Storms Bearing Down on Atlantic Canada

Feb 9, 2012; 4:10 PM ET

A rapidly intensifying storm well southeast of Nova Scotia will pass close to Cape Race, Newfoundland, early Friday morning.

Last visible satellite image of the storm approaching Newfoundland from Thursday afternoon.

Temperatures are already marginal in St. John's, NL, as I write this and will have a hard time falling this evening with the southeast wind increasing. Despite this, snow should spread over southeastern Newfoundland later this evening then change to rain over the southern and eastern half of the Avalon Peninsula tonight. The rain will end as snow Friday morning as the storm moves past. I expect about 8-12 cm in the St. John's area with higher amounts to the west.

It looks like the storm will be mostly snow west and north of a line from Placentia to Carbonear on the Avalon. Locations such as Bonavista, Sunnyside and Port Blandford should end up with a solid 15-25 cm with lesser amounts north and west.

Weekend Storm to Target the Maritimes

Just as one storm pulls away, a second storm will quickly intensify east of Cape Cod, Mass., Saturday evening.

This particular storm will be loaded with moisture and will track much farther west compared to tonight's storm.

At this point, it looks like the center of this strengthening storm will pass across eastern Nova Scotia late Saturday night, which means mostly rain from Halifax on northeast into Cape Breton Saturday afternoon and night, though it may briefly start out as wet snow.

The rain will likely change to snow for a couple of hours early Sunday morning around Halifax with a small accumulation possible. Also watch for icy roads as temperatures drop steadily.

Look for the heaviest snow to fall across the southern and eastern two-thirds of New Brunswick, northwestern Nova Scotia and perhaps the extreme western end of PEI. Just east of this region there will be less snow due to rain/ice mixing in.

This will be a wind-blown rainstorm for southern and eastern Newfoundland on Sunday.
