Convective Discussion
Over portions of western New Brunswick today, daytime heating combined with troughing and afternoon clearing will likely initiate surface driven convection later this afternoon and into this evening. CAPE values of 500-1000 J/kg and shear of 40-50 knots are expected. Near severe to severe thunderstorms are possible in this environment. Elevated convection is possible tonight over portions of western and central New Brunswick associated with 850 mb thickness ridging.
On Sunday, a warm front will approach New Brunswick. Once again, CAPE values of 500-1000 J/kg and shear of 40-50 knots are expected. Near severe to severe thunderstorms are possible.
