   Areas affected...Southern Maine

   Concerning...Snow Squall 

   Valid 142108Z - 150115Z

   SUMMARY...Snow squalls potential should begin to gradually decline
   through the evening hours amid the onset of nocturnal cooling.
   However, impactful snow squalls should continue in the near-term
   (next 1-2 hours) across southern Maine.

   DISCUSSION...Snow squalls continue to spread east across the New
   England region with several reports of significant visibility
   reductions and rapid snow accumulations (upwards of 1-2 in/hour snow
   rates). This trend should continue for the near term (next 1-2
   hours) as the broken line of convective showers along the front
   pushes into southern Maine. However, downstream temperatures have
   fallen slightly over the past 30-60 minutes due to the onset of
   nocturnal cooling. Further temperature reductions are likely given
   scattered cloud cover ahead of the approaching cold front. Recent
   forecast soundings suggest that buoyancy and low-level lapse rates
   will diminish as temperatures fall into the upper 20s, which should
   modulate the convective intensity of the snow squalls. Consequently,
   a gradual weakening trend is anticipated beyond the next 2-3 hours
   as temperatures fall from the mid 30s into the upper 20s ahead of
   the front.
