A significant snowfall beginning tonight and tapering off Wednesday.
A developing low pressure centre over Louisiana is forecast to track into Southern Ohio overnight. It is already tapping into moisture from the Gulf of Mexico today which will quickly spread northwards throughout the afternoon. Snow is expected to arrive over Southwestern Ontario early this evening and the Golden Horseshoe around midnight. It is expected to reach communities north of Lake Ontario overnight and Eastern Ontario very early Wednesday morning.
Most regions from Windsor to Toronto to Kingston and Brockville will likely have received several centimetres of snow by the Wednesday morning rush hour. The heaviest snow is expected to fall Wednesday morning, impacting the commute for many areas. Commuters should allow extra time due to accumulating snow and reduced visibility in falling snow.
Total amounts of 10 to 15 cm are likely from Windsor to Toronto into Eastern Ontario by the time the snow tapers off Wednesday when the centre of low pressure heads into New England. A snowfall warning is in effect for portions of the Golden Horseshoe to the southwest of Toronto where in excess of 15 cm of snow is expected.
