Monday, January 21, 2019, 7:33 PM - Atlantic Canada got the tail end of a powerful winter storm that slammed much of eastern Canada and the northern United States, but though the snow has largely ceased, some snow streamers linger Tuesday for Newfoundland, and forecasters are watching the potential for a new system Thursday.
Read on for what we know so far.

WEATHER HIGHLIGHTS
- Rain continues through Newfoundland, tapering off into Tuesday morning
- Snow streamers continue for parts of Newfoundland, and possibly Cape Breton
- Forecasters monitoring possible system Wednesday night to Thursday
WATCH BELOW: ATLANTIC CANADA TEMPERATURES
Atlantic Canada took a serious hit from this system as it passed, dropping heavy snow in New Brunswick, torrential rains in Nova Scotia, and a period of freezing rain for areas around and north of the Bay of Fundy.
On top of that, a precipitous drop in temperatures -- more than 20 degrees in 24 hours -- caused severe flash freeze, while areas that saw torrential rain experienced localized flooding, with the ground too frozen to be able to absorb the runoff. The result was flight and ferry cancellations, power outages, and school closures.
Newfoundland also experienced a mix of precipitation types, and it is the last to see relief, with some 5-10 mm of rain likely overnight for parts of the south coast, locally reaching 20 mm in some places.
WATCH BELOW: LINGERING SNOW ATLANTIC CANADA
Unfortunately for Atlantic Canada, that won't be the end of this system. While the main area of precipitation moves out, low pressure is set to stall over the region as a ridge of high pressure over the Atlantic makes for a weather 'traffic jam' that will keep onshore snow streamers flowing for western Newfoundland, and exposed parts of the Maritimes -- like Cape Breton -- into Tuesday and early Wednesday. And that leaves only a moment to catch your breath before yet another system moves in; something models are hinting at for Thursday.
"Another moisture laden system that's tapping into subtropical moisture will develop along the U.S. east coast and track into Atlantic Canada Wednesday night into Thursday," says Weather Network meteorologist Dr. Doug Gillham. "It will bring primarily rain for the central and southern Maritimes and most of Newfoundland, but a period of snow and ice for central and northern New Brunswick."
Arctic air will also spread into the region behind the storm with more sea-effect snow and the potential for yet another storm early next week.
