Lake-effect showers return to southern Ontario

Digital writers

Friday, October 27, 2017, 7:48 AM - Ontario's work week is closing out with a shot of snow in the northwest, ahead of lake-effect showers that are set to spread across the south.

Special weather statements and at least one snowfall warning were in effect for areas off of Lake Superior early Friday morning. Areas closest the lake should see a few more centimetres, about 2-4 cm according to Environment Canada, before tapering off through the morning. Some areas will have picked up 15-25 cm through to Saturday morning.

It's the cold front from that system that people in the south should keep an eye on, tracking in beginning in the afternoon in the southwest and reaching the GTA overnight into Saturday morning.

As it tracks through eastern Ontario Sunday, it will slow down somewhat and tap into Atlantic moisture ahead of a developing nor'easter, potentially bringing very heavy rainfall Sunday into Monday as the nor'easter itself tracks northward, with the potential for extreme totals in Quebec, along with very strong winds.

Check back for updates as we continue to monitor the interaction between these systems.
