Convective Discussion
Some dynamic support exists for convection today, though cooler temperatures and low dew points will limit updraft potential. Any storms that develop may produce locally strong wind gusts due to enhanced downdraft potential.
A low chance of embedded thunderstorms exists over eastern Newfoundland, with no expected impacts.
For tomorrow, a low-probability but higher-impact scenario exists over eastern Nova Scotia if training develops; localized rainfall rates near 25 mm/h are possible.
Sunday may be more active as another upper trough crosses the region. Modest instability and shear could support heavier downpours and small hail.
