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. ..Broyles.. 02/13/2017 ...Please see www.spc.noaa.gov for graphic product...
