993 mb and located over southern Lake Michigan, is continuing to   
   deepen while gradually drifting to the northeast. In response to   
   surface low intensification is a broadening and gradual   
   strengthening of the west-northwesterly surface wind field within   
   the low's northwestern quadrant. Surface observations show   
   widespread 30+ mph sustained wind speeds across much of western MN   
   into central IA. Meanwhile deep-layer cold air advection, and the   
   advection of mid-level moisture around the surface low, is resulting   
   in a broad band of snow pivoting around the low's northwestern   
   quadrant. As a result, moderate to perhaps occasionally heavy   
   snowfall rates will coincide with the 30+ mph west-northwesterly   
   surface wind field, which may strengthen further in tandem with the   
   low. Increasingly common blizzard conditions may manifest, with   
   reduced visibility down to or below a quarter mile where the heavier   
   snow bands and wind gusts may overlap.
