Next storm targets Newfoundland with heavy snow

The deadly winter storm that cut across the central United States this weekend has its sights set on Atlantic Canada for the week ahead. While it looks like much of the Maritimes may miss out on the bulk of the impacts from this round of wintry weather, Newfoundland won't be so lucky. Forecast confidence is increasing that heavy snow, strong winds, and a wintry mix are will blast the province through mid-week, while Arctic air keeps its icy grip on the rest of Atlantic Canada. We take a look at how much snow to expect, and why the track of this storm is so important to its impacts, below.

WEATHER HIGHLIGHTS

  • Major storm departs U.S. coast, heads toward Atlantic Canada for Tuesday
  • Heavy snow expected for parts of Newfoundland; glancing blow possible for Nova Scotia
  • Strong winds will lead to whiteout conditions at times
  • Cold temperatures persist, fall further this week

High pressure across eastern Canada has thus far kept the major winter storm marching across the U.S. Midwest south of the border, but as the storm moves offshore, that barrier will break down, allowing the potent low pressure centre to surge north -- and that puts Atlantic Canada right in its path. That makes for a slightly tricky timing forecast, as the exact track of the low will depend a lot on how that ridge of high pressure breaks down, but models seem to be converging on a track that takes it right into eastern Newfoundland.

TIMING

While it seems likely that the Maritimes will sit this one out, there are still some model differences that The Weather Network forecast centre is watching -- a track further to the west would see parts of Nova Scotia, particularly Cape Breton Island, getting hit with strong winds and snow early Tuesday.

It's Newfoundland that's unlikely to escape this storm, however, with the leading edge of snow and strong winds likely to arrive on the Avalon by Tuesday afternoon. The low continues to sail past offshore through Wednesday, keeping the focus for the heaviest snow largely confined to eastern Newfoundland and the Avalon Peninsula. A special weather statement was issued on Sunday in advance of the system for the Avalon, Burin, and Bonavista peninsulas.

 As warm air draws north with the system, we may see a changeover to a wintry mix or even just rain for parts of the Avalaon through Tuesday night. This increase in temperature in the wake of fresh snowfall also raises concerns for localized flooding, due to snow melt.

COLD AIR PERSISTS, INTENSIFIES

That warm-up will be temporary, however, as Arctic air is reluctant to release its hold on eastern Canada. Another system, passing mainly to the north through Quebec and northern Labrador, will open the floodgates for another round of Arctic air to sink down into the region for later this week.

Temperatures are expected to moderate somewhat, but generally remain below average into next week.
