Snow Squall Watch Now In Effect – 15cm Of Snow For Some Areas

You might see something on the roads today that you have not seen in a while: salters and sanders. Crews are already out pre-treating roads in anticipation of what’s coming. Rain will start late this morning or early this afternoon. The temperature is going to drop rapidly and freeze that rain to the roads. The rain is also going to change to snow. Environment Canada says the drive home today will see quickly deteriorating road conditions. About 2cm of snow will fall in the Toronto area.

There is now a snow squall watch in effect that could producer up to 15cm of snow for other parts of southern Ontario. Here are the details from Environment Canada.

4:45 AM EST Thursday 09 November 2017
Snow squall watch in effect for:

  • Orangeville – Grand Valley – Southern Dufferin County
  • Caledon
  • Innisfil – New Tecumseth – Angus
  • Shelburne – Mansfield – Northern Dufferin County
  • Newmarket – Georgina – Northern York Region
  • Barrie – Collingwood – Hillsdale
  • Midland – Coldwater – Orr Lake
  • Orillia – Lagoon City – Washago
  • Bruce Peninsula – Sauble Beach – Tobermory
  • Hanover – Dundalk – Southern Grey County
  • Owen Sound – Blue Mountains – Northern Grey County
  • Saugeen Shores – Kincardine – Southern Bruce County
  • Mount Forest – Arthur – Northern Wellington County

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 southeast of Lake Huron and Georgian Bay beginning this evening and continuing into Friday. These will be the first significant snow squalls of the season. 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 this afternoon prior to the development of snow squalls and will rapidly reduce temperatures to the freezing mark. This will change rain showers to flurries and lead to hazardous driving conditions. Temperatures will continue to drop well below the freezing mark this evening.

Environment and Climate Change Canada is closely monitoring the situation and will update messages as required.

Travel may be hazardous due to sudden changes in the weather. Visibility may be suddenly reduced at times in heavy snow. Road closures are possible. 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. For information on emergency plans and kits go to www.getprepared.gc.ca

Snow squall watches are issued when conditions are favourable for the formation of bands of snow that could produce intense accumulating snow or near zero visibilities.
