Severe storm chance for parts of the East Coast as other areas see snow

Saturday, May 28th 2022, 10:22 am - The East Coast is set to see quite the variation in weather this weekend: A threat of severe storms for parts of the Maritimes while Labrador gets hit with snow.

With the calendar inching ever so closely to the meteorological start to summer, you wouldn't know it in parts of Atlantic Canada this weekend. While the Maritimes will see showers and thunderstorms Saturday, parts of Labrador will be going backwards in time with a shot of snow -- 20-40 cm for higher elevations. Sunday will dry out for the East Coast, but temperatures will take dive heading into early next week. More on what to expect for your weekend ahead, below.

A system currently sliding across the East Coast will bring a slug of dynamic weather to the region -- encompassing winter and summer. Rainfall warnings are in place for northern New Brunswick, while wind warnings and special weather statements span parts of Newfoundland and Labrador.

An upper-level trough and its associated surface cold front will trigger widespread showers and thunderstorms across parts of the Maritimes on Saturday.

The cold front is forecast to initiate a line of thunderstorms across central and northern New Brunswick through the early-to mid-afternoon and is forecast to push south.

Some isolated severe storms may be possible within this line of cells, bringing the threat for small hail, locally strong wind gusts and heavy rain. There is a significant amount of moisture present in the atmosphere, so locally torrential downpours are possible.

Localized flooding cannot be ruled out if thunderstorms redevelop and track over the same area.


Ahead of the front, isolated to scattered showers and non-severe thunderstorms may develop across parts of Nova Scotia and P.E.I., as well.

Rainfall will also continue to spread east across Newfoundland Saturday as the low pushes across, with a steady rain making for a mostly soggy day on the island. Through Sunday, anywhere from 20-50 mm is anticipated -- depending on location.

"This will be one of the largest rainfalls over the past month for the province," says Matt Grinter, a meteorologist at The Weather Network, adding that we'd have to go back to the end of April for the last 30-50 mm rainfall event for the region.


Meanwhile, if you live in Labrador, you're getting a wintry treatment. A push of modified Arctic air will bring a late-spring snowstorm to some areas. Special weather statements are in effect.

Between this storm and another opportunity for snow early next week, we’re on track to see 20-40 cm of snow at higher elevations across the Labrador coast, with minimal totals at lower elevations.

A drier Sunday is in store for the region with comfortably warm temperatures.

Folks across the Maritimes can expect a warm start to next week, but conditions will turn much cooler and unsettled as we head into the month of June. Daytime highs in Newfoundland will only reach the single digits.

However, warmer weather will spread from west to east across the region late week and on the weekend.
