ROCHESTER, N.Y. – A low-pressure system that has produced a widespread wet snowfall for Western New York is already beginning to move off the east coast. The amount of snow has been small for Rochester with most of the accumulation on grassy surfaces. This is primarily due to marginally cold or borderline temperatures. Where temperatures are a few degrees colder, the accumulation will be a little greater and this is likely to be in the higher elevations south of Rochester. Snowfall will slowly taper and become more intermittent later this evening as drier weather is expected to return later Monday.
