   Areas affected...northeastern North Dakota...northern
   Minnesota...northern Wisconsin

   Concerning...Heavy snow 

   Valid 122150Z - 130145Z

   SUMMARY...Heavy snow will overspread portions of northeastern North
   Dakota, northern Minnesota, and northern Wisconsin tonight with
   snowfall rates likely range 1-2 inches per hour at times.

   DISCUSSION...A deepening surface low will shift southeastward from
   North Dakota into southern Minnesota this afternoon into tonight.
   Strong low-level warm air advection within the 900-700 mb layer
   aided by DCVA ahead of a mid-level shortwave trough and favorable
   jet streak dynamics are expected to combine to promote strong ascent
   within the dendritic growth zone. This will support heavy snowfall
   along and north of the track of the surface low, with rates 1-2
   inches per hour at times.

   A strong surface pressure gradient on the northwestern periphery of
   the surface low will support the potential for sustained northerly
   winds at 30 mph, with the potential for wind gusts to 50+ mph. Given
   this, blowing snow is likely, with brief periods of blizzard
   conditions possible, especially across the northern Red River Valley
   late this evening.
