Convective Discussion
A warm and humid air mass will approach New Brunswick on Friday ahead of a low pressure system moving eastward over Quebec. The atmosphere will be conducive for the development of thunderstorms in the afternoon given increasing moisture in the low levels, moderate low level wind shear and high maximum temperatures. These ingredients along with an approaching cold front will help de-stabilize the air mass and initiate afternoon showers and potential thundershowers over northwestern New Brunswick beginning in the afternoon and spread southeastward into the evening.
Regional Impacts
The main threat with the potential thundershowers will be local heavy downpours and some moderate gusts.
