Regional Impacts
Labrador.. chance of a few isolated thunderstorms later today and this evening. For tomorrow a low risk of severe thunderstorms over western areas with some potential for significant wind gusts.
Convective Discussion
After the passage of the cold front yesterday, most of the Atlantic Provinces will remain relatively quiet with respect to thunderstorm activity today and tomorrow. Most of the preferable dynamics are well north across northern Quebec, moving into western Labrador later today. Low level moisture will be the biggest limiting factor but dewpoint temperatures are expected to increase into the mid-teens tomorrow. With ample shear over 50 knots to 6 km and decent moisture it will largely be a question of timing, if daytime heating is sufficient and the weak upper ridge breaks down early enough there is some potential for severe thunderstorms later in the day. Most of the shear is straight line but there is some potential for supercells to develop, looking for long lived cells on Satellite will be helpful, should they develop.
