Atlantic: Severe thunderstorms threaten heavy rain, powerful winds

Sunday, July 21st 2019, 10:10 am - A cold front is on its way across the Maritimes, bringing another threat for thunderstorms and severe weather.

Atlantic Canada can still expect toasty temperatures for the remainder of the weekend. Nova Scotia and New Brunswick remain under a heat warning, and can expect warmer temperatures for Sunday, coupled with the risk for showers and thunderstorms.

While heat warnings remain in effect for parts of Atlantic Canada, temperatures are expected to cool down to seasonal values next week as a new system moves in, that could bring heavy rains, powerful winds, and even the slight chance for tornadic activity in New Brunswick.

More on how long this heat wave will last, and the timing of the next round of severe weather, below.


WEATHER HIGHLIGHTS:

  • Risk of showers and non-severe thunderstorms for the Maritimes

This cold front has the potential to act as a trigger for severe storms for Sunday.

The heat and humidity will continue to be uncomfortable on Sunday with temperatures in parts of New Brunswick and Nova Scotia nearing the 30-degree mark. Humidex values will be in the low- to upper-30s across the Maritimes.

Newfoundland will remain outside of the heat and will continue to have temperatures near or slightly below seasonal.

COOLER TEMPS, MORE UNSETTLED WEATHER NEXT WEEK?

Looking ahead, a new system is expected to pass through, bringing a new risk for widespread rain in the region early next week.

This will bring the threat for significant downpour around Tuesday for Nova Scotia and New Brunswick.

“Cooler weather for the middle and end of next week but trending warmer for next weekend. Warmer than normal for the following week as we make the transition from July to August,” said Weather Network meteorologist Dr. Doug Gillham.
