The wider storm
A storm system produced heavy snow, strong to damaging winds, and minor coastal flooding in southern New England. This was a tough storm to forecast. Although it was not deep low pressure and although it passed just south of the 40N/70W benchmark, its precipitation shield was expansive because of a broad 700 mb low over southeast New England, abundant moisture, and a very cold air mass in place. By far, the heaviest snow fell to the north (Laconia, NH) and west (Binghamton, NY), where more than 3 feet fell. But amounts ranged from 10 to 20 inches across much of southern New England. There was some minor coastal flooding at the time of high tide and also a flash freeze in eastern Massachusetts as the storm pulled away to the northeast.
