Convective Discussion
Despite the cloudiness, favourable dynamics and high moisture are expected to keep thunderstorms progressing though the day in NB and into NS and PEI this evening and tonight. Locally heavy downpours, exceeding 25mm are possible for some areas today and tonight.
Tomorrow the upper level jet and increasing wind shear may offset the weaker instability especially over the warmer Gulf and Northumberland Straight waters where there is a chance of thunderstorms.
