Some snow and a big cool down is forecast for southwestern Ontario Tuesday into Wednesday.

Environment Canada Meteorologist Steven Flisfeder said a significant cold front will sweep into area from the north.

“There’s a system over northern Ontario that’s going to bring a lot of cold air down towards southern Ontario through the next couple of days, and associated with that will be the colder temperatures and the snow.”

Flisfeder said high temperatures around 4 C, 39 F, Tuesday and Wednesday will be about 10 degrees below normal, but it appears Sarnia-Lambton won’t see significant snow accumulation.

“Closer to the lakeshores it’s going to be rain-snow mixed, so accumulations should be on the lesser side,” he said. “The models are still wavering back and forth, but the general 401-corridor looks to be the hardest hit.”

Flisfeder said areas to the east could see around 5 centimetres to 10 centimetres of snow, two to four inches.

He said it’s not unusual to see snow in April but mid-month accumulations don’t happen much.

“The last couple of years we’ve had at least snow, and a couple of years ago we had an ice-pellet storm in mid-April. It’s kind of more unusual to have accumulating snow in mid-April — I think the last time this happened was probably about 50 years ago,” he said. “Spring in general is kind of swing-for-the-fences one way or the other — you never really know what’s going to be landing on the ground, if it’s going to be beautiful sunshine and 20 degrees, or if it’s going to be near zero with accumulating snow.”

Flisfeder reminds drivers to adjust to changing road conditions.

“I’m sure a lot of people have already removed their snow tires, seeing as how it has been fairly warm the past few weeks. So if anybody needs to be on the roads it’s a good idea to take your time. If you can avoid being on the roads during the snow, please do so — it’s safer to be at home at this point.”
