Friday morning may have started off unseasonably mild in Windsor, but ice and snow soon started to form as the temperature plummeted.
Environment Canada issued a special weather statement because of the expected drop and the changing precipitation that will come with it.
"We're looking at a transition from rain to snow in the Windsor area between about 7:00 a.m. and 10:00 a.m. this morning," said meteorologist Geoff Coulson. "During that time frame, also the chance of some freezing rain."
Coulson said that lower Mich. had experienced that cold transition early Friday morning, and many areas have already gone over to snow.
About 2 cm of snow is expected today, but Coulson warns it will be slippery.
Roberta Harrison, maintenance coordinator for Windsor's Public Works Department, said the city's salt trucks rolled out around 8 a.m. to get a layer down before the freezing began.
Crews focused on the main roads, but she said residential streets could also be salted if they turned into skating rinks.
"If it's dangerous and warrants attention then we'll go out and salt the side streets."
The massive swing in temperatures could cause potholes to start "popping up everywhere," Harrison added.
