Convective Discussion
Scattered thunderstorms are expected across New Brunswick, Prince Edward Island and Labrador today associated with a trough tracking slowly southeastward. CAPE values near 500 J/kg are expected in the Maritimes and 500-1000 J/kg over Labrador. Effective shear near 30 knots is expected over the Maritimes and 20-30 knots over Labrador. These conditions will enable some cells to become organized but should remain below warning criteria. Dry mid-levels will support gusty winds this afternoon. Tonight there is a chance of non-severe embedded thundershowers near and ahead of the trough. On Friday, the trough will track across Nova Scotia. Scattered thundershowers are likely near and in the clearing skies in the wake of the trough. Limited CAPE values near 500 J/kg should contain the thundershower activity to less than severe.
