Convective Discussion
It continues to be an interesting summer with most of the Atlantic region wedged between the remnants of Idalia and building ridge of high pressure. In terms of thunderstorm potential this will not be a very strong set up, however a weak upper trough could trigger some thunderstorms over eastern Labrador and west of the Maritimes in Quebec and Maine. As the moisture associated with Idalia creeps slowly northeastward there will be slight risk of a thunderstorm near the low. It is likely that most of the heavy precipitation will remain south of Nova Scotia, but there is a slight chance with higher PWAT value coming onshore over southeast Newfoundland that a few heavier showers could happen tonight and tomorrow. Tomorrow over Nova Scotia there will be a slightly enhanced chance of convection near the vicinity of the low pressure system, but the probability will remain quite low for heavier showers or thunderstorms.
