Fall has yet to officially arrive, but Canada is seeing signs of the cold weather that's ahead. Frost is in the forecast in parts of Alberta and New Brunswick this weekend.
Temperatures in these areas struggled to reach the double digits on Saturday. Overnight temperatures were forecast to be around the freezing mark.
Cold temperature is one the ingredients needed to create a frosty Sunday morning.
Gerald Cheng, a meteorologist here at The Weather Network, explains the other ingredients for frost.
“We have high pressure for Saturday night, which means it's going to be clear. Combined with light winds, that's why we'll see ground temperatures drop significantly,” he says.
Frost warnings, issued by Environment Canada, cover a large part of southern and central Alberta -- including Calgary, Edmonton, and Grande Prairie. Frost warnings are also in place for western New Bruswick, including Edmundston and Campbellton.
Early frost has already appeared in parts of Canada over the late summer this year. The frost is worrying farmers, particularly in the Prairies, where heavy rains since the spring have devastated crops.
