A powerful winter storm is causing havoc across the north-central US while the rest of the country experiences an unexpectedly warm Christmas.

The National Weather Service (NWS) reveals record-high temperatures in Minnesota and Wisconsin.

The NWS warns of a strengthening low-pressure system, forecasting blizzard conditions, heavy snow, freezing rain and strong winds in the Plains and Upper Midwest through Tuesday night.

Dense fog disrupted holiday travel in Illinois, canceling hundreds of Christmas Eve flights at Chicago’s Midway International Airport.

The storm is expected to bring snowfall and blizzard warnings for South Dakota and Nebraska.

Canada also experiences an unseasonably warm winter, attributing the phenomenon to El Nino and human-caused climate change.
