Monday and beyond

Monday features some residual thunderstorm activity across New Brunswick, Prince Edward Island, as well as the North Shore and Cape Breton regions of Nova Scotia. Storms will likely remain non-severe in nature, but could still pack a punch with some localized heavy downpours.

A bit of tropical moisture will skirt the coast heading into Wednesday, so we’ll have to watch the development for heavy showers and thunderstorm activity. Temperatures will remain a couple degrees above seasonal, but you’ll really feel the humidex in the low 30’s at times for the week ahead.
