The potent low pressure system that began impacting Atlantic Canada on Sunday continues to bring heavy snow and freezing rain to some areas through the day on Monday. That prompted some school closures early Monday morning, with powerful winds behind the system also adding to the wintry mess. More on the timing and impact of this system, plus a look at the next one that closely follows and threatens more snow, below.

The bulk of the moisture from this potent system mostly departed the southern Maritimes early Monday morning, but the heavy snow will continue across northern New Brunswick, which prompted school closures amid deteriorating travel conditions.
Snow will gradually taper through the afternoon hours, but with some areas threatened with ice pellets and freezing rain before transitioning over to straight rain.
"The rain will also move across Newfoundland through Monday with 10-20 mm expected for most areas," says Weather Network meteorologist Kevin MacKay, adding the main widespread concern throughout the day will be the wind as strong easterly winds gust to 120 km/h at times.
"Then behind the low, southwest winds will continue across the Maritimes, gusting to 70 km/h along coastal areas and between 30-40 km/h for areas inland," says MacKay.
This flow will help to pump warm air and milder temperatures into the region on Tuesday, ahead of the next Colorado low that threatens significant snow by Thursday. The heaviest snow with this late week system is expected for areas north of the Bay of Fundy.
"This would be the first significant snow of the season for St. John&aposs, Newfoundland on Friday, but the snow is expected to change to rain across the Burin and Avalon Peninsulas," says meteorologist Dr. Doug Gillham.
Forecasters are also watching the potential for yet another significant system early next week, which could be a winter storm for a large part of the region.
