MD 0065 CONCERNING SNOW SQUALL FOR SOUTHERN MAINE
Mesoscale Discussion 0065
NWS Storm Prediction Center Norman OK
0308 PM CST Sun Jan 14 2024
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.
