It's been a story of never-ending cold across the country, but there's something to look forward to at the end of the week.

Mild air is moving into British Columbia, and those temps will migrate across the country.

"As this welling of cold Arctic air moderates and drifts eastward, a new weather pattern is evolving into place," writes Weather Network broadcaster Chris St. Clair

"It will provide a new track for storms to follow, and perhaps even force the idea of spring into daily discussion."

The phenomenon is called a pineapple express, and forecasters have been talking about it a lot lately.

This weather pattern occurs when a strong area of low pressure develops in the Gulf Of Alaska, west of British Columbia.

At the same time an area of stable high pressure forms over to the south, centered near California.  

This helps draw in moisture from the tropical Pacific -- some of it coming from as far away as Hawaii.

Nearly the entire country -- with the exception of parts of southern Manitoba, parts of Saskatchewan and northern Ontario  -- will see temps climb by Thursday.

In the meantime, it's expected to remain below-seasonal across much of the country, so bundle up.
