Regional Impacts
Slight risk of a non-severe thunderstorm over southern portions of the interior of Newfoundland later this afternoon.
Convective Discussion
Over Newfoundland, an area of surface based instability is expected to develop later this afternoon over unpopulated interior areas of the island. This is supported by a weak disturbance embedded in the strong northwesterly flow aloft. One condition for the destabilization to occur would be for the current cloud deck to break-up/scatter out which should happen beginning over the west coast during the early afternoon, then later over inland areas.
Warm and dry conditions will prevail over the Maritimes today.
Thunderstorm Outlook for Day 1
Thunderstorm Outlook for Day 2
Hot and somewhat more humid conditions are in store for Friday across the Maritimes. Some of this (modified) airmass will try to push across Cabot Strait into southwest NF. Temperatures profiles over NB are supporting the potential for the development of an isolated thunderstorm, especially with the help of forcing from hills and where forest and other vegetation may provide the extra moisture and energy needed.
