A low-pressure system making its way through most of Southern Ontario overnight will spread across the Golden Horseshoe.
Heavy snow is expected to bring close to 15 cm of accumulations during the morning and afternoon on Saturday. Wind gusts will create areas of local blowing snow, according to the weather agency.
Snow will turn to rain and light flurries on Saturday night.
“Visibilities will be reduced in areas of blowing snow, which can make travel hazardous,” Environment Canada said in their statement.
Areas around Niagara Falls, Welland, and southern Niagara can expect the same, only with heavier wind gusts which could reach up to 90 kilometres per hour at times.
The general forecast on Saturday is calling for snow and rain with a high of 2 C. The wind chill is expected to make it feel like -14 C Saturday morning.
Flurries will continue on Sunday with a high of -3 C.
