Regional Impacts
Isolated non-severe thunderstorms are possible this morning along portions of South Shore NS and offshore across marine areas – slope waters, and Sable Island. Elsewhere across Maritimes the atmosphere is stabilizing.
Convective Discussion
Soundings behind the frontal feature are drying out nicely at 700mb as forecast. This is stabilizing the mid levels of the atmosphere with the noticeable change in air mass. No thunderstorms are forecast overnight tonight across the AOR. Pockets of instability are possible in parts of central Newfoundland tomorrow, along parts of the Lab coast, and across extreme northern NB. No dynamics suggest anything near severe limits. Cells will be embedded in shower activity. Sunday late in the day has the potential to be more organized in NB and NS as a frontal feature amps up dew points and lift indices again. This risk will be honed in on in coming shifts, with a particularly watchful eye on shear.
