After a day or two of relief, Extreme Cold Warnings are again in effect for virtually all of Saskatchewan on Wednesday.
Environment Canada says wind chills ranging from -40 to -50 can be expected, frostbite can occur in minutes in these conditions.
A ridge of high pressure is forcing Arctic air to move south, causing temperatures to plummet.
The extreme cold is expected to persist for much of the province for the rest of the week, with a slight warm up on Friday only.
By Tuesday next week Regina is expecting a high of -3.
