Convective Discussion
Most of the region will see stable conditions today with very little potential for convective weather to develop. There is however some favourable dynamics coming together over central Newfoundland for this afternoon and early this evening. The main two being the upper level Jet and the slow moving surface trough slowly crossing over the island later today. In general low level moisture is not overly favourable but afternoon dew points could reach 12 degrees which given sufficient solar insolation could generate some weak thunderstorms. The overall balance between shear and updrafts will likely not be sufficient for any organized convection however given the very low freezing levels (< 9000 ft AGL) small hail is likely. Thunderstorms should they develop should be concentrated just ahead and in the surface trough where convergence will be a contributing factor.
