If someone tells you to chill, it won't take long if you step outdoors, even if you are bundled up.
An extreme cold warning is in effect for the region, with wind chill values around -30 expected Thursday night into Friday morning, and again Friday night into Saturday morning. Environment Canada says in a statement that "frostbite can develop within minutes on exposed skin, especially with wind chill." Young children, older adults, people with chronic illnesses, those without shelter and anyone working or exercising outdoors are at greater risk, it adds.
There is also a risk of localized snow squalls blowing in off Georgian Bay and Lake Huron through Friday as the wind gusts to 60 km/h.
In what has been a relatively mild winter, this blast of Arctic air will come as a shock to the system.
The cold will blanket the entire province.
However, the deep freeze will not last long. The temperature will begin to rebound at the weekend and possibly climb a few degrees above the freezing mark next week with a risk of showers.
