Convective Discussion
A departing upper low over northern Labrador with an associated surface trough will track across eastern labrador this afternoon. MLCAPE values are expected to be 250-500 J/kg and the effective shear will be 10 to 20 knots so any thundershowers will be weak in nature. On Saturday, an area of high pressure will move across the region so convection is not expected.
