Americans are bracing for frigid temperatures that forecasters say could produce life-threatening conditions. Donald Trump’s inauguration is expected to be the coldest in 40 years. The bitter weather, tied to an Arctic “polar vortex” blast, is expected to bring nighttime lows as cold as minus 23 degrees Fahrenheit (minus 31 degrees Celsius) over the weekend for some of the northernmost parts of the United States. President-elect Trump, who takes office Monday, will see his swearing-in ceremony in Washington hit by freezing temperatures and winds of up to 30 miles per hour.
