Thick fog is causing near-zero visibility in some parts of the province early Wednesday morning.

Environment Canada has issued a fog advisory for much of western Manitoba. The national forecaster says that the fog is reducing visibility to 500 metres or less in many of the affected areas. 

Meteorologists also warn that the fog could create icy surfaces resulting in poor driving conditions.

The fog is expected to lift Wednesday morning as a cold front moves in from the west. Snow and high winds are expected to move into western Manitoba during the daytime on Wednesday.

Snow and cold on the way

Winnipeg and areas further west may see flurries in the afternoon, and then snowfall is expected to begin in the evening, with 2 to 4 cm expected.

Temperatures will begin to drop Wednesday evening and daytime highs will hover between -16 and -20 the remainder of the week. Overnight lows will be -20 or colder into the beginning of next week.

Snowfall warnings in the north

Meanwhile, in the far north of the province, much of that region remains under a snowfall warning. 

A low pressure system brought snow to the region on Tuesday and it's expected to continue Wednesday before tapering off.

Snowfall totals are expected to be between 10 and 15 cm for most of the region.
