Reality is setting in across Southern Ontario, reminding us that it isn't done with us just yet, despite the unseasonably warm weather we've enjoyed last week and into the weekend. We're in for a rollercoaster ride as temperatures drop from the 20s and even lower 30s a few days ago to daytime highs struggling to reach double digits in the coming days. The colder air will also bring back a sight we thought was behind us - snowflakes falling from the sky!

Indeed, we are looking at the risk of flurries and wet snow over the next couple of days across much of Southern Ontario. We've already seen some flakes in parts of Deep Southwestern Ontario early this afternoon. The potential for snow will encompass much of Southern Ontario by later tonight and into the overnight hours as temperatures drop to near the freezing mark. We aren't expecting significant accumulation, and with the ground still somewhat warm from last week's heat, much of what falls will likely melt on contact.

However, we do see the chance of minor accumulation east of Lake Huron and Georgian Bay, where lake effect snow could boost snow totals in those regions. Some higher elevations east of Lake Huron through parts of Huron, Bruce, Grey, and Perth counties could see up to 4-8cm of accumulation! Surrounding regions, including Central Ontario, may see a light dusting of snow, especially during the overnight hours when temperatures will be cold enough to allow for accumulation.

Scattered flurries will continue throughout the day on Tuesday, with the heaviest snow found east of Lake Huron and Georgian Bay. It appears Eastern Ontario will mostly escape the snow, as this will be mainly a lake-driven event. However, they could see a few flakes later in the day on Tuesday and Wednesday mornings as the moisture associated with this system moves out of the region.

Keep in mind, actual accumulation may vary due to temperatures being very close to the freezing mark. As such, totals may be lower than forecasted, given the potential for some snow to melt on contact with the ground. It will come down to how cold the temperature can get during the overnight hours, which will dictate how much snow will stick to the ground.

Be sure to take your time on the roads if you need to travel, as many have likely already switched from winter to summer tires. While this won't be a high-impact event, it could cause some delays since drivers haven't had to deal with wintry weather in a while. Stay safe!
