If mom is a gardener, it probably wasn't what she wanted to see.
But frost was on the ground early Sunday morning after temperatures dipped near freezing overnight in parts of southern Ontario.
In the spring, Environment Canada will only issue a frost warning in this region after May 7. The Mother's Day frost warning was therefore the first of this season – but it won't be the last.
Environment Canada has already issued another frost warning – this time for Monday morning. It covers areas like Barrie and Shelburne.
“It's the changing of the seasons. Frost warnings happen in the spring, and in the fall. Cover up your plants,” says Brian Dillon, a meteorologist at The Weather Network.
Temperatures climbed to the high teens in southern Ontario over the weekend, and they're forecast to do the same throughout much of the coming week.
A system in the United States will generate southerly winds, resulting in a temperature boost throughout the region.
“There's a good chance for temperatures to be above seasonal by the middle of the week – in the low 20's,” says Dillon. But it could feel even warmer with the humidity.
