Convective Discussion
We will begin to see some movement on the very warm air mass that has bee situated over the region for the last several days as a cold front slowly moved over Quebec today. A broad area of showers and thunderstorms will slowly move over New Brunswick and Labrador today, making its way over Nova Scotia and Newfoundland tonight. The dynamics for severe weather should be better today than it has been for the last few days with about 30 knots of deep shear over New Brunswick and Labrador making the likelihood of longer lived thunderstorms much higher. Convergence should be sufficient today near the trough line to initiate thunderstorms which are already occurring in Maine and Quebec. Severe Thunderstorm watches could potentially be issued this afternoon should some deeper convection begin to form over the area.
