Winter has settled in across northwestern Ontario.
CKDR Meterologist Bill Laidlaw says the snow will eventually stop Wednesday night and then things will change.
Laidlaw says some pretty cold air is sliding in behind the Colorado Low across northwestern Ontario.
He says temperatures will reach -18 to -20 heading into the weekend.
Laidlaw notes it will start warming up on Monday and then we can anticipate a roller-coaster ride heading into Christmas.
