Convective Discussion:
A low approaching from the Great Lakes area will track across the region on Wednesday. There are already rainfall warnings in effect for areas of New Brunswick and they will be expanded to the southwest and issued for areas of central and western Nova Scotia. No surface based convection is expected however the mid level instability ahead of the low is quite significant and is represented in very low Showalter indices. Gusty winds up to 60 km/h are possible. PWAT values of 40-50 mm enhance the downpour threat and that is evident in observations currently coming out of areas of New England where 25 mm/hr or higher have been reported.
