Snow squalls will last through to Thursday but it’s only one piece of the weather puzzle this week. The squalls are actually a precursor to some very cold air arriving tonight and into the weekend. Daytime highs are only expected to reach a chilling -11c and that doesn’t include windchill. Overnight lows will dip to the -20c before some milder air comes back for mid week next week.
For today however, Environment Canada has issued the following.
Snow squall warning in effect for:
Sault Ste. Marie – St. Joseph Island
Searchmont – Montreal River Harbour – Batchawana Bay
Snow squalls are occurring. Under the snow squall bands, visibilities will be significantly reduced due to the heavy snow combined with blowing snow, and snow will quickly accumulate.
Snow squalls will cross the region today. Local snowfall amounts of 10 cm are likely before the snow squalls shift out of the region late this afternoon.
Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow. Travel is expected to be hazardous due to reduced visibility in some locations.
