Nova Scotia, eastern P.E.I., and the Bay of Fundy area of New Brunswick should expect slippery, snow-covered roads for Wednesday morning. Even with some rain mixing with the snow, much of Nova Scotia can expect 5-to-15 cm of snowfall. Parts of eastern P.E.I. and the Bay of Fundy area of New Brunswick will pick up 5-to-10 cm of snow. The remainder of the Maritimes will see 5 cm or less. The mix of snow and rain will be clearing northeast of the region quickly Wednesday morning. Even Cape Breton should be out of the snow by around 10 a.m. Wednesday. The afternoon will see a mix of sun and cloud, with high temperatures climbing into a range of 3-to-8 degrees. Much of the freshly fallen snow should melt during the day.
