Convective Discussion
A trough stretching from western Labrador to the St. Lawrence River Valley will likely spark some non-severe thundershowers over northwestern New Brunswick and central Labrador today. MLCAPE values are expected to be near 500 J/kg and the shear will be 20 to 30 knots. Current soundings indicate a layer of warm air above 500 mb which should keep storms from reaching severe status. The main hazards with any storms will be small hail, strong wind gusts, and locally heavy downpours. On Monday, a low developing in the trough will give a risk of embedded thundershowers across the Maritimes. Localized downpours are possible with any thundershowers that develop.
