A powerful storm that plunged Texas into a deep freeze in recent days is now pushing south of Atlantic Canada, though with much less impact compared to the Lone Star State. The system is grazing the southern areas of Nova Scotia and Newfoundland with modest amounts of snow Saturday, and while temperatures will drop in behind it Sunday, the plummet won't be nearly as severe as stateside. About 10 cm of snow is expected for much of Nova Scotia and Newfoundland's Avalon Peninsula. Special weather statements are in place for the former. Beyond, another system will target the region for early next week with rain and snow. More on the impact and timing with the current low, and what's ahead, below.
Northern edge of the offshore low will bring snow to Nova Scotia and Newfoundland through Sunday morning
10 cm possible for Atlantic coastal Nova Scotia and parts of Newfoundland's Avalon Peninsula
Forecasters monitoring potential system early next week
SATURDAY: U.S. SYSTEM BRUSHES ATLANTIC WITH SNOW
A deadly and impactful storm that has brought uncommonly cold and wintry conditions to parts of the southern U.S continues to track into the Atlantic Ocean, and as it does so, is grazing southern Nova Scotia and Newfoundland as it passes by well offshore.
Because there will be will be plenty of Arctic air in place, the event is manifesting as all snow. The amounts won't be significant like recent storms have delivered, however.
Snow has already begun in southwestern Nova Scotia, but a dry northeasterly flow in low levels has delayed the onset of snow in other parts of the province. Accumulating snow will begin elsewhere Saturday morning. Special weather statements blanket most Nova Scotia. Snow will diminish in the evening hours.
While the low will stay well south of the Atlantic provinces, moisture from it may push far enough north to provide some light accumulations in southern New Brunswick and across P.E.I,, as well.
The snow will reach the Avalon Peninsula in Newfoundland by Saturday evening, continuing overnight and diminishing to flurries by Sunday morning.
Around 10 cm is possible for areas adjacent to and somewhat inland of Nova Scotia's Atlantic shore, as well as the southern Avalon in Newfoundland.
"The storm's track will keep the strongest winds and heaviest precipitation out to sea, but enough moisture should push back into the Arctic air in place over the region to produce the 10-15 cm of snow for places like Halifax," says Weather Network meteorologist Michael Carter.
By Sunday, temperatures will plummet across the Maritimes and Newfoundland, thanks to the northerly flow. Many places in Newfoundland will see their coldest temperatures of the season into Monday. However, temperatures will quickly rebound by mid-next week.
LOOK AHEAD: NEXT SYSTEM TO BRING RAIN, ANOTHER SHOT OF SNOW
Beyond the weekend, a storm will intensify off the northeastern U.S. coast and track into Atlantic Canada Monday night and Tuesday. The exact track is still uncertain, but a path across Nova Scotia and P.E.I. appears most likely.
This would bring mostly rain to southern Nova Scotia and snow changing to rain around the Bay of Fundy and P.E.I. -- with 5-10 cm possible before the changeover -- with mostly snow for northern New Brunswick.
Precipitation will be mostly rain for southeastern Newfoundland and snow changing to rain for much of southern and central areas. There is also the potential for another significant system to impact the region late-week.
