Convective Discussion:
Isolated/embedded thunderstorms are possible over Newfoundland this afternoon. Over northern New Brunswick, surface based convection may develop this afternoon and Friday afternoon. It is also possible for Newfoundland Friday afternoon. MLCAPE near 500 J/Kg is anticipated. For both days there is a cap near 700 mb so it may inhibit initiation. Not much of a trigger other than diurnal heating and a supportive 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.
