MD 0175 CONCERNING HEAVY SNOW FOR MAINE
Mesoscale Discussion 0175
NWS Storm Prediction Center Norman OK
0610 AM CST Mon Feb 13 2017
Areas affected...Maine
Concerning...Heavy snow
Valid 131210Z - 131815Z
SUMMARY...Heavy snowfall will continue across much of south-central
to eastern Maine this morning with snowfall rates of 1 to 2 inches
per hour possible within the most concentrated bands. Blizzard
conditions will also be possible near the coast of Maine from
Augusta to Eastport and inland to about 80 statute miles.
DISCUSSION...An upper-level low will move quickly offshore from near
Cape Cod today as a surface low rapidly deepens about 180 statute
miles to the southeast of the eastern tip of Maine. This surface low
will bomb out to about 972 mb by midday as a Nor'easter continues
across northern New England including the eastern half of Maine. As
this occurs, deep-layer vertical motion to the north of the
upper-level low will become very strong maintaining and even
increasing snowfall rates over the next 2 to 4 hours. This
enhancement of large-scale ascent is already becoming evident on IR
imagery with rapid and expansive cloud top cooling evident over
southern Maine. The heaviest snowfall is expected to occur along a
corridor from near Augusta northeastward through the Bangor vicinity
to the Canadian border to the north of Eastport where snowfall rates
could reach 2 inches per hour within the heaviest bands. Blizzard
conditions will also be possible along this corridor where
tightening surface pressure gradients will create wind speeds from
25 to 35 mph with gusts to 45 mph.
