Convective Discussion
A departing low pressure system will give a chance of afternoon thundershowers across portions of Newfoundland 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 Sunday, weak troughing over Newfoundland will give similar or weaker atmospheric conditions as today and a chance of afternoon thundershowers.
