After a week off, winter has punched in and gone back to work.

     Snow and blowing snow earlier this week caused some tough times on southwest roads, with white-out conditions on many area highways.

     Now, dangerous wind chills of -40 and colder are expected.  Wind chill warning is out for Swift Current and area, as well as many other areas of Saskatchewan.

     Environment Canada Meteorologist Jim Slipec says a cold air mass has settled in all across the prairies, and with winds picking up to at least 20km/h, extreme wind chills are expected.  He adds, with the wind chill factors, frostbite can occur on exposed skin in 10 minutes or less.

     Slipec says we should get a break from the extreme wind chills this afternoon, as temperatures slowly warm up, but are expected to return overnight and tomorrow morning.
