A frost advisory was issued for several areas in Alberta on Wednesday, just days after heat records were broken in Edmonton and in Calgary.
Environment Canada said temperatures were expected to fall to freezing overnight as skies clear and light winds pick up.
The weather agency issues the warnings when temperatures drop to freezing during the growing season. The frost can potentially damage plants and crops.
