Thunderstorm risk for Atlantic Canada

May 25, 2010 — Thunderstorms are pushing into Atlantic Canada this afternoon with some severe in nature.

What a difference a day can make.

Yesterday, New Brunswick was dealing with record warm temperatures. Both Bathurst and St. Leonard broke previous records set back in 2007. It may not have been a record breaking day in Fredericton Monday, but it was still hot none-the-less. The city hit 31.1 degrees and when you factor in the humidex it was feeling closer to 34.

Not only will today be cooler for the region, there's also a risk for severe thunderstorms. The warm and humid air mass over the province is favourable for the development of thunderstorms this afternoon and through the evening. The greatest threat with these storms will be large hail, heavy downpours and damaging winds.

And it's a similar story for areas farther west as well.

A thunderstorm watch has also been issued for Quebec.

An unstable airmass associated with a low pressure system could bring heavy rain, strong winds, hail and lightning to several regions in the central part of the province. Although they could be severe in nature, these storms may provide some relief from the muggy conditions.

Environment Canada has issued a heat and humidity warning as well. To stay comfortable, health officials recommend drinking lots of water, reducing physical activity and staying in cool or shaded areas.
