The long-running cold snap that has most of the province in its grip isn't letting up just yet.

Environment Canada says Calgary, and much of the province, will experience wind chill values between 40 and 45, especially overnight and early in the morning.

Most of southern and central Alberta remain under extreme cold warnings.

"Skies are forecast to clear tonight for many areas, especially over eastern and central regions, allowing temperatures to plummet," the agency said on its website.

"This will produce extreme wind chill values again for many regions by Tuesday morning."

The extreme cold is expected to linger until Thursday, when Calgary should get a high of 9 C.

According toYYC Weather Recordsa Twitter account run bycomputer scientist Rolf Campbell, who developed software topullin Environment Canada data to create weather statisticsit's the longest cold snap stretch since January 1998.

The average daytime high for this time of year is zero and the average night-time lowis 12 C.
