Severe storm risk for parts of the east coast while other areas see snow

With the calendar moving ever closer to the weather beginning of summer, you wouldn’t know it in parts of Atlantic Canada this weekend. While the Maritimes will see showers and thunderstorms on Saturday, parts of Labrador will turn back in time with a snowfall — 20 to 40 cm for higher elevations. Sunday will be dry on the East Coast, but temperatures will dip early next week. More on what to expect for your upcoming weekend below.

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

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

The cold front is expected to initiate a line of thunderstorms across central and northern New Brunswick early to mid-afternoon and is expected to track south.

Some isolated severe thunderstorms may be possible in this cell line, bringing the threat of small hail, strong local 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 re-develop and move into the same area.


Ahead of the front, isolated to scattered showers and light thunderstorms may also develop in parts of Nova Scotia and Prince Edward Island.

Precipitation will also continue to spread eastward across Newfoundland on Saturday as the low spreads, with steady rain for a mostly soggy day on the island. Until Sunday, between 20 and 50 mm are expected, depending on the location.

“This will be one of the heaviest precipitation events of the past month for the province,” said Matt Grinter, meteorologist at The Weather Network, adding that we would have to go back to the end of April for the last 30 to 50 mm. rainy event for the region.



Meanwhile, if you live in Labrador, you get winter treatment. A surge 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 are on track to see 20-40cm of snow at higher elevations on the Labrador coast, with minimal totals at lower elevations .

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

People across the Maritimes can expect a warm start to next week, but conditions will become much cooler and more choppy as June approaches. Daytime highs in Newfoundland will only reach the single digits.

However, warmer weather will spread west to east across the region over the weekend and weekend.
