Convective Discussion:
Isolated/embedded thunderstorms are occurring associated with a warm front extending from a low southwest of Nova Scotia. As the low occludes tonight, the thunderstorm potential will move eastward to include Newfoundland. On Thursday, elevated thundershower potential will continue for Newfoundland. Over central and northern New Brunswick, surface based convection may develop Thursday afternoon. MLCAPE of 500 -750 J/Kg is anticipated with a favourable diffluent 500 mb environment ahead of an approaching upper low. The shear is very low so if thunderstorms do develop they will be pulse type and very slow moving. Pwat values near 30 mm exist so good downpours are likely with this slow moving system. Small hail and gusty winds are also possible.
