Later in winter it could shift the odds towards cold and snow, something that can be influenced by changes in the polar vortex but none of this is certain.
The polar vortex is a ring of strong westerly winds encircling the North Pole every winter, around 10-30 miles (16-48km) above the Earth's surface.
