   Areas affected...Central Minnesota into northern Wisconsin

   Concerning...Heavy snow 

   Valid 252332Z - 260530Z

   SUMMARY...Heavy snowfall with rates upwards of 1-2 inches/hour will
   spread east/northeast across central Minnesota into northern
   Wisconsin through the evening hours. Additionally, strong winds will
   continue to support areas of blizzard conditions, especially in open
   country and under heavier snow bands.

   DISCUSSION...Latest radar mosaics and surface observations show an
   intense cyclone over the Twin Cities area. Aloft, ascent associated
   with a narrow, but strong, zone of warm advection between 850-700 mb
   is overlapping with lift within the left-exit region of a 500 mb
   jet, which is supporting a broad swath of moderate to heavy snowfall
   rates from the Sisseton hills in northeast SD into west-central MN.
   These ascent mechanisms will continue to be favorably phased over
   the next several hours, and will support 1-2 inch/hour snowfall
   rates across central MN to northern WI and parts of the Upper
   Peninsula as the cyclone and surface freezing line shift east. Given
   the focused corridor of mesoscale ascent, snow banding will be
   possible and may support locally higher snowfall rates in excess of
   2 inches/hour. 

   In addition to the potential for heavy snowfall rates, 25-35 mph
   surface winds on the backside of the surface low are supporting
   areas of blizzard conditions with visibility below 1/4 mile recently
   noted on several web cams across western MN. Although temperatures
   will remain relatively warm (30-32 F), the combination of strong
   winds and moderate/heavy snowfall rates will continue to promote
   areas of blizzard conditions, especially across open country and
   under any heavier snow bands that develop.
