Dr Vinós is calling for a reversing of the warming caused by Hunga-Tonga, and notes that other climatic factors should combine to deliver a period of significant cooling.

76-Hours Of Continuous Snowfall

The deadly blizzard, which proved a record-breaking for the Minneapolis area, is finally winding down.

The Twin Cities received 8.2 inches of snow on Sunday, making for the snowiest March day since 2007.

Many areas of the Upper Midwest picked up much more, going on 2 feet in some spots. Duluth, Minnesota hit 21.6 inches, while elsewhere in Minnesota, Casino picked up 18.3 inches, and Lester Park 16.1 inches.

Portions of Minnesota witnessed 76-hours of of continues snowfall, but things are winding down now, mercifully.

Behind the storm, strong northerly winds will funnel bitterly cold air down from Canada, and thermometers, for many, will read in single digits Wednesday morning—or some 25F below average—which will help keep snow on the ground.

Spring has failed to sprung above the border, too.

Arctic air has been sinking south of late, supporting a multi-day snowfall event that dropped more than a foot of snow across the likes of southern Alberta. This most recent dumping, combined with other late-season blasts, now puts the city of Calgary in the running for its snowiest March on record, breaking the old 1998 when 70.3 cm settled.

With colder air in place, and an unsettled weather pattern, the chances for another 8.3cm (to match the record) are definitely in the offing: "We will have chances to inch closer and closer to the record in the coming days," said The Weather Network meteorologist Rachel Modestino.

Across the North American continent in fact, heavy spring snow will persist:
