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. ..Moore.. 01/14/2024 ...Please see www.spc.noaa.gov for graphic product...
