Prospects For Snow Tuesday Night


The Northeastern US has been under a snow drought this season. Temperatures have been running well above normal through the fall and so far through the winter as well. This time last year we were dealing with much colder temperatures and the monster blizzard along the coast that paralyzed the megalopolis from D.C. to Philly, NYC and Boston. This year however, we haven't had much to talk about in the way of snow and cold. However, it does appear as if that is slowly about to change as several opportunities for snow are on the horizon for the Northeast over the next two weeks. I'm monitoring a storm system that will enter the picture on Tuesday producing rain for the Northeast along the coast; temperatures should be cold enough away from the coast across interior sections of the Northeast that rain can change to snow on Tuesday night. While a steady rain will fall east of Interstate 81 from eastern Pennsylvania to the Atlantic coast, snow can be expected across western Pennsylvania and upstate New York into northern New England. 1-3 inches of snow will be common across western New York and Pennsylvania with higher amounts between 6-12 inches across the higher terrain of northern New York State and Vermont by Wednesday morning as the storm system moves away from the region leaving behind a much colder air mass in its wake.
