A large polar vortex covering all of central and eastern Canada continues to dominant and provide the cold and unseasonably conditions. A shortwave along the southern periphery of the vortex will help to develop a weak storm system that will approach the area from the west and bring the chance of some rain and snow for early tomorrow. This is not a big system by any means, mainly a nuisance. Some light accumulations are possible, mainly north and west of the city.
