   Areas affected...Northeast Montana

   Concerning...Heavy snow 

   Valid 042046Z - 042315Z

   SUMMARY...A snow band will lift across northeast Montana over the
   next 2 hours bringing snowfall rates in excess of 1.5 inches per
   hour within the heaviest band.

   DISCUSSION...A band of heavy snow has developed in a region of
   moderate isentropic ascent across northeast Montana, on the western
   extent of strengthening low to mid-level frontogenesis. This band
   will continue to lift northeast through the afternoon. The transient
   nature of the band may limit higher accumulations in any one
   location, but snowfall rates of 1.5+ inches per hour will be
   possible for an hour or two as the band passes.
