Tuesday, February 23rd 2021, 10:08 am - A messy storm system 'overachieved' in terms of snowfall, shutting schools across parts of New Brunswick early Tuesday.
A potent low delivered quite the messy wallop over parts of the Maritimes Monday night, as rain and snow fell through the overnight hours, overachieving in terms of snowfall for pockets of the region. A widespread 10-15 cm of snow was expected in the hardest hit areas, but some reports of locally higher amounts in New Brunswick forced the closure of several schools due to the deteriorating conditions. The system will make its way through Newfoundland on Wednesday, though changing over to rain across the south as milder air pushes in. Beyond, more snow is expected late-week with a strong clipper system, as well as a potential messy weekend low. More on the timing and impact of this active storm set-up, below.
- Snow arrived in the Maritimes Monday night, changed to rain in southern Nova Scotia Tuesday morning
- Locally heavy amounts of snow reported in central and northern New Brunswick, forcing school closures there
- Strong clipper to push in Wednesday night with more snow, anther messy system on the weekend
TUESDAY: HEAVY OVERNIGHT SNOW CLOSES SCHOOLS IN NEW BRUNSWICK, SYSTEM MOVES TO NEWFOUNDLAND NEXT
The same low that impacted Ontario and Quebec through Monday, intensified off the northeastern U.S. coast and tracked into the Maritime provinces Monday night. Snowfall warnings were issued for parts of New Brunswick, with the threat for up to 20 cm to fall in the hardest hit places.
"A widespread 10-15 cm of snowfall was expected, but we've seen some reports of locally higher amounts thanks to a slow-moving band of heavy snow that set up over parts of central and northern New Brunswick," explains Weather Network meteorologist Michael Carter.
Around 15 cm was reported at the Saint John airport, with 11 cm for Moncton. While official snow totals have yet to be reported, heavier pockets of 20+ cm, are definitely not out of the question for northern sections.
The overnight snow prompted the several schools to either cancel or delay openings across the province.
The low pressure system tracking through the Bay of Fundy brought a mix of preciptation to much of Nova Scotia, with most of the rain winding down through the morning hours on Tuesday.
The soggy overnight conditions, combined with the warming temperatures, have also melted a lot of the recent snowpack for southern parts of the region.

SPECIAL WEATHER STATEMENTS WARN OF DIFFICULT EVENING COMMUTE IN NEWFOUNDLAND
As conditions clear across the Maritimes, snow will be pushing into Newfoundland through the day on Tuesday, prompting widespread special weather statements warning of a difficult evening commute.
The snow, combined with strong southeasterly winds with gusts up to 80 km/h could compromise travel times.
A widespread 5-10 cm is expected, with locally heavier amounts possible. The precipitation is expected to change over to rain for southern sections of the island however, as milder air pushes in.
"Atlantic Canada will see a quieter period for most of the day on Wednesday, with only lingering sea-effect flurries, but our next weather system in this active and fast-moving pattern begins to move in as soon as Wednesday night," Carter says.
LOOK AHEAD: MORE CHANCES OF SNOW, RAIN WITH MULTIPLE SYSTEMS
A relatively strong clipper system will slowly strengthen as it tracks into the region Wednesday night and Thursday with 5-10 cm of snow for parts of the central Maritimes, including Moncton and Charlottetown, and 5-15 cm for much of Newfoundland, though the snow could change to rain for the Avalon. Rain is expected for southern Nova Scotia.
Another messy system is likely for Saturday night and Sunday. It is too early to have confidence in the storm track, but a more northerly track is currently expected, which would bring rain for southern and possibly central Maritimes, but with potential for significant snow in Newfoundland.
