Weather tracker: freezing conditions sweep south across US

Cold air from north Canada brings windchill warnings over area stretching down to Mexico border

Much of the United States is currently experiencing very cold conditions as cold air plunges south from northern Canada all the way to the Gulf coast, giving freezing temperatures across the majority of the country.

An area of low pressure in the Great Lakes region brought snow and bitter winds. Eight inches (20cm) of snow was reported in the twin city area of Minneapolis-Saint Paul in Minnesota on Wednesday. The surge of cold air also affected areas farther west, with a sharp cold front bringing a dramatic 22C (40F) drop in just 30 minutes in Cheyenne, Wyoming.
