Convective Discussion
A weakening cold front will track southeastward to lie over the St. Lawrence River tonight and over a line stretching from Newfoundland to New Brunswick on Friday. There is not much shear (20 to 30 knots and linear) and the ML Cape is 500 J/kg or less. PWAT values of 35-45 mm may allow downpours if the convection initiates. Dry mid levels support the model guidance suggested wind gusts to 70 km/h. Guidance is suggesting that hail will not be a factor.
