A Winter Storm Watch has been issued for most of northwestern Ontario, calling for 15 to 25 centimetres of heavy and blowing snow, with limited visibility on the roads.

Winds are expected to hit up to 60 kilometres per hour with possible rain and lows near minus 1 overnight.

Roadways are expected to be slick tomorrow and drivers are asked to keep a close eye on conditions. The watch may also be upgraded to a warning at any time.

Things look to clear up by Friday afternoon with temperatures around 4.
