A low pressure system currently over the US Midwest will make its way eastwards over the next day or so and will arrive in Newfoundland and Labrador as early as Friday morning.
Snow appears likely over most of Newfoundland before changing to rain on Friday evening.
Snowfall amounts are not expected to be significant for most the Island. However the Northern Peninsula may pick up at 20+ cm and Corner Brook might get 10+ cm.
In Labrador the bulk of the precipitation appears to be in the form of snow, some mixing is possible for southeastern areas such as Blanc-Sablon to Red Bay. A heavy line of snow from Labrador across the TLH to Happy Valley-Goose- Bay may receive significant snow. 30 cm is not out of the question.
Winds will be gusty as well. On Sunday as the low pushes away winds will intensify. As the low moves away some wrap around snow is possible along the west coast of Newfoundland.
