ROCHESTER, N.Y. (WROC) — With heavy snow headed our way Tuesday afternoon and evening, schools and businesses have begun to announce closures.

In terms of accumulations, we expect totals to vary wildly. As a general rule, the greatest accumulations will favor Wayne, Ontario and Yates counties (east) with emphasis across higher elevations. In these locations, totals in excess of half a foot are likely. As you go west, numbers drop. Same deal the closer you get to Lake Ontario. In these locations, no more than a few inches is expected.
