There is a risk of frost across Newfoundland, northern New Brunswick, and western Cape Breton on Monday.
The ideal conditions for frost are in place: Light winds, clear skies, and ground temperatures around zero.
Frost warnings began appearing in Atlantic Canada and the Prairies in the late summer. While frost could be in store once again in Atlantic Canada for the start of the week, the Prairies are feeling warm.
Frost warnings have begun to pop up in other parts of the country. Farmers, of course, want the frost to stay away as long as possible because it's harvest time. Prairie farmers and Ontario wine growers are keeping a close eye on the Fall Outlook.
If you think it's a little too soon for the sight of frost, then just take a look at this: Snow. It's already shown up in Yukon.
