Regional Impacts
Isolated non-severe thunderstorms over central and eastern NB to the Bay of Fundy, Annapolis Valley and northwestern NS, also southeastern Labrador.
Convective Discussion
This morning an upper trough extends over the Gulf of St. Lawrence and eastern portions of the Maritimes, with extensive cloud&rain detected on Sat and Rad. A northerly jet streak and some other upper support will maintain unstable conditions and trigger the development of isolated thunderstorms just behind the trough. Further to the west, conditions will generally begin to dry out as a ridge continues to build over Ontario and western Quebec – this is a prelude to the arrival of the next warm airmass.
Another area for potential thunderstorm development is over southeastern Labrador where a surface trough currently over the mid coast will continue to progress southward. Sat imagery is already indicating the presence of glaciated towering cloud tops over the mountains east of Goose Bay. These storms may become somewhat organised (along the trough) and present the appearance of a solid line. Winds may gust between 50 to 70 km/h ahead of these storms.
