A heavy snowfall expected tonight.
It may be the first full day of spring, but it’s no surprise that mother nature is still in a wintery mood. A potent disturbance currently over Minnesota is expected to carve a path across Southern Ontario tonight with the centre of low pressure likely to cross the Toronto area after midnight.
A period of heavy snow is expected beginning late this evening near Lake Huron reaching the Blue Mountains and Collingwood area shortly after midnight. The snow is expected to be very heavy at times with snowfall rates of more than 3 centimetres per hour. Although the duration of snow is not expected to be significant, the accumulation of heavy snow will likely exceed 15 centimetres before it tapers off later tonight near Lake Huron and over Eastern Ontario Saturday morning.
Travellers are urged to use caution tonight into Saturday morning due to visibilities of 200 metres or less in heavy snow as well as significant and rapid accumulation on untreated roads.
