Environment Canada is forecasting snow for much of the province on Wednesday, becoming heavy at times over the Avalon and Burin peninsulas, and possibly exceeding 15 centimetres.

A low pressure system will develop off the east coast of the United States tonight and deepen as it moves southeast of the Avalon Peninsula Wednesday evening.
Snow will develop over much of the island ahead of this system by Wednesday afternoon, and will become heavy at times over the Avalon and Burin peninsulas.
Although total snowfall accumulations exceeding 15 centimetres are likely by Wednesday evening, Environment Canada notes there is still some uncertainty in the exact track of this system.
For today, an intensifying low pressure system just off the Labrador coast will move northward across the Labrador Sea today. Rain will continue over southeastern Newfoundland, with additional accumulations of five millimetres expected before tapering off later this morning.
Over the Northern Peninsula, a brief period of westerly winds gusting to 100 km/h were expected early this morning in the wake of this system. Winds will diminish later this morning, but a strong, cold westerly flow will continue to prevail over the region into tonight. This will cause extreme wind chills near minus 35 overnight tonight.
