Thursday, February 18th 2021, 6:00 pm - Special weather statements are already in effect for system that could spread significant snow to parts of Atlantic Canada this weekend
An amplified jet stream and an active storm track will bring the chance for more wintry weather to Atlantic Canada late Friday and into Saturday. Presently, the storm system in question looks to pass south of the region with the heaviest snow well out to sea, but its northern edge has a chance to brush southern parts of Nova Scotia and Newfoundland's Avalon peninsula. Some 10-15 cm is possible, but the forecast is not yet set in stone, and will depend on how the storm's track shakes out. What we know, below.
- Next system moves south of the region Friday night, northern edge brings snow potential to Nova Scotia and Newfoundland
- 10-15 cm possible for Atlantic coastal Nova Scotia and parts of Newfoundland's Avalon peninsula
- Forecasters monitoring potential system early next week
INTO THE WEEKEND: CHANCE FOR SIGNIFICANT SNOW AS U.S. SYSTEM PASSES TO THE SOUTH
An active storm track looks to bring this latest brush with winter weather into Atlantic Canadian waters later Friday, a system which has brought uncommonly cold and wintry conditions to parts of the southern U.S.
On the one hand, there will be more than enough Arctic air still in the mix to ensure that whatever this system brings will remain as snow. On the other, its track is largely out to sea, so it will only deliver a glancing blow to parts of Atlantic Canada, rather than a wide-ranging hit.
Nevertheless, even as late as Thursday night there was still some uncertainty in the storm's exact track – a slightly more northern tack could boost snowfall totals.
Presently, forecasters expect the snow to start in southwestern Nova Scotia in the afternoon Friday, reaching Halifax by late Friday evening, with the heaviest snowfall overnight. In Newfoundland, snow will start Saturday afternoon and continue into Sunday morning
Around 10-15 cm is possible for areas along and a bit inland of Nova Scotia's Atlantic shore, as well as the southern Avalon in Newfoundland, but those amounts could change as the system nears and the forecast tightens up.
Special weather statements are already in effect for the southern half of Nova Scotia, warning of the potentially heavy snow.
The snow looks to taper through the day on Saturday.
Beyond, another system is expected to intensify as it tracks into Atlantic Canada early next week. It is too early to have confidence in the track and impacts, but parts of the region should see significant snow and possibly a messy mix of precipitation, though continued monitoring will be needed.
