It has been clear in most areas of the region, but according to Environment Canada, snow is on the way for much of the district, including Sudbury.
Environment Canada meteorologist Geoff Coulson said when the snow finally does start falling, it will last for several hours.
"This is going to be turn out to be quite a duration event,” he said.
“So we're going to see it initially as a snow event, beginning overnight and continuing during the day on Thursday. We may see somewhere between 10- to 15 centimeters right across the district."
So far, a snowfall warning has been issued for Wawa.
Coulson said that warning could be extended for other areas in the region, including Timmins, Chapleau and Earlton.
