Snow Squall watchIssued at 10:54 AM EST Wednesday 11 December 2013
1. Snow squalls with cold front crossing Eastern Ontario. Bands of flurries, heavy at times are extending well inland from Georgian Bay, and will continue to extend all the way across the National Capital Region this morning. Meanwhile a sharp Arctic cold front approaching from the north will move towards the regions this afternoon. This front may cause the snow bands to intensify into an intense snow squall as it moves through. The front will reach the Haliburton to Ottawa to Alexandria areas this afternoon, then push southward towards the St Lawrence River and Lake Ontario this evening. Sudden near zero visibility in bursts of heavy snow and local blowing snow are quite possible especially if the snow squall develops. Snowfall rates of 2 to 5 cm per hour are possible with the heaviest snow squall, with local accumulations of 5 to 10 cm possible depending on how long the snow squall lasts over a particular locale. Motorists should be prepared for dangerous winter driving conditions due to sudden nil visibility in bursts of heavy snow and local blowing snow. The cold front and snow squalls are expected to move to the south of the regions by midnight. 2. Remaining regions near Lake Huron and Georgian Bay. Flurries with risk of snow squalls today to Friday morning. Strong winds continue to generate lake effect flurries off the open waters of Lake Huron and Georgian Bay. The flurries are expected to be heavy at times with a risk of snow squalls and snow fall amounts of 5 to 10 cm per 12 hours. Locally higher amounts will be possible southeast of Lake Huron and Georgian Bay this evening when the squalls are expected to intensify. Motorists should be prepared for poor visibilities in snow and blowing snow.Details
