Fall Windstorm With Wind Gusts Up to 90km/h Across Southern Ontario Starting Sunday Evening

It’s going to be a wet, windy and snowy start to November for Southern Ontario as an Alberta clipper is moving across our region. Sunday started quite mild by November standards with temperatures early this morning reaching into the mid to upper single digits and heavy rain courtesy of the Alberta Clipper. The clipper is starting to move out of our region this afternoon and behind it will be colder temperatures bringing much of Southern Ontario to near or below the freezing mark by Sunday evening and into the overnight. Lake effect snow will also develop off of Lake Huron and Georgian Bay bringing potentially up to 20cm of accumulation to some regions south of Georgian Bay and southwest of Lake Huron by Monday afternoon.

We are already seeing some gusty winds this afternoon and they will only become stronger as we head into the evening with potentially damaging wind gusts. The strongest gusts will be found around Georgian Bay and Lake Huron with gusts exceeding 90km/h and even approaching 100km/h right along the shoreline (particularly the Grand Bend, Goderich and Kincardine area). Away from the lake, we’ll still see strong winds ranging from 70-85km/h which could bring down some small tree branches and cause localized power outages. This will last overnight into Monday morning with the wind gusts subsiding after sunrise.

These strong wind gusts are expected at the same time that strong snow squalls could develop around Georgian Bay and Lake Huron overnight and into Monday morning. As a result, blowing snow and near-zero visibility is quite likely in the affected region so be sure to drive according to the conditions especially since this is the first big snowfall of the season.
