Saturday, February 20th 2021, 7:45 pm - A system tracking well south of Atlantic Canada brought heavy snow Saturday for much of Nova Scotia and parts of Newfoundland.
A powerful storm passed south of the Atlantic provinces Saturday, and though leaving behind very heavy snow and deep cold in its U.S. origins, it was far enough out to sea that it only clipped Canadian territory, bringing moderate snow to Nova Scotia and Newfoundland's Avalon Peninsula. The last of the flakes will taper off in Newfoundland Friday, with temperatures falling to some of their lowest levels this season. For a closer look, see below.
- Snow tapers to flurries in Newfoundland through Sunday morning
- 10 cm possible for Atlantic coastal Nova Scotia and parts of Newfoundland's Avalon Peninsula between Saturday and Sunday
- Forecasters monitoring potential system early next week
INTO SUNDAY: SYSTEM EXITS, LINGERING EFFECTS IN NEWFOUNDLAND
Abundant cold air boosted the snow potential of this system, but the amounts that feel were relatively limited, given its track far out to sea.
By Saturday evening, it was all but finished in Nova Scotia, where up to 10 cm was possible. Around the same time, the system was beginning to impact Newfoundland, though there as well amounts were limited, mostly localized to the Avalon Peninsula, with some sea-effect snow on the island's western shore.
The snow will have diminished to flurries by Sunday morning in Newfoundland. Regionwide, 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.
