Messy system to bring rain, heavy snow to parts of Atlantic Canada

Saturday, November 27th 2021, 8:51 am - After flooding rains from earlier in the week, a round of heavy snow and kick off the weekend across Atlantic Canada as the unsettled pattern will be hanging around for the next several days.

The unsettled weather continues for Atlantic Canada this weekend, though not nearly as impactful and extreme as seen earlier in the week across Nova Scotia and Newfoundland. Saturday will see a bout of showers linger into portions of the Maritimes, while pushing into Newfoundland, after a new low-pressure system made its way in Friday overnight. Amounts won't be excessive, but could worsen already flood-ravaged areas from this week. The low is also bringing heavy snow to New Brunswick, with up to 20 cm possible in the hardest-hit areas through Saturday. Special weather statements are in effect. More on the timing and impacts, below.


The low-pressure system that made an entrance Friday night will continue to track north through Atlantic Canada Saturday, bringing more showers for Newfoundland and snow for New Brunswick, and parts of Nova Scotia.

Since the heaviest rains fell overnight Friday, additional rainfall will be rather minor in comparison to what was dumped on the region earlier this week.

Widespread totals of 5-15 mm is expected across Atlantic Canada through Sunday morning. However, in eastern Nova Scotia and western Newfoundland, this could worsen already flood-hit areas.

The system is also bringing snow as cold temperatures descend Saturday, mainly to New Brunswick, with just a light dusting in northern Nova Scotia due to sea influence. In the former, snowfall will be heavy at times and may make travel difficult. The precipitation will taper off in the evening from the southwest to northeast.

Accumulations will hit 15-20 cm in the northern and western sections of New Brunswick, mainly over higher terrain, with totals of 5-15 cm elsewhere. Fredericton may see 10 cm. Special weather statements are in place.


"Be prepared to adjust your driving with changing winter road conditions," says Environment and Climate Change Canada in the statement. "When clearing snow from your property, remember to take frequent breaks."

Across the gulf, western Newfoundland may see some sea-effect flurries Saturday and for much of Sunday, ending in the evening during the latter.


On the heels of this system, forecasters are keeping an eye on the next low-pressure system that looks to develop off the U.S. East Coast and rapidly intensify as it tracks into Atlantic Canada Monday and Tuesday.

This will bring widespread rain and windy conditions to the region, as well as the potential for ice pellets, freezing rain and snow. As well, temperatures remain very mild to the east of the storm track, and daytime highs reaching into the lower teens will be possible for eastern Newfoundland.


"However, a swath of significant snow is expected to the west of the storm track and for parts of New Brunswick, eastern Quebec and into Labrador," warns Doug Gillham, a meteorologist at The Weather Network.

Conditions will then turn colder as the storm departs. Another system is possible by mid- to late week.
