   Areas affected...portions of western Minnesota

   Concerning...Heavy snow 

   Valid 151247Z - 151645Z

   SUMMARY...Periods of heavy snow (perhaps exceeding 1 inch/hr at
   times), along with blizzard conditions are possible this morning.
   Winds may sustain over 35 mph (with higher gusts), with reduced
   visibility possible in spots.

   DISCUSSION...A stacked cyclone continues to occlude while drifting
   toward Ontario. As this cyclone continues to track northward,
   continued CAA will keep the column below freezing while 850-700 mb
   frontogenesis will continue to support adequate convergence/lift for
   efficient dendrite production over central MN, which will pivot
   around the northwestern quadrant of the cyclone and support moderate
   to heavy snowfall over western MN this morning. Strong surface
   isallobaric flow across the northwestern cyclone quadrant may
   coincide with heavier snowfall rates (perhaps exceeding 1 inch/hr at
   times), resulting in periodic blizzard conditions. Visibility may
   reduce to or less than a quarter mile in the heavier snow bands.
