September 15, 2012 — Environment Canada issued a series of frost warnings for northern Ontario, including Lake Nipigon and Geraldton Friday night. On Saturday morning, it was southern Ontario's turn, with warnings issued for some areas for that evening into Sunday morning.
It's technically still summer, but someone forgot to tell the frost.
Environment Canada issued a series of frost warnings for northern Ontario Friday - including Lake Nipigon and Geraldton - warning of plunging temperatures.
And it seems southern Ontario was not spared. Saturday morning wasn't even over when Environment Canada issued a series of frost warnings for an area stretching from the Peterborough area to the Algonquin and Renfrew-Pembroke-Barry's Bay areas.
The agency says a mass of cold arctic air is making its way through Ontario, and many parts of the province are in for slightly cooler than normal weather on Saturday.
Environment Canada says the frost will end Sunday morning as the sun rises, and is warning people to either cover their more fragile plants or bring them indoors for the night.
Parts of Alberta were also under a frost warning Friday night, with those dropping by the morning. But before the mercury dropped, Friday saw several temperature records broken.
Edmonton International Airport reported 26.5 degrees, breaking a record set in 1979. Bow Island was even hotter, at 31.3 degrees, more than two degrees warmer than the last record, set in 2000.
