Nasty Winter Storm for Ontario

A big winter storm over the southern Appalachians is forecast to move north towards Lake Erie while deepening. The storm is expected to cut the forecast area in two traveling north towards Pembroke. West and north of the storm heavy wet snow is expected. Amounts will be in the 20-30cm range. East and south of the track heavy rain is expected from Oshawa east towards Cornwall. Here from 20-50mm of rain may fall. There is a potential for minor flooding along water ways. In all areas as the low pressure continues to deepen, winds will increase to between 40-60km/h with even higher gusts on Sunday. As the storm pulls to the north, cold air will flood into the area Sunday turning all rain to snow and blowing snow. Roads in the province will become icy and visibility will be limited. The same holds true for western New York and southeast Michigan where from 6-12 inches of snow may fall. The track may vary slightly which would make a big difference in precipitation type so stay tuned.
