Discussion
This will be short discussion as thunderstorms are already moving through some areas. This line below may serve as the trigger for severe weather later this afternoon for NB. There is some potential for a weak mesoscale system to develop which could lead to heavy rain and some stronger wind gusts. As of right now a lack of solar insolation could also somewhat limit this potential, therefor the worst areas for severe weather treat will likely be further east.
In Nova Scotia and into PEI where surface temperatures are going to be slightly warmer and the total precipitable water values are around 50mm there will be better chance for local flooding should thunderstorms develop.
NFLD will likely continue to get similar thunderstorms to what they have had over the last few days with isolated or somewhat loosely organized areas giving up to 25mm or so of rain.
