Severe storm threat with strong winds over the Maritimes Friday
Rising heat in Atlantic Canada coincides with an increasing storm risk for Friday. Humidity set to break by Saturday with a noticeable cooldown
Following a week of extreme heat south of the border, severe storms have been moving through central and eastern Canada since Wednesday. Large hail, damaging winds, and power outages hit both Ontario and Quebec on Thursday.
The train of storms will conclude in the Maritimes Friday, with powerful winds as the main threat for impacted regions.

Make sure you keep an eye on the radar––especially if you have outdoor plans––and stay aware of any severe weather watches or warnings issued in your area.
Severe storm threat takes aim for Friday
In the Maritimes, inland temperatures could reach 30°C in Nova Scotia and southern New Brunswick on Friday, with humidex values climbing to 37–40 in southern New Brunswick.

The intensifying heat and humidity are expected to fuel thunderstorm development across the region.
Bay of Fundy sea breezes and the Fundy Highlands may contribute to enhanced storm activity over southern New Brunswick later Friday evening. Both Fredericton and Moncton are expected to see impacts. However, as the advancing front pushes storms into central New Brunswick earlier in the day, they are expected to weaken and become less widespread in those areas.

Storms crossing the Bay of Fundy are likely to lose intensity, transitioning to periods of heavy rain with embedded non-severe thunderstorms. A similar pattern is anticipated across western Newfoundland.
The primary hazard will be strong wind gusts associated with the system.

By Saturday, temperatures are expected to feel approximately 10°C cooler due to reduced humidity, bringing relief after Friday’s unsettled weather.

Near seasonal temperatures are expected during the first half of next week, and then trending cooler than normal late next week and weekend. There is the potential for more widespread showers and thunderstorms as we finish off the month of July.
