Tuesday:
Despite starting out like the perfect September day, unsettled conditions will take hold of Nova Scotia as a surface trough tracks across the area through the day. This trough will tap into a bit of atmospheric instability, helping to trigger isolated thunderstorms.
Afternoon high temperatures will be slightly above seasonal, so with a little day-time heating combined with the cooler air aloft, it could generate enough instability to spark off storms.
The greatest threat with thunderstorms that develop will be heavy rain, strong wind gusts, and small hail.
There's also the risk for intense lightning and brief downpours from just west of Halifax through to New Glasgow.
The window of timing for storm development will likely be between 2 and 7 p.m.
On Saturday, Halifax picked up 86 mm of rain, with 110 mm of rain falling a short drive away in Bridgewater. This turned into one of the top-eight wettest days ever recorded in Halifax—no small feat when many of the other contenders on the list were full-blown tropical systems.
Gusty winds also knocked out power to some neighbourhoods across the province. Halifax saw a maximum gust of 71 km/h during the weekend storm.
Beyond Tuesday's storm threat, conditions will remain relatively quiet. Temperatures will be slightly cooler on Wednesday before trending warmer again late week. Daytime highs in the mid to upper 20s are expected for the Maritimes.
