Late Season Snow Storm Tonight!

A late season snow storm is in store for the area tonight as low pressure moves to our south along a stalled frontal boundary. As this low moves along the front, cold air from Canada will advance south. Meanwhile, the low will throw moisture up into the cold air.

The precipitation will likely start as some rain later this afternoon and tonight. As that cold air moves in, however, it will change the rain to snow overnight. As is often the case with storms at the beginning and end of winter, the higher elevations will end up with more snow than the valleys. The models haven't been doing a good job with this storm so far; just yesterday they had us getting barely anything. However, they seem to be in better agreement with this morning's runs, and looking at the radars to our west, I think we are in for a decent snow. The map below is a little confusing since its hard to incorporate the elevation factor into the map. For downtown Groton, I would say 3 or 4 inches will fall. In the hills surrounding Groton, more like 5 or 6 inches. I think the highest amounts will be in the hills north, east and south of Cortland, especially down towards Binghamton. I wouldn't be surprised to see someone down there get 8-10", maybe even a foot!
