Winter Weather Travel Advisory in effect for Thursday.
Snow squalls are expected to develop. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow, and snow will quickly accumulate.
Conditions are favourable for a period of lake effect snow squalls off Lake Huron and Georgian Bay Thursday evening into Friday. These will be the first significant snow squalls of the season.
Snow squalls are likely to develop to the southeast of Lake Huron and Georgian Bay Thursday evening and will persist well into the day Friday. Under the snow squall bands, visibilities will be significantly reduced due to heavy snow combined with blowing snow. Total snowfall accumulations in excess of 15 cm are possible for areas that receive multiple snow squalls.
A cold front will move over Southern Ontario prior to the development of snow squalls, which will rapidly reduce temperatures to the freezing mark. This will change rain showers to flurries, leading to locally icy surfaces near the afternoon rush hour.
Travel may be hazardous due to sudden changes in the weather. Visibility may be suddenly reduced at times in heavy snow. Public Safety Canada encourages everyone to make an emergency plan and get an emergency kit with drinking water, food, medicine, a first-aid kit and a flashlight.
