An extreme cold warning remains in effect for Saskatoon and area. Environment Canada says dangerous wind chill values of minus 40 or colder will occur at times over the next few days.

Overnight low temperatures approaching minus 30 coupled with winds of 10 to 15 km/h will produce extremely cold wind chill values of minus 40 to minus 45 degrees.

The national weather forecaster says snow pushing in from the United States will likely keep regions between the international border and the Transcanada Highway above extreme cold thresholds Tuesday morning. However, areas to the north, in the vicinity of the Yellowhead, will continue with the bitterly cold temperatures into Wednesday morning.

Temperatures are expected to moderate for most by Thursday.

The extreme cold warning encompasses an area from the Alberta to Manitoba boundaries as far north as Meadow Lake on the west side of the province and Yorkton on the east side. It includes Saskatoon and Prince Albert and all areas south to the U.S. border.
