   Areas affected...The Eastern Dakotas into west and northwest   
   Minnesota   
      
   Concerning...Blizzard=20   
      
   Valid 181509Z - 182015Z   
      
   SUMMARY...Blizzard conditions are expected to continue across parts   
   of the eastern Dakotas and into parts of west/northwest MN through   
   early/mid afternoon.   
      
   DISCUSSION...Latest surface observations and web cams from southeast   
   SD northward through the Red River Valley of the north show   
   widespread visibility reductions to 1/4 mile or less with some areas   
   experiencing white out conditions - especially across northeast ND   
   into northwest MN where moderate to heavy snowfall rates are   
   contributing to the visibility reductions under a developing snow   
   band. Heading through the afternoon, the strongest push of low-level   
   cold advection should migrate from the eastern Dakotas into southern   
   MN/northern IA. Although the heaviest snowfall will likely shift   
   eastward into northern MN through the day, light snow and persistent   
   strong northerly winds will continue to support blizzard conditions   
   through the Red River Valley through at least mid-afternoon and   
   possibly until around 00z. Further south/southeast, the antecedent   
   snow pack is not as widespread compared to locations further north,   
   but a combination of light to moderate snowfall and intense surface   
   winds (gusting between 40-50 mph) will likely contribute to areas of   
   blizzard conditions into west/southwest MN.
