4:36pm Binghamton radar shows snow (blue) and rain (green) spreading across the area. The rain-snow line has set up from just south of Ithaca and Cortland to Norwich, but will retreat further south as the evening goes on.

Precipitation is increasing in both coverage and intensity late Sunday afternoon. Snow is widespread across much of the Finger Lakes, with most of the mixed precipitation now locked in across the Southern Tier.

Here in Groton, the temperature has dropped from 40º at 2pm to 29º at 4:50pm. Similar drops have occurred in other areas that are close to the front as cold air seeps south. This will continue to push the rain-snow line further south. Chances are, if it is snowing where you are at now, it will remain snow for the duration of this storm.

Western New York is loading up with precipitation with more widespread heavier snow. This will work east across the Finger Lakes this evening.

Snow will continue into the morning hours as low pressure tracks east across the Mid-Atlantic, and through the day on Monday as the same low pressure turns north off the east coast. All in all, the storm is behaving more or less as expected, though some of the finer details have been a little off- as was expected to be the case.

Be safe- this event is just getting started.
