Regional Impacts
Today.. Isolated Thunderstorms giving some locally heavy downpours up to 25 mm, some stronger gusts possible.
Convective Discussion
The most favourable dynamics have shifted to lie just of the coast of Nova Scotia, in terms of upper support for prolonged and organized convection that will continue to diminish through the day. However there is still a decent amount of moisture in the atmosphere and surface dew point temperature will be in the high teens or even 20 C in some areas. Thunderstorms started early over eastern areas where a week trough was able to help trigger some smaller thunderstorms. As daytime heating continues there will be a slight chance of thunderstorms developing over areas including SW Newfoundland and NW New Brunswick. Moderate Cape could potentially lead to some heavier downpours and gusty winds. Wind gusts are not expected to be at warning level but if deeper thunderstorms develop it there may be a slight risk.
Dynamics will become more significant over the next couple days with a chance of organised convection on Tuesday. More details can be expected as we move into the shorter range.
