A deep freeze expected in the US Midwest, north-eastern New England states and even the South will be one to remember, with potential record-low temperatures heightening fears of frostbite and hypothermia.
It has not been this cold for decades 20 years in Washington DC, 18 years in Milwaukee, 15 in Missouri even in the Midwest, where bundling up is second nature.
Meteorologist Ryan Maue of Weather Bell said: “If you’re under 40 you’ve not seen this stuff before.”
Preceded by snow in much of the Midwest, the frigid air began yesterday and will extend into early next week, funnelled as far south as the Gulf Coast.
It is being blamed on a “polar vortex” as one meteorologist calls it, a counterclockwise-rotating pool of cold, dense air.
Temperatures are forecast to reach between -26C and -35C.
