Bundle up--a lot.
Environment Canada has issued an extreme cold warning for Windsor-Essex and Chatham-Kent due to a prolonged period of very cold wind chills.
Temperatures will fall tonight to -20C, but with the wind chill, it will feel more like -30C.
Windsor-Essex has had 13 straight days of temperatures of -5C or colder and Warning Preparedness Meteorologist Geoff Coulson says he couldn't find a longer stretch dating back to at least the late 70s.
"Certainly we are used to getting in late December or January, a cold snap or a few cold days here and there where the temperature really dips," says Coulson. "But for it to last this long and this cold doesn't happen very often."
The bitterly cold weather and winds will continue until Saturday morning.
