   Areas affected...Northern ME

   Concerning...Heavy snow 

   Valid 042006Z - 050100Z

   SUMMARY...Heavy snowfall rates in excess of 1"/hour will continue to
   spread into portions of northern ME this afternoon and evening, with
   higher snowfall rates of 2-3"/hour likely.  This heavy snow will
   combine with strong winds to produce blizzard conditions across the
   region.

   DISCUSSION...The latest composite radar imagery shows heavy snow
   bands moving northward into portions of northern ME, associated with
   mid-level frontogenetic forcing (see previous MCD #6). Heavy snow is
   being reported at several stations across the region, and these
   conditions should continue into the evening. The period of at least
   1"/hour snowfall rates appears most likely between 20z-03z.
   Low-level warm air advection associated with the
   approaching/deepening surface low should lead to steepening
   mid-level lapse rates, with the potential for enhanced vertical
   motion and heavy snowfall rates of 2-3"/hour rates possible between
   21z-00z.
