It looks like the first major snowfall of the season is on the horizon.

Earlier today, Environment Canada issued a special weather statement for much of the region as a developing low pressure system is expected to bring heavy snow starting Wednesday evening.

The snow is expected to continue through Friday before tapering to light snow or flurries by Saturday.

While it's currently unknown how much snow is expected to fall, Environment Canada says some parts of the region could see between 20 and 40 cm of snow by Friday evening, depending on the track of the storm.

The snow will be accompanied by strong winds at times which could result in reduced visibilities due to blowing snow especially on Thursday and possibly Friday.

Winter storm watches or snowfall warnings may be issued as the event draws nearer.
